The Intel's specially binned i9-9900K, featuring 5GHz all core boost and base clock of 4GHz. This CPU is one of the most powerful Intel CPU in term of day-to-day and gaming performance but with TDP of 127W, bulky air cooler or 240mm AIO is recommended to make sure the CPU doesn't overheat, and open loop liquid cooling if you want to OC. [Jun '20 ColdSpy]

MORE DETAILS

Intel’s Alder Lake i5-12400F offers six hyper-threaded performance cores at an MSRP of just $180 USD. This represents excellent value for consumers and, in particular, gamers. It has a boost frequency of 4.4 GHz, 18 MB of L3 cache and a TDP of 65W. The F-version of the CPU does not have integrated graphics, however this will be of little concern to gamers with discrete GPUs. Whilst Intel’s overclockable i5-12600K has four additional efficiency cores and offers around 12% more performance than the 12400F, it also costs around 50% more. The 12400F offers great value, but to achieve optimal performance the requisite B660 motherboard (which supports 3200+ RAM) is, at least for now, difficult to find at reasonable ($150 USD) prices. AMD’s top value hex-core Ryzen 5 5600X offers similar performance for 50% more money. Despite Intel’s price / performance lead, AMD’s prolific marketers (forums, youtube, reddit etc.) have historically outsold Intel whilst carrying a similar handicap. [Jan '22 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.
