AMD Kaveri A10-7850K (With Radeon R7 Spectre GPU) Quick Test



AMD Kaveri APU A10-7850K


This short test/review can be seen as an update of the A10-6800K test. The testbed is the same (ASRock FM2 A88M Extreme4+, 8 GB of DDR3-2400 Patriot Viper), I only swapped the A10-6800K for the brand new A10-7850K APU launched two weeks ago.

Some pictures of the A10-7850K box:

OK let’s look at the interesting things, the software side. To enjoy the A10-7850K, I updated the motherboard BIOS (very easy thanks to a live update option in the BIOS settings) and I installed the latest Catalyst 13.30-140108a (beta version) with support of new Kaveri APUs. The BIOS update has improved the stability of the ASRock FM2A88M based tested with the Patriot Viper 8GB DDR3-2400 memory kit. The Corsair Airflow module is no longer required. Great!

Here are some screenshots of an updated version of GPU Caps Viewer:

The OpenCL panel shows the GPU codename of the A10-7850K GPU: Spectre.

Now some performance tests. The first test is the OpenGL 4.3 compute shaders demo available in the code sample pack of GLSL Hacker. To compare apples with apples, I set the DDR3 speed clock to 1600MHz because this compute shader demo has been tested with the A10-6800K + DDR3 1600:

Under the same conditions (DDR3 1600), the A10-6800K ran the demo at around 164 FPS while our new A10-7850K shows a nice 550 FPS!


Now the other tests with DDR3 2400:




GpuTest – FurMark test (OpenGL 3.2)

  1024×640 windowed 1920×1080 fullscreen
A10-6800K Radeon HD 8670D + DDR3 2400 1123 points, 20FPS 695 points, 11FPS
A10-7850K Radeon R7 + DDR3 2400 1103 points, 18FPS (-2%) 646 points, 10FPS (-7%)






GpuTest – TessMark X16 test (OpenGL 4.0)

  1024×640 windowed 1920×1080 fullscreen
Radeon HD 8670D + DDR3 2400 14398 points, 240FPS 9736 points, 162PS
A10-7850K Radeon R7 + DDR3 2400 18905 points, 315FPS (+31%) 10821 points, 180FPS (+11%)






GpuTest – Volplosion (OpenGL 3.2)

  1024×640 windowed 1920×1080 fullscreen
Radeon HD 8670D + DDR3 2400 1306 points, 21FPS 424 points, 7FPS
A10-7850K Radeon R7 + DDR3 2400 1426 points, 23FPS (+9%) 461 points, 7FPS (+8%)






3DMark (2013)

  Ice Storm Cloud Gate Fire Strike
Radeon HD 8670D + DDR3 2400 73517 6574 1173
A10-7850K Radeon R7 + DDR3 2400 70423 (-5%) 6999 (+6%) 1522 (+30%)



In most of the tests, the A10-7850K is faster than the A10-6800K. But in some tests (3DMark Ice Storm or the FurMark module of GpuTest), the A10-7850K is slower. Maybe we can attribute this weakness to the Catalyst driver that is in beta version and is the first driver to support the A10-7850K. Wait and see if next versions of Catalyst drivers will improve these scores.

  1. RC

    What were the specifics of your memory? Timings and was it 2400 or 2133 oc’d?

  2. Promilus

    Any chance to make some dx/ogl/mantle demo and have perf. differences displayed?

  3. JeGX Post Author

    @RC: memory timing: 10-12-12-30, 2400MHz

    @kim: as soon as I find a little time…

    @Promilius: if AMD plans to release a public SDK, sure I will play with it.
