Intel Core i7-7820HQ vs Intel Core i5-4570S

Core i7-7820HQ vs Core i5-4570S specs and performance

Our benchmark analysis concludes that the Core i7-7820HQ performs better than the Core i5-4570S. Despite this, the Core i5-4570S has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-7820HQ has more threads. Both the Core i7-7820HQ and Core i5-4570S have the same clock speed. Despite this, the Core i7-7820HQ has a slightly higher turbo speed. A Core i7-7820HQ CPU outputs less heat than a Core i5-4570S 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 i7-7820HQ has more threads than cores. Each physical core is split into multiple threads.
