It makes absolutely no sense to say heavy underclock. If each and every 7950 could reach what some members of OCN think they can, AMD would be releasing cards with 1050-1100 mhz boost instead of 925. In which case, no 12.11 drivers would have been needed to even the playing field and AMD would have been winning benches right from the getgo.


It makes no sense to you because you're going to argue about something no matter what.


Cayman 6950 was clocked silly low as well? Omg, why would they do that? If you have to ask you need another hobby.

^this. clock for clock HD 7950 is 3 - 6% slower than HD 7970. the same relation applies for GTX 670 and GTX 680. HD 7970 Ghz (1050 Mhz) beats a GTX 680(1058 - 1110 Mhz) by around an average of 7% across a wide range of games. Understand that is an average. So when AMD wins in a game like BF3 its even more faster, at 1080p by 12 - 15%. It would need a 1200 Mhz GTX 680 to match a HD 7970 Ghz at 1050 Mhz. Same for HD 7950 against GTX 670.

Suffice to say in the majority of the games a HD 79x0(1200 Mhz) will be faster than its Nvidia counterpart at 1350 Mhz. 1200 mhz is quite achievable on the HD 7950 boost models which run at 925 mhz and come with a higher stock voltage. these cards run at 1.1 Ghz at stock voltage. They can hit 1200 Mhz with voltage tweaking.

I only wish that AMD could offer some level of competition. It's so consistently inferior that nVidia can release its budget chips to compete with AMDs enthusiast products and still end up dominating.. even at price/performance. Hell, AMD doesn't even have noise levels/power consumption anymore. Funny that this never gets mentioned, since it was all they could talk about when Fermi was out.

Aren't the boost editions all volt locked? Well, unless you use a modded BIOS I guess

GTX 680 was the best Nvidia could release in Q1 2012. It beat the competition at stock performance and price. its not their budget chip when it was priced at 500. get over that crap. if Nvidia could have released a GK100 chip they would definitely have done it. But it was not possible. Could AMD have done better with launch driver performance. definitely. But that does not mean you come here telling that HD 7970 Ghz does not offer competition to GTX 680. thats ridiculous. Right now there is no competition for the fastest card. AMD had the fastest single GPU card since July with 12.7 beta and HD 7970 Ghz. It was still close then. Now with 12.11 its not.

voltage locking seems to be based on vendor and specific PCB versions. some are. but not all. there are sapphire hd 7950 boost users who have said they were able to control voltage.

^^adding to the above...

Reference design as dictated by AMD, DOES NOT INCLUDE VOLTAGE LOCKING. You can thank your AIB for that decision.

A lot of negativity and personal attacks. Mostly from the AMD sides. Hmm. I really hope the 780 is amazing, and destroys everything and anything around it, or even glancing at it. Maybe the forums will be peaceful again.

Brag all you want about AMD beating Nvidia right now, cause the Facts are that was not the case just three months ago. AMD finally jumps ahead of nvidia for a short period and you guys act like they are a gift from god. And AMD has always been supreme. rolleyes.gif

I find this halarious, because nVidia was king from until they got the 680 out the door to until the 7970 Ghz was out the door. Besides that, this entire year was owned by AMD. tongue.gif

Heck, the 7970 Ghz was just AMD laughing at nVidia and flicking them in the nose, all they did was raise the clocks a little bit.
