Core i9-9820X vs Ryzen 5 8645HS benchmarks

In our benchmarks, the Ryzen 5 8645HS beats the Core i9-9820X in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-9820X in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i9-9820X 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 slightly higher clock speed than the Core i9-9820X. Also, the Ryzen 5 8645HS has a slightly higher turbo speed. The Ryzen 5 8645HS outputs less heat than Core i9-9820X thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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 i9-9820X has more threads than cores. Each physical core is split into multiple threads.
