ATI Radeon HD 4000 Series discussion

No its about the lack of texture power, doesn't have much to do with AA not being done in the shaders. With double the texture power and double the Z rate, hopefully it should be enough for modern games with max detail. But something tells me if the 800 number is true, we'll be seeing 40 TMUs rather than 32 (same 4:1 ratio)

LoL. You mis-understand, really. TMU's are TEXTURE MEMORY UNITS...cache...

The real problem with R670 is AA implementation. If they fix that, they can get away with 24 TMUs, although this is truly dependant on how many shaders there are...the number of shaders will dictate the number of TMUs.

Helmore, while I partially agree with you, it does not see mto make much sense that AF was a big problem. 16xAF @ 2560x1600 is not a show-stopper. AA WILL make an app unplayable, so while texture filtering and z-ops were a bit anemic, they weren't the real problem.

AA in shaders is essentailly the future, yes. When we get 4xMSAA standard...but that's still a couple of gens off yet...more likely to appear the same time as raytracing...

So ATI had a foray into it, didn't work well for them, but i think they understand the problems they are facing. Doesn't mean they have to beat the dead horse...
