Intel Core i5-6600 vs Intel Core i7-5820K

Core i5-6600 vs Core i7-5820K specs and performance

According to the hardwareDB Benchmark tool, the Core i7-5820K is faster than the Core i5-6600. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-6600 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i7-5820K has significantly more cores than the Core i5-6600. Indeed, the Core i7-5820K has 6 cores compared to 4 cores found in the Core i5-6600. It also has more threads than the Core i5-6600. In terms of clock speed, the Core i5-6600 and Core i7-5820K are identical in this regard. Despite this, the Core i5-6600 has a slightly higher turbo speed. A Core i5-6600 CPU outputs less heat than a Core i7-5820K CPU because of its significantly 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. For instance, the Core i5-6600 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
