Core i9-9900K vs Ryzen 7 7840H benchmarks

Our benchmark analysis concludes that the Ryzen 7 7840H performs better than the Core i9-9900K. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-9900K in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. With our hardware info, we find that the Ryzen 7 7840H has a slightly higher clock speed than the Core i9-9900K. The cache sizes of these CPUs are different. Indeed, the Ryzen 7 7840H has significantly more L2 cache than the Core i9-9900K. However, both these chips have the same amount of L3 cache.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Core i9-9900K has more threads than cores. Each physical core is split into multiple threads.
