Ryzen 9 5900HX vs Ryzen 9 6900HX comparison

In our benchmarks, the Ryzen 9 6900HX beats the Ryzen 9 5900HX in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 9 5900HX in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Ryzen 9 6900HX has a slightly higher clock speed compared to the Ryzen 9 5900HX. Also, the Ryzen 9 6900HX 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. When comparing cache sizes, these CPUs have an identical amount of L2 cache and 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 9 5900HX has more threads than cores. Each physical core is split into multiple threads.
