Intel Core i7-7660U vs Intel Core i5-3570

Core i7-7660U vs Core i5-3570 comparison

Our benchmark analysis concludes that the Core i5-3570 performs better than the Core i7-7660U. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-7660U in all gaming tests too.

With info from our database, we find that the Core i5-3570 has significantly more cores with 4 cores whereas the Core i7-7660U has 2 cores. But they both have the same number of threads. With our hardware info, we find that the Core i5-3570 has a slightly higher clock speed than the Core i7-7660U. Despite this, the Core i7-7660U has a slightly higher turbo speed. A Core i7-7660U CPU outputs less heat than a Core i5-3570 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 i7-7660U has more threads than cores. Each physical core is split into multiple threads.
