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]

MORE DETAILS

This was the ultimate niche CPU. At the time of its release, it had an optimal combination of multi-core performance without sacrificing as much single- and quad- as the higher-core CPUs, at an excellent price-point. It utilizes quad-channel RAM. If you were a content creator without external funding, had one machine in the budget, then this chip might even now in mid-2019 be what you're looking for. The higher-end Threadrippers will throw more cores at you... for up to five times the price. If you've a home studio, running a DAW on the same PC you use for everything; or you do your own video editing; or you're an independent streamer; then those extra 12 or 18 cores aren't really going to help you that much anyway, for all that extra cash - AND those CPUs have lower performance in more common applications (single- low-thread apps). Not worth it. Intel isn't even on the table, of course. If you're reading this in the future: these benchmarks have multiple categories for a reason. Read and think. Find the best combination for what you intend to do with it - not some arbitrary "the best" overall. There is no such thing, because you won't be using your computer for Overall, now will you? [Aug '19 spacefiddle]

 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.
