Intel only launching K-series Alder Lake and Z690 in 2021

German tech writer Igor Wallossek picked up word that Intel will only have K-series and KF-series (without integrated graphics) Alder Lake-S processors in Q4 2021. It will be a launch for enthusiasts only, the only new chipset launching this year will be the Z690. For cheaper Alder Lake processors, as well as the B610, B660, and H670 chipsets, you'll have to wait until 2022.

Unclear why mainstream Alder Lake is delayed

It's unknown why the non-K series Alder Lake processors are delayed. Alder Lake is a new processor architecture with a hybrid design. It will combine up to eight high-performance with eight high-efficiency cores. It requires a motherboard with LGA1700 socket and supports both PCI Express 5.0 and DDR5.

Motherboard makers reject ATX12VO and stick with 24-pin connector

Alder Lake will be manufactured on "Intel 7", the new name of Intel's 10nm Enhanced SuperFin. Igor also reports that motherboard makers will continue to sell Z690 motherboards with 24-pin connectors. Intel tried to push its new ATX12VO but motherboard makers wanted none of this. The advantage of ATX12VO is that it's more efficient and makes cable management easier. The downside is that it requires a new power supply and makes motherboards a bit more expensive.
