Intel Xeon E5-2637 v3 vs Intel Xeon E5-2643 v2

Xeon E5-2637 v3 vs Xeon E5-2643 v2 benchmarks

According to the hardwareDB Benchmark tool, the Xeon E5-2643 v2 is faster than the Xeon E5-2637 v3. Despite this, the Xeon E5-2637 v3 has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Xeon E5-2643 v2 has significantly more cores than the Xeon E5-2637 v3. Indeed, the Xeon E5-2643 v2 has 6 cores compared to 4 cores found in the Xeon E5-2637 v3. It also has more threads than the Xeon E5-2637 v3. In terms of clock speed, the Xeon E5-2637 v3 and Xeon E5-2643 v2 are identical in this regard. Despite this, the Xeon E5-2643 v2 has a slightly higher turbo speed. The Xeon E5-2643 v2 outputs less heat than Xeon E5-2637 v3 thanks to a 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 E5-2637 v3 has more threads than cores. Each physical core is split into multiple threads.
