Intel Core i5-7400 vs Intel Core i5-8300H

Core i5-7400 vs Core i5-8300H benchmarks

According to the hardwareDB Benchmark tool, the Core i5-8300H 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.

Our spec comparison shows that they have an identical amount of cores but the Core i5-8300H has more threads. These CPUs have different clock speeds. Indeed, the Core i5-7400 has a slightly higher clock speed compared to the Core i5-8300H. Despite this, the Core i5-8300H has a slightly higher turbo speed. The Core i5-8300H 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. In terms of cache, both these CPUs have the same amount of L2 cache. The Core i5-8300H 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. For instance, the Core i5-7400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
