AMD Athlon II 250

The ADX250OCK23GQ / ADX250OCGQBOX, the first microprocessor from Athlon II X2 family, was introduced simultaneously with socket AM3 Phenom II X2, X3 and X4 CPUs. The 250 is clocked at 3 GHz, same as Phenom II 545. Even though the ADX250OCK23GQ has twice larger level 2 cache than the 545, it doesn’t have level 3 cache, which results in slightly lower, up to 5%, performance of the 250. Performance of the Athlon II X2 250 is even lower, often by 10% or more, in memory intensive applications, including games. Comparing the 250 with Intel microprocessors is difficult due to big differences in microarchitectures and CPU core efficiency. Depending on application, the 250 can be as slow as Pentium Dual-Core E5200, while in other applications it may be on a par with or faster than Pentium Dual-Core E6300.
