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!

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.

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

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
