Core i5-8400 vs Core i7-12700H specs and performance

According to the hardwareDB Benchmark tool, the Core i7-12700H is faster than the Core i5-8400. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8400 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i7-12700H has significantly more cores with 14 cores compared to the Core i5-8400 that has 6 cores. It also has more threads than the Core i5-8400. With our hardware info, we find that the Core i5-8400 has a slightly higher clock speed than the Core i7-12700H. Despite this, the Core i7-12700H has a slightly higher turbo speed. The Core i7-12700H outputs less heat than Core i5-8400 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 i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
