AMD has always been making underrated and solidly high-performing processors. fanboys can scream Apple or Intel and will never switch. I have all 3 brands and know from years of experience, that it's unfortunate that you can't fix stupid. You can say one thing that's incorrect, even if several billion people agree, it is still wrong.

The lead for the Ryzen is actually much greater, as it easily scores over 34K in CB R23 (I even saw one 36K benchmark).

Yes and you can undervolt and/or overclock it too, Notebookcheck concluded that the 7945HX is more efficient than both the M2's. Apple is in shambles.

Anon, The only advantage they have is battery life. The Ryzen 9 7945HX gets less than 4 hours. Even if x86 CPUs were able to get the battery life of Macs, the people that use Macs probably wouldn't switch over because of Apple's brand image.
