Core i5-8400 vs Core i9-10900 comparison

According to the hardwareDB Benchmark tool, the Core i9-10900 is faster than the Core i5-8400. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8400 in all gaming tests too.

With info from our database, we find that the Core i9-10900 has significantly more cores with 10 cores whereas the Core i5-8400 has 6 cores. It also has more threads than the Core i5-8400. According to our data, the Core i5-8400 and Core i9-10900 have the same clock speed. Despite this, the Core i9-10900 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 info from our database shows that the Core i9-10900 has more L2 cache than the Core i5-8400. The Core i9-10900 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 i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
