Sapphire Radeon HD 7790 1GB Dual-X Review

How We Tested

As always, we did our best to deliver a clean set of benchmarks, with each test repeated three times, and an average of those results is what we’re reporting here. In the rare case where performance was inconsistent, we continued repeating the test until we obtained three results that were consistent.

The tests performed are a mixture of custom in-game time demos and manually-played sections, and we use FRAPS to record the average and minimum frame rates. We strive to not only record real-world performance you will actually see, but also present the results in a manner that is easy to digest.


We test at 1,920 x 1,080 (1080p), 2,560 x 1,600 and 5,760 x 1,080. However, for the AMD Radeon HD 7790 1GB, we will be displaying results for sub-£200 cards at the single screen resolutions only, since these are the results which are most relevant. Please also note that the Crysis 2 benchmarks have now been replaced with Crysis 3 ones following our performance analysis of the newer game.
