Core i5-8400 vs Ryzen 7 5700X3D specs and performance

In our benchmarks, the Ryzen 7 5700X3D beats the Core i5-8400 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8400 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Ryzen 7 5700X3D has slightly more cores than the Core i5-8400. Indeed, the Ryzen 7 5700X3D has 8 cores compared to 6 cores found in the Core i5-8400. It also has more threads than the Core i5-8400. These CPUs have different clock speeds. Indeed, the Ryzen 7 5700X3D has a slightly higher clock speed compared to the Core i5-8400. Also, the Ryzen 7 5700X3D has a slightly higher turbo speed. A Core i5-8400 CPU outputs less heat than a Ryzen 7 5700X3D 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 7 5700X3D has significantly more L2 cache than the Core i5-8400. The Ryzen 7 5700X3D 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 i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
