heyyy same, checkout kapitsa as the inference engine, gets 145+ tokens/sec

https://github.com/nace-ai/kapitsa

this machine just keeps getting better and better in the inference world. the memory bandwidth is too good, newer macbook pros aren't that much faster in memory bandwidth, many are slower. not enough to upgrade yet as they're mostly horizontal upgrades, the improvements in other areas are adding up like wifi bandwidth and protocol, NVMe speeds, webcam

if they do the M7 correctly: which is just everything their current models do plus way faster memory bandwidth and much greater memory possible 192GB+, then it will be a really great and timely upgrade

Has the webcam changed or improved in the last couple years? It seems to still have the same webcam specs as the M4?

Here are the numbers that got me buying a used M1 Max for LLM work.

    M1 Max 400GB/s
    M4 Pro 273GB/s
    M5 Pro 307GB/s
Only Max are worthwhile for LLMs. An Ultra is just two Mac chips on a die, but I think they're just used in Mac Studio.

I'll check it that inference engine! Thanks!

Edit: it doesn't give numbers for unsloth/Qwen-3.6-35B-A3B 4bit, but I'm using mlx-serve right now and getting petty good numbers (and it took a while to tweak everything properly!)
