I'm also a bit shocked by the Tigerlake mirror games:
- TGL 4+2 @ 9W on 7nm 10nm providing 2X productivity over AML 2+2 @ 5W on 14nm is not impressive at all --> you double the core count, essentially double the power budget for those cores and also have considerable power savings from 7nm 10nm to work with.
- TGL 25W offering 4X GPU perfomance over WHL 15W should also raise some eyebrows --> if we consider 5W CPU core usage during graphics workloads then we're already in a scenario where GPU power budget is being doubled even before 7nm 10nm power savings are factored in. In fact, if we look at the 2X improvement of ICL Gen 11 vs. WHL Gen 9.5, all we're left with is TGL 25W Xe offering 2X performance over ICL 15W Gen11. Cut that power in half and Xe advantage may come down to low double digit numbers.
