ATI Radeon HD 5890 Coming in Q1 2010

[LightSpeed]

there are quite a few flaws in that spec sheet. first is the bus width(384), which ATI will not shift to anytime soon since GDDR5 speeds are on the rise

Secondly, even if the 384bit bus is true, those memory capacities are impossible. 1024/2048 on a 384bit bus? Zz
Third, with the current 40nm process, and the performance scaling of more shaders in this architecture, a change in clockspeed will have much more of an effect than adding 320 shaders. So, they will not try to widen the architecture to accomodate more shaders, achieve not that much more performance, and lower the yields even further. Also 28nm in Q1? ROFL

I bet the 5890 will be a 5870 with boosted clocks. And that will own. End of
