M1 at presentation and my M1 Mini 16 GB were overwhelming.
M1 Max and Ultra not that much because of scaling issues caused by a too small cache.
M2 also looked like just adding a few cores and some overclocking with more heat
to bring a noticeable improvement of about 15% here and there.
And when A17 3nm came I also wondered why there are no architectural improvements
visible. Only slightly faster again but no more battery life in on iPhones or M3 in MBPs.
But in real life, Blender GPU rendering benchmarks, with M2 Max/Ultra’s better scaling
made the M2 Ultra twice as fast as M1 Ultra.
OK, this was just finally fixing the scaling problem, not a real improvement. But for me it
does not make sense to buy a reduced price M1 Ultra Studio, for a reduced price similar to
a current M2 Max, which has similar real world performance but newer WIFI and such things.
Same for M2 vs M3.
M1 Max and Ultra was a bad M1 deal, but M2 Ultra got finally a reasonable “workstation”.
M3 did not deliver the expectations of finally going 3 nm, which we honestly expected
already for the larger M1 SoCs already. CPU cores again not improved, just a few more
cores and maybe some extra heat again.
But M3 RT hardware acceleration, even in an Apple first generation release
(basically already a 2nd release, if you count in the fail of adding RT to A16/M2)
and Dynamic Memory, when supported or even optimized work really well and bring
a real advantage for M3s.
Overall M3 is a bit faster as usual but for GPU it looks like it is more something like
double as fast. M3 is basically finally the SoC I initially expected the larger M1s to be.
But what is more important for me that I have some trust that the hard Apple times from
2012-2020 are over, where they left power or pro users left in the rain with a trash can
that was disappointing at release and not upgraded but sold for the same price for
6 years.
Now it looks again like Apple offers upgrades and improvements as soon as available,
so you can buy/upgrade to a new Mac Pro mobile/desktop at any point you need one.
Yes, they will be better in a year or few months again, but at the moment you get
the best available and not only a shelf warmer.
