AMD Performance Results
Compared to the Intel synthetic results, the AMD results are a bit jumbled. The latency and copy speeds improve as the MHz is increased, but oddly the read speed results do not line up perfectly with the frequency like they did on our Intel platform. In fact, the 1600MHz RAM has the best read speeds, followed by the 1866MHz, the 2133MHz and finally ending with the 1333MHz RAM.
Unlike the Intel configuration, we saw enough variance in one of our gaming benchmarks to warrant a little discussion. X3 and Unigine both showed very minimal fluctuations (within our margin of error), but DiRt 2 gave us some interesting results. What is strange is that the 1866MHz RAM (which is the highest frequency natively supported by this CPU) gave us the lowest benchmark scores. The 1333MHz and 2133MHz sticks were pretty much even, with the 1600MHz following just behind.
On our application benchmarks, Euler3d did not show enough of a varience for us to single it out this time around, although WinRar once again shows some performance varience. On our AMD system, compression time using WinRar was improved as the frequency was increased. The extraction results, however, are not as straight forward. In short, they are exactly the opposite of what we saw with the Intel system. On AMD, the 1866MHz RAM had the best extraction time, followed by the 1600MHz RAM. The 2133MHz and 1333MHz results tie for third place with only a minor .01 second difference.
