Intel Core i5-11400 vs Intel Core i5-8600K

Core i5-11400 vs Core i5-8600K benchmarks

In our benchmarks, the Core i5-11400 beats the Core i5-8600K in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8600K in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores but the Core i5-11400 has more threads. Both the Core i5-11400 and Core i5-8600K have the same clock speed. Despite this, the Core i5-11400 has a slightly higher turbo speed. A Core i5-11400 CPU outputs less heat than a Core i5-8600K CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Core i5-11400 has significantly more L2 cache than the Core i5-8600K. The Core i5-11400 also has slightly 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 i5-11400 has more threads than cores. Each physical core is split into multiple threads.
