Intel Xeon E5-2643 vs Intel Xeon E5-2673 v4

Xeon E5-2643 vs Xeon E5-2673 v4 specs and performance

Our benchmark analysis concludes that the Xeon E5-2673 v4 performs better than the Xeon E5-2643. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2643 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Xeon E5-2673 v4 has significantly more cores than the Xeon E5-2643. Indeed, the Xeon E5-2673 v4 has 20 cores compared to 4 cores found in the Xeon E5-2643. It also has more threads than the Xeon E5-2643. A Xeon E5-2643 CPU outputs less heat than a Xeon E5-2673 v4 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 E5-2643 has more threads than cores. Each physical core is split into multiple threads.
