Intel Xeon E5-2666 v3 vs Intel Xeon E5-2687W v3

Xeon E5-2666 v3 vs Xeon E5-2687W v3 benchmarks

According to the hardwareDB Benchmark tool, the Xeon E5-2666 v3 is faster than the Xeon E5-2687W v3. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2687W 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 E5-2687W v3 has a slightly higher clock speed compared to the Xeon E5-2666 v3. The data shows that both these CPUs have same sized L2 caches and L3 cache.

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 E5-2666 v3 has more threads than cores. Each physical core is split into multiple threads.
