Intel Xeon E5-2620 v3 vs Intel Xeon E5-2665

Xeon E5-2620 v3 vs Xeon E5-2665 benchmarks

In our benchmarks, the Xeon E5-2620 v3 beats the Xeon E5-2665 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2665 in all gaming tests too.

With info from our database, we find that the Xeon E5-2665 has slightly more cores with 8 cores whereas the Xeon E5-2620 v3 has 6 cores. It also has more threads than the Xeon E5-2620 v3. In terms of clock speed, the Xeon E5-2620 v3 and Xeon E5-2665 are identical in this regard. Despite this, the Xeon E5-2620 v3 has a slightly higher turbo speed. A Xeon E5-2620 v3 CPU outputs less heat than a Xeon E5-2665 CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Xeon E5-2620 v3 has more threads than cores. Each physical core is split into multiple threads.
