Intel Core i3-8350K vs Intel Core i5-9400F

Core i3-8350K vs Core i5-9400F benchmarks

According to the hardwareDB Benchmark tool, the Core i5-9400F is faster than the Core i3-8350K. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-8350K 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 i3-8350K. Indeed, the Core i5-9400F has 6 cores compared to 4 cores found in the Core i3-8350K. It also has more threads than the Core i3-8350K. Our comparison shows that the Core i3-8350K has a slightly higher clock speed compared to the Core i5-9400F. The Core i5-9400F outputs less heat than Core i3-8350K thanks to a slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Core i5-9400F has significantly more L2 cache than the Core i3-8350K. The Core i5-9400F 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 i3-8350K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
