Intel's website mentions this 12th Gen CPU was *formerly* known as Alder Lake, 
was released in Q1 2022, but does not make it clear what it is now named as:

https://www.intel.co.uk/content/www/uk/en/products/sku/132228/intel-core-i712700h-processor-24m-cache-up-to-4-70-ghz/specifications.html

So, I'd be inclined to take their word for it.  This Wikipedia lists the 
processor as a mobile Alder Lake:

https://en.wikipedia.org/wiki/Alder_Lake#Alder_Lake-H

The Tiger Lake processors are 11th Gen and their model numbering start with 
11***.

This page also confirms your family and model number as per cpuinfo use the 
Golden Cove (P-cores) microarchitecture:

https://en.wikichip.org/wiki/intel/microarchitectures/alder_lake#CPUID

sys-apps/dmidecode will provide additional information to determine the 
specifics of what the MoBo firmware reports.
