Intel Core i5-8400 vs Intel Core i5-9300H

Core i5-8400 vs Core i5-9300H specs and performance

Our benchmark analysis concludes that the Core i5-8400 performs better than the Core i5-9300H. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-9300H in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-8400 has significantly more cores with 6 cores compared to the Core i5-9300H that has 4 cores. Despite this, the Core i5-9300H has more threads than the Core i5-8400. Our comparison shows that the Core i5-8400 has a slightly higher clock speed compared to the Core i5-9300H. Despite this, the Core i5-9300H has a slightly higher turbo speed. The Core i5-9300H 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.

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. For instance, the Core i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
