Core i5-8400T vs Core i7-9750H specs and performance

In our benchmarks, the Core i5-8400T beats the Core i7-9750H in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-9750H in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-9750H has more threads. Our comparison shows that the Core i7-9750H has a significantly higher clock speed compared to the Core i5-8400T. Also, the Core i7-9750H has a slightly higher turbo speed. A Core i5-8400T CPU outputs less heat than a Core i7-9750H CPU because of its slightly 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 i7-9750H also has slightly more L3 cache.

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 i5-8400T has the same number of threads as cores. This means the the CPU does not support hyperthreading.
