Whats not to like?! 5.2ghz all core out the box! King of Core Speed! (the moaners should have purchased at release when its was £500 and better value than the current £1700 - now rare as rocking horse poo). This CPU is MONSTER!

most powerful gaming cpu in 2019


19 months ago.

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?

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.
