History lesson time
1. TNT Fall 1998 180 megatexel fillrate, 110mhz SDRAM (1.76GB/sec memory bandwidth) 32 bit color single pass multitexturing
2. TNT2 Spring (Late spring release to users) 250 megatexel fillrate 150mhz SDRAM (2.1GB/sec memory bandwidth) refresh
3. Geforce SDR/DDR (late fall release ) fixed function T+L, 2 matrix blending, Dot Product 3 bump mapping , Nvidia Shading Rasterizer (note I included it here because I believe it's as capable as the GTS in this regard just slower 4 pixel pipelines 120mhz core either 166mhz SDR (2.626GB/sec memory) or 150mhz DDR (4.8 GB/sec memory)
4. Geforce2 GTS Spring refresh 200mhz core 2 textures per pixel pipe 166mhz DDR (5.3GB/sec memory) same featureset as SDR/DDR)
5. Fall refreshGeforce2 Ultra quite simply , NV20 wasn't ready in time or I'm not sure Nvidia wouldn't have released Geforce3 lin fall 2000 if they could. 250mhz core 230mhz DDR (7.3GB memory bandwidth)
6. Geforce3 Spring 2001 product programmable pixel and vertex shaders, Quincunx 200mhz core/ 230mhz DDR (7.3GB memory bandwidth)
7. Geforce3 Ti500/200, quite simply this is a speed-binned Geforce3 not really a refresh. 240mhz core/250 mhz DDR no other changes except enabling 3d textures and shadow buffers which were always a part of the Geforce3 featureset
8. Geforce4 . By many accounts (Tom's Hardware, Anandtech) Geforce4 was ready to launch last year. Had 8500 been launched differently , Nvidia might have launched Ti4200/4400 ( i doubt they would have gotten 300mhz on Geforce4 in November 2001)
What does this tell us? Nothing
. I would take note of Dave Wavy's interview with Nvidia at the European Geforce4 launch, I would also take note of Jen-Hsun Huang saying their next part won't be called GeforceXX.
