Our comparison shows that the Core i5-6600K has a significantly higher clock speed compared to the Core i5-8400T. Also, the Core i5-6600K has a slightly higher turbo speed. The Core i5-8400T outputs less heat than Core i5-6600K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The info from our database shows that the Core i5-8400T has more L2 cache than the Core i5-6600K. The Core i5-8400T 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. For instance, the Core i5-6600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
