AMD Radeon HD 7770 and 7750 GPU Reviews
Performance Summary: We saw a distinct, near constant performance trend throughout all of our testing with the Radeon HD 7700 series cards. The Radeon HD 7770 GHz Edition offered good performance in all of our tests that was typically higher than the previous-generation Radeon HD 6790. The Radeon HD 7770 GHz Edition was also faster than the NVIDIA GeForce GTX 550 Ti, but it trailed the GeForce GTX 560, sometimes by a fairly large margin.
The Radeon HD 7750’s performance was also good considering its lower-price and more modest specifications, but its performance was typically lower than the GeForce GTX 550 Ti’s. It did, however, clearly outpace the previous-generation Radeon HD 6670.

AMD’s suggested pricing for the Radeon HD 7770 GHz Edition will start at $159, while the Radeon HD 7750’s will be priced as low as $109. Both should be available immediately. All things considered, those prices are not bad, but as was the case with the Radeon HD 7900 series, we wish AMD was a bit more aggressive. As of today, the GeForce GTX 550 Ti can be had for about $115 to $130 (or lower if you factor in mail in rebates). Also, NVIDIA's GeForce GTX 560 can be found for about $169 to 189. Technically speaking, looking back at the performance, AMD has priced the Radeon HD 7700 series just right—the Radeon HD 7750 is slightly cheaper than the GeForce GTX 550 Ti and the Radeon HD 7770 GHz Edition is somewhat more affordable than the GTX 560. But as the numbers have shown, for a relatively small additional investment, the GeForce GTX 560 offers much more performance than the Radeon HD 7770. Although it wasn’t a clean sweep, generally speaking, the GeForce GTX 550 Ti offers more performance than the 7750 for few extra bucks as well.
There are other factors to consider beyond price / performance though. The Radeon HD 7700 series cards have more flexible output configurations with Eyefinity support, PCIe 3.0 support, discrete digital multi-point audio, and the cards consume less power too. All told, the Radeon HD 7700 series cards look solid at their respective price points and are certainly worthy of consideration if you’re in the market for an affordable GPU.
