Core i5-8400 vs Ryzen 5 PRO 3400G comparison

In our benchmarks, the Core i5-8400 beats the Ryzen 5 PRO 3400G in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 5 PRO 3400G in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-8400 has significantly more cores with 6 cores compared to the Ryzen 5 PRO 3400G that has 4 cores. Despite this, the Ryzen 5 PRO 3400G has more threads than the Core i5-8400. Our comparison shows that the Ryzen 5 PRO 3400G has a slightly higher clock speed compared to the Core i5-8400. The cache sizes of these CPUs are different. Indeed, the Ryzen 5 PRO 3400G has slightly more L2 cache than the Core i5-8400. Despite this, the Core i5-8400 has significantly more L3 cache compared to the Ryzen 5 PRO 3400G.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. For instance, the Core i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
