The price differential is quite large between the GTX 570 and GTX 670. What can I expect in terms of performance improvement in a CUDA intensive application?

In Battlefield 3 at 1920x1200 Ultra and 4xMSAA, the GTX 670 offers around a 50% performance improvement over the GTX 570. So, pricing the GTX 570 around $299, a 50% cost increase would put the GTX 670 at about $450, but it's cheaper than that. So the GTX 670 is the better performer as well as the better value from a price per performance standpoint.

In sum, the GTX 670 is without a doubt worth the additional 100 bones over the 570.

the gtx 670 dominates the 570. the gtx 570 has around 480 cuda cores where as the gtx 670 has 1344. :)  that's it

If I'm not mistaken the GTX670 is better than the GTX580, and its a good price for what it is. Nvidia really hit the nail on the head this time, so it seems. (Although $400 for a gpu is still a scary thought for me)

In Anandtech's CUDA test, the GTX 670 was dead even with the GTX 580, and about 11% ahead of the GTX 570.

In the Smalllux test, it went the other way by far. The GTX 570 beat the GTX 670 by 40% (!) The GTX 580 had the GTX 670 beat by over 60%.

I just don't know how any of these tests translate into real world situations is the problem.

what CUDA apps specifically do you have in mind.?


Malmental,

The applications I care about are Adobe Premiere Pro CS6 and Adobe After Effects CS6.

what is direct compute. has this anything to do with gaming i'd really wanna know?????

Nice one malmental - the power of cuda(nvidia) / dc is lost on some :) 

I have both CS 5.5 premier & AF, and yes of course, some functions (not all) are accelerated. I have also been looking at nvidia's 600 series cards for cuda performance. Surprisingly, it would seem cuda implementation within these cards have not been 'fully implemented' - as you can see from the strange dc benchmarks. Unfortunately this is a known fact with this series. nvidia is apparently (if we believe) prepping something new for business use first (soon) then later for our use (a 'bit' longer).

that's a gaming reference you linked, has nothing to do with CUDA apps..


Ahh yeah sorry. I completely ignored the actual question, probably because 99% of the time people ask these questions regarding games, so I had auto-pilot on. My bad.

looking into it, might be later with detailed info for I am on my way home..
what are the prices of each option.?
systems specs and do you also intend to game.?


EVGA GTX 570: around $260 after rebate. Probably falling.
EVGA GTX 670: around $400

System pecs:

CPU: i7-3770
Mobo: something with H77 or z77 chipset
16 Gig RAM
Corsair TX650

If I can save on the card, I might be able to put the money towards 3930K CPU or additional RAM.

and honestly for you I'd be looking at a 3GB GTX 580 as my first choice.


Can my psu support that?

GTX 580 with 3GB seems to start at $490 after rebate. Why do you think it's preferable?

CS6 doesn't use CUDA specifically. It uses openCl. That means you could also use an AMD card if you like.

I've read somewhere (I tried finding the link but couldn't) that AMDs architecture is actually slightly better for GPGPU because of the greater number of stream processors.

Can anyone else verify this?

I've heard that there is a way to get AMD cards working, but I'd want to see verified reports with specific cards first. Of course there is a long history of getting nVidia cards that are not on the list to work.

I would be interested also if anyone can confirm that the AMDs work and are faster. The tests on anandtech suggest that comparably priced AMDs may be faster in some dc tests.

It seems that CS6 supports both CUDA and OpenCL, but not in the same way.

I think one or more of these things has to happen before I invest in a new GPU:

(1) Price of GTX 5-series falls considerably;
(2) There is more clarity about performance of GTX 6-series with Adobe CS6;
(3) Adobe updates CS6 so it uses GPU acceleration with AMD GPUs under WINDOWS (right now openCL support seems to be limited to Apple OS);
(4) I find my GT-240 to be frustratingly slow with i7--not likely to happen since I am upgrading from Q9400!

Thank you for thoughts about GTX 670 and 570, and happy Gaming!
