The I7-7820X is the second of three new Skylake-X HEDT (high end desktop processors) released by Intel as part of their core X series (the others being the flagship 10-core i9-7900X and the 6-core i7-7800X). The 7820X is an 8-core, 16-thread CPU which will amply satisfy all but the heaviest of multi-threaded use cases. The 7820X requires a relatively expensive X299 (Basin Falls) motherboard, which costs upwards of $250. The 7820X is listed at $599 which is about $200 more than AMD's current flagship 8-core, 16 thread Ryzen 7 1800X. In addition to better IPC, the 7820X is higher clocked with base and max boost clocks of 3.6/4.5 GHz respectively, compared to 3.6G/4.0 GHz for the Ryzen 7 1800X. The additional $200 (50%) buys you around 20% more performance in both single and multi core workloads. Intel have also released several Kabylake-X HEDT CPUs: the 4-thread i5-7640X and the 8-thread i7-7740X and will shortly release of even higher spec Skylake-X processors. It's probably wise to hold off purchasing until the eagerly anticipated 16-core, 32-thread Ryzen Threadripper CPUs are launched later this month. [Jul '17 CPUPro]

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.
