Intel Core i5-9400T vs Intel Core i5-9400F

Core i5-9400T vs Core i5-9400F specs and performance

Our benchmark analysis concludes that the Core i5-9400F performs better than the Core i5-9400T. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-9400T in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i5-9400F has a significantly higher clock speed compared to the Core i5-9400T. Also, the Core i5-9400F has a slightly higher turbo speed. A Core i5-9400T CPU outputs less heat than a Core i5-9400F CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, both these CPUs have the same amount of L2 cache and L3 cache.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. For instance, the Core i5-9400T has the same number of threads as cores. This means the the CPU does not support hyperthreading.
