Ryzen 7 5800X vs Ryzen 9 3950X comparison

In our benchmarks, the Ryzen 9 3950X beats the Ryzen 7 5800X in overall performance. Despite this, the Ryzen 7 5800X has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Ryzen 9 3950X has significantly more cores with 16 cores compared to the Ryzen 7 5800X that has 8 cores. It also has more threads than the Ryzen 7 5800X. Our comparison shows that the Ryzen 7 5800X has a slightly higher clock speed compared to the Ryzen 9 3950X. Furthermore, both these CPUs have identical turbo speeds. 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 9 3950X has significantly more L2 cache than the Ryzen 7 5800X. The Ryzen 9 3950X 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 7 5800X has more threads than cores. Each physical core is split into multiple threads.
