Therefore Nvidia should cater to only them and the fact that the card beats a 7970 in what it was designed to do is still considered a total fail...

Someone had to say it. One huge rep for you Eric thumb.gif

This disappoints me a little bit. Though I most likely won't actually own a card from this generation, it's never good to see any aspect of an architecture go backwards in performance.

It could be that the 680's mid range origins, and certain fundamental mid range design decisions are catching up to it on the compute side. If I recall correctly, GF104/114 had certain compute related components removed, and some compute friendly layout choices changed in favor of a lighter, more graphics friendly design. This could be seen as the natural progression of that concept, but magnified. I imagine that at the outset of GK104 design, Nvidia probably thought that GPGPU performance was non critical in the midrange market that they intended for this chip to end up in, and chose to make a smaller more graphics oriented die.

At least I hope this is the case. I need CUDA performance to keep increasing, and I would like to see Nvidia start contending seriously in OpenCL space as well. I use Cuda for Adobe Premiere CS5, and though that workload doesn't really push my current card much, I hear that After Effects CS6 will be getting massive CUDA acceleration. That could really put a beating on any chip on the market, considering what it does to every CPU ever released.

Or a 7970. wink.gif

Wow such a reputable outlet as the Inquirer must have excellent scientific data from cars put through a rigorous benchmark with an even playing field. Obvious sarcasm is obvious...VIVA LA NVIDIA!

i dont give a **** about them. im in a tech site because I play games. if they make a lot of money like what you say and help humanity then they shouldn't be wasting their times in a tech site arguing about graphics cards to begin with. they should stop wasting their time and make more money

Yeah, guys making millions of dollars a year are buying Geforce gaming-oriented cards to do it... rolleyes.gif

Anyway, this is off-topic. Nobody said that all 680 gpu compute performance sucks, just OpenCL (and even that is still just rumor). This card still has a formidable amount of CUDA which is pretty much the industry standard...

Well, this isn't even surprising at all. It's double precision floating point... something that Nvidia completely neuters on consumer cards. It wouldn't look this bad (or at least I don't think it would) on professional cards relative to AMD's stuff. It's not like 64 bit floating point is even something to worry about as a consumer anyways... if you were, you wouldn't even be looking at the 680 - you'd be looking at professional cards.

Hey, that's what I've been saying the past couple of pages...

It is disappointing how great scientists like Kepler and Fermi were named after such problematic products. frown.gif
