3 different 770!

EVGA SC maxed at 1200 .....Gigabyte 1300 and the lightning i have now goes well past over 1350 but i need better cooling than stock so i have it 1300 /7800

my evga 680 did 1200/7k


not all cards get crazy OC and for people like me on air ....we might never see those numbers!

Very good point. Each chip oc differently. Its great to see Giga do well! +1

I thought you knew better than to trust what AMD fans have to say... wink.gif

something doesn't seem right with their review, that 7970 shouldn't be getting the same FPS as those other cards with an OC that high. Is he sure it's completely stable? Could have negative overclocking scaling due to an unstable OC. He was lucky to get a Gigabyte Card that isn't voltage locked, they would sell so many more of those cards if they continued to allow it.

interesting note is that the card seems to be on par with a stock GTX780 in all those tests.

Its the same architecture, it scales exactly the same. Take a look at hardocp titan oc review. A 2/3 ratio is what it is. Titan may scale ever so slightly better because of the mem bandwidth but it is essentially the same.

I'm actually quite surprised the 7970 didn't pull away. 1275 / 1700 is NOT a common overclock on these cards. Nvidia drivers must have brought some improvements because seeing two 680s with average overclocks hang with a highly overclocked 7970 is surprising to say the least.
post #36 of 41
You guys have a point. Seen quite few 7970 vs. 680 comparisons where 7970 with same or slightly less clocks performing better in majority of the applications.

Wow! Guru3D sample achieved almost identical overclock: http://www.guru3d.com/articles_pages/msi_geforce_gtx_770_lightning_review,25.html

A ton of 770 cards are getting at least 1290mhz, hardocp just had bad luck i guess. The extra voltage helps get the average oc that high over the 680s. I mean head into the 770 thread and nearly everyone has 1300mhz. I just wish nvidia gave us a little more voltage but a $400 680 is a treat anyways.

pretty bad luck

Tomshardware's 3 770's from Palit, MSI, & Gigabyte all hit roughly 1300mhz
http://media.bestofmicro.com/9/M/386554/original/Overclocking-03.png

Anantech's wasn't as good, but got their memory to OC to 8ghz!

The Guru3d's first 770 review was looking at a 1250~1293 MHz boost. It's all pretty temperature based, that's where the aftermarket coolers come in smile.gif

Results are a bit weird, not sure who to believe. According to Linus, a 1100/1575MHz 7970 easily beats the reference GTX680 @ +150/220MHz overclock @1440p (not sure what this means in regards of actual clock speeds, but I would guess 1200 something/6500ish ?)

Nvidia´s latest drivers either gave a huge boost, or their 7970 was unstable ?
