We would like to add the results of a few benchmarks here to complete the picture. The thing is that we were curious to see how the performance levels of overclocked Phenom II X2 550 and Athlon II X2 250 would compare to one another and to overclocked dual-core Intel processors. Therefore, the charts below show the performance results for the following CPUs:

  • AMD Phenom II X2 550 at 3.8GHz frequency = 19 х 200MHz. Memory - DDR3 1600 with 7-7-7-20 timings;
  • AMD Athlon II X2 250 at 3.9GHz frequency = 15 x 260MHz. Memory – DDR3 1386 with 6-6-6-18 timings;
  • Intel Pentium E5400 at 4.0GHz frequency = 12 x 333MHz. Memory – DDR3 1333 with 6-6-6-18 timings;
  • Intel Pentium E7400 at 4.0GHz frequency = 10 x 400MHz. Memory – DDR3 1600 with 7-7-7-20 timings.

Note that 4.0GHz frequency for Intel processors was selected as the most typical result easily achieved with air-cooling solutions.

The performance tests showed that dual-core Intel processors remain a more attractive choice for an overclocked system. They boast better overclocking potential, higher end frequencies and as a result, higher performance in overclocked platforms even compared with the new 45nm AMD CPUs. However, things are not that dramatic for AMD, because sometimes the performance difference is fairly small. So, we are sure that enthusiasts should not exclude AMD processors from their possible choices, because overclocking is also a lottery in a way.

At the same time it is quite hard to pick the most optimal solution for overclocking needs from the new AMD offerings even after we have checked out the results. Although we managed to push the frequency of Athlon II X2 250 a little higher than that of Phenom II X2 550, it wasn’t always faster. Sometimes the L3 cache of the new Phenom II X2 mattered more than higher clock frequency.
