Xeon E5-2620 v3 vs Xeon E5-2643 v2 specs and performance

In our benchmarks, the Xeon E5-2643 v2 beats the Xeon E5-2620 v3 in overall performance. Despite this, the Xeon E5-2620 v3 has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count and the same number of threads. Our comparison shows that the Xeon E5-2643 v2 has a significantly higher clock speed compared to the Xeon E5-2620 v3. Also, the Xeon E5-2643 v2 has a slightly higher turbo speed. A Xeon E5-2620 v3 CPU outputs less heat than a Xeon E5-2643 v2 CPU because of its significantly 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.
