AMD A8-7650K vs AMD Athlon II X4 640

A8-7650K vs Athlon II X4 640 benchmarks

In our benchmarks, the Athlon II X4 640 beats the A8-7650K in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the A8-7650K in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Athlon II X4 640 has significantly more cores with 4 cores compared to the A8-7650K that has 2 cores. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the A8-7650K has a slightly higher clock speed compared to the Athlon II X4 640. The cache sizes of these CPUs are different. Indeed, the A8-7650K has significantly more L2 cache than the Athlon II X4 640

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. Indeed, the A8-7650K has more threads than cores. Each physical core is split into multiple threads.
