Intel Core i5-11600K vs Intel Core i7-5820K

Core i5-11600K vs Core i7-5820K comparison

In our benchmarks, the Core i5-11600K beats the Core i7-5820K in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-5820K in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. Our comparison shows that the Core i5-11600K has a slightly higher clock speed compared to the Core i7-5820K. Also, the Core i5-11600K has a slightly higher turbo speed. A Core i5-11600K CPU outputs less heat than a Core i7-5820K CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i5-11600K has more threads than cores. Each physical core is split into multiple threads.
