Ryzen 9 3900X vs Ryzen 9 3900XT specs and performance

In our benchmarks, the Ryzen 9 3900XT beats the Ryzen 9 3900X in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 9 3900X in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. These CPUs have different clock speeds. Indeed, the Ryzen 9 3900X has a slightly higher clock speed compared to the Ryzen 9 3900XT. Despite this, the Ryzen 9 3900XT 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 data shows that both these CPUs have same sized L2 caches and 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 9 3900X has more threads than cores. Each physical core is split into multiple threads.
