Intel Core i5-9400F vs AMD Ryzen 9 7900X

Core i5-9400F vs Ryzen 9 7900X comparison

Our benchmark analysis concludes that the Ryzen 9 7900X performs better than the Core i5-9400F. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-9400F in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Ryzen 9 7900X has significantly more cores with 12 cores compared to the Core i5-9400F that has 6 cores. It also has more threads than the Core i5-9400F. With our hardware info, we find that the Ryzen 9 7900X has a significantly higher clock speed than the Core i5-9400F. Also, the Ryzen 9 7900X has a slightly higher turbo speed. A Core i5-9400F CPU outputs less heat than a Ryzen 9 7900X CPU because of its significantly 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 Ryzen 9 7900X has significantly more L2 cache than the Core i5-9400F. The Ryzen 9 7900X also has significantly 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 i5-9400F has the same number of threads as cores. This means the the CPU does not support hyperthreading.
