Core i9-10900 vs Ryzen 5 8645HS specs and performance

In our benchmarks, the Ryzen 5 8645HS beats the Core i9-10900 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-10900 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i9-10900 has significantly more cores with 10 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 Core i9-10900. The cache sizes of these CPUs are different. Indeed, the Ryzen 5 8645HS has significantly more L2 cache than the Core i9-10900. Despite this, the Core i9-10900 has slightly more L3 cache compared to the Ryzen 5 8645HS.

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 Core i9-10900 has more threads than cores. Each physical core is split into multiple threads.
