No, Cipher, Vulpes is correct in his information there. The Geforce 600 series is nowhere near the Radon HD 7000 series in GPGPU performance. It's actually
very bad at GPGPU.
This is old news
http://www.theinquir...870-gpu-compute
It varies from test to test of course
http://www.anandtech...x-680-review/17
But generally speaking, that last test by Anandtech was the only one in which even the 680 managed to significantly beat the 7970
or even its predecessor, the 580! (and don't forget to include the above article as yet another failed test). Not only does the 680 fail to generally overcome the 7970 in GPGPU, and get beaten
savagely when it does get beaten, but that article mentions that it couldn't even run some of their GPGPU tests! Given the margins and frequency of wins/losses, I might be willing to stick the 600 series next to the 500 series, and below the 7000 series in GPGPU, but given that last fact, I'm not even inclined to be that charitable.
Expanding our sample a little further, here are more tests:
http://www.brightsid...e.aspx?pageid=4
On that page, compared to the 7970, the 680 loses 8 of 10 tests if we count the two performance measures in each separately (which we shoudl; they measure two different things), and loses 5 of them very, very badly, as in, the 7970 is multiple 680s worth of performance. Of the two it wins, one is nearly a tie anyways, while it scores only one notable victory in 10 tests (admittedly doing very well there, but just the same...).
There was one further test in that review where the 680 could score some points, albiet it questionable, here:
http://www.brightsid...e.aspx?pageid=6
Clearly the test is rather dysfunctional if "hardware accelarated" performance is worse than CPU-only, but finding tests where the 680 doesn't fail abjectly isn't easy, so I figured it was worth a mention, even if it doesn't remotely change the overall picture.
So no, Vulpes was not being a fanboy, and his information was completely correct. The 680 is a fantastic gaming card, but it performs miserably in GPGPU, just like he said.
I understand that you want accurate information given here, but you should research other posters' claims before you declare them wrong.
I guess the clarification never hurts though. Now the OP has citations
