If you're interested in spending money on a AMD Radeon HD 7970 graphics card, then the Club 3D royalAce is certainly worth considering. It is clearly the fastest Radeon HD 7970 that we've tested until now. It's also the hottest, which somewhat limits its overclocking potential. It's also noisier than average. If you're only interested in performance, then this Radeon HD 7970 royalAce is a good choice. The ASUS HD7970-DC2T-3GD5 is about six degrees cooler, about 10 dB(A) quieter, a little cheaper but also a little slower. See also: How to choose a graphics card.
After the introduction of the nVidia GeForce GTX 680 by Nvidia, AMD needed to come up with a graphics card that's able to compete. In late June, it launched the Radeon HD 7970 GHz Edition, a faster version of the 7970. Club 3D is one of the first manufacturers to launch a non-reference version of this particular edition of the HD 7970. The boffins over at Hardware.Info tested this card to see whether it is any good. Click here for the full review.
The Radeon HD 7970 GHz Edition actually is a rather pointless graphics cards, as most manufacturers already have an overclocked version of the Radeon HD 7970 in their line-up. There's really not much point in releasing one. Still, GHz Edition cards are slowly but surely entering the market. The royalAce by Club 3D is one example of such a new card.
However, they've stepped it up a notch in terms of clock frequency compared to the reference GHz Edition card AMD produced. It's actually a slightly overclocked version of an overclocked Radeon HD 7970, with a standard GPU clock speed of 1050 MHz instead of the 1000 MHz on the standard GHz Edition, and a Turbo of 1100 MHz instead of 1050 MHz. This makes it the HD 7970 with the highest standard clock frequency Hardware.Info has ever tested.
As it turns out, the Club 3D royalAce is indeed on average the fastest card so far, which isn't very surprising given the high clock frequencies. This speed also has a downside though, and that has to do with noise. The royalAce produces quite a lot of that. This also was to be expected if you consider that higher clock speeds generate more heat, which in turn has to be dissipated one way or another.
Hardware.Info concludes that the Club 3D Radeon HD 7970 royalAce certainly is a card worth considering if you're in the market for speed and speed alone, and aren't too bothered about heat and noise production. If you do care about those things, then it may be wise to look a little further.
