Ryzen 7 8840U vs Core i9-9900KS specs and performance
Our benchmark analysis concludes that the Ryzen 7 8840U 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.
Our spec comparison shows that they have an identical amount of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i9-9900KS has a slightly higher clock speed compared to the Ryzen 7 8840U. Despite this, the Ryzen 7 8840U has a slightly higher turbo speed. A Ryzen 7 8840U CPU outputs less heat than a Core i9-9900KS 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 7 8840U has significantly more L2 cache than the Core i9-9900KS. 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 8840U has more threads than cores. Each physical core is split into multiple threads.
