AMD Radeon HD 7950 Review Feat. Sapphire & XFX: Sewing Up The High-End Market
by Ryan Smith on January 31, 2012 9:02 AM ESTCrysis: Warhead
Kicking things off as always is Crysis: Warhead. It’s no longer the toughest game in our benchmark suite, but it’s still a technically complex game that has proven to be a very consistent benchmark. Thus even 4 years since the release of the original Crysis, “but can it run Crysis?” is still an important question, and the answer continues to be “no.” While we’re closer than ever, full Enthusiast settings at a 60fps is still beyond the grasp of a single-GPU card.
AMD’s first round of driver optimizations have given the 7900 a very solid footing in Crysis, putting the 7950 off to a great start. The 7950 is 19% ahead of the GTX 580 at 2560 and 14% ahead at 1920, putting the card in a comfortable position that for single-GPU cards is second only to the 7970. In spite of Crysis being shader-bound most of the time the 7950 is generally within 15% of the 7970, so it’s doing better than the theoretical performance gap between the two cards would predict. Meanwhile compared to AMD’s last generation offerings it’s not much of a contest: the 7950 is 20-25% ahead.
As for our factory overclocked Sapphire and XFX cards, they further close the gap between the 7950 and 7970. The 12.5% core overclock on these cards puts them between 7% and 10% faster than the stock clocked 7950, with the XFX card edging out the Sapphire due to its memory overclock. These cards do so well here than the reference 7970’s lead is reduced to just 5%.
The minimum framerates in Crysis are also looking good on the 7950, with the 7950 turning in a 10-22% better minimum framerate than the GTX 580 depending on whether we’re talking about 1920 or 2560. As like we saw with the 7970, the biggest lead is at the highest resolutions, which has typically been the case for AMD cards for some time now. The overclocked partner cards add to this, tacking on an extra 5-10% in performance.

Thanks. It looks like the culprit is the ShareThis widget we use. I'll have our developers look at it in the morning.Ananke - Tuesday, January 31, 2012 - link
This is a wonderful but too expensive product for the targeted market niche...It will not gain user base by April to attract software developers away from Kepler...Unless NVidia really executes bad /which they will not-internal source/, AMD will be positioned worthlessly by price/performance. Anyway, I admire AMD and I use their products, just their strategy has been lost recently.gnorgel - Tuesday, January 31, 2012 - link
It seems quite pointless to me to benchmark an OC 7950 vs a stock clocked 7970.Anyone who OCs a 7950 would OC his 7970 too. The interesting question is how these 2 OCed Cards perform against each other - this decides whether the the price difference is worth it or not.

The best way to get performance per dollar is at this website:http://www.videocardbenchmark.net/gpu_list.php
and sort by "Video Card Value". Using this chart, I bought an HD6850 today, to replace my HD4890 (which is also near the top of the chart). It has enogh performance for me. The performance per dollar is dominated by AMD at the moment.

My comment was supposed to be a response to another comment...LuxZg - Wednesday, February 1, 2012 - link
Now all that I wish for is direct comparison between Sapphire card and PowerColor PCS+ version.. Based on techPowerUp's review PowerColor could actually have even better cooling solution (noise/heat) which would really be amazing since Sapphire is already awesome. Make my wish come true Anand! :)And thanks for great review guys and showing off what a nice job AMD & Sapphire did with their new products...

Thanks a lot! Seems that Sapphire has the upper hand after all, in both temperatures and noise..Th-z - Wednesday, February 1, 2012 - link
What GCN is able to do in the future is yet to been seen. They need a software ecosystem to support it, like what CUDA is having. In terms of gaming, aside from lower power consumption, the price isn't very attractive. I can see 7970 command a hefty premium, but the price of 7950 would fail AMD to capture some market share. The price they're trying to undercut is a single-GPU flagship part, which also carries a premium over 570, yet 7950 isn't a flagship part.In terms of gaming performance, 7950 is close to 580, which is close to 6970, yet it costs so much higher than 6970. It would be interesting to see how AMD is going to price their VLIW4 7800 and lower parts, because from the specs, they aren't much faster than 6000 series. This time, we probably won't see good performance jump with similar price points even after a major die shrink (remember they even skipped 32 nm). And I think the unnamed NVIDIA source said they was expecting more from 7970, which I think isn't a bluff, considered their Fermi debacle.
