GTX 680 SLI vs 7970 Crossfire - *Overclocked* - Tweaktown Comparison  

post #1 of 26
Thread Starter 
So I went out of my way to tabulate these results comparing an SLI setup with two Palit GTX 680's @ 1150-1200 mhz turbo with 1650 Mhz memory, with a Crossfire setup with two MSI Lightnings 7970 @ 1200 Mhz clock / 1500 Mhz memory.


Tweaktown Review Comparison



150




Palit GTX 680 SLI @ 1150-1200 Mhz max Turbo / 1650 Mhz GDDR5 Memory - Link

MSI Lightning 7970 Crossfire @ 1200 Mhz / 1500 Mhz GDDR5 Memory - Link



Setup:


296


Results:



251


WINNER: Nvidia

NVIDIA : 100.98 % Performance
AMD : 100% Performance


---

Results :

Best Game for Each Removed - (AVP : AMD / MAFIA II : Nvidia)


376




WINNER: AMD

NVIDIA : 98.63% Performance
AMD : 100.00% Performance


It seems like Performance is within error across these tests. The 7970 has a slight, average 50 Mhz, clock advantage, while the GTX 680 has a ~150 Mhz (600 Mhz ) memory clock advantage, otherwise the setups are identical.

EDIT: It is interesting to see that DIRT 3 performance goes to AMD, and Metro 2033 performance goes to Nvidia, the opposite of what is found with only a single card comparison between the GTX 680 and the 7970.

---

Also its nice to see that Factory OCd 7970s are finally coming out that run @ stock 1150/1500 Mhz and OC to 1300/1920 Mhz on the stock air cooler.

There is no difference between that performance unless you're a robot.

Each has its strengths and weaknesses, but averaged they become neck and neck. I would love to see a list at least five times as large, to show how close they really are! thumb.gif

You cannot go wrong with either. Amd needs to match price though!

THIS, the single best reason atm for grabbing a 680 over the 7970 is that you can get it cheaper, tho alot of places are raising the 680 in price. They will probally be the exact same price making it a really difficult choice for us people on the fence tongue.gif

After the price drop of the 7970's, I'd have to say the 7970's are the clear winner here thumb.gif

$900-$940 for CFX vs $1000-$1050 for SLI. Great review. +Rep for you! biggrin.gif

I think these are both awesome cards. After moving from crossfire 6950's to a GTX 680, the stability of Nvidia drivers are like night and day. Even running a single 6950, I used to get regular crashes playing games or switching from Windows to BF3 and back again. With my GTX 680, I have only crashed (oddly enough) using GPU tool which isn't a big deal at all. I don't know if I'll go back to AMD unless they release a far superior card at a cheaper price, the stability is worth about $100 to me. FWIW, I probably won't ever run a dual gpu setup either.

How has the experience been stability wise for you 7970 owners?

Does anyone know if msi will bring the twin frozer 4 cooler to the gtx 680?....

Under water, 7970 is totally overkill. 680 doesn't overclock that much, and given the fact that here the 7970 is 60€ cheaper, no doubt I'm buying the 7970 and an EK block thumb.gif

680 doesn't OC much? Are you on drugs they had the core up to 1800 MHz how is that not much. Seriously do research before you start spouting off at the mouth.
