Intel Core i5-8400 vs Intel Core 5 120U

Core i5-8400 vs Core 5 120U benchmarks

Our benchmark analysis concludes that the Core 5 120U performs better than the Core i5-8400. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8400 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core 5 120U has significantly more cores than the Core i5-8400. Indeed, the Core 5 120U has 10 cores compared to 6 cores found in the Core i5-8400. It also has more threads than the Core i5-8400. With our hardware info, we find that the Core i5-8400 has a significantly higher clock speed than the Core 5 120U. In terms of cache, the Core 5 120U has significantly more L2 cache when compared to the Core i5-8400. The Core 5 120U also has slightly 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 i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
