The Phenom II X2 550 was able to outperform the Core 2 Duo E7400 in CINEBENCH by a small margin in both the single core and multi-core tests. The Athlon II X2 250 was also faster than the Pentium processors.
Intel processors always seem to score well in the CINEBENCH OpenGL rendering test and we believe this relates somewhat to their excellent gaming performance. The Phenom II processors have improved considerably in this test and as you can see the Phenom II X2 550 is able to match the performance of the Pentium E6300, while it is a bit slower than the Core 2 Duo E7400. The Athlon II X2 250 on the other hand trailed behind the Pentium E5400 by a considerable margin.
