Core i5-8265U vs Core i7-8665U specs and performance

Our benchmark analysis concludes that the Core i7-8665U performs better than the Core i5-8265U. Despite this, the Core i5-8265U has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. Our comparison shows that the Core i7-8665U has a slightly higher clock speed compared to the Core i5-8265U. 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.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Core i5-8265U has more threads than cores. Each physical core is split into multiple threads.
