Intel Announces “Alder Lake” 12th Gen Core CPUs
While the world waits until November 4th for performance data, Intel got ahead of the news by announcing its 12th-Gen Core processors:

Headlined the the Core i9-12900K’s mix of eight “performance” and eight “efficiency” cores at clocks up to 5.2 GHz, the new desktop processor series fits the LGA-1700 platforms we outlined last spring. That means it supports both DDR4 and DDR5 memory, PCIe 4 and PCIe 5 graphics cards, and will even be ready for PCIe 5 storage when it becomes available, thanks to the high-end platform’s ability to split the CPU’s sixteen faster lanes across up to three devices.
