Sapphire Radeon HD 5850 user review

This video card is amazing.You can overclock very easy if u have a good driver software.It handles every game in directx 10 at 40-60 fps with 8xaa( except crysys…yeah this game is a video tester).It runs at 40 C. temp in windows and 65-70 C. when i play games.With a decent processor, this can handle any game at max settings very easily. It’s also very easy to overclock, if you wish to do-so. Plus it uses very little power & supports DX11.Some people have the “gray screen” issue with the 5000 series cards. Fortunately, Catalyst 10.2 fixed it for me.So if u wanna to put this baby on work..u must download the video software from the website.Don’t install them from the cd.If u’ want performance and quality buy this thing.

XFX Radeon HD 5770 user review

My very first true graphics card was a Radeon rage 128 with like 8 or 16mb video ram. I have gone through many Radeon cards and for 180$ this is one hell of a card. Lets face it not many, if none games today support direct x 11 however my nvidia 9800gt did not support my Panasonic resoultion which was because my 9800GT didn’t have a HDMI output connector. The fact is when I grew tired of the Radeon 5850 being out of stock I bought this card and so far hooked to a Panasonic 46″ plasma it has performed outstandingly. If you want maximum performance wait for the 5850 for 5870 but the fact remains 180$ for a graphics card with direct 11 and capable of running L4D at full 1920X1080 resoultion is remarkable. This card almost didn’t fit into my NZXT cases so be prepares it requires some room, for this price this card is outstanding and its in stock woot . I am not a nerd nor going to give anyone a pros or cons verdict. Fact is I’am a gamer so for 180$ this is a great deal and lets face it ladies and gentle men why should anyone pay more than 200$ for a graphics when it will be outdated within a year? Too many manufactures are looking for profit with no gain to consumer experience, all I have to say is watch what you spend and remember corruptions are looking out for any amount of money they can acquire, was this card worth the 180$? So far yes but beyond 200$ is insane especially considering a x-box is 200$

Sapphire HD 4870 Vapor-X 2 Gb GDDR5 user review

The 4870 x2 has been here for a few years now, and has certainly made a place for itself among the graphics card market, rivalled only by possibly-over-the-top cards such as Nvidia’s GTX 295, and recently, ATi’s own HD 5870 (which is also the first DirectX 11 card on the market).
Setting up

The card is huge, taking up the space of two slots (which is to be expected of current cards) but also being long. I found that it fitted nicely in my Full tower case, though one should detemine the size of their case before buying the X2. In my opinion, if you are buying the 4870 X2, you should get a full tower anyway, as the cooling requirements must be considered as well. The card requires two PCI-E power connections- so be sure that your Power Supply is ‘compatible’ with the X2. The card uses the PCI-E 2.0 interface, which boasts higher bandwith, among other features- so be sure that you get a suitable motherboard aswell. Driver installation is easy- drivers are provided on-disk, though the latest online drivers are optimal.
Performance

In-game, the 4870 x2 performs very well- always being not far behind the GTX 295 (which is £100 dearer), and in certain games, it will beat the 295, namely games such as GRID and Fallout 3. At the highest resolutions, the X2 will get a high fps in most games. The difference between the 295 and the X2 is often a matter of a couple of frames per second. On the more demanding games, I used ATi Catalyst Control Centre to increase the fan speeds, as ATi are infamous for the heat that their cards can reach.
Conclusion

The 4870 X2 is indeed an excellent card. It beats the ‘DX11-capable’ 5870, in terms of power and price, and rivals the GTX 295 in terms of performance, for £100 less. In terms of Direct X 11, the fact that the 4870 X2 isn’t capable of the full benefits of DX11 wouldn’t drive me to buy a HD 5800 series card, as DX11 wouldn’t be integrated into games for some time, and by that time, neither the 4870 X2, or the 5870 would be the powerhouses that they are right now.

Therefore, out of the Nvidia GTX 295, the ATi HD 4870 X2 and the HD 5870, I would definitely go for the 4870 X2. HOWEVER, the 4870 X2 needs to be used at higher resolutions on a decent sized monitor. For resolutions below 1680 x 1080, you would be better off going for a Nvidia GTX 260, or an ATi HD 4870.

Sapphire RADEON HD 5870 Video performance, compatibility and other resources

Great news for the graphics card Radeon HD 5870 1GB GDDR5 (PCI-E 2.0) in relation to the provision of models of the previous sale. This is the first such model that supports the new Direct X 11, which happens to version 10 which will be active in combination with the proposed new operating system from Microsoft, called Windows 7. Also available are compatible with HDCP. The maximum resolution supported by Radeon HD 5870 1GB GDDR5 (PCI-E 2.0) is of 2560 pixels displayed horizontally and 1600 pixels vertically, according to the standard classical category. The system RAMDAC operates at 400 MHz x 2. Still remember the ATI Avivo technology, compatibility with Blu-Ray Disc and HD DVD, can manage two monitors simultaneously. Absent instead for Macintosh compatibility.

Sapphire RADEON HD 5870 final verdict

It ’s a combination of technology and technical innovation of the new graphics card available from late September 2009, called the Radeon HD 5870 1GB GDDR5 (PCI-E 2.0) and presented by the greatest exponent of producers specializing in devices for professional graphics or Sapphire. Many features of evolution than previous models. First, in terms of system memory, that beyond a very high amount of 1 GB GDDR5 is proposed in the new type, a step that goes beyond even that GDDR4 which seemed to be the last frontier in terms of technique. Furthermore, compatibility with Direct X version 11 will enable the user to use the adapter in conjunction with the operating system Windows 7. The device operates simultaneously monitor and has three HDMI and HDTV among others.

Sapphire RADEON HD 5870 user review

After writing the opinion about the HD 5770 (I own) for the midrange, it is time to talk about this HD 5870 with DX11 support for high-end market?
Let’s say that the card than the younger sisters that is larger is better to evaluate before purchasing. Indeed, with its 27.7 cm may have trouble finding space in many homes. So before you actually buy it check that the space you need.
The power supply requires two PCI-Express 6-pin, and rear panel are two DVI connectors, an HDMI and Display Port connector.
E ‘includes support technology EyeFinity, through this card will allow us to use up to less than 6 screens simultaneously.
Going to see the technical characteristics, there is a construction technology to 40nanometri, accompanied by the excellent RV870 GPU, clocked at 850MHz. The number of stream processors is 1600 (twice the HD5770), and operate at a speed of 850 MHz. The card has 1GB of dedicated video memory GDDR5 who works at a frequency of 4.8GhZ But the memory interface is 256bit well.

Looking at the performance, one can safely say that this card is a monster single GPU. Can grind all games and applications FullHD without any problem. It ‘was born for this purpose and use it at lower resolutions of 1650 * 1050 would be a waste, in fact from the best in resolution 1900 * 1200pixel! Consumption is much lower than the Nvidia counterparts, because the card consumes only 27W at idle, while in full load reaches 188W. Responsible for AMD and ATI to be able to save us some power in this respect. Another positive note is the low noise and low temperatures of the card. Idle rarely feels, in fact the fan is running at 30%, while in full load rarely goes above 60% thereby remaining always very quiet and keeping the video card always at optimum temperatures (never above 75 °).

By testing performance, we see that the card gets along very well without any kind of difficulty with the current games and probably also with future games. In fact, the average number of fps is very reassuring about that.
- Crysis in DirectX 10, and high quality anisotropic filtering to 16x is an average of 55 FPS at a resolution of 1920 * 1200.

- Devil May Cry as maximum, with antialiasing at 4X and DirectX 10 has an average of 110 FPS at a resolution of 1900 * 1200.
-Tom Clancy’s HAWX, a maximum of details with antialiasing at 4X and DirectX 10 enables us to get 80 FPS at 1900 * 1200.

- With Far Cry 2, high-quality antialiasing at 4X and DirectX10 travel around 75 FPS at 1900 * 1200.
- With Grid, as maximum and antialiasing at 4X, is an average of 150 FPS at resolution 1900 * 1200.

With Aliens Vs Predator-2010, DirectX 11 to 1900 * 1200, with detailed highs and anisotropic filtering to 16x is an average of 50 FPS.
Note the very high resolution at which the tests were performed. As you can see the board is perfectly safely FullHD and able to run all the current titles in highest details and filters without any problem.
I conclude that the benefits seen, consumption always good and quiet, the price of EUR 350 is more than justified. Hopefully if you do not want to spend all this money you can bet on the HD5850 (270 euros) that will enable us to always play well in FullHD but waiving certain filters and with knowledge that will be a bit less longevity than the HD5870 in terms prestazionevole .

ATI Radeon HD 5870 Graphics VIDEO REVIEW

ATI Radeon HD 5870 Graphics USER REVIEW

Insanely fast, overclocking “out-of-the-box” is ok, goes to 900/1250.
After applying ASUS Bios and using MSI Afterburner, can get the GPU all the way to 1100-1200Mhz stable (can go to 1400 but good luck trying it), however no luck with the memory going over 1250.

Pros:

• Fastest video card on the market, can run anything with full details on my 24″ at 1920×1200
• Can use an MCW-60 to watercool it (uses standard Ati holes/plate) and go to even higher clocks with low noise
• Looks great on the case, a big card with a nice design on it (other brands place a girl/axe/other stuff on the side of the card that IMO looks ugly)
• Ati has the only DX11 cards on the market right now
• Display Port finally!
• Eyefinity with 3 monitors

Cons:

• A bit more overclockability from the memory will be nice.
• Over 1000Mhz the standard hsf can become noisy
• Eyefinity with 3 monitors (a con since it makes me think to buy 2 more monitors…

The sequence of launches implemented by AMD over the past 2 months is somewhat impressive. On 23 September was debut day for the two Radeon HD 5870 and Radeon HD 5850, proposed top of the range with a single GPU architecture with support for DirectX 11 API. On 13 October it was the turn of the solutions Radeon HD 5770 and Radeon HD 5750 cards, which include the architectural features of the two proposals Radeon HD 5800 with appropriate simplifications leading to a contained cost.

Thursday 18 November, when the card is the Radeon HD 5970, proposed new summit in the panorama of ATI graphics cards supporting DirectX 11, which incorporates an approach popularized by AMD with the symbol X2: The GPU on the same pair two PCB, exploiting the benefits of this technology CrossFireX. The symbol X2 disappears in this new generation of X2 dual GPU cards, better known by the codename of Hemlock, in favor of a new series of numbers, the 5900, which helps to better compare the new proposal with the other solutions already in 5000 family market.

The range of solutions for ATI DirectX 11 is not complete: in the first quarter of 2010 AMD will also present the known solutions with the code names of Redwood and Cedar, position in the market segment under the £ 60 price and thus aimed at be marketed with the highest overall volumes. We shall now proceed to outline what are the technical features of the new Radeon HD 5970, comparing it with other solutions, ATI Radeon 5000 series up to now available:

The ATI Radeon HD 5970 uses two RV870 GPUs, each with 1600 stream processors: it is then taken to the same type cards Radeon HD 5870. The frequencies of GPU and video memory are those of the proposed Radeon HD 5850, respectively at 725 MHz and 4000 MHz: the direct consequence is that the Radeon HD 5970 is not quite the same as two Radeon HD 5870 side by side, as if the architecture in terms of stream processors is the same clock frequencies are lower end. The same way this card is not equivalent to two Radeon HD 5850 in CrossFireX configuration, since the number of stream processors is higher.

This choice was made to limit the overall consumption of the sheet as we see from the table below AMD reports a value of only 42 watts of consumption for the Radeon HD 5970 at idle, a figure that rises up to 294 watts when brought to full load. A value of this type justifies the presence of a 6-pin power connector supported by a 8-pin, against the design in 2 6-pin connectors adopted by AMD for the Radeon HD 5850 and Radeon HD 5870.

The two communicate using GPU CrossFireX technology, as well as already seen for the previous dual GPU solutions from ATI. Between the two RV870 chip is positioned switch developed by PLX PCI Express: This is a second-generation, and then developed based on the specific PCI Express 2.1. The remaining specifications are unchanged: AMD has doubled all components, including the amount of video memory that is equal to 2 Gbytes. Considering the dual GPU architecture is well to consider that the total memory is always to be divided between two chips, and consequently is the threshold of 1 Gbyte what is the real bottleneck to higher resolutions and in combination with filters.

To be able to mount two GPUs on the same PCB and ensure the substantial processing power in this card is capable AMD is down due to an obvious compromise in terms of overall length, following in this trend already seen with the debut of the solution ATI Radeon HD 5870. We will see how this may represent a limitation for installation in most of the chassis.

Longer, therefore more powerful?

With the family card ATI Radeon HD 5000 introduced a new type of cooling system: the board is completely covered with a plastic shell that conceals the block heat dissipation. The air is moved by a fan integrated with a path that leads to cool the radiator in contact with the GPU and expel it in part to the outside, partly back into the chassis. This solution was not adopted by the Radeon HD 5750, is particularly efficient as we saw during the analysis of the other Radeon HD 5000 series cards.  Radeon HD 5970 solution with this approach is maintained, however, setting new records in terms of footprint.

The card is easily distinguishable from model Radeon HD 5870 just looking at the back: stand out are two openings at the two GPUs, with an aluminum plate that completely covers the back protecting the components mounted here.

we compared the Radeon HD 5000 series cards currently available on the market, so as to better assess the overall footprint of the proposed new dual GPU. The overall length of this card, excluding the mounting plate and then providing guidance for the calculation within the chassis footprint, is equal to 30.5 cm, slightly less than 3 cm above that of the Radeon HD solution 5870. Riproponiamo lo schema completo delle differenti proposte presenti sul mercato di ATI e NVIDIA: Present anew the complete pattern of the different proposals on the market from ATI and NVIDIA:

•     ATI Radeon HD 5970: 30,5cm ATI Radeon HD 5970: 30.5 cm
•     ATI Radeon HD 5870: 27,7cm ATI Radeon HD 5870: 27.7 cm
•     NVIDIA GeForce GTX 285: 26,7cm NVIDIA GeForce GTX 285: 26.7 cm
•     NVIDIA GeForce GTX 295: 26,7cm NVIDIA GeForce GTX 295: 26.7 cm
•     ATI Radeon HD 4870 X2: 26,7cm ATI Radeon HD 4870 X2: 26.7 cm
•     ATI Radeon HD 5850: 24cm ATI Radeon HD 5850: 24cm
•     ATI Radeon HD 4890: 24cm ATI Radeon HD 4890: 24cm
•     ATI Radeon HD 5770: 22cm ATI Radeon HD 5770: 22cm
•     ATI Radeon HD 5750: 20cm ATI Radeon HD 5750: 20cm

The power supply is ensured by the presence of a 6-pin PCI Express connector, flanked by an 8-pin, this is the same type of design followed by the ATI Radeon HD 4870X2 as well as for the proposal by NVIDIA GeForce GTX 295. The same as shown with the Radeon HD 5870, we see how the power connectors are positioned upward so as not to further contribute to increasing the horizontal footprint of the card within the chassis.

The rear panel connections of the card differ somewhat from those of the two solutions Radeon HD 5800: there are two DVI connectors and a Mini DisplayPort connector, half of the bracket is occupied by the grid for evacuation of hot air. Radeon HD 5800 cards in the connectors are two DVI, one HDMI DisplayPort and one with a grid of wide hot air evacuation of half the Radeon HD 5890. Compatibility with the technology Eyefinity, like other Radeon HD 5000 series so far presented, is assured.

2 GPUs on single PCB

Let’s look at what are the technical specifications of the Radeon HD 5970 in terms of layout of components and cooling system used. GPU and video memory are the same components for the solutions adopted Radeon HD 5870, albeit with different operating frequencies by default that we specified: any 1600 integrated GPU stream processors while the video memory is based on GDDR5 chip capable of a theoretical maximum clock frequency of 5.000 MHz

Removing the heat sink we highlight the two RV870 GPUs, separated by bridges PCI Express 2.1, which constitutes the link between them and with the PCI Express 16x.  There is no technology SidePort, implemented in hardware in the Radeon HD 4870 X2 but in fact never enabled by driver side, AMD has justified this choice for the Radeon HD 5970 with significant bandwidth made available by the new PCI Express 2.1 bridge PLX strangely silkscreened AMD, more than enough for transmission of data to and from the two GPUs.

Analyzing the PCB height of the two power connectors are known as the 6-pin is actually mounted on a predisposition for 8-pin connector. A design of this kind leaves suggest for the future versions of custom Radeon HD 5970, with clock frequencies higher than the default is matched with two PCI Express power connectors 8-pin so as to ensure proper nutrition.

The power circuitry sees the use of Volterra voltage regulators, fully digital, programmable, integrated on the PCB there is also a system for monitoring real-time power, essential to ensure proper use of the circuitry of power especially when the tab is pushed at frequencies higher than the default. To close the use of pure ceramic capacitors, capable of balancing small size with high robustness.

The cooling system is borrowed from what was developed by ATI for the Radeon series 5800. We find a single fan that sucks air from inside the chassis blowing out most of the homes and partly because of some back into the racks at the top of the card.  The two GPUs are positioned in direct contact with the radiator in copper, while the GDDR5 memory modules are made of aluminum plates is at the top of the PCB as in the lower.

The heat sink uses the Vapor Chamber technology to transfer heat from the two GPUs to the outside and AMD certify this solution for heat to dissipate up to 400 watts, so far superior to what is consumed by the adapter even when fully loaded. This certification suggests that the same cooling system partners in the American manufacturer will increase the clock frequencies by default, of course, the balancing circuitry to supply new demands.

The heat generated during operation, together with the absorption of the board, have undoubtedly represented serious obstacles in developing this solution: It is not surprising to see how the two GPUs have been set at clock speeds lower than the Radeon HD 5870 solution, with an appropriate selection of the chips in search of those who are in possession of the lowest levels of leakage. This technical choice, combined with the sizing of the cooling system, we can expect good margins overcloccabilità for this solution: just look like the rest of GDDR5 modules used are certified for a maximum clock frequency of 5 GHz, compared with a default equal to 4 GHz for this card. Precisely for this reason, AMD has chosen not to limit the maximum clock speeds selectable by the driver Catalyst Overdrive panel, leaving scope for more action up to 1,000 MHz for the GPU and 1,500 MHz (6,000 MHz effective) for video memory.

Test Configuration

To analyze the performance of graphics cards in the test we used a platform based on Intel Core i7 965 Extreme, with the default clock frequency of 3.2 GHz and Turbo Mode technology enabled. The actual clock frequency is therefore equal to 3.33 GHz when the processor is used at full load, because the technology enables a Turbo Mode Frequency Multiplier more when 2 or more cores are used simultaneously.

Further details of the components used for testing:

•     Processor: Intel Core i7 965 Extreme, clock 3.2 GHz Turbo Mode technology active;
•     RAM: 3×2 Gbytes Corsair TR3X6G1600C8D; clock frequency equal to 1600 MHz with timings of 8-8-8-24;
•     Hard drive: Western Digital WD7500AAKS, 750 Gbytes SATA 7200 rpm;
•     Motherboard: MSI Eclipse SLI X58 Intel chipset;
•     OS: Windows Vista Ultimate 64bit with Service Pack 1 and all the latest fixes issued by Microsoft;
•     NVIDIA video driver: Forceware 191.00 beta
•     Driver ATI Radeon HD 4870 X2
•     Driver ATI Radeon HD 5870-5850: Catalyst 8.66 RC6
•     Driver ATI Radeon HD 5770-5750: RC6 Catalyst 8.66 beta 2

These titles included in this comparison, with the different configurations used.

    * Crysis Warhead
      It was used the benchmarking tool developed by Hocbench, the map is the airfield, with 16x anisotropic filtering enabled by Benchmark and 4x anti aliasing. The tests were performed with high quality settings, enable the DirectX 10 API.
    * Call of Duty 5
      Benchmark using the tool Fraps, 4x anti-aliasing enabled and all set at maximum quality settings panel configuration of the game.
    *  World in Conflict
      Benchmark integrated into the game, done selecting the setting very high quality with anti aliasing 4x and anisotropic filtering 16x.
    * The Last Remnant Benchmark
      Benchmarking tool automatic settings do not allow a specific quality that is not the change in video resolution.
    * Devil May Cry 4
      Benchmarking tool runs on the demo version of the game quality settings selected were those of the highest quality, with DirectX 10 API and 4x anti aliasing. It was rated the number 2 of the benchmark scene.
    * Far Cry 2
      Studies with DirectX 10, enabling high quality settings with 4x AA and setting very high quality with AA disabled.
    * Tom Clancy’s HAWX
      Benchmark integrated into the game, used in the demo version, done by highlighting all the quality settings on High except for ambient occlusion low. The tests were run under DirectX 10 API with 4x anti-aliasing enabled, for ATI video cards has also performed a test with DirectX 10.1 and anti aliasing 4x.
    * Grid
      A driving simulator developed for DirectX 10 graphics features a challenging and uniquely rich in detail. Given the absence of a benchmark integrated, in this case, we used Fraps to record frame rate.
    * Batman: Arkham Asylum
      Batman: Arkham Asylum is a title that made people talk more recently: developed by Eidos, the game is able to support PhysX technology at NVIDIA. Failure to set the filter anti-aliasing for ATI graphics cards inside the game requires the use of driver Catalyst to force AA 4x.

Consumption and noise

Measurements for the consumption of the cards have been registered with the instrument Watts Up PRO. The ability to record consumption at regular intervals upstream of the power supply and have that data immediately available in digital format has allowed us to create a chart on the energy demand of the card during scenario testing. To load significantly graphics cards you have performed a run of HAWX at 2560×1600. Following are the graphs, while there have been no specific task to occupy the processor in addition of course to the game 3D.

The charts were divided into two categories for ease of reading, comparing 4 models of the series Radeon HD 5000 and many proposals from the family of NVIDIA GeForce GTX 200. Analyzing the behavior of the Radeon HD you can see how, at idle, fuel consumption is nearly true: only the proposal developed with two Radeon HD 5970 GPUs on the same PCB beckons maximum values above 150 watts for the system. The absorption peaks at full load are directly proportional to those in single-GPU solutions but obviously higher, with a maximum value close to 350 watts.

The situation is different but going to watch the behavior of NVIDIA cards. The execution of a game like HAWX shows how the use of the SLI is highly fluctuating, varying according to the stage where you are. For this reason, the evolution of dark green line, the GeForce GTX 295, shows a continuous alternation of peaks. The idle power clearly show the superiority of the new generation of graphics cards developed by ATI and the goodness of the energy optimization that have been implemented. Following a summary about the minimum and maximum consumption recorded on each card.

The Radeon HD 5970 keeps overall value laden peak lower than the NVIDIA GeForce GTX 295, with an idle power far more content for the entire system with respect to the proposed dual GPU rival.

During this test we had, again, all values of the cards in noise test: for this reason, the new values may be different from those proposed in previous tests. The solution ATI Radeon HD 5970, for the enthusiast end of the market, despite facing a high amount of heat generated during operation is able to maintain an operating noise is not excessively high, although higher than the other proposals discussed. We also included a survey of operating noise, bringing the fan to maximum speed: ATI Radeon solutions are those that generate noise in this case higher, with a measurement of about 76 decibels measured at 10 cm distance: with this approach or results in an extremely effective cooling but also the inability to stay close to the card without significant disturbance. In practice, the fan does not ever close to this threshold of noise, are more aligned with the full load measurement in the chart.

Overclocking and operating temperatures

One of the things that AMD has stressed during the development of new video card for high-end market was overclocking. As we have stressed during the analysis of the structure of the graphics card, Radeon HD 5970 has been developed to be able to dissipate up to 400 watts. Analyzing the technical summary is also possible to see how, during the development of Radeon HD 5970, ATI has significantly reduced the frequency of operation of the GPU, using the Radeon HD 5850: not very restrictive, barring, you can use ATI Overdrive panel Catalyst Control to increase the working frequencies of Radeon HD 5970 up to a theoretical maximum of 1,000 MHz and 6,000 MHz for the GPU for video memory. Overclocking tests were then performed without special tools, but only through the use of ATI Overdrive, inside the control panel of the Catalyst drivers.

The first step was to set the two GPUs at the same frequency of operation of Radeon HD 5870: reaching the 850MHz was not a particular problem. To avoid encountering any excessive overheating of the board, we decided to set at 100% the speed of the fan, which corresponds to a rotation of 4,500 rpm . The operating temperature has remained stable below 54 °. In the next steps we have instead tried to bring the card up to 900MHz, but without success.

The threshold was found at 860MHz overclock over which we were unable to maintain stable platform: the impossibility of going to change the voltage was the real limit: to report the goodness of the system of heat dissipation in handle without major problems throughout the hot air produced by the two GPUs under stress. As for video memory behavior does not differ from that of the Radeon HD 5870: the chips are certified for a maximum frequency of 5,000 MHz, which is pretty easy reach the threshold above which it becomes difficult to be able to maintain stable operation.

Following the chart on the temperature with fan set to automatic:

 
The graph shows the behavior of the card during a session HAWX: the speed of rotation of the fan was set to automatic and operating frequencies are those references. Coinciding with the workload on the two GPU (the green line in the graph) the temperature continues to rise, until, after 4 minutes to 80 °. The temperature, certainly not low, forcing users who want to try to bring this card out of standard operating frequencies, to increase the speed of rotation of the fan. After about 45 seconds over the testing session, the board has fallen below 70 °, returning close to the temperature recorded at idle.

Considerations

If the ATI Radeon HD 5870 has been since the debut a reference point between the proposed single-GPU available on the market, the same can be said at the launch of Radeon HD 5970. AMD confirms the position of advantage over NVIDIA, this new card offering with a landmark performance. NVIDIA does not really have alternatives available: everything is back to the first quarter of 2010, during which the first solutions based on the architecture of the GeForce Fermi debut on the market. At present, make estimates about the capacity of these solutions is premature and we think pretty useless, not having the exact product is evident at the time, so it will be for at least the next 3 months, AMD’s dominance in the segment of video cards by mid-on.

The new board implements an effective cooling system, like the other proposals in the series Radeon HD 5800. The construction complexity has led to an overall length that sets new record: we did not test with chassis present in the office but there is no doubt that in many houses on the market a card of this type can be installed with great difficulty, if not be too long.

Direct performance comparison between the Radeon HD 5970 and Radeon HD 5870, Radeon HD 4870 X2 and GeForce GTX 295 shows a clear potential advantage for the newcomer, even more evident with increasing resolution up to 2560×1600 pixels. Flipping through our tests have the advantage of the new proposal is variable depending on title and resolution, but the synthesis of the various plots is very clear: this card is as fast is temporarily unavailable.

DThere are two implications of this: the price is anything but popular, and very limited availability. To influence up the price and the availability of the product, whereas the already reduced market position but is negatively affected by the shortage currently affecting all cards since the debut of the Radeon HD 5800. ATo justify this situation the well-known problems with the TSMC 40-nanometer manufacturing process, AMD may hinder an industry that sees it, at least at this moment, as the undisputed leader in technology and performance.
