The Intel's "super binned" i9-9940X went on as auction only flagship. This 14 core 28 thread CPU has base clock of 4GHz which can turbo to 5GHz (not even all core!). This mighty CPU has very high single core and multi core performance at same time thanks to high clock speed and core count which makes this CPU a powerhouse for nearly every benchmark and game you throw at it. However, because this CPU has TDP of 255W, you're going to need very beefy cooler (especially 420mm radiator with 140mm x 3 Delta fan or open loop liquid cooling) as even the bulkiest air cooler (Noctua NH-D15) can't handle the thermal output of this CPU. This CPU is available only for few select OEM through auction. [Dec '19ColdSpy]
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.
