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 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.
