Intel Xeon E5-2643 v2 vs Intel Xeon E5-2667 v4

Xeon E5-2643 v2 vs Xeon E5-2667 v4 specs and performance

Our benchmark analysis concludes that the Xeon E5-2667 v4 performs better than the Xeon E5-2643 v2. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2643 v2 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Xeon E5-2667 v4 has slightly more cores with 8 cores compared to the Xeon E5-2643 v2 that has 6 cores. It also has more threads than the Xeon E5-2643 v2. These CPUs have different clock speeds. Indeed, the Xeon E5-2643 v2 has a slightly higher clock speed compared to the Xeon E5-2667 v4. Also, the Xeon E5-2643 v2 has a slightly higher turbo speed. A Xeon E5-2643 v2 CPU outputs less heat than a Xeon E5-2667 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 v2 has more threads than cores. Each physical core is split into multiple threads.
