INTEGRATED GRAPHICS TESTING
Our first set of tests focuses on the graphics portion of the APU against other
integrated graphics platforms. Each APU/CPU and motherboard combination was equipped with 4GB of RAM, a 500GB notebook hard drive and a Blu-ray drive.
Energy Efficiency
Under light load, the A10-5700 was only slightly more efficient than the A10-5800K but couldn't quite match the A8-5600K, though all three chips are a step up from Llano and Ivy Bridge.
On more demanding loads, the A10-5700's lower clock speeds helped it achieve some
legitimate power savings. With both the CPU and GPU stressed to their limits,
the 5700 used 30W less than the A8-5600K and 45W less than the A10-5800K. In
real world tests the difference isn't as dramatic; encoding video with TMPGEnc
yielded only a 9W and 21W reduction compared to the 5600K and 5800K respectively.
3D Performance
Note: Discrete GPUs were tested on our GPU testing platform which uses a
Core i3-2100. CPU scaling shouldn't be an issue; we tried out the HD 6570 with
both the i3-2100 and A10-5800K and the difference was less than one frame per
second in almost all of our gaming benchmarks.
In our synthetic tests, on average, the A10-5700's version of the Radeon HD
7660D was about 8% slower A10-5800K, despite only a 5% reduction in GPU clock
speed. While the difference was more than we expected, it was still well ahead
of the A8-5600K.
In Lost Planet 2 and Crysis, two fairly undemanding gaming titles, the A10-5700
ran fairly comfortably at moderate resolutions and medium detail. It trailed
the A10-5800K by only 1~2 frames per second and led the A8-5600K by 3~4 frames
per second.
Sniper Elite V2 and Aliens vs. Predator are more demanding tests, struggling
to run smoothly with low detail levels. Compared to the A10-5800K, the performance
difference was negligible.
