Intel Core i7-8565U vs Intel Core i7-8665U

Core i7-8565U vs Core i7-8665U specs and performance

In our benchmarks, the Core i7-8665U beats the Core i7-8565U in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-8565U in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-8665U has a slightly higher clock speed compared to the Core i7-8565U. Also, the Core i7-8665U has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). 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 i7-8565U has more threads than cores. Each physical core is split into multiple threads.
