AMD Athlon II 7850 Black Edition AM2+ CPU Review

» Discuss this article (9)


To test how the new Athlon X2 7850 processor performs, I will put it through a series of benchmarks that test the scientific and video processing capabilities. To give you a comparison on how it compares to mainstream processors being used currently, I will place the results up against some other processors - including dual core, triple core, and quad core CPUs. This will give you an idea where the X2 7850 sits among other processors in its class and beyond. All hardware used was set to its native operating speeds, timings, and voltages to keep any variables from interfering with the scores. Because of time constraints and hardware availability, the video testing phase will have some of the newer chips included, however not all of them will be shown.

Overclocked settings:

  • Processor: AMD Athlon X2 7850 @ 3.201GHz (207x15.5) 1.45v
  • System Memory: Mushkin Redline XP2 @ 826MHz (5-5-5-12)

Overclocking the AMD Athlon X2 7850, even though it is a Black Edition processor, was a tedious task. AMD supplied us with nominal voltages of 1.2-1.25v, so to overclock I had to push the processor to 1.45v to reach any kind of stability. At that voltage, I was only able to push the multiplier to x15.5, which is only x1.5 more than the stock multiplier. Anything over x15.5 and the system would not boot at all. The same happened with the BUS speed - it maxed out at 207Mhz, with no more room to give. I even tried to keep the multi at x14 and push the BUS speed only, and I hit a wall at 224Mhz for a total of 3.136GHz, so the other option was a bit faster. For the overclocking tests, the speed will be 3.201GHz at 1.45v.
