Anandtech published Intel to Launch Core i9-9900KS Next Month: 5 GHz on All Cores
A quote from the article:
At its pre-IFA press event, Intel confirmed that its new enthusiast-class Core i9-9900KS processor will launch in October. The CPU will be very similar to the Core i9-9900K introduced last year, but will feature a higher all-core Turbo frequency when it has sufficient cooling.Intel to Launch Core i9-9900KS Next Month: 5 GHz on All Cores
The Intel Core i9-9900KS will feature eight cores with Hyper-Threading running at 4.0 GHz base frequency and boosting all the way to 5.0 GHz on all cores, up 300 MHz from 4.7 GHz in case of the Core i9-9900K. Essentially, the new CPU is just an eight-core Coffee Lake Refresh silicon binned to hit higher clocks when cooling is good enough.
