Core i5-8600K vs Core i7-7800X benchmarks

Our benchmark analysis concludes that the Core i7-7800X performs better than the Core i5-8600K. Despite this, the Core i5-8600K has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count but the Core i7-7800X has more threads. Our comparison shows that the Core i5-8600K has a slightly higher clock speed compared to the Core i7-7800X. Also, the Core i5-8600K has a slightly higher turbo speed. A Core i5-8600K CPU outputs less heat than a Core i7-7800X CPU because of its significantly 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 i5-8600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
