[Official] AMD Radeon HD 7950/7970/7990 Owners Thread - Page 701

post #7001 of 38701
Also, just going by some of the stuff I read when the card first released (I was shopping at the time for 570s, so I only read it out of curiosity), the locked shader clocks limit the amount that you can really OC the card. That and the drivers/games that are optimized better for nvidia cards, as others have said.

afaik, the locked shader shouldnt have anything to do with how well the card overclocks.

Anyways, the 680 wasn't as impressive as the leaks were pointing to. What happened to the 40% gain over 7970? rolleyes.gif

Someone asked awhile ago, FC-7970 Backplate will not work with 7950, they have their own backplate which should be available this week from EK's webshop.

Also, the 680 is a butchered GPU. They ripped a large majority of the compute stuff (GPGPU) to get the efficiency, TDP, and temps they wanted (see: 7870 or 560Ti).

in all honesty, amd makes some damn good graphics cards. on the other hand, their drivers are sorely lacking at times and it puts a hurting on performance.

when i had my 2 4870x2's running, i was was having nothing but problems with those drivers. then a friend of mine sent me a link to some forum (cant remember which one) and i found a guy on there that was modding/fixing amd drivers. cant remember the guys name to save my life. but to make a long story short, those drivers he was messing with worked like a charm and from that day on, i never used a driver that he didnt mod.

Don't go overboard guys, the 680 is still a damned fast card. It's the arch nemesis for a reason. thumb.gif

Yes indeed. I'm still sticking by my plan of Xfire Lightnings though biggrin.gif They just need to come out in Aus!

OCing now, running 3DMark11 at 1150 core and it seems good. Hopefully I can push 1200 on stock volts, although I don't know that there's much chance of that! After running 3DMark at 1100 (and getting 500 more points because of it o_0) GPU was at 58C, and VRMs 86C

Ha, nope, display driver stopped responding at 1200. I might leave it at 1150 for now, see what I can do on the mem.

Seems all stable at 1150/1600, and I'm happy with that for now. Going to run Heaven to test, then play some BF3 later and see how I go.

Agreed they did sacrifice those features. Nonetheless as a gaming card it is a lean and mean product, I don't think it kills the HD7970 by any means but it does take ground whilst having advantages in die size and memory size (in terms of the cost of card and the room for price shifting). I don't think this rules out the 7970 but I do think it needs to at least match the RRP of the 680.

As of yet I havent seen any reviews dealing with multi-monitor set-ups (not applicable to me personally) but I would be interested to see if the added VRAM would be a benefit to the 7900s here.

Do we know yet if the gtx680 OCs as well as the 7970? I can see it beating the 7970 @ 925, but @ 1250?

i think it does to a point, then theres a limit to how far it can oc before it requires a hard mod to go any higher. w

They can overclock very well but their vrms could pose a problem with very high clocks 24/7.
