Intel Core i7-6820HQ vs Intel Core i5-3570K

Core i7-6820HQ vs Core i5-3570K specs and performance

In our benchmarks, the Core i7-6820HQ beats the Core i5-3570K in overall performance. Despite this, the Core i5-3570K has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-6820HQ has more threads. Our comparison shows that the Core i5-3570K has a slightly higher clock speed compared to the Core i7-6820HQ. Also, the Core i5-3570K has a slightly higher turbo speed. A Core i7-6820HQ CPU outputs less heat than a Core i5-3570K 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. Indeed, the Core i7-6820HQ has more threads than cores. Each physical core is split into multiple threads.
