▲ 8614,939 ▼

8 Cores, 16 Threads @3.6GHz, Coffee Lake.
Release date: Q4 2018.

Average Bench: 97.9% (89th of 1442)

Based on 354,223 user benchmarks.  Devices: BFEBFBFF000906EC, BFEBFBFF000906ED Model: Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz

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]

Funny ppl talking about "fast" "monster gaming" "still great in 2021" (that one made me laugh as if were so technologically advanced compared to what? 2 or 3 years ago lmao) but I dont think they truly understand how CPU function... I GOT A BILLION CORES AND THREADS THAT MEANS IM FAST AS HECK BOYEEEEEE!!! Right? NO! NOT RIGHT! Its all relevant to what you're doing with the CPU! Most games/apps/programs wont even utlize more than 4 cores. My last system was a Z97 Extreme9 mobo, i7 4790k CPU OCd to 4.9 Ghz, 16 GB 2400 Mhz DDR 3 C9 RAM, 1070 GPU, etc... and I could play 99% of new games @60 FPS minimum with many @144 FPS with minor setting tweaks. People with "brand new" systems (because you know the newer the better right?) were averaging the same or slightly better depending on how well the user applied their components. Sure some systems far exceeded my roughly 7 to 8yo system but then again those systems cost over $2000 to $3000 and more. I buy everything USED or open box, etc... I got this i9 for $175 on an ebay auction and honestly its not much better than my Devils Canyon i7 for gameplay. Sure its future proofed but theres no reason for anyone to go out and buy new components every other year. Its just a waste of money.

Double the price of the 2700x for the same 8c/16t configuration but with each core performing ~20% better. Makes no sense for the average mid-high end user (go for a 9700k, 8700k or 2700x). Anyway, if I had to buy the BEST gaming PC possible, I would take the 9900k.

Insanely powerful CPU that is a monster for gaming and streaming, plus unlike any CPU AMD has it can overclock all it's cores to 5.0GHz with a good cooler.

Runs far too hot even with custom water cooling Has to be de lidded or its unusable If Intel fixes the heat issue with smaller fabs then great until then I sent my 4 back

Loved this CPU. It goes great, I've yet to fully overclock it until i get the proper cooling installed. Many people were asking me why I didn't go for an AMD CPU due to getting more value for your buck but I had wanted to buy it since I first started to build a brand new PC. I'm happy with the CPU and haven't had any issues. Used it for many heavy tasks such as gaming, mining and 3D as well as video/photo editing. The price for this, is a bit of a joke (in AU at least I can say) I think I paid around $799 or so..and it comes with 0 fan..but kinda cool packaging..? But if your not building a budget PC, this isn't an issue.

full potential is only unlocked when you disable the 95w tdp and let it consume massive amounts of power while running very hot. Unless you have a high quality board for this chip, the advantages over the ryzen 7 2700x are very slight and not worth the price gap.
