AMD Radeon HD 7950 Review Feat. Sapphire & XFX: Sewing Up The High-End Market
by Ryan Smith on January 31, 2012 9:02 AM ESTOverclocking: Game & Compute Performance
We’ll keep the commentary thin here, but overall the overclocked performance of the 7950s looks very good. The XFX 7950 BEDD has the lead among the 7950s due to its slightly higher overclock of 1050MHz, while the 7950s as a whole enjoy anywhere between a 2% to 10% lead over the 7970. It’s clear that if you want a 7970’s gaming performance at a slightly lower price then the 7950 can deliver on that through overclocking—and there seems to be little reason not to pursue it—but you’re going to have to pay the price on power consumption to get there.
The compute performance gap on the other hand can’t be closed quite as easily. Overclocking can help, but if you need a 7900 series card for a heavy compute workload there’s no making up for the lost CU array; you’d still need a 7970.

I don't think Anandtech is read by the "average user"... I would assume mostly gamers, enthusiasts, and IT pros here. Besides who buys 1920x1080 monitors? If the monitor isn't 1920x1200 or higher its not worth buying.Ryan Smith - Tuesday, January 31, 2012 - link
Hi poohbear;When drawing out the tests for the current GPU benchmark suite we debated between 1920x1200 and 1920x1080. Ultimately it was decided that 1920x1200 would be more useful for our needs and that 1920x1080 would be unnecessary; 1920x1080 is only slightly lower in resolution, so our 1920x1200 numbers are only slightly worse in performance than they would be with 1920x1080. The two should be treated as the same, as there's generally not nearly enough of a difference to matter.

It seems there's two choices for 7950, either a 450€+ custom OC card or a "v2" reference cheapo-PCB cards that go for 400€ in Europe. It would certainly be interesting to get a detailed look at how much of a difference that makes. To me those "v2" cards look a bit too nerfed in terms of VRM and cooling.IMO 7950 is priced accordingly and is no question better than a GTX 580 by any metric really. That's enough to justify a similar price. It's up to Nvidia to drop the GTX 580 price to compete, but I doubt they'll do that, and instead wait for GK104 to save the day. If it is a success we could see prices drop fast in the high end, but Nvidia isn't known for its low pricing, and neither does it have any need to try grab market share by undercutting its profits. There's a good cap between 7800 and 7900 and they could just occupy it with a GK104 and call it a day, until they get their big chip ready.

That Sapphire cooler looks pretty much like their Dirt3 Edition 6950s one. A slightly different plastic shroud but fan's and underlay seem mostly the same.. atleast in the picture views I've seen.gamoniac - Tuesday, January 31, 2012 - link
I found that, in IE 9, I have to click on the "Back" button on the browser six to seven times to actually go back to the main page. Taking a closer look at it, I noticed there are a bunch of "Share this Page" history item between this page (Ryan's HD7950 Review) and the main page that took place without my knowledge. Would this be a site bug or a advertisement bug?Ryan Smith - Tuesday, January 31, 2012 - link
To the best of my knowledge (please keep in mind that I'm not responsible for site development), that's not something the site should be doing. In which case it could very well be an ad bug. If it continues to happen you should be able to use the IE9 developer tools (built-in, F12), to try to narrow down what exactly it is you're seeing.gamoniac - Tuesday, January 31, 2012 - link
Without spending too much time on it, I can see that there were a bunch of frame navigation caused by sharethis.com, which I think is the likely culprit. I am able to reproduce this issue on two separate Win7 SP1 machines; one of them is clean with almost installed except for the usual PDF reader and some benchmarking tools.Check out these three images I uploaded:

Good luck.
