Intel Core i5-7400 vs Intel Core i7-10510U

Core i5-7400 vs Core i7-10510U comparison

In our benchmarks, the Core i7-10510U beats the Core i5-7400 in overall performance. Despite this, the Core i5-7400 has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-10510U has more threads. Our comparison shows that the Core i5-7400 has a significantly higher clock speed compared to the Core i7-10510U. Despite this, the Core i7-10510U has a slightly higher turbo speed. The Core i7-10510U outputs less heat than Core i5-7400 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. When comparing cache sizes, these CPUs have an identical amount of L2 cache. The Core i7-10510U also has slightly more L3 cache.

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 i5-7400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
