Intel Core i5-8259U vs Intel Core i7-8565U

Core i5-8259U vs Core i7-8565U specs and performance

In our benchmarks, the Core i5-8259U 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. Our comparison shows that the Core i5-8259U has a slightly higher clock speed compared to the Core i7-8565U. Despite this, the Core i7-8565U has a slightly higher turbo speed. The Core i7-8565U outputs less heat than Core i5-8259U thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, both these CPUs have the same amount of L2 cache. The Core i7-8565U also has slightly more L3 cache.

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 i5-8259U has more threads than cores. Each physical core is split into multiple threads.
