Core i5-7400 vs Ryzen 7 7840HS comparison

Our benchmark analysis concludes that the Ryzen 7 7840HS performs better than the Core i5-7400. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-7400 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Ryzen 7 7840HS has significantly more cores with 8 cores compared to the Core i5-7400 that has 4 cores. It also has more threads than the Core i5-7400. With our hardware info, we find that the Ryzen 7 7840HS has a slightly higher clock speed than the Core i5-7400. The cache sizes of these CPUs are different. Indeed, the Ryzen 7 7840HS has significantly more L2 cache than the Core i5-7400. The Ryzen 7 7840HS also has significantly 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 i5-7400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
