Videocardz today reported on one of the fundamental questions regarding Intel's upcoming Alder Lake: its release date. According to the publication, and citing industry sources, Intel is planning to launch Alder Lake-S come November 4th, 2021. The 12th Gen family of Intel core processors can not come soon enough for the blue giant, who sees itself embattled against the David-like rise of AMD via its Zen architecture. Especially if they do materialize with a 27% single-thread performance improvement over Zen 3.

The release date was first originally referenced by an MSI press release regarding the availability of an upgrade kit for its MAG Coreliquid K and MPG Coreliquid X - both AIO solutions will require new mounting mechanisms for Alder Lake's LGA 1700 socket, and their release is pegged to November 4th as well - this prompted the industry insider sources to confirm the release date. According to WCCFTech, the actual release timeline for the announcement and pre-orders is set for October 27th, whilst the actual product launch and review embargo lifts on November 4th, which is the market availability date
 
This info is rumor, but the date would make sense if Intel wants to take financial advantage of the holiday shopping season.

This release and the CPUs are going to be scrutinized closely to see if Gelsinger, as Intel's CEO, has taken the company out of its lackadaisical CPUs over the last few years.

Most of the blame for that is on the Intel fabs and the slow transition to 10nm. The most important thing that has happened is the Intel price decreases due to AMD Ryzen CPUs.

I don't want that stupid big-little.  I want 12 big cores, proper 10nm monolithic. 

What I'm waiting to see is the next HEDT.  It may happen sometime next year.
