NVIDIA's CEO confirmed during a conference call that they have cancelled the C60 chipset, it was supposed to be the GeForce 6150 and 6100 for the Intel platform but as NVIDIA lost the Intel chipset deal to ATI they decided to can the project.
I guess that it was much more than just a loss to ATI and we suspect that this chipset had some problems that they just could not override. You don’t cancel a chip that has cost you millions of dollars for nothing. But, to be fair, perhaps it was a strategic decision.It's possible that NVIDIA will use ULi to make a good entry-level Pentium 4 chipset, as this is the market where the money is.
