Today, AMD shipped the Radeon HD 5870, the first GPU to support the DirectX11 feature set. Most of the resources have been doubled in comparison to AMD’s previous top GPU, including two triangle rasterization units. The Tech Report has a nice writeup – to help make sense of the various counts of ALUs / “wavefronts” / cores / etc. I recommend reading the slides from Kayvon Fatahalian’s excellent presentation at SIGGRAPH this year.
