Intel’s 16-core flagship Alder Lake i9-12900K processor delivers a staggering performance improvement over it's predecessor (+70% 64-core). It features a new hybrid architecture which combines eight hyper-threaded performance cores with eight efficiency cores for a total of 24 threads. Alder Lake CPUs will require a new Z690 chipset which supports DDR5 memory and PCIe 5.0. At an MRSP of $590 USD, the i9-12900K is aimed at power users who demand the best of the best. That said, Intel’s 10-core 12600K matches the 12900K’s performance for the majority of consumer use cases at a 50% price discount. [Nov '21 CPUPro]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate countless reddit accounts. UserBenchmark’s data exposes their marketing spiel so they systematically attack our reputation.
Why don’t large PC brands support UserBenchmark?
PC brands profit greatly from flagship hardware like the 4090, 14900KS, and 7950X3D. We help users get similar real-world performance for less money.
Why don’t any youtubers promote UserBenchmark?
We don't sponsor youtubers, so they have no incentive to praise us. Moreover, brands pay more to market weaker products which puts their youtubers at odds with UserBenchmark.
Why does UserBenchmark have so many negative trustpilot reviews?
Trustpilot hosts user-generated online reviews. It's obvious that the 200+ UserBenchmark reviews, are mostly written by virgin marketing accounts. Real users aren't interested in promoting billon-dollar brands...
Why is UserBenchmark so popular with users?
Instead of pursuing lucrative sponsorships with billion-dollar PC brands, we have dedicated 13 years to publishing accurate real-world data. As a result, our users save millions every year and they return repeatedly.
