Intel Core i7-6700K vs Intel Xeon E5-1660

Core i7-6700K vs Xeon E5-1660 benchmarks

In our benchmarks, the Xeon E5-1660 beats the Core i7-6700K in overall performance. 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 E5-1660 has significantly more cores with 6 cores compared to the Core i7-6700K that has 4 cores. It also has more threads than the Core i7-6700K. These CPUs have different clock speeds. Indeed, the Core i7-6700K has a slightly higher clock speed compared to the Xeon E5-1660. Also, the Core i7-6700K has a slightly higher turbo speed. A Core i7-6700K CPU outputs less heat than a Xeon E5-1660 CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Core i7-6700K has more threads than cores. Each physical core is split into multiple threads.
