Core i7-8750H vs Core i5-6600K specs and performance

According to the hardwareDB Benchmark tool, the Core i7-8750H is faster than the Core i5-6600K. Despite this, the Core i5-6600K has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Core i7-8750H has significantly more cores than the Core i5-6600K. Indeed, the Core i7-8750H has 6 cores compared to 4 cores found in the Core i5-6600K. It also has more threads than the Core i5-6600K. With our hardware info, we find that the Core i5-6600K has a significantly higher clock speed than the Core i7-8750H. Despite this, the Core i7-8750H has a slightly higher turbo speed. A Core i7-8750H CPU outputs less heat than a Core i5-6600K CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Core i7-8750H has significantly more L2 cache when compared to the Core i5-6600K. The Core i7-8750H also has significantly more L3 cache.

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 i7-8750H has more threads than cores. Each physical core is split into multiple threads.
