The S22 Ultra has really bad efficiency because it used either the 8gen1 or the Exynos 2200, and both were fabbed by Samsung, which is really bad. They're at least 3 to 4 gen behind Apple in terms of efficiency.
That is changing thanks to TMSC. 8+gen1 made a jump, making it only 1 or 2 gen behind Apple interns if efficiency. TMSC fabbed 8gen2 made another leap forward, pretty much neck and neck with the A15 in efficiency, and its GPU actually is showing better efficiency than the A16. Apple really needs 3nm if they still want to lead the efficiency race.
