The M3 strikes a very particular middle ground for AI of lots of RAM but a significantly slower GPU which nothing else matches, but that also isn't inherently the right balance either. And for any other workloads, it's quite expensive.
I have a Max M3 (the non-binned one), and I feel like 64GB or 96GB is within the realm of enabling LLMs that run reasonable fast on it (it is also a laptop, so I can do things on planes or trips). I thought about the Ultra, if you have 128GB for a top line M3 Ultra, the models that you could fit into memory would run fairly fast. For 512GB, you could run the bigger models, but not very quickly, so maybe not much point (at least for my use cases).
I think it actually is perfect for local inference in a way that build or any other pc build in this price range would be.
Apple’s Pro segment has been video editors since the 90s.
None of those will be true for any PC/Nvidia build.
It's hard to put a price on quality of life.
The pricing isn't as insane as you'd think, 96 to 256GB is 1500 which isn't 'cheap' but, it could be worse.
All in 5,500 gets you a ultra with 256GB memory, 28 cores, 60 GPU cores, 10Gb network - I think you'd be hard pushed to build a server for less.
