Core i5-6400 vs Core i7-10510U benchmarks

In our benchmarks, the Core i7-10510U beats the Core i5-6400 in overall performance. Despite this, the Core i5-6400 has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count but the Core i7-10510U has more threads. With our hardware info, we find that the Core i5-6400 has a significantly higher clock speed than the Core i7-10510U. Despite this, the Core i7-10510U has a significantly higher turbo speed. The Core i7-10510U 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. The Core i7-10510U also has slightly more L3 cache.

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.
