Core i5-7400 vs Core i5-9400T specs and performance

Our benchmark analysis concludes that the Core i5-7400 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.

With info from our database, we find that the Core i5-9400T has significantly more cores with 6 cores whereas the Core i5-7400 has 4 cores. It also has more threads than the Core i5-7400. With our hardware info, we find that the Core i5-7400 has a significantly higher clock speed than the Core i5-9400T. Also, the Core i5-7400 has a slightly higher turbo speed. The Core i5-9400T outputs less heat than Core i5-7400 thanks to a significantly lower TDP. 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 i5-9400T has more L2 cache than the Core i5-7400. The Core i5-9400T also has significantly more 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 i5-7400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
