The Intel i9-9900K is an 8 core, 16 thread, unlocked 9th generation Coffee Lake processor. It has a base / boost clocks of 3.6 / 4.7 GHz and a single-core boost of 5.0 GHz (the highest frequency achieved yet from this class of Intel CPU). It features 16 MB of cache, a 95W TDP and Intel UHD 630 graphics. The 9900K is compatible with the new Z390 chipset, and subject to a BIOS update, is also compatible with the older Z370 chipset. Aimed at users who do not wish to compromise, the i9-9900K offers the best gaming and desktop experience available at any price. Heavy workstation users should consider the Ryzen 9 3900X which is similarly priced. Comparing the overclocked 3900X shows that it is just 10% worse for gaming and desktop (sub octa-core) but around 40% better for 64-core computations. Gamers should consider the 9700K which offers identical overclocked gaming performance at a $100 USD discount. [Oct '18 CPUPro]

"Build to perform. Designed to win". Launched 25 November of 2019, this mighty 24 core 48 thread CPU boasts 88 PCIe 4.0 lanes (16 lanes used for high-speed interconnect, 176 PCIe 3.0 lanes effective), 142.25MB of cache, 3.8GHz base and 4.5GHz max boost clock with 280W effective TDP. This CPU competes well with entire of Intel HEDT and Xeon lineup thanks to unprecedented single core performance and insane multi core performance compared to all Intel HEDT CPUs. The new Threadripper 3000 series CPU is (in my opinion) classified as the Extreme High End Desktop (EHEDT) CPU as this CPU has both very high single core and multi core performance, high amount of PCIe lanes and L3 cache and clearly very high price (this CPU costs $1399.99 at launch) which ranks them above HEDT. [Nov '19 ColdSpy]

 Frequently Asked Questions

 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.
