Former Intel CEO Pat Gelsinger was very excited showcased Lunar Lake CPU based on Intel 18A up and running on laptop at Intel Innovation 2023 conference back on 19 September 2023. He confirmed both 20A and 18A was on track for risk productions in Q1 2024 and volume productions in second half of 2024 for both Arrow Lake on 20A and Lunar Lake on 18A.
Pat Gelsinger said on his twitter smaller dies will have high yield. Lunar Lake die size on TSMC N3B was 140mm2, on Intel 18A it could be around 100mm2 supposed to be at high yield so something gone wrong with 18A caused switched it to TSMC N3B.
Computercity author probably wrote article weeks ago before Lunar Lake announcement in September 2024, unaware Lunar Lake compute tile was switched to TSMC N3B instead.
Intel officially launched its latest mobile processor, Lunar Lake, on September 3rd, 2024. Some laptop models will launch later in September, but many

Edit: Intel confirmed back in January 2023 Lunar Lake CPUs will be on Intel 18A process targeted at 15W TDP, it seemed Intel 18A with smaller die size and lower TDP was superior to TSMC N3B large die size and 17W-30W TDP.
Intel Lunar Lake is a new architecture designed for low-power mobile devices. The company is to disclose more details later this month. Officially Lunar Lake is to feature Foveros packaging technology, and it should be based on Intel 18A node. Intel is not confirming the release date, apart...
