Ryzen 7 5800X vs Core i9-9900KS comparison

Our benchmark analysis concludes that the Ryzen 7 5800X performs better than the Core i9-9900KS. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-9900KS 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 Core i9-9900KS has a slightly higher clock speed than the Ryzen 7 5800X. Also, the Core i9-9900KS has a slightly higher turbo speed. A Ryzen 7 5800X CPU outputs less heat than a Core i9-9900KS CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The info from our database shows that the Ryzen 7 5800X has more L2 cache than the Core i9-9900KS. The Ryzen 7 5800X also has significantly more 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 Ryzen 7 5800X has more threads than cores. Each physical core is split into multiple threads.
