PlayStation 3 GPU Details Materialize

A report over Japanese web-site PC Watch suggests that the PlayStation 3 graphics processing unit will use NVIDIA?s technologies found in the current NV40 generation of its own chips as well as numerous techniques developed for the next-generation part known under NV50 code-name. Still, despite of circuitries of the company?s desktop chips found in the GPU, according to NVIDIA?s chief Jen-Hsun Huang, the PlayStation 3 GPU has nothing to do with Microsoft Windows, Microsoft DirectX or OpenGL and will use Sony?s API for the console.

While there is nothing new in Rambus memory for Sony, NVIDIA has never worked with memory by Rambus.”
