AMD Delivers Performance for the Masses

It’s been one of those long nights, the type where you don’t really sleep but rather nap here and there. Normally such nights are brought on by things like Nehalem, or NVIDIA’s GT200 launch, but last night was its own unique flavor of all-nighter.

On Monday, AMD had a big press event to talk about its next-generation graphics architecture. We knew that a launch was impending but we had no hardware nor did we have an embargo date when reviews would lift, we were at AMD’s mercy.

You may already know about one of AMD’s new cards: the Radeon HD 4850. It briefly appeared for sale on Amazon, complete with specs, before eventually getting pulled off the site. It turns out that other retailers in Europe not only listed the card early but started selling them early. In an effort to make its performance embargoes meaningful, AMD moved some dates around.

Here’s the deal: AMD is launching its new RV770 GPU next week, and just as the RV670 that came before it, it will be available in two versions. The first version we can talk about today: that’s the Radeon HD 4850. The second version, well, just forget that I even mentioned that — you’ll have to wait until the embargo lifts for more information there.

But we can’t really talk about the Radeon HD 4850, we can only tell you how it performs and we can only tell you things you would know from actually having the card. The RV770 architectural details remain under NDA until next week as well. What we can tell you is how fast AMD’s new $199 part is, but we can’t tell you why it performs the way it does.

We’ve got no complaints as we’d much rather stay up all night benchmarking then try to put together another GT200 piece in a handful of hours. It simply wouldn’t be possible and we wouldn’t be able to do AMD’s new chips justice.

What we’ve got here is the polar opposite of what NVIDIA just launched on Monday. While the GT200 is a 1.4 billion transistor chip found in $400 and $650 graphics cards, AMD’s Radeon HD 4850 is…oh wait, I can’t tell you the transistor count quite yet. Let’s just say it’s high, but not as high as GT200 🙂

Again, we’re not allowed to go into the architectural details of the RV770, the basis for the Radeon HD 4800 series including today’s 4850, but we are allowed to share whatever data one could obtain from having access to the card itself, so let’s get started.

Running GPU-Z we see that the Radeon HD 4850 shows up as having 800 stream processors, up from 320 in the Radeon HD 3800 series. Remember that the Radeon HD 3800 was built on TSMC’s 55nm process and there simply isn’t a smaller process available for AMD to use, so the 4800 most likely uses the same manufacturing process. With 2.5x the stream processor count, the RV770 isn’t going to be a small chip, while we can’t reveal transistor count quite yet you can make a reasonable guess.

Clock speeds are also fair game as they are reported within GPU-Z and AMD’s Catalyst control panel:

That’s a 625MHz core clock and 993MHz GDDR3 memory clock (1986MHz data rate). We’ve got more stream processors than the Radeon HD 3870, but they are clocked a bit lower to make up for the fact that there are 2.5x as many on the same manufacturing process.












  ATI Radeon HD 4850 ATI Radeon HD 3870
Stream Processors 800 320
Texture Units I can’t tell you 16
ROPs 16 16
Core Clock 625MHz 775MHz+
Memory Clock 993MHz (1986MHz data rate) 1125MHz (2250MHz data rate)
Memory Bus Width 256-bit 256-bit
Frame Buffer 512MB 512MB
Transistor Count it’s a secret 666 million
Manufacturing Process TSMC 55nm TSMC 55nm
Price Point $199 $199

 

The rest of the specs are pretty straightforward, it’s got 512MB of GDDR3 connected to a 256-bit bus and the whole card will set you back $199. The Radeon HD 4850 will be available next week, and given that we’ve already received cards from 3 different manufacturers — we’d say that this thing is going to be available on time.

There is no linux kernel 8, so I’m guessing you mean some random distribution version 8. Which distribution?

3DMark Vantage Performance

3DMark Vantage is an outdated DirectX 10 based benchmark. It loads the graphics card with two scenes, one of a girl running away from some kind of military base located in a sea cave, and the other of a space fleet attacking a defenseless planet. Support for 3DMark Vantage was discontinued in April 2017 and it is now recommended to use the Time Spy benchmark instead.

    Part 1: Theory and Architecture

    A few days ago we wrote about the Geforce GTX 200 line the latest high-end solutions from Nvidia, now it’s time for new AMD products. But we will start with a video card, according to its market position, which does not claim to compete with the GTX 200 line. To compete with the GTX 280, Nvidia’s most expensive single-chip card, AMD is planning dual-chip solutions based on the high-frequency version of the RV770. As our readers know, AMD has moved away from its previously used strategy of releasing a special version of the chip for the high-end segment. Instead, multi-chip solutions are produced for the upper high-end (two chips on one card operate in the CrossFire mode). AMD notes the following problems inherent in large high-end chips: too high price and power consumption for most buyers, a large time delay in the development of new technical processes (less complex chips are easier to transfer to thinner technologies), etc.

    The advantages of AMD’s new («multi-chip») strategy are: the ability to produce optimal solutions for all price ranges using cards with different numbers of chips, low cost and rapid implementation of new technologies. Of course, multichips also have disadvantages. First, the most commonly used multi-chip rendering method: Alternate Frame Rendering (AFR), although it gives the largest increase in the number of frames per second, it does not increase the smoothness of rendering in the same way as the increase in «single-chip» FPS. As a result, on multi-chip systems, there are often situations with high FPS, but control lag and lack of smoothness.

    However, we will not know who will become the «king of the hill» on the graphics Olympus this summer until we test the Radeon HD 4870 X2 in comparison with the GeForce GTX 280. And now we have a potential leader in a completely different, utilitarian market segment from $200 to $300, that is, among video cards powerful enough for modern games at high resolutions with maximum settings, but also not too expensive, not particularly demanding in terms of power, small and not very heated. Has AMD succeeded in delivering the ideal card for the most mainstream market segment? Here in today’s article we will deal with this.

    And, first of all, I’m pleased with the presence of a full-fledged architectural update. So, the theoretical part promises to be very interesting, because the architectural changes in the chip are very important and long-awaited. Before reading this material, we recommend that you carefully read the basic theoretical materials DX Current, DX Next and Longhorn, which describe various aspects of modern hardware graphics accelerators and the architectural features of previous Nvidia and AMD products.

    So, AMD continues to produce graphics solutions based on 55 nm technology standards. Compared to Nvidia’s high-end 65nm chips, the more advanced process technology offers certain advantages: smaller core area, increased frequency headroom and yield percentage at high clock speeds, and likely lower cost. Compared to RV670, the new chip is even more energy efficient. It consumes quite a bit of power and has significantly higher performance than previous solutions.

    As you can see, the marking of different solutions has remained unchanged from the previous series, only the first digit has changed. Otherwise, the positioning of the HD 4870 and 4850 is roughly the same as the position of the HD 3870 and 3850 at the time of their release. Naturally, the HD 3000 series does not go anywhere, but descends into the lower price ranges.

    Two variants in the series, as usual with AMD, differ in clock frequencies, both video chip and memory. But this is not the only difference between the models of cards the older one has a new type of memory GDDR5, which gives a large bandwidth, which especially affects performance in complex anti-aliasing modes. Among other differences of the older version higher energy consumption and equipping with a two-slot cooling system.

    The amount of video memory for both cards in the reference form is the same 512 megabytes each. Although modern games are very demanding on the amount of video memory, they usually use up to 500-600 megabytes, and only sometimes more. Therefore, the amount of memory in 512 megabytes is the optimal amount of memory at the moment. Although, it would be very nice if some of the RADEON HD 4870 video cards produced by AMD partners had a larger capacity — one gigabyte. For the most demanding games like Crysis, this is important.

    RV770 Chip Architecture

    The main goal in developing the new chip was to further improve efficiency. The engineers were tasked with achieving a twofold advantage in theoretical performance compared to the previous generation chip RV670. Also, in light of recent trends, it was very important to focus on improving the chip’s non-graphical computing capabilities. At the same time, GDDR5 memory was used for the first time and the psychological barrier of one teraflop computational speed was overcome, which Nvidia with its GT200 almost fell short of.

    The RV770 architecture combines some of the previous R6xx architecture, but has been redesigned to improve performance and efficiency. Let’s take a look at the scheme of the new chip:

    It’s immediately obvious that the RV770 architecture has undergone a lot of changes compared to the architecture known to us from the R600 and RV670 chips. Both quantitative and qualitative changes were made in it, many bottlenecks were eliminated. But let’s stop at all the changes in order …

    The main part of the RV770 video chip consists of ten SIMD cores, each of which contains 16 blocks of superscalar stream processors, there are 160 of them in the chip. The superscalar nature of these processors has not changed since the RV670, so we can assume that the chip contains 160 * 5 = 800 scalar 32-bit stream processors. For 64-bit double precision calculations, the same blocks are used, only the rate of calculations is reduced.

    Other modifications were also carried out in the chip: TMU texture units were changed, their number was increased, ROP units were accelerated while maintaining their number, the memory and caching architecture was radically changed, support for a new type of GDDR5 memory was introduced, and other changes were made to increase the performance of the execution of geometric shaders and parallel non-graphical calculations.

    As we said, each of the 10 SIMD cores contains 16 superscalar stream processors (or 80 scalar) and 16 kilobytes of local memory for data storage and has its own thread control unit. Also, unlike the R6x0 and RV670, the TMUs are «tied» to SIMD, each of them has four dedicated texture modules and its own L1 texture cache. SIMD cores can communicate with each other using 16 kilobytes of global memory. As you can see, the power of texture units in the new chip is scaled along with the number of shader processors, and the ratio between ALU and TMU is 4:1.

    The stream processors remained essentially the same as in the RV670, but their density was increased (shown in the picture to scale), which made it possible to increase the number of stream processors to 800 pcs with the same manufacturing process. And to increase energy efficiency, more aggressive clock gating is used, which allows you to turn off logic blocks to reduce power consumption.

    In addition, the superscalar design of the stream processors has made it easier and more efficient for AMD to implement double precision (FP64) support using the same compute units. As a result, even with the addition of special SPs for FP64 calculations in the GT200, the RV770 has significantly better performance in such calculations, with a theoretical peak figure of up to 240 gigaflops.

    But the texturing units have changed a lot, now they are tied to SIMD, and their efficiency has been significantly improved. The designers removed the dedicated TMU pool known from previous generations of chips, implementing a solution very similar to what we see at Nvidia, with TMUs included in the SIMD cores.

    The ability to select without filtering, which was previously used separately for vertex data, has been removed. In the new chip, both texels and vertices are selected by the same blocks, which is also similar to the solution in G8x and beyond. On the other hand, each of the 40 texturing units in the RV770 is somewhat weaker than each of the 16 in the RV670, but an increased number of them, along with increased frequencies, should give a decent increase in texturing speed.

    In general, we can expect up to a 2.5-fold increase in performance with bilinear filtering of 32-bit textures, and 1.25-fold for 64-bit textures. Other features include double the bandwidth to the texture cache compared to RV670 and the ability to fetch up to 160 Fetch5/Gather4 texture values ​​per clock, which should also improve performance.

    The chip uses a new caching block design: the vertex cache is separate, the second-level cache is tied to four 64-bit memory channels, L1 caches store unique data for each SIMD block, which increases caching efficiency. The bandwidth has also been increased: up to 480 GB/s for the L1 texture cache, up to 384 GB/s between the L1 and L2 caches.

    All of the above changes to texture units and caching have resulted in RV770 texturing being twice as efficient as competing Nvidia chips (both G92 and GT200) according to the feature test from 3DMark Vantage. Consider the ROP block diagram:

    As you can see in the diagram, there are not so many qualitative changes in the ROP blocks. But, although the number of ROPs remained the same as in RV670, now they can process twice as many pixels per cycle in most cases, which is especially important when MSAA is enabled. Now the MSAA 2x and 4x algorithms are almost «free» in general, at least in terms of how ROP works. Here is a comparative table of the rate at which pixels are written to the framebuffer in different modes:

    In almost all modes, ROP efficiency is doubled, except for the simplest 32-bit color without MSAA. It should be noted and Custom Filter Anti-Aliasing (CFAA). Already the previous generation of AMD video chips offered specialized anti-aliasing filters called Custom Filter Anti-Aliasing. We have considered this method in some detail in previous articles, and the most interesting feature for anti-aliasing on AMD chips is the edge detect method used in the 12x and 24x CFAA algorithms.

    This is the highest quality method that uses the shader power of the RV670 and RV770 chips to process the image, to which MSAA has already been applied. The method is based on finding the edges of polygons (special filter) and additional filtering of these areas of the image. The method does not require additional video memory compared to the 4x and 8x MSAA modes, and also works together with adaptive anti-aliasing. The RV770 features minor improvements to speed up this and other methods, including a dedicated fast link between ROPs and shader processors.

    Interestingly, according to some reports, RV770 does not use shader processors with MSAA, as it was done in R6xx and RV670 chips. For standard MSAA algorithms, the capabilities of hardware ROP blocks are used, and only for the mentioned programmable CFAA shader resolve.

    Other important changes in the chip include the replacement of the previously widely advertised, but never successful, ring bus with a central hub architecture. In RV770, memory controllers are located at the edges of the chip, next to the main traffic consumers, and the hub distributes data flows between the already mentioned blocks, as well as PCI Express, CrossFireX, UVD2, output controllers.

    The company estimates that the new memory interface design has resulted in a significant increase in bandwidth efficiency. In addition, the controller supports new GDDR5 memory modules that operate at effectively quadruple speeds up to 3.6-4 GHz and higher, which gives memory bandwidth up to 120 GB/s using an inexpensive 256-bit interface.

    The prime cost is important, because in order to increase the bandwidth of GDDR3 memory, you have to use a 512-bit bus, which leads to the fact that both the chip and its packaging increase. And the cards themselves are getting bigger and more complex, consuming more and more energy. Switching to GDDR5 allows you to increase performance by 2-3 times with even smaller chip sizes with less power consumption.

    AMD has been actively involved in the development of the GDDR5 standard, along with all major memory manufacturers (Hynix, Qimonda and Samsung) and JEDEC. The development of this type of memory took about three years from the beginning of development to the final specification, and at AMD even more. It is assumed that GDDR5 will operate at speeds up to 7 GHz effective (quadruple) frequency. The first chips that support 1.5 V (as opposed to 2.0 V for GDDR3) and have a density of 0.5-2 Gbps offer speeds up to 1000*4=4.0 GHz.

    In the architectural part, it remains to give a chip diagram, which indicates the areas occupied by various blocks of the GPU. As you can see, most of the chip is occupied by 800 stream processors, significant parts of the chip were left behind by texture processors and various controllers. And the rest, apparently, is occupied by ROP blocks, second-level caches and other auxiliary logic.

    Just like in the GT200, the RV770 has increased the efficiency of geometry shader execution, or rather, the performance of creating vertex data. The number of geometry shader execution threads supported has been quadrupled, and the vertices generated in them can be stored on the chip in a greater number.

    The tessellation block has also been modified. It is now compatible (whatever that means) with DirectX 10 and 10. 1, and also supports instancing. We will definitely look at the execution speed of geometric shaders in our synthetic tests in the next part of the article, and more about tessellation is written in the R600 base material.

    Summing up, the chip can be called RV-«work on errors»-770. As we can see, all the obvious mistakes and flaws in the design of the RV670 have been corrected. Although the number of ROPs has remained unchanged, they now run twice as fast, doing twice as much work per cycle in most cases. As a result, the MSAA 2x and 4x algorithms for the RADEON HD 4800 series are almost «free» in terms of ROP operation, although bandwidth limitations can still reduce performance.

    But these are not the only changes, work on the bugs continued for TMUs, which were completely redesigned. The dedicated TMU pool has been removed, and the new solution includes TMUs in each of the ten SIMD cores. Other important changes include the change from the ring bus to a hub architecture. Interestingly, almost all of the fixes bring the RV770 chip closer to what we see in Nvidia’s solutions. It looks like ATI(AMD) has learned to admit their mistakes and correct them. It is commendable, it remains to test the speed of new solutions in practice.

    Non-graphical computing

    It’s no wonder that both major video chip manufacturers have recently paid special attention to non-graphical computing on video cards. Gradually, GPU computing is beginning to take root both in scientific fields and in conventional software that we use in everyday tasks. So, updated versions of solutions for image processing (Adobe Photoshop), video data processing and transcoding (Adobe Premier, Cyberlink PowerDirector) have already been released or will soon be released. And hardware acceleration of physical calculations in games is already used in Nvidia PhysX.

    In order to increase the performance and flexibility of non-graphical parallel calculations, several changes have been made to the RV770:

    • Faster floating point calculations (FP64). Current RV770-based solutions peak at 240 gigaflops, about five times faster than the fastest four-core CPU. Calculation accuracy meets the requirements of the IEEE 754 standard.
    • Increased random write and read performance (MemExport/MemImport). Scatter and gather operations run at twice the speed of the RV670, with a maximum throughput of sixteen 64-bit exports or eight 128-bit exports per clock.
    • Fast creation of computational threads, which means reduced overhead for parallel computing.
    • Data exchange between computational threads. Local memory is allocated for each SIMD block, separate from the texture cache, and global data exchange between all SIMD blocks is also possible. According to the company, these changes have resulted in a sevenfold increase in performance in Fast Fourier Transform (FFT) calculations.
    • Fast bit shift operations available to all SP blocks. Compared to the previous generation, a performance increase of 12.5 times has been achieved. This change speeds up the tasks of processing and encoding video data, as well as compression and encryption algorithms.

    AMD provides the following graph of the relative performance of RV670 and RV770 in synthetic computing tasks. The average difference in speed between two generations is 2.5-3 times (which roughly corresponds to the increased number of stream processors), but the maximum gain was obtained in the Fast Fourier Transform (FFT) algorithm the difference in speed was seven times. Encryption using the AES algorithm has accelerated almost 4 times. This is already the impact of changes in architecture.

    ATI Avivo technology

    The RV770 integrates the second generation Unified Video Decoder (UVD 2) video processing chip. It hardware decodes video data in all the most important formats: H.264, VC-1 and MPEG2, has the ability to simultaneously decode two full-format (1080p) streams, improved video post-processing capabilities, in addition to previously known DVD video upscaling to HD resolutions, and also dynamic contrast adjustment.

    Other important innovations include support for 24-bit and 30-bit output devices at resolutions up to 2560×1600 via the new DisplayPort connector. Support for HDMI output has not gone away with the help of special DVI-2-HDMI adapters that support resolutions up to 1920×1080. And from the real improvements, we can note the sound controller. It now supports uncompressed 48kHz stereo audio or 8-channel (7.1) AC3 streaming at bit rates up to 6.144Mbps.

    There has been a new surge of interest in hardware accelerated encoding and transcoding of video data from one format to another. AMD calls it Accelerated Video Transcoding (AVT), H.264 and MPEG2 are supported. Declared transcoding of 1080p video streams faster than 30 FPS that is, faster than real time, on the fly.

    In fact, GPU encoding speeds are about the same as those of Nvidia transcoding an hour-long 1080p video took almost 10 hours on a universal Core 2 Duo E8500 processor and 32 minutes on a solution from the RADEON HD 4800 series. Then yes, the new GPUs are about 20 times faster than fairly fast dual cores. For complete happiness, Cyberlink PowerDirector 7 should soon be released with support for encoding using video chips.

    PowerPlay 9 Power Management0186

    The ATI PowerPlay dynamic power management technology, which came from notebook video chips, has received further improvements. Recall that the essence of the technology is that a special control circuit in the chip monitors its work load and determines the optimal operating mode by controlling the operating frequency of the chip, memory, supply voltage and other parameters, optimizing power consumption and heat dissipation. So, in 2D mode with a low load on the GPU, the voltage and frequencies will be reduced as much as possible, as well as the fan speed, in the mode of a small 3D load, all parameters will be set to average values, and at maximum GPU operation, the frequencies with voltage will be set to the highest value.

    For power management, a corresponding microcontroller is integrated on the chip, which constantly monitors temperature sensors and bus activity, both on-chip and external PCI Express. The driver controls everything, the frequencies of the chip and memory, voltages, fan speeds are controlled and changed, and idle GPU blocks can also be disabled. Due to the updated power management technology and other modifications in the chip, compared with the previous generation of video cards, a twofold increase in efficiency, expressed in performance per watt, was achieved.

    So, today we got acquainted with the theoretical features of the new RV770 chip, in the next part of the article there will be a practical part of the study, in which we will find out how the performance of new solutions based on the RV770 chip compares with the speed of previous solutions from AMD and competing video cards from Nvidia. The most interesting thing is how much the above-mentioned architectural improvements in the RV770 have affected its performance.
