NVIDIA GF100 & Friends speculation

[chavvdarrr]

any rumors about the name of full Gf104 card?

 

[Mize]

My business trips aren't that boring, that I need to waste my spare time in front of any sort of PC LOL

It's hard to spend 2+ weeks in China without some down time, though I almost never use it for gaming...books and cinema are more common.

Besides GTX460? The full one might be GTX475.

What? So now you are basically retreating and assuming GF104 will be comparatively better than a GTX480?

Say what?

You know the GTX460 will be slower than the GTX465, yet a suitable clocked GF104 might be a better option than a GTX470

Surely theres a mistake, this might be a GF106 or cut down version of it. Sounds more plausible. And with 96 SP's it'll end up being close to GT 240 in size. IMHO GF108 will definitely not have more than 32 SP's.

Maybe this time around, the infamous "8" will not be the same as Ion ub0r-next-gen?

You might be right. Charlie talked some time ago of a GF119 codename.

What if the magic number is 48?

42. Definitely 42.
Less seriously (what could possibly be more serious than 42?), I don't see how Fermi scales to anything not a multiple of 32 unless they spend more engineering resources on it than it's probably worth. As I said in the past (i.e. it wasn't likely then, it's less likely now, but that has never stopped me before!) I think it's more likely they scale the number of TMUs per block of 32 SMs to different multiples of 2.

Resulting in seriously pissed off GTX470 owners no doubt. But who aren't they pissing off these days.

It took a mighty long time for G92 (add metal spins, die shrinks, metal spins again etc.) to go from 112SPs@1.5GHz (8800GT) to 128SPs@>1.8GHz (9800GTX+). Hell they're still selling G92's under the GT330 name today.

Hence the "this is the new 8800GT" lines.. It's not an 8800GT when it comes to performance, yet but it might prove golden for nV later on.

 

[CarstenS]

One possibility would be to simply cut off half of the ALUs, making essentially a half-SM-chip. Much like GT218 probably was (and still is) a one-out-of-three SMs enabled product.

or use 3*16 instead of 2*16

 

[CarstenS]

Sure, but you cannot argue, that it would be easier to just disable 16 out of already existing 32 ALUs (or one out of two lanes) than to use 16 ALUs which aren't there in the first place.

So that could mean also that it has more shader horsepower than we expect? 8800GT had 112 shaders after all, shy from the 128.

So twice the TDP, and +20.6% in 3DMark Vantage...
