Core i7-6700K vs Xeon E5-2670 v2 benchmarks

Our benchmark analysis concludes that the Xeon E5-2670 v2 performs better than the Core i7-6700K. Despite this, the Core i7-6700K has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Xeon E5-2670 v2 has significantly more cores with 10 cores compared to the Core i7-6700K that has 4 cores. It also has more threads than the Core i7-6700K. Our comparison shows that the Core i7-6700K has a significantly higher clock speed compared to the Xeon E5-2670 v2. Also, the Core i7-6700K has a slightly higher turbo speed. A Core i7-6700K CPU outputs less heat than a Xeon E5-2670 v2 CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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 Core i7-6700K has more threads than cores. Each physical core is split into multiple threads.
