Core i5-6600K vs Xeon E5-2678 v3 specs and performance

According to the hardwareDB Benchmark tool, the Xeon E5-2678 v3 is faster than the Core i5-6600K. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-6600K in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Xeon E5-2678 v3 has significantly more cores than the Core i5-6600K. Indeed, the Xeon E5-2678 v3 has 12 cores compared to 4 cores found in the Core i5-6600K. It also has more threads than the Core i5-6600K. A Core i5-6600K CPU outputs less heat than a Xeon E5-2678 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. For instance, the Core i5-6600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
