The Playstation 3 GPU 90nm was a high-end gaming console graphics solution by NVIDIA, launched in November 2006. Built on the 90 nm process, and based on the RSX-90nm graphics processor, in its RSX-CXD2971 variant, the device does not support DirectX. The RSX-90nm graphics processor is an average sized chip with a die area of 258 mm² and 300 million transistors. It features 24 pixel shaders and 8 vertex shaders, 24 texture mapping units, and 8 ROPs. NVIDIA includes 256 MB GDDR3 memory, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 550 MHz, memory is running at 650 MHz.
Its power draw is rated at 80 W maximum. The console's dimensions are 325 mm x 98 mm x 274 mm, and it features a igp cooling solution. Its price at launch was 599 US Dollars.
