Intel Core i5-4440S vs AMD Phenom II X4 955

Core i5-4440S vs Phenom II X4 955 specs and performance

Our benchmark analysis concludes that the Core i5-4440S performs better than the Phenom II X4 955. Furthermore, our gaming benchmark shows that it also outperforms the Phenom II X4 955 in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Phenom II X4 955 has a slightly higher clock speed compared to the Core i5-4440S.

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 Core i5-4440S has the same number of threads as cores. This means the the CPU does not support hyperthreading.
