Core i7-6700K vs Xeon E5-2650 v3 comparison

According to the hardwareDB Benchmark tool, the Xeon E5-2650 v3 is faster than the Core i7-6700K. Despite this, the Core i7-6700K has the advantage in our gaming benchmark.

With info from our database, we find that the Xeon E5-2650 v3 has significantly more cores with 10 cores whereas the Core i7-6700K 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 significantly higher clock speed compared to the Xeon E5-2650 v3. Also, the Core i7-6700K has a slightly higher turbo speed. A Core i7-6700K CPU outputs less heat than a Xeon E5-2650 v3 CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Core i7-6700K has more threads than cores. Each physical core is split into multiple threads.
