Several weeks ago, Intel published a pair of documents on its website that referenced a handful of 9th generation Core processors, spanning the 4-core/4-thread Core i3-9000 on up to the 6-core/6-thread Core i5-9600K. There were no 8-core models listed, though they've been the subject of numerous leaks and rumors, the latest of which offers up some specs.

Computer Base noticed a thread on Coolaler, a Chinese web forum where it's common to find leaked information on unreleased processors, detailing several 9th gen processors. One of them is the rumored Core i9-9900K, an 8-core/16-thread chip that, if real, would be Intel's burliest mainstream processor to date.
