Single-core is about same across chips of the same generation. In my experience you need at least a 50% increase in CPU performance to notice it outside of compute tasks. Obliterate is a strong word for “acceptable increase”.Have to say that's pretty impressive. Here I am with a two year old Mac Studio Max whose single-core GeekBench score of 2406 is already obliterated by a fanless a Macbook Air
The bigger issue on the Mac side is that the system is still very much held back by lack of parallelization. Few would notice the difference between an M and M Ultra.
