Intel's 12th-generation Core processors for desktops are here, and they're fast. Codenamed Alder Lake, these processors consume a lot of power to reach the heights that they do and will require expensive high-performance cooling to match. But in exchange, they deliver healthy single-threaded performance boosts over their closest competition from AMD, and they generally come pretty close in multi-threaded performance tests despite the use of lower-performance "efficiency" cores (or E-cores).
