Intel Core i5-8400 vs Intel Core i9-10900F

Core i5-8400 vs Core i9-10900F benchmarks

Our benchmark analysis concludes that the Core i9-10900F 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 i9-10900F has significantly more cores than the Core i5-8400. Indeed, the Core i9-10900F has 10 cores compared to 6 cores found in the Core i5-8400. It also has more threads than the Core i5-8400. According to our data, the Core i5-8400 and Core i9-10900F have the same clock speed. Despite this, the Core i9-10900F 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 cache sizes of these CPUs are different. Indeed, the Core i9-10900F has significantly more L2 cache than the Core i5-8400. The Core i9-10900F 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 i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
