Overclock.com heeft een errug interessant artikeltje in elkaar geklust over de NV10 drivers in Win2000 (die zitten er standaard in!). Win2k blijkt drie NV10 versies te kennen: de NV10, NV10 GL en NV10 Ultra. Hmm...
It included support for the GeForce (NV10)!!! This really got me thinking, and I came up with the following theories:
The GeForce has the same micro architecture as the TNT.
If the drivers are the same, then the two chips must use the same instruction set. It looks like they added another pair of texture units, and doubled the bus to accommodate them (256bit vs. 128). From this we could expect the GeForce to run twice as fast as a TNT, at the same clock speed. Also, this could also explain why Nvidia is able to bring the GeForce to market so quickly - because they're basically putting two TNT's on one chip.
Nvidia will be coming out with different versions of the GeForce.
They listed a NV10 GL and a NV10 Ultra in the list of devices. I expect the Ultra model to be based on Nvidia's new .22u process. This is because the standard model comes with a heatsink/fan, unlike the standard TNT-2's. So the only way to go significantly faster is with a better process. I would expect a core clock speed of between 150-166mhz for the ultra part vs. 120mhz for the standard part. Now, I'm not too sure about the GL part. We know the GeForce will support OpenGL, so the GL must be some designation for a value version. I would guess the value version would use slower but cheaper 7ns ram instead of the 5ns.
