Ryzen 7 3800X vs Ryzen 9 5900HS specs and performance

In our benchmarks, the Ryzen 7 3800X beats the Ryzen 9 5900HS in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 9 5900HS in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. Our comparison shows that the Ryzen 7 3800X has a slightly higher clock speed compared to the Ryzen 9 5900HS. The Ryzen 9 5900HS outputs less heat than Ryzen 7 3800X thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, both these CPUs have the same amount of L2 cache. The Ryzen 7 3800X 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 3800X has more threads than cores. Each physical core is split into multiple threads.
