Ryzen 9 5900HS vs Ryzen 9 8945HS comparison

Our benchmark analysis concludes that the Ryzen 9 8945HS performs better than the Ryzen 9 5900HS. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 9 5900HS in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. Our comparison shows that the Ryzen 9 8945HS has a slightly higher clock speed compared to the Ryzen 9 5900HS. Also, the Ryzen 9 8945HS has a slightly higher turbo speed. A Ryzen 9 5900HS CPU outputs less heat than a Ryzen 9 8945HS CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Ryzen 9 8945HS has significantly more L2 cache when compared to the Ryzen 9 5900HS. However, both these chips have the same amount of 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 5900HS has more threads than cores. Each physical core is split into multiple threads.
