23 | Intel's website mentions this 12th Gen CPU was *formerly* known as Alder Lake, |
24 | was released in Q1 2022, but does not make it clear what it is now named as: |
25 | |
26 | 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 |
27 | |
28 | So, I'd be inclined to take their word for it. This Wikipedia lists the |
29 | processor as a mobile Alder Lake: |
30 | |
31 | https://en.wikipedia.org/wiki/Alder_Lake#Alder_Lake-H |
32 | |
33 | The Tiger Lake processors are 11th Gen and their model numbering start with |
34 | 11***. |
35 | |
36 | This page also confirms your family and model number as per cpuinfo use the |
37 | Golden Cove (P-cores) microarchitecture: |
38 | |

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