2002-10-18 ATI Radeon 9500 Low price version of Radeon 9700, still based on the R300 core, but with with 4 instead of 8 pipelines competing in the GeForce4 4200 Ti price range.

2002-10-24 ATI Radeon 9700 Pro Graphics chip formerly known as R300 supporting DirectX 9.0, with 107 million transistors building up 8 pipelines for 8 textures in 0.15 micron technology. 4 vertex shaders and HyperZ III will also fit in the chip. Core clock runs at 325 MHz while the 256 MB of DDR runs at 620.

2002-10-24 ATI Radeon 9700 Graphics chip formerly known as R300 supporting DirectX 9.0, with 107 million transistors building up 8 pipelines for 8 textures in 0.15 micron technology. 4 vertex shaders and HyperZ III will also fit in the chip built with a 0.15 micron process. Core clock runs at 275 MHz while the 128 MB of DDR runs at 550.

2002-11-18 Nvidia GeForce FX 5800 GeForce GPU architecture previously called Omen, NV30 and GeForce 5 shows up including 125 million transistors built with a .13 micron process. Adds floating point graphics supporting up to 128 bit calculations. Runs at 500 MHz using 8 pipelines with one TMU on each (or 4 x 2 as required) and 1 GHz DDR-II 128 bit memory. Performace double that of the GeForce 4, or 100 Jurassic Park dinosaurs at 100 frames per second (or as some witty person put it 10000 dinosaurs/s...). Handles 51 billion floating point operations/second in the pixel shader. Shown at Comdex with cards available late February.

2002-11-27 ATI Radeon 9500 Pro Budget version of the Radeon 9700 Pro

2003-05-12 Nvidia GeForce FX 5900 Successor to NV30 formerly known as NV35 with 4x2 architecture and a 8x1 mode for single texturing. Internal register file twice the size of that of NV30, removing a known bottleneck. NV30 differences from Tom's:

Some rumours indicate that the core includes Pixel Shader 3.0 support, even if no drivers support it.

2004-Q1 ATI R400 New ATI graphics high end core succeeding the R300/R350 (Radeon 9700/9800). The R400 has been delayed until 2004 due to: 3GIO, DDR-3 and DX9 pixel shader 3.0. It is renamed to R500, while the less ambitious R420 takes over in the short term.

2004-04-14 Nvidia GeForce 6800 New high-end graphics processor, succeeding NV35 (GeForce 5900). Includes Pixel Shader 3.0 and Vertex Shader 3.0 to support DirectX 9.0c (previously known as 9.1) and to include 16 "real" pipelines instead of the 4x2 architecture used previously.
Named GeForce 6800 and was to be shown at CeBIT or GDC with availability in April or May, but unveiled on April 14th.
Draws a massive 110W from two power cables. Previously known as NV40.

2005 nVidia NV50 Upcoming high end DX9.x/DX10 graphics chip said to have been in progress since 2002. Rumours has it that UnrealEngine3 specific optimizations may be included. Mostly speculation so far, however. Was thought to be canceled, and replace by the G70, but recent rumours claim that it is still in development.

2006-H1 ATI R500 High end ATI graphics chip for XBox2 built in a 90 nm process. Part of a new generation, comparable to R600 for the PC.
Early on reported to "have 10 times higher geometry and 4 times higher pixel performance compared to the RADEON X800 XT" (believe it if you want to).
May support WGF and Pixel and Vertex shaders 3.0 with 128 bit precision. Also known as Xenos.
