Core i5-7400 vs Core i5-8365U benchmarks

According to the hardwareDB Benchmark tool, the Core i5-8365U is faster than the Core i5-7400. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-7400 in all gaming tests too.

Info from our database shows that they both have the same core count but the Core i5-8365U has more threads. These CPUs have different clock speeds. Indeed, the Core i5-7400 has a significantly higher clock speed compared to the Core i5-8365U. Despite this, the Core i5-8365U has a slightly higher turbo speed. The Core i5-8365U outputs less heat than Core i5-7400 thanks to a significantly lower TDP. 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. For instance, the Core i5-7400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
