The 7940HS is way faster than the M2. Efficiency is harder to compare since TDP doesn't mean anything theses days.
because even in cinebench the m3 max is already ahead in cinebench 2024 let alone R23...

The M3 max is on TSMC N3B, which have a +30% of transistor density compared to the TSMC nodes AMD is using (N4).
