Intel Core i5-8400 vs Intel Core i7-5930K

Core i5-8400 vs Core i7-5930K benchmarks

In our benchmarks, the Core i7-5930K beats the Core i5-8400 in overall performance. Despite this, the Core i5-8400 has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-5930K has more threads. With our hardware info, we find that the Core i7-5930K has a slightly higher clock speed than the Core i5-8400. Despite this, the Core i5-8400 has a slightly higher turbo speed. A Core i5-8400 CPU outputs less heat than a Core i7-5930K CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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 i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
