Like the GTX460, will the GTX470 be on a 256-bit memory bus and hence have only 1gb of vram (EDIT: I don't mean multiples of 1gb...I mean like what the GTX470 currently has with a 320-bit interface)? I have read that the 475 will be faster than the 470 but will a vram limitation come into play?

Considering the 475 will likely have less CUDA cores, and lower tesselation capabilities, will it actually perform worse in tesselation heavy games? Or will some other factor be overriding in those games?

Considering people are making 2GB GTX460s, a GF104 based GTX475 with 256-bit bus could also have 2GB.

I edited to be more clear. I mean more than a 256-bit bus (ie. 320-bit on the 470)...not multiples of 1gb like they are doing with the 460s. Is it going to be like the GTX460 768-->GTX460 1gb where the memory interface was increased?

It depends on how heavy the tesselation is to be honest. I doubt any game manufacturer is going to make a setting in a game that sinks most modern GPU's, otherwise what's the point? If the GTX 470 (and 480?) are soon to be EOL, you'll probably see game designers cater to what's available. Metro 2033 is the way it is (some would say needlessly) because it was supposed to sell some GTX 470's and 480's. My $0.02.

As far as VRAM limitations go, you might see some issues at higher resolutions (2560x1200+) in SLI. I don't think you'll see limitations with a single card simply because the GPU lacks the horsepower to use up that amount of RAM in 99% of situations.

Not if it uses a GF104 chip, 256bit bus is as large as that chip does.

gtx 475 on gf 104 is complete speculation atm. I would oc your gtx 460 pretty hard before looking at such a small step up anyway.

I am not sure what to take away from your statement here. GTX480 handily beats 5870 in almost every single DX11 game out right now (Other than BF:BC2) STALKER: CoP, Metro 2033, Dirt 2, Battleforge. So I don't understand how Metro 2033 was made to sell more GTX470/480 cards. Fermi just performs better at the moment with DX11 effects (Depth of Field, High Ambient Occlusion, etc.).

This is all speculation, but....

A fully unlocked GF104 could end up being called a gt470 or gts470 if it's sometimes but not quite as fast as a gtx470. Or it may end up being a gt475 because it's faster than a gtx470 but Nvidia is bound to refresh gf100 and have several derivatives again (gtx485 and gtx475).

But, based purely on speculation and theoretical speeds, 384 cores is 14 percent more than the 336 cores a gtx460 has and if they clock a fully unlocked gf104 100mhz higher like the gtx480 is over a gtx470, that would be a 14.8 percent core increase. So you have 14 percent more cores, and all cores going 15 percent faster ----- we are looking at a theoretical increase of > 30 percent in speed, which would THEORETICALLY be faster than a gtx470. And I think this is all within reason to believe it as a very plausible scenario.

Are percent signs not working displaying properly for anyone else?

I would hope it did since it came out 7 months after it.

you mean like this %?

yeah, I just mentioned that in another thread. weird.

even more weird, when you put a ? after it you get the proper display. see %?


reedit: ok, even more weird. I just typed a % sign, it worked, then I typed another one and it didn't PLUS the original one is messed up. WTF???
