Direct3D Version 9.0c, Shader Model 3.0

ATI's "R520" core (codenamed Fudo) is the foundation for a line of DirectX 9.0c 3D accelerator X1000 video cards. It is ATI's first major architectural overhaul since the "R300" core and is highly optimized for Shader Model 3.0. The Radeon X1000 series using the core was introduced on October 5, 2005. ATI plans the successor to the R500 series with the R600 series some time in 2007. Image File history File links Download high-resolution version (761x737, 288 KB) Source: http://ati. ...

Features

The R520 core architecture is referred to by ATI as an "Ultra Threaded Dispatch Processor". This refers to ATI's plan to boost the efficiency of their core, instead of going with a brute force increase in the number of processing units. A central pixel shader "dispatch unit" breaks shaders down into threads (batches) of 16 pixels (4x4) and can track and distribute up to 128 threads per pixel "quad" (4 pipelines each). When one of the shader quads becomes idle, due to a completion of a task or waiting for other data, the dispatch engine will assign the quad with another task to do in the meantime, with the overall result being a greater utilization of the shader units, theoretically. With such a large number of threads per "quad", ATI created a very large general purpose register array that is capable of multiple concurrent reads and writes and has a high-bandwidth connection to each shader array. This provides temporary storage necessary to keep the pipelines fed by having work available as much as possible. With chips such as RV530 and R580, where the number of shader units per pipeline triples, the efficiency of pixel shading drops off slightly because these shaders still have the same level of threading resources as the less endowed RV515 and R520.

The next major change to the core is with its memory bus. R420 and R300 had nearly identical memory controller designs, with the former being a bug fixed release designed for higher clock speeds. R520, however, differs with its central controller (arbiter) that connects to the "memory clients". Around the chip there are two 256-bit ring buses running at the same speed as the DRAM chips, but in opposite directions to reduce latency. Along these ring buses are 4 "stop" points where data exits the ring and going into or out of the memory chips. There is actually a fifth stop, one that is significantly less complex, designed for the PCI Express interface and video input. This design allows memory accesses to be far quicker though lower latency by virtue of the smaller distance the signals need to move through the GPU, and by increasing the number of banks per DRAM. Basically the chip can spread out memory requests faster and more directly to the RAM chips. ATI claims a 40% improvement in efficiency over older designs. Again, the smaller cores such as RV515 and RV530 receive cutbacks due to their smaller, less costly designs. RV530, for example, has two internal 128-bit buses instead. This generation has support for all recent memory types, including GDDR4. In addition to ring bus, each memory channel now has the granularity of 32-bits, which improves memory efficiency when performing small memory requests.

The vertex shader engines were already of the required FP32 precision in ATI's older products. Changes necessary for SM3.0 included longer instruction lengths, dynamic flow control instructions, with branches, loops and subroutines and a larger temporary register space. The pixel shader engines are actually quite similar in computational layout to their R420 counterparts, although they were heavily optimized and tweaked to reach high clock speeds on the 90 nm process. ATI has been working for years on a high-performance shader compiler in their driver for their older hardware, so staying with a similar basic design that is compatible offered obvious cost and time savings.

At the end of the pipeline, the texture addressing processors are now uncoupled from pixel shader, so any unused texturing units can be dynamically allocated to pixels that need more texture layers. Other improvements include 4096x4096 texture support and ATI's 3Dc normal map compression sees an improvement in compression ratio for more specific situations.

Finally, the R5xx family introduced a more advanced onboard motion-video engine. Like the Radeons since the R100, the R5xx can offload almost the entire MPEG-1/2 video pipeline. The R5xx can also assist in Microsoft WMV9/VC-1 and MPEG H.264/AVC decoding, by a combination of the 3D/pipeline's shader-units and the motion-video engine.

As is typical for an ATI video card release, a selection of real-time 3D demonstration programs were released at launch. ATI's development of their "digital superstar", Ruby, continued with a new demo named The Assassin. The demo showcased a highly-complex environment, with high dynamic range lighting (HDR) and dynamic soft shadows. Ruby's latest nemesis, Cyn, was composed of 120,000 polygons.

Information on the console first came through viral marketing campaigns and it was officially unveiled on MTV on May 12, 2005, with detailed launch and game information divulged...


Display output units also support dual-link DVI output, and HDCP. However, using HDCP requires external ROM to be installed, which were not available for early models of the video cards. RV515, RV530, RV535 cores include 1 single and 1 double DVI link; R520, RV560, RV570, R580, R580+ cores include 2 double DVI links. For other meanings of DVI, please see DVI (disambiguation). ...

X1300 series

The X1300 series is the budget card of the X1000 series. It replaces the X300/X600/X550 series from the previous generation, and shares similar capabilities. The chip carries a 4 pipeline design, similar to those older cards. However, it has all the same capabilities of the higher end boards. In fact, it is said that the chip uses 1 "quad" (4 pipelines per quad), whereas the faster boards use just more of these "quads". For example, the X1800 uses 4 "quads". This modular design allows ATI to build a "top to bottom" line-up using identical technology, saving time and money. Also, the X1300 has more modest power-draw requirements (30 watts), so it runs cooler and fits in smaller cases. The ATi Radeon X Series is the latest offering from graphics card manufacturer ATi Technologies. ...


The X1300 series used the RV515 core. There are 3 main variations of the X1300. The HyperMemory variant is quite different from the regular X1300. The local memory is clocked at 400 MHz, higher than the standard X1300, but its bus width is very limited at 32-bit, meaning it has far less available local memory bandwidth. This lowers the cost of the board (to ATI) significantly by reducing board complexity and using fewer and cheaper RAM chips. The onboard memory plays the role of a sort of cache, while most memory operations are performed on system RAM instead. The X1300 Pro gets faster memory, using DDR2 memory as compared to the DDR memory of the normal X1300. HyperMemory is ATI Technologies method of using a PCs main system RAM as part of or all of the video cards framebuffer memory on their line of Radeon video cards and motherboard chipsets. ...


Quite recently, VisionTek, a partner of ATI, ported the Radeon X1300 to the PCI bus.[2] This is ATI's very first DirectX 9 chip available on PCI; until now NVIDIA has had this niche all to itself, except for the now-discontinued XGI Technology Volari V3XT. DirectX 9 on PCI is a rather small niche for now, but with Windows Vista demanding DirectX 9 for its signature Windows Aero interface, it is likely to grow dramatically as those who bought integrated-graphics systems without AGP or PCIe slots in the last few years prepare to upgrade to Vista. The X1300 is also currently the only widely available PCI-Express x1 video card, manufactured by HIS.

In September 2006, the X1300XT was released, which is a X1600Pro with lower clock settings. Some manufacturers have decided to implement GDDR3 memory instead of the regular DDR2 memory, and overclock the RV530 GPU to match the X1600XT/X1650PRO clocks. A X1300XT with such memory and clocks is a X1600XT/X1650Pro in disguise.


X1400 series

A slightly faster Mobility Radeon X1300. Uses the same GPU core as X1300, but with a higher clock speed. Performance comparisons put it well behind X1600 but ahead of X600. [3]

X1600 series

X1600 uses the RV530 core, a core that is quite a bit different from the RV515 of X1300 and the R520 of X1800. The X1600 is positioned to replace Radeon X600 and Radeon X700 as ATI's mid-range GPU. The ATi Radeon X Series is the latest offering from graphics card manufacturer ATi Technologies. ... The Radeon R420 core from ATI Technologies was their 3rd-generation DirectX 9b-capable graphics chip. ...


It shares design philosophy with the X1900, in that it has a far different ratio of pixel shader processors. ATI has stated that the X1600 is designed with a far greater shader computational load, a prediction of future game workloads. Whereas the X1300 and X1800 have an equal pixel shader to texturing unit ratio, which targets a more equal workload of shaders and texturing in games, the RV530 of X1600 alters this to 12 pixel shaders and 4 texturing units. The chip's single "quad" has 3 pixel shader processors per pipeline. This means the chip has the same texturing ability as the X1300 at the same clock speed, but with its 12 pixel shaders it encroaches on X1800's territory in shader computational performance. While the performance is no where near that of an x1800 it still manages to lead the x1300 by a decent margin across the board. The X1600 also receives a boost in the vertex shader department, with the addition of 3 more units (total of 5) over the X1300. Its architecture is reflected in its performance; although the X1600 XT is slower than the nVidia 6600GT in older games, it outperforms it in newer games that utilize more intense shader effects.


The X1600's core clock speeds are similar to X1300's while the memory attached is usually clocked higher. However, benchmarks show that the X1600 is a decent step up from the x1300. The reasons for this is that the X1600 while having some of the same limitations has much greater ability to process complex shaders having triple the number of pipelines. Unfortunately for ATI, benchmarks also show that the X1600's intended competitor, the nVidia 7600GT, is a much faster card despite being comparably priced.


X1650 series

The X1650 series has 2 parts, which are quite different performance wise. The X1650Pro uses the RV535 core (which is a RV530 core manufactured with the newer 80nm process). Its clock speeds are almost the same compared to the X1600XT; so the only advantage of the X1650Pro is both lower power consumption and heat output, which translate into higher overclocking headroom. The other part, the X1650XT uses the newer RV570 core (also known as the RV560) although cut down in processing power (note that the fully fledged RV570 core powers the X1950Pro, a high performance card) to match its main competitor, nVidia's 7600GT. The X1650XT has a disadvantage, though: it consumes a little more power, and feeds from the PSU. The 7600GT outputs less heat when in full load, and doesn't need external power.


X1700 series

The X1700 series is mainly based around the mobility strain used in Notebooks. It represents a small step up from the X1600 series, and retains dedicated video memory.


Currently, the official Catalyst drivers from the AMD website do not offer support for the X1700. Instead users must resort to modded drivers or drivers from their laptop manufacturers (often outdated).


X1800 series

Originally the flagship of the X1000 series, the X1800 series was released with little fanfare due to the rolling release and the gain by its competitor at that time, NVIDIA’s GeForce 7800 series. The reason for the delayed release was that ATI engineers had found a bug within the core caused by a faulty 3rd party 90 nm chip design library which greatly hampered clock speed ramping, and so they had to "respin" it for another revision. The problem had been almost random in how it affected the prototype chips, making it quite difficult to finally identify. When the R520 hit the market in late 2005, the X1800 was the first high-end 90 nm GPU. ATI opted to fit the cards with either with 256 MiB or 512 MiB on-board memory (foreseeing a future of ever growing demands on local memory size). The X1800XT PE was exclusively on 512 MiB on-board memory. The X1800 replaced the R480-based Radeon X850 as ATI's premier performance GPU. Image File history File links RX1800Series_Chrome_H_lg. ...

For more background on this topic, see Radeon. ...


With R520's delayed release, its competition was far more impressive than it would have been if the chip had made its originally scheduled Spring/Summer '05 release. Like its predecessor X850, the R420 chip carries 4 "quads" (4 pipelines each), which means it has similar texturing capability if at the same clock speed as its ancestor, and the NVIDIA 6800 series. Contrasting the X850 however, R520's shader units are vastly improved. Not only are they fully Shader Model 3 capable, but ATI introduced some innovative advancements in shader threading that can greatly improve the efficiency of the shader units. Unlike the X1900, the X1800 has 16 pixel shader processors as well, and equal ratio of texturing to pixel shading capability. The chip also ups the vertex shader number from 6 on X800 to 8. And, with the use of the 90 nm Low-K fabrication process, these high-transistor chips could still be clocked at very high frequencies. This is what gives the X1800 series the ability to be competitive with GPUs with more pipelines but lower clock speeds, such as the NVIDIA 7800 and 7900 series that use 24 pipelines. The High Level Shader Language ( HLSL ) is a shader language developed by Microsoft for use with Direct3D, and is very similar to Cg. ... A Low-K dielectric is one with a small dielectric constant. ...


X1800 was quickly replaced by X1900 because of its delayed release. X1900 was not behind schedule, and was always planned as the "spring refresh" chip. However, due to the large quantity of unused X1800 chips, ATI decided to kill 1 quad of pixel pipelines and sell them off as the X1800GTO.


X1900 series

ATI Radeon X1900 advertisement, using the R580 core

The X1900 series fixes several flaws in the X1800 design and adds a significant pixel shading performance boost. Interestingly, the R580 core is pin compatible with the R520 PCBs meaning that a redesign of the X1800 PCB was not needed. X1900 boards carry either 256 MiB or 512 MiB onboard GDDR3 memory depending on the variant. The primary change between R580 and R520 is that ATI changed the pixel shader processor per pipeline ratio. The X1900 cards have 3 pixel shaders on each pipeline, giving a total of 48 pixel shader units. ATI has taken this step with the expectation that future videogames will be more pixel shader intensive than previous ones.

The Radeon X1900GT, simply an X1900XT that has been clocked lower and 4 pixel processors disabled, supports Crossfire without a master card. It was created to compete with the 7900GT, though it trailed in performance, it was also generally cheaper. A shortage of R580 cores that can clock to 575MHz resulted in the creation of a Revision 2 X1900GT running at 512MHz, however with a higher memory clock (1320MHz). They are most easily recognizable by the new reference heatsink, the same used on the X1950Pro.


X1950 series

The X1950 XTX is a graphics board using the R580+ GPU. It is unclear what has been changed in this new revision as it is clocked at the same speed as the R580 aboard X1900 XTX and manufactured on the same 90 nm silicon process. For a performance gain, the new X1950 XTX uses GDDR4 memory, a new RAM technology that offers lower power consumption per clock and offers a significantly higher clock rate ceiling.[1] X1950 XTX clocks its RAM at 1 GHz (2 GHz DDR), providing 64.0 GB/s of memory bandwidth, a 29% advantage over the X1900 XTX.

The X1950 Pro is released on 17 October 2006 with a MSRP of $200 and intended to replace the X1900GT in the competitive <=$200 market segment. The X1950 Pro GPU is built from the ground up with only 12 texture units and 36 pixel shaders. It is based on the 80nm RV570 core, allowing to draw and dissipate less power than the 90nm R580-based cards.


The X1950 Pro is the first ATI card that supports native Crossfire implementation by a pair of internal Crossfire connectors, which eliminates the need for the unwieldy external dongle found in older Crossfire systems. Performance-wise, the X1950 Pro trails slightly behind a X1900XT 256 MiB, due to a deficit of 4 texture units and 12 pixel shaders, as well as lesser GPU and memory clocks.[2]


PowerColor, an ATi partner, was one of the first to announce an AGP X1950Pro, this card is also shown to come pre-installed with an Accelero X2 cooler. Other ATI partners such as Visiontek, GeCube and Sapphire have also started to ship AGP X1950Pro cards in both 256 and 512 MiB versions. The X1950GT was released in January and is basically an underclocked X1950 PRO.


On October 20, there was a quiet launch of the X1950XT, though none were actually on stock at retailers. The X1950XT features the same board, cooler, and GDDR3 memory as the X1900XT ,however, using the R580+ core with higher clock speeds. The only AGP version has been released by GeCube in April 2007. First announced at CeBIT, GeCube advertises the card for Overclocking thanks to the large three-slot heatsink. A crowded exhibition hall during CeBIT 2000. ...

  • Bold rows indicate major core types.
  • 1 (Texture Units:Pixel Shaders:ROPs:Vertex Shaders). All chips of this generation have 1 texture mapping unit (TMU) per pixel pipeline, but the operation of TMU is not tied to any particular pixel pipe.
  • 2 MTex/s = Million Texels per second, a measure of texturing fillrate. All chips of this generation have equal texture and pixel fillrates because of having only a single TMU per pipeline.
  • 3 MTri/s = Million triangles per second, a measure of the core's geometric calculation capabilities. Related to core speed and the number of vertex shaders.
