Intel Xeon E5-520 vs AMD Phenom II X6 1065T

Xeon E5-520 vs Phenom II X6 1065T comparison

In our benchmarks, the Phenom II X6 1065T beats the Xeon E5-520 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-520 in all gaming tests too.

With info from our database, we find that the Phenom II X6 1065T has significantly more cores with 6 cores whereas the Xeon E5-520 has 4 cores. It also has more threads than the Xeon E5-520. Our comparison shows that the Phenom II X6 1065T has a slightly higher clock speed compared to the Xeon E5-520. The cache sizes of these CPUs are different. Indeed, the Phenom II X6 1065T has significantly more L2 cache than the Xeon E5-520. Despite this, the Xeon E5-520 has slightly more L3 cache compared to the Phenom II X6 1065T.

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 Xeon E5-520 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
