The catch however is that what we don’t have is a level of clear domination when it comes to single-card solutions. AMD was shooting to beat the GTX 295 with the 5870, but in our benchmarks that’s not happening. The 295 and the 5870 are close, perhaps close enough that NVIDIA will need to reconsider their position, but it’s not enough to outright dethrone the GTX 295. NVIDIA still has the faster single-card solution, although the $100 price premium is well in excess of the <10% performance premium.

-From Our Radeon 5870 Review, On The GTX 295 vs. The 5870

Let’s get straight to the point, shall we? Today AMD is launching the 5970, their dual-GPU card that finishes building out AMD’s technical domination of the high-end market. With it AMD delivers the absolute victory over NVIDIA’s GTX 295 that the Radeon 5870 couldn’t quite achieve and at the same time sets the new high water mark for single-card performance.

This also marks the last AMD product introduction of the year. The rest of the Evergreen series, composing the sub-$100 low-end parts, will be launching next year.

The 5970 serves as the nowadays obligatory dual-GPU part. It is 2 Cypress dice mounted on a single, dual-slot video card. AMD clocks it at 725MHz core and 1GHz (4GHz effective) for the GDDR5 memory. The card comes equipped with 2GB of GDDR5, which is split between the two GPUs, giving it an effective memory capacity of 1GB. The card will be selling for $600, at least so long as vendors and retailers hold the line on MSRP.

In practice this makes the card something between a 5850 in Crossfire mode and a 5870 in Crossfire mode. The clocks are the same as the 5850, but here all 20 SIMD units are enabled. This is a 15% clockspeed difference between the 5970 and 5870CF, so officially the 5870CF will continue to be the faster setup. However as we’ll see in a bit, looking at the stock 5970 can be a bit deceiving.

This also brings up the matter of the name of the card. We asked AMD what happened to the X2 tag, and the answer is that they didn’t want to use it since the card was configured neither like a 5850 nor a 5870 – it was closer to a mythical 5860. So rather than call it an odd (or worse yet, wrong) name, AMD just gave it a new model number entirely. We suspect AMD wanted to be rid of the X2 name – their processors go up to X4 after all – but there you go as far as an official reason is concerned. It looks like special multi-GPU tags are now gone in both the NVIDIA and AMD camps.

Moving on, for power, the 5970 uses an 8pin and a 6pin power connector (although the 6pin sits on top of a spot silk-screened for anther 8pin). The TDP is 294W, bringing it in just under the 300W ATX limit. Idle power is 42W, thanks to AMD’s aggressive power optimizations present in the entire 5000 series.

As some of you may have noticed, in spite of the fact that this card is at least a pair of 5850s, it consumes less than the 320W (2x160W) such a setup would. In order to meet the 300W limit, AMD went and binned Cypress chips specifically for the 5970, in order to find chips that could operate at 725MHz at only 1.05v (the 5850 runs at 1.088v). Given the power creep coming from the 4800 series, binning for the best chips is the only way AMD could get a 300W card out.

AMD’s official guidance for this card is that the minimum requirements are a 650W power supply, and they recommend a 750W power supply. The recommended power supply will become more important later on when we talk about overclocking.

Finally, AMD is also launching Crossfire Eyefinity support with the 5970, and thus far only the 5970. Currently Eyefinity doesn’t work with Crossfire mode on any of AMDs cards due to driver limitations. The drivers that the 5970 will be shipping with enable Crossfire Eyefinity support on the 5970 for 22 games – currently AMD is using whitelisting and is enabling games on a case-by-case basis. Crossfire Eyefinity will make its way in to the mainstream Catalyst drivers and be enabled for other cards early next year.

ATI Radeon HD 5970 Review: Dual-GPU Graphics

ATI revealed its last generation Radeon 5000 graphics family last September, when we got the chance to review the ATI Radeon HD 5870, and what a treat that was.

In a few tests the single-GPU Radeon HD 5870 was able to outgun the mighty GeForce GTX 295, while in most it managed to match or improve upon the Radeon HD 4870 X2. As you are likely aware, both of these products carry dual GPUs, which bring a number of implications, not to mention bigger price tags.

Looking forward we knew Nvidia would have no immediate response to the new Radeons, while on the other hand ATI was not done unleashing its full series of products. Subsequently we looked at two more products that were meant to underperform the flagship HD 5870: the slightly cut down Radeon HD 5850 and the mainstream aimed HD 5770.

From left to right: Radeon HD 5770, HD 5850, HD 5870, and HD 5970.

But as we discussed in our preliminary Radeon 5870 review, on the horizon was also a follow-up to the Radeon HD 4870 X2, code-named «Hemlock XT», which in essence would put together a pair of Radeon HD 5870 GPUs on a single PCB.

Today AMD is officially unveiling the Hemlock as the new ATI Radeon HD 5970, hoping to expand its current dominance in single-GPU performance with the fastest single-slot graphics card on the market — a title that until today was reserved for Nvidia’s dual-GPU GeForce GTX 295.

The Radeon HD 5970 looks to be well suited for the job. The GPUs used in this card use exactly the same configuration found on the Radeon HD 5870, while core and memory frequencies match those of the Radeon HD 5850. This provides the HD 5970 with an unmatched memory bandwidth of 256GB/s.

All this horsepower will come at a hefty price, as AMD expects to charge as much as $600 for it. This is a bit hard to swallow, but all things considered it’s about where we expected it to stand among the rest of high-end graphics offerings.

Full exposure: A «naked» Radeon HD 5970 graphics card.

The $400 Radeon HD 5870 is still sold out virtually everywhere due to extreme shortages. The Radeon HD 5850 version still costs $300, meaning that a pair of them would cost the same amount as a single Radeon HD 5970, and we do not expect the performance to be nearly as good. On the other side of the equation, Nvidia’s top performer, the GeForce GTX 295 is selling for around $500.

As we see it, only extreme users looking for the best possible gaming experience — or the bragging rights attached to the label — will find the Radeon HD 5970 to make complete sense.

Knowing this is the 5970’s intended market, AMD has stamped a big «unlocked» label over the card in our press kit. Perhaps more marketing buzz than actual functionality, the Radeon HD 5970 allows you to jack core and memory frequencies as high as you like — or at least as high as they will go without compromising stability. This in itself is far from exciting news as there’s been software available to do just that for ages.

The most interesting part should come from the ability to adjust voltages and thus increase the card’s overclocking room, something we’ll be checking in detail next.

  Almost a year has passed since AMD (Advanced Micro Devices) officially introduced the graphics accelerator ATI Radeon HD 5970 , but to this day it remains the most productive. NVIDIA, having released its voracious monster on the GeForce GTX 480 chip, was unable to provide the market with its long-awaited two-chip version. The main problem here was the power consumption of such a solution and its exorbitant heat dissipation. AMD had the same difficulties with the release of the dual-chip video card ATI Radeon HD 5970, but the developers were able to get around them by lowering all the operating frequencies of the video card and selecting chips with a lower operating voltage. The ATI Radeon HD 5970 has the highest theoretical performance of 4.64 trillion floating point operations per second for a single video accelerator. This allowed the ATI Radeon HD 5970 dual-chip graphics adapter (codenamed Hemlock ) to be the most sought after among the most demanding gamers and PC enthusiasts.

  The AMD (ATI) comparison table of the main characteristics of the Radeon HD 58** series and the Radeon HD 5970 accelerator clearly demonstrates all the changes that Cypress chips had to undergo in order to use them in the Radeon HD 5970 accelerator.

  Board idle power consumption, W	42	27	27

  Reducing clock frequencies to the level of Radeon HD 5850 allowed to reduce the operating voltage both on the GPUs themselves and on the memory chips, which in turn reduced the total power consumption of the accelerator. Such an artificial reduction in performance was necessary to keep the maximum power consumption of the video card within the electromechanical specification of 300 W PCI-SIG. Raising the frequencies to the level of the Radeon HD 5870 (850 MHz core / 1200 MHz memory) would lead to the maximum power consumption of the board closer to 375 or even 400 watts.

  The reference ATI Radeon HD 5970 accelerator, as well as its analogue, which came to us for testing MSI R5970-P2D2G , uses a high-quality element base in the textolite filling, as well as an innovative two-slot active air cooling system. The design of the cooler assumes the presence of a rather large evaporation chamber, which is designed to effectively remove excess heat from the main «hot spots» of the product to a massive aluminum radiator. A standard size turbine blows over the aluminum fins with a PWM speed controlled fan.

  The use of specially selected graphics processors with low leakage currents made the video card even colder. Together with the installed special cooling system, this gives hope for power dissipation up to 400 watts. The lower frequencies and the use of higher stability chips should please overclocking enthusiasts, as they will be happy to make the graphics accelerator work at higher frequencies.

  We went a little deeper into the theoretical details announced by AMD for the ATI Radeon HD 59 reference accelerator.70, but real tests and a detailed review of the final product will tell us much more about the practical side of using this solution.

  The use of two AMD RV870 «Cypress» chips caused a number of noticeable changes in the graphics card specification in relation to the reference single-chip ATI Radeon HD 5870 solution. The doubling affected the number of stream pipelines , amount of installed memory and bandwidth of the memory bus. Operating frequencies have been reduced to 725 MHz for the GPU and to an effective 4000 MHz for the memory chips. The variety of connectors on the rear panel has been reduced to three, there are two DVI-I and one miniDisplayPort. Through the adapters included in the package, the user can connect the display via DisplayPort, HDMI and VGA interfaces. Such large-scale changes do not even allow us to predict the resulting performance, but we will be able to check it in the testing process.

  The video accelerator is delivered in a thick large box with an easy-to-carry plastic handle. A jet plane is depicted on the top of the package, probably as a symbol of the high performance of the video card. At the top you can see the company logo and icons of supported proprietary technologies ATI CrossFireX and ATI Eyefinity. Underlined at the bottom is the ATI Radeon HD 5970 accelerator model, the presence of 2 GB GDDR5 video memory, DirectX 11 support and the presence of a miniDisplayPort output. The box also indicates the presence in the delivery set of the proprietary MSI Afterburner utility for overclocking this accelerator.

  On the back of the box, you can see a detailed description of the features of the MSI Afterburner utility with screenshots of some of its windows. The advantages of the Military-class components used in this accelerator model are also described here:

  • Hi-c CAP (Highly-Conductive Capacitor) — high-conductivity tantalum capacitors provide more stable power supply to the graphics core.
  • SSC (Solid State Chock) — Closed chokes prevent coil vibration and improve heat dissipation from the coil, which improves conductivity for better overclocking stability.
  • Solid Cap (Solid Capacitor) — solid capacitors guarantee 10 years of trouble-free operation.

  MSI R5970-P2D2G delivery set is quite worthy:

  • One adapter from two peripheral power connectors to a 6-pin video card power connector;
  • One adapter from one 6-pin video power connector to an 8-pin video card power connector;
  • CrossFire Bridge;
  • CD with drivers and utilities;
  • Brief instructions for installing a video card;
  • DVI to HDMI adapter;
  • DVI to VGA adapter;
  • miniDisplayPort to DisplayPort adapter;

  The design of the video card is exactly the same as the rest of the «top» solutions of the 5th series of accelerators from AMD. It’s all because of the use in all reference video cards of a standard type of turbine and a uniform casing for it. This accelerator is among its brothers ATI Radeon HD 5970 is distinguished only by the MSI R5970 inscription on the top of the casing and the round MSI sticker on the cooling turbine fan itself.

  The ATI Radeon HD 5970 is even larger, by an inch (2.54 cm), compared to the already small ATI Radeon HD 5870. The MSI R5970-P2D2G measures 12.5 inches (31.75 cm). Such dimensions can create some problems when installing it in most conventional cases, but when purchasing such an accelerator, a real enthusiast simply has to take care of choosing a decent case.

  The reverse side of the accelerator, except for cut holes for the cooler mounting system, is completely hidden under a metal plate. It provides an increase in the rigidity of the entire structure and contributes to a more reliable fastening of the cooling system.

  Considering that this video card has two chips already connected in CrossFireX mode, the MSI R5970-P2D2G accelerator can be installed in CrossFireX mode only in pair with one similar model. This is possible thanks to a single connector for the CrossFire bridge, which is located on the top of the accelerator.

  Two chips and the controller connecting them required the installation of two additional power connectors. As a result, the predicted power supply of the video accelerator is provided through the PCI Express slot (75 W), one 6-pin additional power connector (another 75 W) and one eight-pin additional power connector (150 W). Recall that the reference version of the accelerator on the Radeon HD 5870 required the connection of two six-pin connectors.

  Due to the two-slot design of the cooling system, three display connectors (two DVI-I and miniDisplayPort) fit on the rear panel of the accelerator. There is also a large grille for removing hot air from the case.

  On the front side of the printed circuit board, a tandem of two GPUs and a switch chip that ensures their joint work is striking.

  The video accelerator is based on a pair of Cypress GPUs.

  The GPU frequency is 725 MHz. The RV870 chips themselves are made according to the 40 nm process technology, which leads to their relatively low power consumption. The number of unified shader processors each is 1600, texture units 80, and the number of ROPs 32.

  In the absence of load, the frequency of the chips decreases to 157 MHz, and the video memory slows down to 300 MHz (effective frequency 1200 MHz). At the same time, the supply voltage is reduced and the turbine speed is reduced, which provides a noticeable reduction in energy consumption and noise.

  Located between the GPU chips, the AMD8647-8850BC switch chip provides processor communication over 16 PCI Express 2.0 lanes. The switch is labeled as ATI’s own product, but it is very similar to the PLX PEX 8647, a model that was used on the Radeon HD 4870×2 and was developed by PLX Technology.

  Video memory with a total capacity of 2 GB (1 GB for each video chip) is made up of 16 Hynix chips marked H5GQ1h34AFR-T2C of the GDDR5 standard with an access time of 0. 4 ns, which allows them to operate at an effective frequency of up to 5000 MHz. Since the resulting frequency of the memory chips on the video card is slightly lower and amounts to 4000 MHz, there remains a good frequency corridor in reserve, which you can try to use during overclocking.

  Placing two video card chips on just one printed circuit board forced the developers to complicate the power system quite a lot. Each GPU is served through three power phases by a separate converter, and the converter circuits themselves are identical.

  One VT1157SF key and 8 ceramic capacitors per phase. ATI uses a built-in CPLA-3-50 induction circuit in this converter (performs the function of the usual single “cube” chokes for all three phases).

  Each of the two Volterra VT1165MF controllers controls the converter of its corresponding graphics chip. This type of controller has the ability to adjust the voltage by software.

  The third Volterra VT1165MF controls the converter that powers the memory controller (VDDCI). This converter has two phases using the CPL-2-50 dual inductor circuit. The memory is powered through a pair of simplest single-phase converters (one for each “set” of microcircuits) controlled by VT232WF controllers, which makes it impossible to control the memory supply voltage by software.

  As you can see in the photos above, one of the phases of each video processor power converter is left unsoldered. Also, the six-pin auxiliary power connector soldered here can be easily replaced with an eight-pin one, the place and holes for the legs are already provided.

  All the content of the board, as expected for the «top» solution of the line, is assembled with high-quality components. Many capacitors have been replaced with solid state ones, and those that remain are also made using technology that provides increased reliability and high performance.

  On the reverse side of the board, only the remaining half of the memory chips and small matching elements can be noted.

  The cooling system itself consists of several parts. The metal frame, made up of two plates, through the thermal interface comes into contact with all hot elements of the board — video memory chips and elements of the power subsystem. A separate design is used to cool the GPU — a massive aluminum heatsink with a thick copper substrate (evaporator), which is in direct contact with the GPU crystals and the switching chip.

  We used the FurMark utility to evaluate the efficiency of the cooling system, and detailed monitoring was carried out using GPU-Z and MSI Afterburner.

  Working at stock frequencies and controlling the turbine speed automatically, the GPU warmed up to 84°C, although one of the additional thermal sensors showed a temperature of 87°C. At the same time, the turbine rotation speed was 2874 RPM, which is approximately 60% of the maximum, and the entire cooler worked with little noise. Such results indicate an acceptable efficiency of the cooling system with a fairly low noise in automatic mode, but this picture will obviously not change for the better when overclocked.
