Core i7-4558U vs Athlon II X4 651 comparison

Our benchmark analysis concludes that the Athlon II X4 651 performs better than the Core i7-4558U. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-4558U in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Athlon II X4 651 has significantly more cores than the Core i7-4558U. Indeed, the Athlon II X4 651 has 4 cores compared to 2 cores found in the Core i7-4558U. But they both have the same number of threads. With our hardware info, we find that the Athlon II X4 651 has a slightly higher clock speed than the Core i7-4558U.

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 Core i7-4558U has more threads than cores. Each physical core is split into multiple threads.
