Legit Reviews published a review on the Intel Core i9-9900KS CPU
A quote from the article:
Today, Intel unleashed their 9th Gen Core i9-9900KS Special Edition processor to gamers and enthusiasts that are looking to build a new PC or upgrade an old one. Billed as the ultimate gaming processor, the i9-9900KS features up to 5.0 GHz all-core turbo frequency across 8 cores and 16 threads. This processor is a very highly binned Intel Core i9-9900K, so it is only going to be available for a limited time and as such is only backed by a 1-year warranty. Our sources have told us that fewer 9900KS processors were made than last years Intel Core i7-8086K limited edition processor and the same sources let us know that fewer than 50,000 of those were made. Intel sells over 100 million processors a year, so this is a very limited part from Intel.Intel Core i9-9900KS CPU Review
