Core i7-8665U vs Core i5-4690S specs and performance

In our benchmarks, the Core i5-4690S beats the Core i7-8665U in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-8665U in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores but the Core i7-8665U has more threads. Our comparison shows that the Core i5-4690S has a significantly 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 i5-4690S CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i7-8665U has more threads than cores. Each physical core is split into multiple threads.
