Intel Xeon E5-2667 v2 vs Intel Xeon E5-2666 v3

Xeon E5-2667 v2 vs Xeon E5-2666 v3 specs and performance

In our benchmarks, the Xeon E5-2666 v3 beats the Xeon E5-2667 v2 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2667 v2 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Xeon E5-2666 v3 has slightly more cores with 10 cores compared to the Xeon E5-2667 v2 that has 8 cores. It also has more threads than the Xeon E5-2667 v2. Our comparison shows that the Xeon E5-2667 v2 has a slightly higher clock speed compared to the Xeon E5-2666 v3.

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 E5-2667 v2 has more threads than cores. Each physical core is split into multiple threads.
