Borrowing its memory controller from the Phenom II X4 and X3 families, it's no surprise that the Phenom II X2 550 performs just about on par with our X4 955 in the memory benchmarks. As with the other Phenom II's, however, it's week point it in memory write bandwidth. Still, it manages to pull ahead of the Intel E7400 in every test.
That memory performance helps the X2 550 best the E7400 in the PhotoWorxx benchmark as well. According the Lavalys, this benchmark stresses both the processor and the memory subsystem. The other two tests, though, place more emphasis on the processor itself and allow the E7400 to catch up. Here, the X2 550 and E7400 are essentially matched, each one taking a turn at the lead.
Moving on to floating point benchmarks, the Intel chips appear to have an advantage in the single precision Julia test. However, the double precision (Mandel) and extended precision (Sin Julia) tests seem to level the playing field a bit. In these two tests, the Phenom II X2 550, Intel E7400, and Athlon II X2 250 are all within about 5% of each other. For most users, though, floating point performance isn't nearly as important as the integer performance tested above.
