IC203 - Sony CXD8514Q - Old 160pin GPU for use with Dual-ported VRAM
Unlike the later 208pin GPU's, the old 160pin GPU has less supply pins, and, it doesn't have a 24bit RGB output (nor any other video output at all), instead, it's used with a RGB D/A converter that reads the video data directly from the Dual-ported VRAM chips (ie. from special RAM chips with two data busses, one bus for GPU read/write access, and one for the RGB video output)...."
Нормальный GPU на 208 ног
