Intel Core i7-6700K vs Intel Core i5-3570K

Core i7-6700K vs Core i5-3570K specs and performance

According to the hardwareDB Benchmark tool, the Core i7-6700K is faster than the Core i5-3570K. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-3570K in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-6700K has more threads. These CPUs have different clock speeds. Indeed, the Core i7-6700K has a slightly higher clock speed compared to the Core i5-3570K. Also, the Core i7-6700K has a slightly higher turbo speed. The Core i5-3570K outputs less heat than Core i7-6700K thanks to a 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 i7-6700K has more threads than cores. Each physical core is split into multiple threads.
