AMD Ryzen 3 3300X vs Intel Core i5-9400

Ryzen 3 3300X vs Core i5-9400 specs and performance

Our benchmark analysis concludes that the Ryzen 3 3300X performs better than the Core i5-9400. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-9400 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-9400 has significantly more cores with 6 cores compared to the Ryzen 3 3300X that has 4 cores. Despite this, the Ryzen 3 3300X has more threads than the Core i5-9400. Our comparison shows that the Ryzen 3 3300X has a slightly higher clock speed compared to the Core i5-9400. Also, the Ryzen 3 3300X has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). 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 3 3300X has slightly more L2 cache than the Core i5-9400. The Ryzen 3 3300X also has significantly more L3 cache.

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. Indeed, the Ryzen 3 3300X has more threads than cores. Each physical core is split into multiple threads.
