We have finally confirmed the final launch dates of Intel's 12th Gen Alder Lake Desktop CPUs and the Z690 platform from our sources. The company will not only be bringing a new architecture & IPC improvements but the entire chip design is getting an overhaul with the 12th Gen Core family being the first consumer-centric desktop launch of a hybrid x86 processor.

The Intel Alder Lake-S Desktop CPU lineup will include the 12th Gen Core processors. Intel will kick off its lineup with the introductory 'K' and 'KF' chips which will be followed by more mainstream variants in the following weeks (early 2022 around CES).
