GM200/Titan X announced with slow DP

[Picao84]

Like I speculated in the old forum, Big Maxwell, unlike Big Kepler/Fermi, is not strong in DP: only 0,2 TFlops.
One more for the record, following my speculation that Maxwell would be most if not all done in 28nm, several months before the release of GM204. As usual, I was faced at the time with some fierce opposition to this idea, never mind how many arguments and facts I thrown at it.

On a side note, the keynote is very very interesting. Lots of information about Pascal and performance estimates: 10x faster than Maxwell!!

You are spouting bullshit here, Picao84!

You cannot infer GM200's true FP64 capabilities from Titan X, since they are artificially limited to 1/32 of the GPU's true capabilities in Titan X, just like regular consumer geforces.

It does make you wonder precisely what the point of Titan is nowadays though, they used to limit Titan to 1/3 the true fp64 rate and tout the card as something a small/home developer would like since you could use it like a slower Quadro/Tesla or a geforce. The 1/32 fp64 rate makes it no better than any other garden variety geforce for CUDA though.

I guess the true purpose of Titan nowadays is to separate fools from their money (just like Intels x99).

*sigh* No I'm not. Maximum of GM200 is really 1:32 DP. Before lashing out at me go see the reviews with technical information on them like Anandtech. Why do you think they are speculating GK110 was the last time we have seen a big nVIDIA GPU share gaming and DP capabilities? Even nVIDIA themselves said that for compute there is GK210. I wont quote now cause I'm on the mobile phone, but if you don't believe me go check for yourself. Plus nVIDIA is now betting heavily in deep neutral networks, which don't need FP64 and are happy with FP16 and FP32. Those are in fact big news for gaming as well. Less space occupied by DP that can be b used for gaming functions. GM200 is already a sign off that shift.

2 970s at $330 = $660.  Titan X = $999.  Tom Cruise Laughing.gif

Yeah, what I was thinking. Sick must be some kind of balla if >$300 difference is "wouldn't cost much less."



I'm loving everything I'm seeing for Titan X except the price. Is peaking my interest more towards GTX 980 Ti, whatever that may be, but frankly at this point SLI 970/CFX 290's looks like might be the better deal until we see what 390X can/can't do.

In the last two year the chips went:
GF110 >> GK110 >> GM200
$550 >> $700 >> $1000

It makes me sad :( My poor wallet.

Yeah.. But nothing changes if nVIDIA has a monopoly right? Right? *rolls eyes* Happening in front of our eyes but still some deny it. Incredible.
