ATI Radeon HD 4000 Series discussion

lol well if it isn't ol' Cadaveca

What happened to your avvy with your old case in it

Life is easier being a nobody than a somebody.

Anyhoo, they have also added 32 TMUs, and though your point is valid, 800 SPs is generally believed to be overkill unless SP efficiency is REALLY bad and they need to do it just to increase performance by significant amount.

As for your point about "what difference is there between 3870 and 4870 if they do that", take a look at the prices, they are almost identical to 3870 and 3850 prices at launch. If they really wanted to launch a 800 SP monster, they would have put the price similar to the GTX 260 at $449 and not $329 and $229. We have heard news that the reason for the low 4850 clock was because ATI does not want the 4850 to beat the 3870 by a large amount otherwise no one would buy the 3870 and that makes sense.

I just don't think ATI can put 800SPs on the same 55nm architecture as the 3800 series.

Perkam

You are missing the point. That die increase has to account for something. TMU's? you mean more cache?


Ok, so we have accounted for 10%-12% of the extra 50%, were's the remaining 38%-40%?

What else in R770 can account for that very large transitor count? 666m transistors increased to 1b transistors...why?





Cost is not something to be considered. We are still living out ATI's legacy...AMD products are not here yet in ATI line-up. This is not ATI anymore, Perkam, so old price models definately do not apply here. I mean really...3870x2 was top-level card...old ATI management would have never made such a silly move...you must rethink strategy here.
