The Playstation GPU 600nm was a performance-segment gaming console graphics solution by Sony, launched on December 3rd, 1994. Built on the 600 nm process, and based on the GTE graphics processor, in its CXD8514Q variant, the device does not support DirectX. The GTE graphics processor is an average sized chip with a die area of 128 mm² and 1 million transistors. It features 2 pixel shaders and 1 vertex shader 3 texture mapping units, and 1 ROP. Sony includes 1 MB VRAM memory, which are connected using a 32-bit memory interface. The GPU is operating at a frequency of 53 MHz, memory is running at 33 MHz.
Its power draw is rated at 11 W maximum. The console's dimensions are 270 mm x 60 mm x 188 mm, and it features a igp cooling solution. Its price at launch was 299 US Dollars.
