Intel Core i5-8400T vs Intel Core i3-9100F

Core i5-8400T vs Core i3-9100F comparison

In our benchmarks, the Core i3-9100F beats the Core i5-8400T in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8400T in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-8400T has significantly more cores than the Core i3-9100F. Indeed, the Core i5-8400T has 6 cores compared to 4 cores found in the Core i3-9100F. It also has more threads than the Core i3-9100F. Our comparison shows that the Core i3-9100F has a significantly higher clock speed compared to the Core i5-8400T. Also, the Core i3-9100F has a slightly higher turbo speed. A Core i5-8400T CPU outputs less heat than a Core i3-9100F CPU because of its significantly lower TDP. 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 i5-8400T has significantly more L2 cache than the Core i3-9100F. The Core i5-8400T 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 i5-8400T has the same number of threads as cores. This means the the CPU does not support hyperthreading.
