Notes
As we stated at the outset, with X800 ATI has decided to refine the formula that made the RADEON 9700 and RADEON 9800 series so successful. By moving to 0.13-micron, they’re able to integrate 16 “extreme pipelines” into the flagship RADEON X800 XT Platinum Edition without producing a huge die. The new graphics core weighs in at 160 million transistors, which pales in comparison to NVIDIA’s GeForce 6800 at 222 million. The million dollar question many are asking right now are where do NVIDIA’s extra transistors come from?
Unfortunately, the answer is hard to determine, as NVIDIA has kept many details of its core architecture under wraps, but it’s conceivable that some of those extra transistors are necessary to provide GeForce 6800’s FP32 precision (X800 continues to rely on FP24).
