12th-Gen Intel Core ‘Alder Lake’ Desktop CPUs Launch
Intel used the Intel Innovation event to mark the launch of its 12th-generation Core CPUs for desktop PCs, the first to use the chipmaker’s new Alder Lake hybrid architecture. The six unlocked models in the lineup make use of two core types, a performance core and an efficiency core to deliver major advancements in both areas. This allows Intel’s new Core i9-12900K, which has 8 performance cores and 8 efficiency cores, to deliver nearly 50 percent multi-threaded performance at a peak power of 241 watts compared to the previous-generation Core i9-11900K at a peak power of 250 watts. Conversely, the Core i9-12900K can provide the same level of multi-threaded performance at roughly one-fourth the power of its predecessor. Intel said the Core i9-12900K can deliver double-digit performance gains over AMD in select games, but it acknowledged that the tests were done before patches were issued to fix performance issues in Windows 11 for AMD CPUs.
