Intel Core i9-9900 vs Intel Core i9-9900KS

Core i9-9900 vs Core i9-9900KS benchmarks

In our benchmarks, the Core i9-9900KS beats the Core i9-9900 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-9900 in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores 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 Core i9-9900. Furthermore, both these CPUs have identical turbo speeds. A Core i9-9900 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. When comparing cache sizes, these CPUs have an identical amount of L2 cache and L3 cache.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Core i9-9900 has more threads than cores. Each physical core is split into multiple threads.
