[The Inquirer] Nvidia's GTX680 gets thrashed by AMD's mid-range Radeon HD 7870 in GPU compute

WE'VE HEARD REPORTS about how the upcoming Nvidia GTX680, the very first Kepler 'GK104' GPU will beat all and sundry in everything, including AMD's top of the range Radeon HD 7970, despite the latter's new GCN architecture and 50 per cent wider memory buses and memory capacity.

Wow! The claim of beating the HD7970 goes right into the thin air, it seems. Nvidia's new GPU is beaten by the Radeon HD 7970 by an order of magnitude here in double precision floating-point, as well as nearly twice in ordinary single precision floating point. One is speechless here. Even the Radeon HD 7870 with its restricted double precision floating-point still outperforms the GTX680 by a noticeable margin in this department, as you can see here. Only the Radeon HD 7850 is substantially slower.

I'm confused now, what about the benches we saw on Tom's Hardware?

Nvidia had to give up something in order to achieve all of that gaming performance.

It's always a balancing act.

Those benches on Tom's confirm that OpenCL performance is weaker compared to AMD's lineup.

Too bad the next blockbuster game isn't GPU Compute. We need real reviews.

This. dp FLOPS  has never been a strong suit in Geforce cards. For example, consumer Geforce Fermi cards have 1/4 the double precision compared to its Tesla and Quadros counterparts.

For gamers, this doesn't matter. For the professional market, Compute power is all that matters. The more of it there is, the faster things render, and the faster work gets finished.

That means that without GK110, AMD may have just stolen a big chunk of the professional market where nvidia has traditionally dominated. I wouldn't want to be the guy that has to explain to Jen-Hsun Huang about how they just dominated in one market and alienated another one. That's bad for business.

Didn't Nvidia said GTX 680 a mid range? Guess not if the 680 priced same as AMD and AMD performances go beyond.
