Intel Core i3-7100U vs AMD Athlon II X4 651

Core i3-7100U vs Athlon II X4 651 specs and performance

Our benchmark analysis concludes that the Athlon II X4 651 performs better than the Core i3-7100U. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-7100U in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Athlon II X4 651 has significantly more cores with 4 cores compared to the Core i3-7100U that has 2 cores. 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 i3-7100U.

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 i3-7100U has more threads than cores. Each physical core is split into multiple threads.
