Xeon E5-2643 vs Xeon E5-2670 v3 specs and performance

In our benchmarks, the Xeon E5-2670 v3 beats the Xeon E5-2643 in overall performance. Despite this, the Xeon E5-2643 has the advantage in our gaming benchmark.

With info from our database, we find that the Xeon E5-2670 v3 has significantly more cores with 12 cores whereas the Xeon E5-2643 has 4 cores. It also has more threads than the Xeon E5-2643. With our hardware info, we find that the Xeon E5-2643 has a significantly higher clock speed than the Xeon E5-2670 v3. Also, the Xeon E5-2643 has a slightly higher turbo speed. The Xeon E5-2670 v3 outputs less heat than Xeon E5-2643 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 E5-2643 has more threads than cores. Each physical core is split into multiple threads.
