Matrox PX-A1
Matrox's PX-A1 GPU uses the PX architecture and is made using a 90 nm production process at UMC. PX-A1 supports DirectX 8.1. For GPU compute applications, OpenCL version N/A can be used. It features 2 pixel shaders and 2 vertex shaders, 8 texture mapping units and 2 ROPs. Due to the lack of unified shaders you will not be able to run recent games at all (which require unified shader/DX10+ support).
