Intel Xeon E5-2640 v3 vs Intel Xeon E5-520

Xeon E5-2640 v3 vs Xeon E5-520 specs and performance

Our benchmark analysis concludes that the Xeon E5-2640 v3 performs better than the Xeon E5-520. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-520 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Xeon E5-2640 v3 has significantly more cores with 8 cores compared to the Xeon E5-520 that has 4 cores. It also has more threads than the Xeon E5-520. These CPUs have different clock speeds. Indeed, the Xeon E5-2640 v3 has a slightly higher clock speed compared to the Xeon E5-520. Also, the Xeon E5-2640 v3 has a slightly higher turbo speed. The Xeon E5-520 outputs less heat than Xeon E5-2640 v3 thanks to a slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Xeon E5-2640 v3 has more threads than cores. Each physical core is split into multiple threads.
