Besides analysing performance between cards we tend to forget that Cypress is outputting better quality pictures thanks to improved AF ....

Anyway my Sapphire HD5870 with Dirt2 coupon should be in my PC by tomorrow
Cache increase is due to ALU increase.
There was a slide showing ~10% IPC increase with the ALUs.
Interpolation is being done on the shaders now.
The better AF algorithms come at a supposed no performance impact.
