Intel's Core i9-9900K is here. With eight cores and 16 threads clocked at up to 5 GHz (on as many as two active cores, to boot), plus a 4.7-GHz all-core Turbo Boost 2.0 clock, the i9-9900K has the potential for incredibly formidable performance. We've been testing that performance down to the very last minute, and we have a comprehensive set of results to share with you now, but analysis of those results will have to trickle in as we fully digest the reams of data our work has produced. In honesty, though, a chip with the kinds of performance we've been seeing over the past few days doesn't need us to vouch for much on its behalf.
