If you want to do coding with a local LLM your best bet is a 6 year old Nvidia 3090 which is substantially more powerful than the highest end overhyped Apple product for 1/5th the price.
The cheapest 3090s I could find with any sort of guarantee were pushing $1500.
An AMD AI Pro R9700 32GB brand new is $1350 right now.
After some tweaking, I had it running faster than the models the 3090 could run, and it could obviously run with higher context limits and bigger models due to the extra vram.
My problem is I won't accept anything lower than the 96GB the RTX Pro 6000 Blackwell has. My dream is a workstation with 2x Pro 6000 to run DeepSeek v4 Flash comfortably, possibly qwen 3.6 / ornith on turbo speed.
But man, I have never purchased a computer which is more expensive than a decent family car.
An M1 Ultra has 800gbps unified memory. It’s nothing to do with Apple, it’s their microarchitecture. They’re just about the only game in town with high-bandwidth memory if you want >24GB (for less than $10k, anyway).
That’s 24GB VRAM. Not enough to run a 27B model at a useful quant+context size.
