The Playstation 2 GPU 90nm was a performance-segment gaming console graphics solution by Sony, launched on May 26th, 2005. Built on the 90 nm process, and based on the EE+GS-90nm graphics processor, in its CXD2953AGB variant, the device does not support DirectX. The EE+GS-90nm graphics processor is a relatively small chip with a die area of only 86 mm² and 54 million transistors. It features 16 pixel shaders and 2 vertex shaders, 8 texture mapping units, and 16 ROPs. Sony includes 4 MB eDRAM memory, which are connected using a 2560-bit memory interface. The GPU is operating at a frequency of 147 MHz, memory is running at 150 MHz.
Its power draw is rated at 45 W maximum. The console's dimensions are 230 mm x 28 mm x 152 mm, and it features a igp cooling solution. Its price at launch was 199 US Dollars.

Parallel rendering processor with embedded DRAM
"Graphics Synthesizer" (GS) clocked at 147.456 MHz

Programmable CRT controller (PCRTC) for output

Pixel pipelines:
16 without any texture mapping units (TMU), however half of pixel pipelines can perform texturing, so fillrate is either 16 pixels per clock with untextured 2400 Mpixels; or 8 pixels per clock with 1200 megapixels with bilinear texturing, and 1200 megatexels (bilinear).

Video output resolution:
Variable from 256×224 to 1920×1080
