Intel Core i5-6400 vs Intel Core i5-11400F

Core i5-6400 vs Core i5-11400F specs and performance

Our benchmark analysis concludes that the Core i5-11400F performs better than the Core i5-6400. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-6400 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-11400F has significantly more cores than the Core i5-6400. Indeed, the Core i5-11400F has 6 cores compared to 4 cores found in the Core i5-6400. It also has more threads than the Core i5-6400. These CPUs have different clock speeds. Indeed, the Core i5-6400 has a slightly higher clock speed compared to the Core i5-11400F. Despite this, the Core i5-11400F has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). 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.
