Core i7-7660U vs Core i5-4690K benchmarks

Our benchmark analysis concludes that the Core i5-4690K 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.

In terms of the number of cores of each of these CPUs, the Core i5-4690K has significantly more cores than the Core i7-7660U. Indeed, the Core i5-4690K has 4 cores compared to 2 cores found in the Core i7-7660U. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Core i5-4690K has a slightly higher clock speed compared to 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 i5-4690K CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Core i7-7660U has more threads than cores. Each physical core is split into multiple threads.
