Ryzen 7 3800XT vs Core i9-11900 comparison

In our benchmarks, the Ryzen 7 3800XT beats the Core i9-11900 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-11900 in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. With our hardware info, we find that the Ryzen 7 3800XT has a significantly higher clock speed than the Core i9-11900. Despite this, the Core i9-11900 has a slightly higher turbo speed. The Core i9-11900 outputs less heat than Ryzen 7 3800XT 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 3800XT also has significantly more L3 cache.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Ryzen 7 3800XT has more threads than cores. Each physical core is split into multiple threads.
