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

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

According to the hardwareDB Benchmark tool, the Core i5-9300HF is faster than the Core i5-8400H. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8400H in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. Our comparison shows that the Core i5-8400H has a slightly higher clock speed compared to the Core i5-9300HF. Also, the Core i5-8400H 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. The data shows that both these CPUs have same sized L2 caches. The Core i5-8400H also has significantly more L3 cache.

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 i5-8400H has more threads than cores. Each physical core is split into multiple threads.
