Core i5-6600 vs Xeon E5-2666 v3 specs and performance

According to the hardwareDB Benchmark tool, the Xeon E5-2666 v3 is faster than the Core i5-6600. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-6600 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Xeon E5-2666 v3 has significantly more cores with 10 cores compared to the Core i5-6600 that has 4 cores. It also has more threads than the Core i5-6600. Our comparison shows that the Core i5-6600 has a slightly higher clock speed compared to the Xeon E5-2666 v3. The info from our database shows that the Xeon E5-2666 v3 has more L2 cache than the Core i5-6600. The Xeon E5-2666 v3 also has significantly more 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. For instance, the Core i5-6600 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
