16 Cores, 24 Threads @3.2GHz, Alder Lake.
Release date: Q4 2021.

Average Bench: 117% (29th of 1459)

Based on 66,991 user benchmarks.  Device: BFEBFBFF00090672 Model: 12th Gen Intel(R) Core(TM) i9-12900K

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]

Amazing for the price. There's no point going the AMD route nowadays as Intel offers more compatibility (DDR4) and much better price to performance. Not sure why anyone would spend more for a worse processor.

This one easily beat 5950X in terms of pure power. Massive gain in multi core performance make it best component for workstation. However, for gaming, 12700K would be better choice. Less TDP (which can spare more power for GPU) and less price tag.

Very Good Performance and even thermal efficiency , on a mid-range water cooler ( nzxt x53) , best value processor coming before the 12700k

ALL FAQs »

 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.
