Intel Core i3-9100F vs Intel Core i5-9400F

Core i3-9100F vs Core i5-9400F comparison

In our benchmarks, the Core i5-9400F beats the Core i3-9100F in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-9100F in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-9400F has significantly more cores with 6 cores compared to the Core i3-9100F that has 4 cores. It also has more threads than the Core i3-9100F. Our comparison shows that the Core i3-9100F has a slightly higher clock speed compared to the Core i5-9400F. Also, the Core i3-9100F 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 i5-9400F has more L2 cache than the Core i3-9100F. The Core i5-9400F 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 i3-9100F has the same number of threads as cores. This means the the CPU does not support hyperthreading.
