The following gaming benchmarks have been conducted using a discrete graphics card, in this case the GeForce GTX 580, so we can see how the processors compare when teamed with a high-end GPU.
When testing Dirt 3, the A10-5800K matched the i3-3220, Phenom II X4 980 and Core i5-750 at 75fps.
In The Witcher 2, the A10-5800K was 1fps faster than the A8-3850 while being 3fps slower than the Core i3-3220 and Phenom II X4 980.
Despite looking strong in Bad Company 2, the A10-5800K was only able to match the performance of the A8-3850 with an average of 88fps.
Civilization V is a CPU-dependent game, so we saw quite a large variation in the results. The A10-5800K averaged 91fps, or 26% faster than the A8-3850 as well as 14% faster than the Phenom II X4 980. However, it was also 7% slower than the i3-3220 and 17% slower than the i5-3470.
