Intel Xeon E5-2690 v2 vs Intel Xeon E5-2666 v3

Xeon E5-2690 v2 vs Xeon E5-2666 v3 comparison

According to the hardwareDB Benchmark tool, the Xeon E5-2666 v3 is faster than the Xeon E5-2690 v2. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2690 v2 in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. These CPUs have different clock speeds. Indeed, the Xeon E5-2690 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 E5-2690 v2 has more threads than cores. Each physical core is split into multiple threads.
