Athlon II X4 640 vs Phenom II X4 955 specs and performance
Our benchmark analysis concludes that the Phenom II X4 955 performs better than the Athlon II X4 640. Furthermore, our gaming benchmark shows that it also outperforms the Athlon II X4 640 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 Athlon II X4 640. In terms of cache, the Athlon II X4 640 has significantly more L2 cache when compared to the Phenom II X4 955
The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. For instance, the Athlon II X4 640 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
