Intel Core i5-9400F vs Intel Core i7-5930K

Core i5-9400F vs Core i7-5930K benchmarks

In our benchmarks, the Core i7-5930K beats the Core i5-9400F in overall performance. Despite this, the Core i5-9400F 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. These CPUs have different clock speeds. Indeed, the Core i7-5930K has a slightly higher clock speed compared to the Core i5-9400F. Despite this, the Core i5-9400F has a slightly higher turbo speed. A Core i5-9400F 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.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. For instance, the Core i5-9400F has the same number of threads as cores. This means the the CPU does not support hyperthreading.
