Nevim, nevim :

OK, I chanced my arm again with NVidia's PR, and was told this:

"Although we cannot comment on technical details, I can tell you that the
GPU is a custom version of NVIDIA's next generation GPU, which is not
Cell based."

edit:

I asked him to clarify if he meant both Nvidia's next-gen GPU and the PS3 GPU would not be cell-based and he replied:

"I can just comment on NVIDIA's next generation GPU which is not cell
based."
Nejak se mu o PS3 GPU nechce vyjadrovat

EDIT: Nejak se nam ty vyjadreni koukam rozchazeji....
"It will be a custom GPU, not based on an existing architecture," said Jen-Hsun Huang, speaking at an "Editor's Day" for reporters and analysts at the company's Santa Clara, Calif.-based headquarters. "It will be based on an architecture under development." Neither Nvidia nor Sony disclosed further details about the new architecture.
