Intel Core i5-6400 vs Intel Core i5-7300U

Core i5-6400 vs Core i5-7300U comparison

According to the hardwareDB Benchmark tool, the Core i5-6400 is faster than the Core i5-7300U. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-7300U in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-6400 has significantly more cores than the Core i5-7300U. Indeed, the Core i5-6400 has 4 cores compared to 2 cores found in the Core i5-7300U. But they both have the same number of threads. With our hardware info, we find that the Core i5-6400 has a slightly higher clock speed than the Core i5-7300U. Despite this, the Core i5-7300U has a slightly higher turbo speed. The Core i5-7300U 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.
