Intel Xeon E5-2660 v3 vs Intel Xeon E5-2666 v3

Xeon E5-2660 v3 vs Xeon E5-2666 v3 benchmarks

Our benchmark analysis concludes that the Xeon E5-2666 v3 performs better than the Xeon E5-2660 v3. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2660 v3 in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Xeon E5-2666 v3 has a slightly higher clock speed compared to the Xeon E5-2660 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 E5-2660 v3 has more threads than cores. Each physical core is split into multiple threads.
