ATI Radeon HD 4000 Series discussion

100% more TMUs in a faster clock.
50% more SP´s in a much faster clock.
Larger caches and new tweaks.

So everything is possible. Is a matter of waiting.

One HD 3870 makes 11K in 3dmark 2006. Going to 18K isn´t at all 100% improvement, but rather 60% improvement witch is possible and not impossible.

Its more then just a change in TMU's and SP's, we have to look at the sheer core speeds we are dealing with here.

From what I have seen the HD 4000 will be buit more like Nvidia cards when it comes to the split between core clock and shader clock.

That means that the top of the line 4870 with its core clock of 1050mhz, the shaders would be running at 2625mhz, which is simply insane. (the diffrence between core and shaders on nvidia cards run around 2.5 times the core, so I just used that number)

Then take in to effect the added memory bandwith of GDDR5, as well as the tweaks to the core and the AA fix, a 100% improvement seems possable, maybe not without AA, but I could see a 100% improvement with AA on under high resolutions.

Add to that the fact CFX works and Quad SLI simply does not (Nivida fan boys don't hunt me down, I have seen my room mate trying to get his 2 9800GX2's to work), ATI could find it's self in a very good place in 2008. And we as consumers are in a good place too, cheap killer video cards... and the idea of 2 4870X2's in CFX make me feel all warm and fuzzy inside.
