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.

Comment  cpu.userbenchmark.com/...

Here's a i9-9900KS compared with last-gen processor giant i9-9990XE. Both of them comes with 4.0GHz base clock which can be boosted to 5.0GHz all cores but the former comes with 8 core 16 thread at $513 (MSRP) but sold at higher price currently while the latter comes with 14 core 28 thread at $3375 (auction estimated retail pricing) but only auctioned to few select OEM.

The fastest for a 9th gen processor! 8 Cores and 16 Threads are great for an Intel CPU!

Is this the real thing?

Too rare to get at a ok price. Just get the 3900X!

Really, Intel? Just re-release a CPU but with higher clocks and less OC potential.

doesn't make sense to buy, high price. just overclock a 9900k.

The fact that this site rates this cpu so high is absolutely hilarious. Numerous tests and benchmarks have shown that even the 3700x trumps this trash and yet it reigns supreme over the likes of the 3970x, I'm sure that if a 3990x were put on this website, it'd be rated lower than an 8700k, even though the 3600 is pretty on par with that. Intel fanboys must love this site for its skewed benchmarks, no wonder the top rated chips are all intel trash
