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.
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:
- DDR(-I) memory at 425 MHz instead of DDR-II memory at 500 MHz
- Memory bus widened from 128 to 256 bits
- Memory bandwidth of 27.2 GB\/s (NV35), up from 16 GB\/s (NV30)
- GPU clockspeed decreased from 500 MHz to 450 MHz
- Ultra versions of the FX 5900 will carry 256 MB RAM
- New, much less noisy cooling solution
- CineFX gains new "UltraShadow" feature and is now called CineFX 2.0
- IntelliSample optimizations, especially color compression, have been improved and renamed IntelliSample HCT (High Compression Technology)
- In addition to the FX 5900 Ultra 256 MB ($499 ESP), a standard FX 5900 128 MB ($399 ESP), and a GeForceFX 5900 Value 128 MB ($299 ESP) will also be offered.
Some rumours indicate that the core includes Pixel Shader 3.0 support, even if no drivers support it.
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.
- 6800LE: 8 pipes, 4 shaders
- 6800: 12 pipes, 5 shaders
- 6800GT: 16 pipes, 6 shaders
- 6800 Ultra: 16 pipes, 6 shaders
2004-05-04 ATI Radeon X800 New high end graphics chip succeeding the R350/R360 based on a completely new design also known as project Loki. Was to be shown at Comdex in November-03, but was only shown to NDA-signing people on CeBIT-04 and launched to the rest of us in May. Was earlier said to support unified DX 9.0c and Pixel and Vertex Shaders 3.0, but only DirectX 9.0b is supported.
The R420 is a simplified version of the R400 (now R500) to get a new high-end chip out quicker. R420 still uses 24 bit precision (96 bit in total) but adds 3Dc compression.
Native PCI-Express support shows up in the R423 (X800 PCI-E), formely known as X880 on June 1st.
Two versions are launched: The X800 Pro includes 12 pipelines with availability now, while the X800 XT uses 16 and ships on May 21st. A low cost X800 SE with only 8 pipelines is also planned. Previously known as R420.
