Intel Core i9-9900KS Review: The Fastest Gaming CPU Bar None
Performance Summary: The Intel Core i9-9900KS performed very well throughout our array of tests, and depending on your particular use-case, an argument could be made that it’s the fastest mainstream desktop CPU currently available. There is – of course – some nuance to that statement.
The Core i9-9900KS is the fastest processor we’ve tested for single and lightly-threaded workloads. It put up top marks in all of the single-threaded focused benchmarks, led the pack in lightly threaded tests like LAME MT, and also offered the highest performance in our gaming and graphics tests. According to PCMark 10, the Core i9-9900KS also took the lead in the overall score, bolstered by its strong productivity results. In more heavily-threaded workloads that can leverage all of the additional processing resources available in a 12-core CPU like the Ryzen 9-3900X, however, the 8-core Intel Core i9-9900KS can’t keep up. It did catch AMD’s 12-core Threadripper 2920X, which is based on the previous-gen Zen+ architecture, on a couple of occasions, however.

We’d be remiss if we didn’t mention that Intel needs a next-gen architecture and the move to a more advanced manufacturing process to better battle AMD’s increased core counts and the power advantages of the Ryzen 3000 series, but the company is just not there yet. In the meantime, the Core i9-9900KS and impending Cascade Lake-X parts will be Intel’s weapons of choice and they are still powerful weapons indeed.
