Intel Core i5-8365U vs Intel Core i7-8665U

Core i5-8365U vs Core i7-8665U benchmarks

According to the hardwareDB Benchmark tool, the Core i5-8365U is faster than the Core i7-8665U. 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 and the same number of threads. Our comparison shows that the Core i7-8665U has a slightly higher clock speed compared to the Core i5-8365U. 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.

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 i5-8365U has more threads than cores. Each physical core is split into multiple threads.
