PlayStation 3 GPU: NV40/NV50 with XDR DRAM
A report from 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.
Naturally, the PlayStation 3 graphics processing units supports XDR DRAM memory developed by Rambus. While there is nothing new in Rambus memory for Sony, NVIDIA has never worked with memory by Rambus.
