Intel Xeon E5-2640 vs Intel Xeon E5-620

Xeon E5-2640 vs Xeon E5-620 benchmarks

Our benchmark analysis concludes that the Xeon E5-2640 performs better than the Xeon E5-620. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-620 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Xeon E5-2640 has significantly more cores than the Xeon E5-620. Indeed, the Xeon E5-2640 has 6 cores compared to 4 cores found in the Xeon E5-620. It also has more threads than the Xeon E5-620. Our comparison shows that the Xeon E5-620 has a slightly higher clock speed compared to the Xeon E5-2640. Despite this, the Xeon E5-2640 has a slightly higher turbo speed. The Xeon E5-620 outputs less heat than Xeon E5-2640 thanks to a slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Xeon E5-2640 has significantly more L2 cache when compared to the Xeon E5-620. The Xeon E5-2640 also has significantly more L3 cache.

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 has more threads than cores. Each physical core is split into multiple threads.
