The Playstation 3 GPU 65nm was a high-end gaming console graphics solution by NVIDIA, launched in August 2008. Built on the 65 nm process, and based on the RSX-65nm graphics processor, in its RSX-CXD2991 variant, the device does not support DirectX. The RSX-65nm graphics processor is an average sized chip with a die area of 186 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 58 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 499 US Dollars.
