Multi-GPU Results: Tomb Raider
A pair of GeForce GTX 770s lands between the 780s and AMD’s Radeon HD 7990. Though, when it comes to average frame rates, the 770s, 7990, and GeForce GTX 680s are all pretty much identical.
When we spread frame rates out over time, the second-to-last-place GeForce GTX 690 actually appears more consistent than the Radeon HD 7990, which spikes as high as 110 FPS, but then drops as low as 20. The GeForce GTX 770s we’re benchmarking today peak just north of 100 FPS and don’t drop any lower than 40, yielding what I’d consider to be a superior experience that should reflect in the frame time variance numbers.
And there’s the smoking gun. The variance you experience between the time it takes to render one frame and then the next does matter, as we all know. Two GeForce GTX 770s, at worst, are in the 2 ms range of difference. The pace between frames is even, so even when frame rate drops, frames are being delivered at a consistent interval. The Radeon HD 7990’s average is higher at 2.2 ms, and at worst, variance spikes at almost 20 ms.

Amazing - this oughtta shake up the market!Reply
CF 7970s > AllReply
Thanks for the article.Reply
Kind of an expected performance increase. Seeing overclocked GTX 680 review was conclusive enough unless you've never seen one. Never expected this card to be getting the Smart Buy award though to be completely honest.
Hey, how about another title for the review?
- GTX 680 Gets a New Cooler, BIOS Update and Price Drop! -
No? I'll think of a better one...
the fact that every single site is comparing nvidia's next-gen stuff with AMD's current gen stuff kinda sickens me. don't start throwing around "Nvidia's got this gen in the bag" till we see what AMD comes up with. they've had what, 1 1/2, 2 years? I'm hoping for GCN 2 and a die shrink on a new architecture.Reply
EzioAsNever expected this card to be getting the Smart Buy award though to be completely honest.Better power consumption than 7970GE.Reply
Less noise than 7970GE.
Runs cooler than 7970GE.
Same FPS as 7970GE.
$50 less cost.
Yeah indeed, why to get the Smart Buy award I wonder...
That is some aggressive pricing right there! LOLReply
Finally, a card that will drop the prices of hd7000 and gtx600 GPUs.Reply
Well in the UK the GTX770 is still more expensive than the HD7970.Reply
10884687 said:When you factor in the 4 games that come with the HD7970 GHz Edition, it is still cheaper than the GTX 770. I find it odd that nVidia had over a year to come up with something to beat AMD in single GPU performance at this price point but failed to deliver.
Yes, there is a bit of power savings. Yes, multi-GPU performance is better. But, that is nothing new. I also wouldn't expect future drivers to deliver much in the way of performance improvements since this card is essentially a GTX 680 v2.
Ultimately, I expected more from nVidia. Yes, this is a polished card out of the gate. But I'm not sure the release of this card will affect AMDs bottom line as things currently stand, performance wise.
Agreed. Sapphire 7970 Ghz ftw <3
None of Nvidia's partners are using the reference cooler so this is just a scam to get better turbo clock speeds and good scores on quiet and cool operation. You've been had Chris and now you've spread Nvidia's lies to your readership.Reply
