Apparently feeling the heat from the NVidia G300 chipset with 512 processors onboard, AMD is planning three new DX11-compliant cards with up to 1200 processors, all at the (currently flaky) 40nm process.
RV870 will probably be named as Radeon HD 5870 according to AMD’s naming scheme, and RV840 is called as Radeon HD 5850, and R800 is known as Radeon HD 5870X2.
Powered by 1200*2 stream processors, Radeon HD 5870X2 is said to feature GDDR5 memory, core/memory clock of 950/1150MHz, and bandwidth of 286GB/s.
