Intel is currently rushing to get the launch of the new 12th generation Alder Lake S CPUs off the ground. Generation will be realized before the end of this year, even if this only affects a few products. According to the latest information from my own sources (based on Intel’s Launch Update), Intel is planning to launch the first part of Alder Lake S with only the enthusiast CPUs in the form of the K and KF models along with the Z690 chipset as early as between October 25 and November 19, 2021. The other CPUs of the complete portfolio and the H670, B660 as well as H610 chipsets, on the other hand, are not to be presented until CES 2022.
