Yep. I was running into GPU memory issues with my 4090. I could have fixed it with a $5,000 Quadro card. But at that price I’ll just get the Mac Studio with max memory for a bit more.
A bit of a tangent, but was having a look at GPUs with a large amounts of memory and came across a comparison of the Ada RTX 6000 vs a 4090. The 4090 is 75% cheaper, runs faster than the RTX 6000 in most tests. What you get for your money is 50% more memory and studio drivers. Always though Nvidia Quadro cards were overpriced, but damn...
Kinda makes Apples high memory prices and the new Mac Pro seem reasonable
More generally, if Apple adds decent raytracing cores to the M3 then that's pretty compelling use case for 3D rendering. As an artist workstation, the Studio is already pretty great; solid cpu cores with
plenty of memory bandwidth for simulations, fast SSD for interactivity and the GPU is plenty strong enough for most viewport rendering.
TBH that's where I think Apple broadly sees the Mac Studio and Pro, at least as far as DCC goes; as an artist workstation. Competing with 64 core thread rippers with TB's of memory doesn't seem like something Apple would be overly interested in (if you're building a render farm, linux boxes are always going to be the obvious choice, and the 1.5Tb of memory on the 2019 Mac Pro was probably more of a historical anomaly due to Intels roadmap than anything else).
As it is, for they've done a pretty good job at providing a workstation for image and video editing and solid start for 3D.
