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

The 16-core, 32-thread Ryzen 9 5950X is an impressive workhorse. It sits at the top of AMD’s latest Zen 3 based, 5000 series of CPUs and sends a clear message that AMD can beat Intel in terms of raw performance and core count. The 5950X has a boost clock speed of up to 4.9 GHz, a massive 72 MB cache and a TDP rating of 105W. Despite the “gaming” focus of AMD’s 5000 series launch marketing, the 5950X does not efficiently leverage all its 16 cores in gaming (as demonstrated by similar effective speed scores compared to the 12-core 5900X, 8-core 5800X and 6-core 5600X.) 16 cores are only suitable for professional use cases that have CPU processing needs which cannot be more efficiently met by a GPU or other dedicated hardware. There is no Intel equivalent with this number of cores, and the 5950X’s uniqueness is reflected in its $799 USD price tag, 45% more expensive than the 5900X. Gamers will get far higher FPS per dollar by allocating a higher proportion of their budget towards a better GPU rather than blowing $799 USD on the 5950X. Professional users that plan to use 32 concurrent threads at 100% load will find value in the 5950X. On the other hand, workstation users that rarely exceed 20 concurrent threads at 100% should consider the 10850K for around half the money. [Nov '20 CPUPro]

 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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
