Core i7-8650U vs Core i7-8665U specs and performance

Our benchmark analysis concludes that the Core i7-8665U performs better than the Core i7-8650U. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-8650U in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. In terms of clock speed, the Core i7-8650U and Core i7-8665U are identical in this regard. Despite this, 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 i7-8650U has more threads than cores. Each physical core is split into multiple threads.
