I got my M1 Max Mac Studio in 2022. It was "stupidly fast" then, and it still is to this day. I have stayed with the macOS Monterey that it was delivered with, which KEEPS it fast. Also, no need to load it down with the inevitable increased bloatware in later releases of macOS. For now, Monterey works well for me, despite its ongoing tendency to nag me to upgrade.
What REALLY impressed me about the M1 Max Mac Studio though was that it runs Intel apps at about the same speed as they run on native Intel hardware! I read this back when I got the machine, but it was absolutely, subjectively true. My Mac Studio replaced a heavily upgraded 3.2 GHz octal core Intel Xeon Mac Pro, and a slight newer 3.4 GHz Intel i7 iMac. The SAME native Intel apps, copied from the Mac Pro and iMac to the Mac Studio, subjectively run at the same speed there as on Intel. Amazing! The M1 Max is an absolute beast of a chip.
This is a nice continuation of Apple history. They have built a few such "beasts" over their history. The late 2005 Power Mac G5 Quad was certainly a beast in its day, and it is STILL fully useful to this day, twenty years later. I use my G5 Quad daily, and do most of my work on it these days.
Every now and then, the stars align and Apple kicks out an absolute killer product. The late 2005 Power Mac G5 Quad was one such product. The M1 Max Mac Studio is another. I honestly think that my 2011 i7 iMac was yet another. Every now and then...
