Intel Core i5-9400F vs Intel Core i7-3770K

Core i5-9400F vs Core i7-3770K specs and performance

Our benchmark analysis concludes that the Core i5-9400F performs better than the Core i7-3770K. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-3770K in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-9400F has significantly more cores than the Core i7-3770K. Indeed, the Core i5-9400F has 6 cores compared to 4 cores found in the Core i7-3770K. Despite this, the Core i7-3770K has more threads than the Core i5-9400F. These CPUs have different clock speeds. Indeed, the Core i7-3770K 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 i7-3770K CPU because of its slightly 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.
