Intel Core i5-6400T vs Intel Core i7-5600U

Core i5-6400T vs Core i7-5600U benchmarks

In our benchmarks, the Core i5-6400T beats the Core i7-5600U in overall performance. Despite this, the Core i7-5600U has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core i5-6400T has significantly more cores with 4 cores compared to the Core i7-5600U that has 2 cores. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-5600U has a slightly higher clock speed compared to the Core i5-6400T. Also, the Core i7-5600U has a slightly higher turbo speed. The Core i7-5600U outputs less heat than Core i5-6400T thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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 i5-6400T has the same number of threads as cores. This means the the CPU does not support hyperthreading.
