Intel Core i5-6400 vs Intel Core i5-7400T

Core i5-6400 vs Core i5-7400T benchmarks

Our benchmark analysis concludes that the Core i5-6400 performs better than the Core i5-7400T. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-7400T 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. Our comparison shows that the Core i5-6400 has a slightly higher clock speed compared to the Core i5-7400T. Also, the Core i5-6400 has a slightly higher turbo speed. The Core i5-7400T outputs less heat than Core i5-6400 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The data shows that both these CPUs have same sized L2 caches and L3 cache.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core i5-6400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
