"Sony also unveiled the PS3's graphics chip, the RSX "Reality Synthesizer" based on Nvidia technology. The GPU will be capable of 128bit pixel precision, 1080p resolution, some of the highest HD resolution around. The RSX also has 512mb of graphics render memory and is capable of 100 billion shader operations and 51 billion dot products per second. It also has over 300 million transistors, larger than any processor available commercially today. It will be manufactured using the 90nm process with 8 layers of metal. The RSX is more powerful than two GeForce 6800 Ultra video cards, which would cost roughly $1000 total if bought today."
