Intel Core i9-9900KS (Coffee Lake) Processor Review

Intel claims its Core i9-9900KS is the CPU you need to build the world's fastest gaming PC. Let's take a close look at those claims.

Intel's 9900K has reigned at the top of the gaming CPU charts for a long time, and today we meet its successor, the 9900KS. The 9900KS is designed to boost all cores to 5GHz, which is very similar to a 9900K with multi-core enhancement turned on.

While the 9900K boosts an all core turbo of 4.7GHz, the 9900KS has the same boost for single and multi-core turbo, which isn't something I have personally seen before. Intel dubs the CPU as the world's fastest gaming processor, so today we will put that to the test.

For the first time in a long time we know the exact turbo table from Intel, directly from Intel, the CPU runs at 5GHz all core Turbo. The CPU has eight cores and 16 threads, and it has a TDP of 127W, which is much higher than the 95W TDP of the 9900K. It also has 16MB of Smart Cache, and is identical to the 9900K except for a 400MHz higher base clock at 4GHz, and a 300MHz higher all core Turbo at 5GHz.


The Core i9-9900KS is priced at $513, but we will see how the market reacts to supply and demand.
