The Intel's specially binned i9-9900K, featuring 5GHz all core boost and base clock of 4GHz. This CPU is one of the most powerful Intel CPU in term of day-to-day and gaming performance but with TDP of 127W, bulky air cooler or 240mm AIO is recommended to make sure the CPU doesn't overheat, and open loop liquid cooling if you want to OC. [Jun '20 ColdSpy]

MORE DETAILS

Even though it may be the most powerful CPU in the market, it's not worth it for gaming―unless you want to stream and video render. This CPU will dominate any workstation load, but its single-core performance is much slower than an i7-8700k, i5-8600k, and i3-8350k. So, in a nutshell, this CPU is only meant for hardcore streaming and workstation computers. [Jun '18 specify_cs]
