Final Words

When AMD launched the Radeon HD 7970 last month there was a great deal of speculation that the Radeon HD 7950 would be their direct GeForce GTX 580 competitor, and indeed this has proven to be the case. While the 7970 sails past the GTX 580—and AMD has priced it based on that—the 7950 and the GTX 580 are trading blows on a game-by-game basis, similar to what we saw last year in comparing the GTX 500 series and the Radeon HD 6900 series. But when the 7950 wins it wins big, while the same cannot be said of the GTX 580; the only real weakness for the 7950 right now is Battlefield 3, and while that’s an important game it’s but one of several.

Ultimately it’s not a fair fight, not that AMD ever intended it to be one. Outside of a few corner cases the 7950 renders the GTX 580 irrelevant, and while it’s not quite as immense as what the 5850 did to the GTX 285 2 years ago the outcome is much the same. With the 7950 AMD can deliver performance similar to if not better than the GTX 580 while consuming significantly less power and enjoying all the temperature & noise benefits that provides, making it a very attractive card.

On that note the cooling situation makes the launch of the 7950 one of the more unusual high-end product launches in recent history. With high-end cards typically sticking to reference designs for the first phase of their lives the 7950 lineup is going to be much more varied than normal, not only in gaming performance due to factory overclocks but in cooling performance too. While we can speak in absolutes about the gaming performance of the 7950 there is no common thread on cooling performance—it needs to be evaluated on a per-product basis, so it will be important to do your research.

Meanwhile the $450 price tag is unfortunately not very aggressive on AMD’s part, but with their lead in rolling out their new lineup this is to be expected. Given its performance the 7950 only needs to be as cheap as the cheapest GTX 580 and that’s exactly what AMD has done. There will ultimately be a massive price shakeup at the high-end due to 28nm, but this looks like it won’t happen until AMD has some competition at 28nm or 7900 sales slow down significantly.

Finally, what about our retail sample cards, the XFX R7950 Black Edition Double Dissipation and the Sapphire HD 7950 Overclock Edition? These two cards clearly embody the type of variety we’re going to see from AMD’s partners; they have fairly large factory overclocks and large open air coolers, and with these customizations AMD’s partners are hoping to set themselves apart from each other while justifying a higher MSRP in the process.

Overall the Sapphire HD 7950 Overclock Edition is the clear winner among the two cards. While I believe our specific sample is well above the average card due to its extremely low VID, in terms of design Sapphire has clearly done their homework and it shows with an excellent cooler that is ridiculously quiet and equally as cool. The factory overclock isn’t anything that shouldn’t be achievable on your own, but if you’re serious about overclocking the cooler alone would be enough to justify the extra $30.

On the other hand the XFX R7950 Black Edition Double Dissipation ends up being a bummer, particularly compared to its 7970 based sibling. For what an open air cooler can do it’s simply too hot and too loud; the numbers we’re seeing would be acceptable for a blower, but not for an open air cooler. The gaming performance is great thanks to its best in class factory overclock, but this isn’t enough to overlook the obvious cooling troubles.

Wrapping things up, so far we’ve looked at single card performance, but what about CrossFire? Later this week we’ll be looking at 7970 and 7950 CrossFire performance, and what the plethora of open air coolers means for 7950 users. So stay tuned.

    Thanks. It looks like the culprit is the ShareThis widget we use. I'll have our developers look at it in the morning.

    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.

    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...

    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...

    Here is the link for the comparison chart between PowerColor and Sapphire.

    forgot the link

    Thanks a lot! Seems that Sapphire has the upper hand after all, in both temperatures and noise..

    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.
