I've been at Official AMD presentation week ago, and they had no information about R7xx GPU's specifications, not even a theoretical product roadmap.Quote:

When will it be released ??
I want the 4870 X2 :D
I meant multicore as in VSA-100 or MCM, not traditional gpu-like "multicore". (Btw, the core has a lot of other stuff than just stream processors.)Quote:

Or you can mod a 3870 and have moster clocks for everyday use if you want ATI :DQuote:

so no shared frame buffer? too bad...
...and "they" said it wouldnt happen :)Quote:
so at the moment a two chip solution is the way to go.
harhar
despite the usual multi gpu driver prob's a fair few games seem to benfit from crossfireonacard multigpu.
but too exe for me, so 4870 i spose vs wottever nvidia pull out of their hat/s. another mini upgrade from 8800gt...
I'm sure if they are truly planning on releasing another X2 card that drivers will mature...Quote:

:nuts:
and almost 40% increase over the 8800Ultra. too good to be true :D
a little comparison to 8800 series memory bandwiths:
HD 4000 Pricing :
Radeon HD 4870 X2 (2 x RV770) -> частоты 1050/3600 МГц, 1 Гб или 2 Гб GDDR-5, TDP=250 Вт, $499;
Radeon HD 4870 (RV770) -> частоты 1050/4400 МГц, 1 Гб GDDR-5, TDP=150 Вт, $299;
Radeon HD 4850 (RV770) -> частоты 850/3600 МГц, 512 Mб GDDR-5, TDP=120 Вт, $249;
Radeon HD 4670 (RV740) -> частоты 1000/2400 МГц, 512 Mб GDDR-4, TDP=100 Вт, $149;
Radeon HD 4650 (RV740) -> частоты 800/2000 МГц, 256 Mб GDDR-4, TDP=80 Вт, $129;
Radeon HD 4470 (RV710) -> частоты 900/1600 МГц, 256 Mб GDDR-3, TDP=50 Вт, $79;
Radeon HD 4450 (RV710) -> частоты 700/1000 МГц, 128 Mб GDDR-2, TDP=30 Вт, $59.

Radeon HD 4650 (RV740) -> частоты 800/2000 МГц, 256 Mб GDDR-4, TDP=80 Вт, $129;
this one is against 9600gt if rumors are true
The card, when it works flawessly, is a beast. But in almost every game, the drivers suck a$$ with something. In one game is with text corruption, in other is second core not working (basically CF not working) and in others they simply make the game totally unplayable, with half of a single 3870's framerate.Quote:

Dude, this is ATI, and CF drivers, I think you should reconsider that claim. They are good in some areas, but when it comes to fix something with the drivers... well, good luck.
Why would 4870 be $300 and the x2 be only $500? It should be at least 600.Quote:

They are not the MSRP, they are target prices. Just for orientation or how to put it. AMD/ATI wants to keep the cards affordable and the prices are in no way what you should expect the retail prices to be, but from what I know AMD aims to stick below these prices.
But, I mean, we're four months from the launch, it's still a long way to go.

There are a couple of things that actually doesn't add up for me in the information hartware.net has posted. One of them being the ROPs. IF RV770 is suppose to have a MCM design and ATI has doubled the amount of TMUs, logically the amount of ROPs should double too.Quote:
