The official GT300/Fermi Thread

[LiquidReactor]

GT300 is not going to be faster than the 5870 by such a negligible amount that a 5890 would pull ahead. There will be a 5870X2, but then again there will also be a dual GPU GT300.

If Nvidia is already on planning on making a dual G300 die gpu solution this should indicate that a single g300 will not completely obliterate hd 5870 in real world gaming. I'm guessing average 15-20% with highs of 30% faster in some games.

Also 40nM and 550mm^2 die size?
G300 x2 dual die solution will either have to be dual pcb or a single pcb thats longer then even the new 5870x2. GTX295v2 (single pcb) was hard enough despite the die shrink going to 55nm (576mm^2 >>> ~452mm^2). How nvidia is going to put two 550mm^2 dies together to form a single gpu solution is not something I want to think about on a technical level.

Somehow I don't think a 5890 is ATi's answer to fermi, I'd think they're more hopeful for the 5870x2 to handle that task than the 5890.

5870 reference pcb is pretty much designed with a higher power draw (higher clocked) chip in mind.
