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]

Gaming is more accessible with the i3-12100F: Intel’s entry level Alder Lake desktop processor. Higher end Alder Lake processors feature a combination of performance and efficiency cores, however, the 12100F contains just four hyper-threaded Golden Cove performance cores. It has a max boost frequency of 4.3 GHz, 12 MB of L3 cache and a 58W TDP. The 12100F is keenly priced at around $130 USD and needs to be paired with a new chipset such as the B660. Only users with discrete GPUs should consider “F” models as they do not have integrated graphics. Whilst a budget PC built around the 12100F represents unbeatable value for money, the 6-core i5-12400F, with 50% stronger multi-core, is a better option for gamers with 3060+ tier GPUs. AMD do not have any CPUs competing in this price segment. Entry level gamers, who cannot find reasonably priced discrete GPUs, could consider the similarly performing Ryzen 5 5600G APU which has integrated RX Vega graphics that are around three times faster than Intel's UHD 730. [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.
