AMD Phenom II X4 B50 vs AMD Athlon X4 860K

Phenom II X4 B50 vs Athlon X4 860K comparison

In our benchmarks, the Phenom II X4 B50 beats the Athlon X4 860K in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Athlon X4 860K in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Phenom II X4 B50 has significantly more cores with 4 cores compared to the Athlon X4 860K that has 2 cores. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Athlon X4 860K has a slightly higher clock speed compared to the Phenom II X4 B50. The cache sizes of these CPUs are different. Indeed, the Athlon X4 860K has significantly more L2 cache than the Phenom II X4 B50

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. For instance, the Phenom II X4 B50 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
