Phenom II X6 1055T vs Xeon E5-649 comparison

In our benchmarks, the Xeon E5-649 beats the Phenom II X6 1055T in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Phenom II X6 1055T in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. These CPUs have different clock speeds. Indeed, the Phenom II X6 1055T has a slightly higher clock speed compared to the Xeon E5-649. In terms of cache, the Phenom II X6 1055T has significantly more L2 cache when compared to the Xeon E5-649. Despite this, the Xeon E5-649 has significantly more L3 cache compared to the Phenom II X6 1055T.

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 Phenom II X6 1055T has the same number of threads as cores. This means the the CPU does not support hyperthreading.
