AMD Radeon HD 7970: Promising Performance, Paper-Launched

Power, Temperature, And Noise Benchmarks

Let’s say that the Radeon HD 7970 has the potential to be an amazing performer. Would it still be worth $550 if its maximum power load were enough to cause blackouts at Candlestick Park during a 49ers game? Fortunately, we don’t have to speculate.

Surprisingly, the 7970 draws less load power than a GeForce GTX 580, while pulling less at idle than a Radeon HD 6970. AMD’s power management advancements should pay dividends amongst our European audience, which has to pay significantly more for electricity than the North American readers.  

Now it’s time to turn our attention to GPU temperatures. We should mention that the GeForce GTX 580 we’re testing with is a Gigabyte GV-N580SO-15I clocked down to reference frequencies and equipped with an aftermarket cooler.

The temperatures are right where we’d expect them to be in comparison to the Radeon HD 6970, a card with a similar TDP.

Finally, let’s have a look at the noise generated by these products. Once again, keep in mind that the GeForce GTX 580 isn’t a reference card, and its aftermarket cooler provides an advantage you’d typically have to pay extra for.

Uh-oh. That’s a significant amount of noise, which gives us our first concerning design-oriented issue seen thus far. I’m almost afraid to mention it, because when Chris Angelini railed the Radeon HD 6990 for its noise problems, he got a lot of negative feedback. But I’m not willing to bury it, so there it is.

Concerned about a possible heat sink seating issue, I took the card apart and put it back together again with fresh thermal paste. Now, AMD doesn’t recommend this because it claims the phase-changing thermal interface material it uses enables a few-degree advantage over normal thermal paste. In light of our negative results, though, we had little to lose by at least trying. In the end, my surgical procedure made no difference, and we recorded the same acoustic output playing through Battlefield 3.  

Unfortunately, AMD’s time frame for this launch didn’t make testing a second card possible. However, we’ll keep our eyes peeled for a replacement and follow-up should our findings change.

    From a gaming standpoint I fail to see where this card finds a home. For 1920x1080 pretty much any card will work, meanwhile at Eyefinity resolutions it's obvious that a single gpu still isn't viable. Perhaps this will be something that people would consider over 2x 6950, but that isn't exactly an ideal setup either. While much of the article was over my head from a technical standpoint, I hope the 7 series addresses microstuttering in crossfire. If so than perhaps 2x 7950 (Assuming a 449$) becomes a viable alternative to 3x 6950 2GB. I was really hoping we'd see the 7970 in at 449, with the 7950 in at 349. Right now I'm failing to see the value in this card.

    Damn, that's a good looking GPU!

    I'll be trolling Newegg for the next couple weeks on the off-chance they pop up before the 9th. A couple in CrossFire could be pretty phenomenal, but it remains to be seen if they maintain the 6900-series scalability.

    Hate to break it to you, but there won't be, unless you celebrate Christmas in mid-January.

    If I ever find someone that will buy me a $500 graphics card for Valentine's Day I'll be proposing on the spot.

    While I have little doubt that 2x of these cards would be very impressive, so would the $1100+ pricetag. I guess coming from the 580 SLI standpoint it might not seem like much, but if you've been considering the $750 ($900 for mobo+psu difference) 3x 6950 route like myself it seems like a major jump.

    Of course this is all just initial reaction towards the earliest of benchmarks. Given awhile to really dig around the new 7xxx, while allowing it to mature from a driver standpoint might make the 3x6950 seem foolhardy.

    WOW!!! I love the conslusion; all of it, which basically is interpretted as "I'm biased towards Nvidia," and trys to say don't buy this card! Has the nerve to mention Kepler as an alternative; right, Kepler, as in 1 year away. The GTX580 just got "Radeon-ed" in it's rear. I'm not biased towards either manufacturer, just love to see and give credit to a team of people with passion, vision, and hardwork come together and put their company back on the map, as is shown here today with AMD's launch of the 7970. It's AMD's version of "Tebow Time!!"
