Well Ada is essentially rebuffed Ampere with a new node, enhancements and a crap load of cache added. Blackwell is going to be a lot different as architecture goes (supposedly) so I think they'd keep power consumption to a reasonable level. As in I can't see them going over 500W for the 5090.
3nm and IPC gains from a new architecture will give them enough power jump in two years. And if, (and thats a big if) AMD somehow manages a pul a rabbit out the hat with RDNA 4. They can crank up the clocks.
On AMD. RDNA 3 is just trash architecture and in a lot of ways a half step forwards in efficiency. They obviously goofed up somewhere before launch and clearly missed their design targets; going by their launch promo graphs and actual performance targets. If AMD can sort out how to do a GPU with GCX and MCD's and hit performance targets, without massive power draw in RDNA 4 it could be interesting. Though with AMD's RTG, they've been underdelivering for years so not holding much hope there.
