I just upgraded from 32GB to 96GB RAM. I was regularly in the red in terms of memory pressure because I run heavy IDEs, multiple Docker containers, iPhone and Android simulators, etc all at the same time. Definitely could've gotten by with 64GB, but I decided to go all out with this purchase and just max out the RAM.
 
software developer, using iMac 2020 128GB ram for years.

96GB + virtual ram will be enough
 
I upgraded because the 32mb TLB not allowing the full 400GB/s bandwidth in heavy workloads even if apps have native Apple Silicon support (not to mention battery life needed more improvement when under moderate stress).

Also, all my displays are 120hz; I use my computer to model, minor game development, and graphic design. RAM usage is always near full and create project limitations (especially for unoptimized apps).

Maybe we don’t have 3nm processors yet, but Apple definitely refined the I/O, cache, and GPU with substantial improvements.

I’m enjoying reading these responses. I have this weird desire to one day be able to max out a machine like you guys. I get by with 8GB. I’m merely a pleb amongst the company of titans.

I had a 2010 5,1 Mac Pro with 128GB. I did run an enterprise CMS (local instance) along with other things on it and the 128GB was useful.

I haven't upgraded the 7,1 yet due to unexpected expenses relating to injury and hospital. I will probably go up to 192GB for it and 2.5ghz 28 core Xeon.

Wondering the real world applications or benefits. Besides film who's using this?
For chess of course!!
I also use 512 GB RAM for chess.
Apple has not even managed to offer 128 GB RAM in the MacBook.
They just forgot about it.
Even the one year old Mac Studio has 128 GB RAM. The successor will probably have 256 GB RAM.
Only 96 GB RAM in the MacBook Pro is a joke.
Apple should have at least doubled the RAM.

Unless I am running experiments or running VMs I can get away with 64GB most of the time but typically I have 128GB on my main workstation, 256GB on my server. 32GB for desktop/productivity/research/studying/programming/design use? No chance, I am used to heavy multitasking since the 80s.
 
96GB is for people who eat at Salt Bae restaurants and order the golden tomahawk steak and only take 2 bites of it.

Heck yeah!! Go for it man. Aye, the good Macs of yesteryear — the ones that were actually upgradeable.

Hope you heal up and are back at it soon. :)
 
I'm 100% sure that the 64 GB I ordered will be enough. Well, I was until this thread :)

I am a developer. VM's were common for me, but will be less so in the future. Docker containers will be more the norm and they all share the underlying VM. If I have some memory constraints, I can offload some stuff to a Linux machine sitting in my office. But, I'm still second-guessing myself.

I had 128 in one of my 5,1s as well.
