Having an A10-770K running in an ASRock FM2A88X Extreme6+ for a few days now, so it's time to share banchmarks and observations. Did alot of linux testings and benchmarks. Over at phoronix there was an Kaveri review so i ran my tests against these.


All results beside 7700K are from the Phoronix review. I grouped em in single and multi core benchmarks. The native ones where build with special optimisations on the phoronix review, i did not yet figure out how this was done, so mine where build with default compiler settings and are not directly comparable.

My Specs:
CPU: A10-7700K
BOARD: ASRock FM2A88X Extreme6+
RAM: 2x4GB Crucial Ballistix Tactical DDR3-1866, CL9-9-9-27 (XMP Profile).
SSD. Samsung 840 120GB

Air Cooling: AMD PII Black Edition 125W Heatpipe Cooler
Water Cooling: D-Tec Fusion v2 / Swiftech MCR320 (3x120mm) / Laing D5-Vario 1/2 AG / DangerDen 5,25" Dual Bay Reservoir.

There are two usefull benchmarks for stability testing under linux. The "Open Porous Media" benchmark turned out to be very usefull for quick stability testings and required the highes voltage to pass. Second, the "Primesieve" is the prime95 linux pondon, generates alot of heat is the most energy consuming.

Here is an summary of the lowest voltage required for "Open Porous Media" on various voltages along with the benchmark results and the power consumption at the wall. The turbo mode does not work on that board as soon as mutipliers and voltages are adjusted manually even with C6 and APM enabled. CNQ was enabled.

At around 4400MHz the cpu started to throttle, this happens if the onchip radeon temps exceed 65C. The throttle effect is also visible at the multi core results above at 4.4GHz comparing air and water results. Switching to water cooling reduced the radeon temps from 65C down to 40C at 4.4GHz. At 4.6GHz however they reached 65C again running the primesieve benchmark and the system usually froze.
Will receive an A8-6500 later today so i can run a few benchmarks to get clock vs. clock and turbo efficiency results.
