Ryzen 7 7730U vs Ryzen 5 8645HS benchmarks

Our benchmark analysis concludes that the Ryzen 5 8645HS performs better than the Ryzen 7 7730U. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 7 7730U in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Ryzen 7 7730U has slightly more cores with 8 cores compared to the Ryzen 5 8645HS that has 6 cores. It also has more threads than the Ryzen 5 8645HS. With our hardware info, we find that the Ryzen 5 8645HS has a significantly higher clock speed than the Ryzen 7 7730U. Also, the Ryzen 5 8645HS has a slightly higher turbo speed. A Ryzen 7 7730U CPU outputs less heat than a Ryzen 5 8645HS CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Ryzen 5 8645HS has significantly more L2 cache than the Ryzen 7 7730U. 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 7 7730U has more threads than cores. Each physical core is split into multiple threads.
