Introduction and Specifications
AMD's "Sweet Spot" GPU strategy over the last few years has been fairly predictable. Instead of producing the biggest, most powerful GPU possible--yields be damned--the company sets out to produce a relatively high-end GPU, using a cutting edge fabrication process, that hits a proverbial sweet spot between cost and performance. Then derivatives, and even multiples, of that GPU are used to flesh out a top-to-bottom line-up of graphics cards, that hit a broad range of price points.

It began with the RV670, which powered the single-GPU based Radeon HD 3870 and dual-GPU Radeon HD 3870 X2--hence the X2. Then came the RV770, which powered the Radeon HD 4870 and eventually the Radeon HD 4870 X2. The strategy has obviously paid off, as AMD is once again a price/performance leader in the GPU space, after some not-so-great performances like the R600, better known as the Radeon HD 2900 XT.  Knowing their strategy, it should almost come as no surprise that the graphics card we'll be showing you today, the Radeon HD 5970, has come to fruition. Although it doesn't follow the same naming convention as AMD's previous dual-GPU powered cards, the Radeon HD 5970 is nonetheless powered by a pair of ATI "Cypress" Radeon HD 5800 series GPUs, linked together on a single PCB by a PCI Express bridge, very much like previous X2 iterations.

Considering the fact that the Radeon HD 5870 is undeniably the fastest single-GPU powered graphics card currently on the market, this dual-GPU powered Radeon HD 5970 should offer performance that completely outclasses any other single graphics card on the market currently. In addition to killer performance, the Radeon HD 5970 also boasts all of the same features of the Radeon HD 5800 series, like full DirectX 11 support, ATI Eyefinity support, top-notch image quality and power efficiency.

We've got a Radeon HD 5970 in house, in full retail trim, courtesy of HIS that we've run through and array of benchmark tests. Read on to see how AMD's new flagship fares in light of competing single and dual-GPU powered solutions...

AMD's "Sweet Spot" GPU Strategy

AMD's release schedule with their latest barrage of DirectX 11 capable GPUs is outlined on the slide above. Of course, a lot of groundwork had to be laid over the years before the company could produce this line-up of products. As the above list of specifications and features show, the new Radeon HD 5970 is quite advanced in comparison to other current GPU products. But the chip does leverage technologies already implemented in previously released GPUs, so it's not all new.  As such, we'd recommend perusing some recent HotHardware articles to brush up on a few of the technologies and features employed by the new Radeon HD 5970...

The articles listed above cover many of the features available with the Radeon HD 5970, like CrossFire, the UVD 2 video engine, Catalyst Control Center, PowerPlay, GDDR5 memory, and more. There are, however, a lot of brand new things that were introduced with the Radeon 5800 series that we that we detailed in our Radeon HD 5870 coverage, so that article at the very least is a must-read companion to this piece.

The ATI Radeon HD 5970

So, what differentiates the new Radeon HD 5970 from its Radeon HD 5800 series counterparts? Mainly it's the two Radeon HD 5800 series GPUs powering the card, but the comparison chart below does a good job of explaining what that means in terms of features and performance.

As you can see, the Radeon HD 5970 offers roughly double the performance of a Radeon HD 5850. What you'll notice, however, is that that 5970 is somewhat of a mix between the 5850 and 5870. All of the stream processors (1600) in each GPU are enabled in the Radeon HD 5970, hence it has double the total number of the Radeon HD 5870 (3200). The Radeon HD 5970's clock speeds, however, are in-line with the Radeon HD 5850. We're told it's the mixing of 5800 series specifications that resulted in the new naming convention for the Radeon HD 5970--it's not quite a 5850 X2 or a 5870 X2, so in an attempt to avoid confusion, AMD gave the card a name that should convey the message that the 5970 is the highest performer of the three.

With its GPUs, the Radeon HD 5970 offers roughly double the performance of a Radeon HD 5850, save for its peak fillrate which is somewhat higher. Max memory bandwidth from the card's 2GB of GDDR5 memory is 256GB/s, but keep in mind that's 128GB/s per GPU.

The 5970's maximum board power is rated for 294W, which somewhat explains why the 5970's clocks aren't higher. Had AMD pushed those stock frequencies any higher, max board power would be well north of 300 watts, which could post a problem to potential upgraders with power supplies that aren't up to snuff.

   

   
ATI Radeon HD 5970 Architectural Details

The Radeon HD 5970 architecture is much like previous X2 cards. Each of the card's GPUs are linked together on a single PCB, via a PLX PCI Express 2.1 Gen 2 bridge. The setup is essentially "CrossFire on a card". The dual-GPU configuration gives the Radeon HD 5970 peak compute performance of over 4.6 TeraFLOPs with 116GTexels/s of texture fillrate.

More when into the design of the Radeon HD 5970 than slapping a pair of GPUs on a single PCB. To ensure significant overclocking headroom, AMD used 5.0 Gpbs (1250MHz) GDDR5 memory on the 5970, despite the 1000MHz default clock. In addition, the cards feature digital programmable Volterra Regulators, pure ceramic Japanese caps, and real-time power monitoring circuitry. The GPUs on the Radeon HD 5970 are also screen high-speed / low-leakage ASICs, and the cooling solution is capable of handling far more heat than is put off in the stock configuration. 

  

  
AMD ATI Radeon HD 5970 Reference Card

The Radeon HD 5970 card itself is 12" long and features a black fan shroud that encases the entire PCB, that looks similar to the 5870. 12" is HUGE for a graphics card, so take note of its size. We had to remove the hard drive cage in our test machine to accommodate this beast. The card's cooler has a barrel fan that draws air into the shroud, where it is forced through the heatsink and partially exhausted from the system through vents in the card's mounting plate. Two more small vent at the back of the card also direct some air to be vented within the system. Overall, the cooling solution is much like the one used on the Radeon HD 5870, but it features a single, large vapor chamber and is capable of dissipating up to 400 watts.

  

  
AMD ATI Radeon HD 5970 Reference Card

The Radeon HD 5970 sports a GPU clock of 725MHz with a memory clock speed of 1 GHz (4Gbps effective). According to AMD, maximum board power is 294 Watts, up slightly from the previous generation dual-GPU powered 4870 X2, but idle board power is only 42 Watts. The low idle power comes by way of aggressive clock gating and voltage reductions when the card is not under a significant workload. Due to the relatively high peak power though, 6-pin and 8-pin supplemental power connectors are required.

The outputs on the Radeon HD 5970 consist of dual, dual-link DVI outputs and a DisplayPort output. With this output configuration, connecting the card to an HDMI input requires the use of a DVI-to-HDMI dongle, and three screen Eyefinity configurations are possible. We should also note, that beginning with the 5970, Eyefinity will support multi-GPU scaling with certain game titles. Once the kinks are worked out, AMD plans to migrate Eyefinity support to 5800 series CrossFire configurations as well.

Transparent
HIS Radeon HD 5970

The first retail-ready Radeon HD 5970 card to hit the HotHardware labs came by way of HIS. Although availability of Radeon HD 5800 series GPUs has been scarce for a few weeks, we're told this card (and 5970s from many other AMD board partners) will be available immediately. And inventory on other 5800 series cards should be ramping back up soon too.

  

   
HIS Radeon HD 5970 Card

The HIS Radeon HD 5970 is essentially identical to the reference card pictured on the previous page, save for a large decal affixed to the front side of the card's fan shroud. The fan is the same, as is the output configuration, backplate, 2GB of GDDR5, power requirements, frequencies, etc.

  

  
HIS Radeon HD 5970 Accessory Bundle

HIS does, however, differentiate their Radeon HD 5970 with a unique accessory bundle. In addition to the card itself, included with the HIS Radeon HD 5970 is a multi-language quick installation guide, am HIS case badge, a driver CD, a CrossFire bridge connector, dual-Molex to 6-pin and 8-pin power adapters, DVI to VGA and HDMI dongles, a mini-DisplayPort to DisplayPort adapter, a coupon for the upcoming DX11-racing sim Dirt 2, and a cool multi-purpose tool with screwdrivers and a level.

The most interesting part of the HID Radeon HD 5970's bundle, however, was the included iClear card. According to HIS, the iClear card can "reduce the noise distortion generated from the high end graphics card or TV tuner cards". What the means to end users is anything but clear, however. We tested the HIS Radeon HD 5970 with and without the iClear card installed and didn't see any visual quality differences, and didn't experience any changes in stability or overclockability.

We should also note that this is the card we used throughout the performance testing laid out for you on the pages ahead.

Test Setup and 3DMark Vantage

HOW WE CONFIGURED THE TEST SYSTEM: We tested the graphics cards in this article on an Gigabyte GA-EX58-UD5 motherboard powered by a Core i7 965 quad-core processor and 6GB of OCZ DDR3 RAM. The first thing we did when configuring the test system was enter the system BIOS and set all values to their "optimized" or "high performance" default settings. Then we manually configured the memory timings and disabled any integrated peripherals that wouldn't be put to use. The hard drive was then formatted, and Windows 7 Ultimate x64 was installed. When the installation was complete we fully updated the OS and installed the latest hotfixes, along with the necessary drivers and applications.

Futuremark 3DMark Vantage
Synthetic DirectX Gaming


3DMark Vantage

The latest version of Futuremark's synthetic 3D gaming benchmark, 3DMark Vantage, is specifically bound to Windows Vista-based systems because it uses some advanced visual technologies that are only available with DirectX 10, which y isn't available on previous versions of Windows.  3DMark Vantage isn't simply a port of 3DMark06 to DirectX 10 though.  With this latest version of the benchmark, Futuremark has incorporated two new graphics tests, two new CPU tests, several new feature tests, in addition to support for the latest PC hardware.  We tested the graphics cards here with 3DMark Vantage's Extreme preset option, which uses a resolution of 1920x1200 with 4x anti-aliasing and 16x anisotropic filtering.




Looking at the Radeon HD 5970's performance in 3DMark Vantage, two things become apparent. First, the card offers phenomenal performance that dwarves any of the single-GPU powered cards. Second, the Radeon HD 5970's performance falls right in-line with expectations. Considering the card has the same number of stream processors as a Radeon HD 5870 CrossFire configuration, but the same clocks as a Radeon HD 5850, we'd expect performance to fall somewhere between the two configurations. And that's exactly what happens. The Radeon HD 5970 finishes ahead of the Radeon HD 5850 CrossFire setup, but behind the higher-clocked 5870s.

Enemy Territory: Quake Wars

Enemy Territory: Quake Wars
OpenGL Gaming Performance


Enemy Territory:
Quake Wars

Enemy Territory: Quake Wars is Based on a radically enhanced version of id's Doom 3 engine and viewed by many as Battlefield 2 meets the Strogg, and then some.  In fact, we'd venture to say that id took EA's team-based warfare genre up a notch or two.  ET: Quake Wars also marks the introduction of John Carmack's "Megatexture" technology that employs large environment and terrain textures that cover vast areas of maps without the need to repeat and tile many smaller textures.  The beauty of megatexture technology is that each unit only takes up a maximum of 8MB of frame buffer memory.  Add to that HDR-like bloom lighting and leading edge shadowing effects and Enemy Territory: Quake Wars looks great, plays well and works high end graphics cards vigorously.  The game was tested with all of its in-game options set to their maximum values with soft particles enabled in addition to 4x anti-aliasing and 16x anisotropic filtering.



Our custom Enemy Territory: Quake Wars benchmark has the Radeon HD 5970 well ahead of any of the singe-GPU powered cards, but trailing the dual-5800 series CrossFire configurations. This test is more memory bandwidth bound than shader bound, and as such the Radeon HD 5970's additional stream processors don't help it to pull ahead of the similarly clocked Radeon HD 5850 cards running in CrossFire mode. Instead, the dual-Radeon HD 5850 CrossFire configuration finishes just a bit ahead of the 5970 and the Radeon HD 5870's take the top spot.

Crysis v1.21

Crysis v1.21
DirectX 10 Gaming Performance


Crysis

If you're at all into enthusiast computing, the highly anticipated single player, FPS smash-hit Crysis, should require no introduction. Crytek's game engine produces some stunning visuals that are easily the most impressive real-time 3D renderings we've seen on the PC to date.  The engine employs some of the latest techniques in 3D rendering like Parallax Occlusion Mapping, Subsurface Scattering, Motion Blur and Depth-of-Field effects, as well as some of the most impressive use of Shader technology we've seen yet.  In short, for those of you that want to skip the technical jib-jab, Crysis is a beast of a game.  We ran the full game patched to v1.21 with all of its visual options set to 'Very High' to put a significant load on the graphics cards being tested  A custom demo recorded on the Ice level was used throughout testing.

 


Our custom Crysis benchmark puts a significant strain on all of the cards we tested, as is evident by the relatively low framerates. Here, the Radeon HD 5970 once again crushes all of the single-GPU powered cards and smokes the GeForce GTX 295. The 5970, however, finishes in a dead heat with the Radeon HD 5850 CrossFire configuration and trails the Radeon HD 5870 CrossFire setup by a sizable margin, somewhere in the neighborhood of 18%.

FarCry 2

FarCry 2
DirectX Gaming Performance


FarCry 2

Like the original, FarCry 2 is one of the more visually impressive games to be released on the PC to date.  Courtesy of the Dunia game engine developed by Ubisoft, FarCry 2's game-play is enhanced by advanced environment physics, destructible terrain, high resolution textures, complex shaders, realistic dynamic lighting, and motion-captured animations.  We benchmarked the graphics cards in this article with a fully patched version of FarCry 2, using one of the built-in demo runs recorded in the "Ranch" map.  The test results shown here were run at various resolutions with 4X AA enabled.

 


Although the framerates are somewhat higher, our results from the FarCry 2 benchmark look much like those from Crysis. The Radeon HD 5970 simply dominates all of the single-GPU powered cards and the dual-GPU powered GeForce GTX 295, but essentially ties the Radeon HD 5850 CrossFire setup. The Radeon HD 5870 cards running in CrossFire mode, once again, take the lead.

Left 4 Dead

Left 4 Dead
DirectX Gaming Performance


Left 4 Dead

Left 4 Dead is a co-operative, survival horror, first-person shooter that was developed by Turtle Rock Studios, which was purchased by Valve part-way into development. Like Half Life 2, the game uses the Source engine, however, the visual in L4D are far superior to anything seen in the Half Life universe to date. The game pits four Survivors of an apocalyptic pandemic against hordes of aggressive zombies. We tested the game at resolutions of 1,920 x 1,200 and 2,560 x 1,600 with 4x anti-aliasing and 16x anisotropic filtering enabled and all in game graphical options set to their maximum values.

 

Left 4 Dead is mostly CPU bound with the dual-GPU powered Radeon 5000 series configurations and the additional overhead introduced by CrossFire results in slightly lower framerates at 1920x1200. All of the cards we tested put up good numbers here, however. Even there there is a clear advantage for the dual-GPU powered configurations at the higher resolutions here, gamers would be hard pressed to notice the performance differences in this game. Time to move on to Left 4 Dead 2. Comes out tonight!

Tom Clancy's H.A.W.X.

Tom Clancy's H.A.W.X. is an aerial warfare video game that takes place during the time of Tom Clancy's Ghost Recon Advanced Warfighter.  Players have the opportunity to take the throttle of over 50 famous aircrafts in both solo and 4-player co-op missions, and take them over real world locations and cities in photo-realistic environments created with the best commercial satellite data provided by GeoEye.  We used the built-in performance test at two resolutions with all quality settings set to their highest values, using the DX10-based engine for the GeForce cards, and DX10.1 for the Radeons.

  


The results from the H.A.W.X. benchmark look much like those from Enemy Territory: Quake Wars a few pages back. Here, the Radeon HD 5970 has no trouble dispatching all of the single-GPU powered configurations and handily outpaces the dual-GPU powered GeForce GTX 295. However, the Radeon HD 5850 and 5870 CrossFire configurations take the top two spots.

Radeon HD 5970 Overclocking

AMD has stated that the Radoen HD 5970 is "unlocked" and well suited to overclocking. As such, we were curious to see how much frequency headroom the Radeon HD 5970 had left under its hood. So, for our next set of performance metrics, we spent some time overclocking the new Radeon HD 5970 using the Overdrive utility built into ATI's Catalyst drivers in addition to a simple over-volting utility AMD made available for testing.

Overclocking The Radeon HD 5970
Pedal To The Metal

 

The Radeon HD 5970's stock GPU and memory clock speeds are 725MHz and 1000MHz, respectively, at 1.05v (GPU) and 1.1v (memory). With a bump in voltage to 1.1625v for the GPU and 1.15v being supplied to the memory though, we were able to take those clocks up to 860MHz and 1.22GHz.

With clock speeds that high, the Radeon HD 5970 should be faster than a pair of Radeon HD 5870 cards running in CrossFire mode, and that's exactly what we observed. With the Radeon HD 5970 overclocked, we re-ran a couple of benchmarks at 1920x1200 and the card was able to pull ahead of the Radeon HD 5870 CrossFire setup.

We should note, that power consumption went way up for the Radeon HD 5970 while over-volted and overclocked. At stock settings, the card consumed 393 watts under load, but that number jumped to 460 watts with its frequencies and voltages tweaked.

Transparent
Power Consumption and Noise

Before bringing this article to a close, we'd like to cover a few final data points--namely power consumption and noise. Throughout all of our benchmarking and testing, we monitored how much power our test system was consuming using a power meter. Our goal was to give you all an idea as to how much power each configuration used while idling and while under a heavy workload. Please keep in mind that we were testing total system power consumption at the outlet here, not just the power being drawn by the graphics cards alone.

Total System Power Consumption
Tested at the Outlet

 


The Radeon HD 5970's power consumption characteristics are fairly good, despite the card's ultra-high performance. In our testing, the Radeon HD 5970 pulled slightly more power than the Radeon HD 5850 CrossFire configuration under both idle and load conditions. Idle power is relatively low in light of NVIDIA's current offerings, but expectedly higher than the other Radeon HD 5800 series cards.

While we're on the subject of power, we's also like to talk about noise for a bit. Despite the Radeon HD 5970's complexity and excellent performance the card's fan spun up far less than we anticipated, which resulted in a relatively quiet experience overall. While idling the Radeon HD 5970 is, for all intents and purposes, inaudible. Under load, the card's fan is audible, but we would not consider it noisy by any means and during testing it never spun up to top speed.

We should also point out that the Radeon HD 5970 also runs relatively cool. While idling, we witnessed GPU temperatures in the mid-50'C range. While under load, that number shot up into the mid-80'C range.

Our Summary and Conclusion

Performance Summary: Summarizing the ATI Radeon HD 5970's performance couldn't be any easier. The Radeon HD 5970 is simply the fastest, most powerful single graphics card available today. The Radeon HD 5970 offered better performance than every other graphics card we tested, regardless of the game or application. In comparison to other multi-GPU solutions, the Radeon HD 5970 falls in-line right about where you'd expect it to, considering its specifications.  It's about on par with, or slightly ahead of, a pair of Radeon HD 5850 cards in CrossFire, but behind a Radeon HD 5870 CrossFire configuration.

 

AMD deserves a heck of a lot of credit. Not only has the company launched no less than five DirectX 11-class graphics cards over the last two months, but they have set the performance bar at each of their respective price points. The new ATI Radeon HD 5970 is without question the single most powerful graphics cards we have tested to date.

Not only is the Radeon HD 5970 the undisputed performance leader, but it is also one of the most feature laden graphics cards currently on the market. With its dual Radeon HD 5800 series GPUs, the Radeon HD 5970 fully supports DX11 and ATI Eyefinity multi-display technology, and also sports the latest UVD engine, and has some of the best in-game image quality of any graphics card. On top of that, the card is highly overclockable, and despite being powered by a pair of the fastest GPUs out there, its power consumption characteristics aren't all that off the chart. Strictly speaking in terms of features and performance, the ATI Radeon HD 5970 currently has no rivals. Until you start pairing up multiple single-GPU powered cards, that is. 


AMD ATI Radeon HD 5970

About the only downside to the Radeon HD 5970 is cost. The first wave of Radeon HD 5970 cards due to hit etailers today carry a hefty $599 MSRP. In light of its performance and current prices for competing products, $599 is certainly justifiable for the Radeon HD 5970, but we'll miss the days of sub-$400 flagship graphics cards--thank you Radeon HD 5870.

Heading into the all important holiday season, it seems AMD's graphics division is in an excellent position. NVIDIA has yet to show its hand with regard to next-gen 3D gaming-oriented GPUs.  Currently, AMD's products at every price point from $150 on up to $600 are best-of-class contenders. Here's hoping AMD can make enough of them to satisfy demand and fully fuel development of their next-generation of products.
