This AnandTech slide is an utter misrepresentation of what Intel actually announced in mid-2021. TLDR: Intel's roadmap has remained the same sind mid-2020, there have been 0 delays and 1 pull-in.
*The HVM window for all nodes has always been 6 months. For Intel 4 it was H2'22... And Intel just announced that it has started manufacturing on Intel 4, so it is on schedule.
*Intel is known for its annual cadence. Meteor Lake in H2'23 is consistent with Raptor Lake in H2'22 (even if Bob Swan did initially say early 2023. Pat Gelsinger has never said this).
*20A has always been H1'24 (in time for Arrow Lake launch in H2'24), so the AnandTech timeline is wrong.
*18A was initially early 2025 (not mid-2025 like the AnandTech slide), but Intel has since pulled this in to H2'24.
