Core i5-6400 vs Core i5-6600T comparison

In our benchmarks, the Core i5-6600T beats the Core i5-6400 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-6400 in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. Both the Core i5-6400 and Core i5-6600T have the same clock speed. Despite this, the Core i5-6600T has a slightly higher turbo speed. The Core i5-6600T 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 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 i5-6400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
