Core i7-8665U vs Core i7-2820QM comparison

Our benchmark analysis concludes that the Core i7-8665U performs better than the Core i7-2820QM. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-2820QM in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-2820QM has a slightly higher clock speed compared to the Core i7-8665U. Despite this, the Core i7-8665U has a slightly higher turbo speed. A Core i7-8665U CPU outputs less heat than a Core i7-2820QM 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 i7-8665U has more threads than cores. Each physical core is split into multiple threads.
