AMD A8-7650K vs AMD Athlon II X4 640

A8-7650K vs Athlon II X4 640 benchmarks

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