Is the new Apple M5 actually worth it if all you care about is local LLM inference?

thinking about upgrading my M2 Max for local inference work (running 70B-class models comfortably, some local fine-tuning). The unified memory bandwidth improvements on M5 look solid on paper but I've learned to distrust Apple's own benchmarks for anything AI-specific. Anyone actually running real workloads on one yet, or should I just wait for the inevitable M5 Ultra Mac Studio?

wait for the ultra, every single time the base/pro/max chips get announced people rush to buy and then the ultra studio drops 4 months later and makes it look silly

memory bandwidth is genuinely the bottleneck for token generation speed on these chips, and yes the improvement is real, i've run quantized 70b models and its noticeably snappier than my M3

do you have actual tok/s numbers? curious how it compares to a used 4090 setup for the same model size

for pure inference a used 3090/4090 rig is still way more cost effective per token, apple silicon wins on power draw and silence, not raw price performance

the unified memory capacity is the real unlock though, running models that simply wont fit on consumer nvidia VRAM without serious offloading tricks

i went the mac studio route specifically because i wanted a quiet machine in my living room, the performance per watt argument genuinely matters for some setups

honestly the software ecosystem (MLX etc) maturing has done more for apple silicon LLM performance over the last year then the hardware jumps themselves

if you're doing any actual fine-tuning not just inference, nvidia's CUDA ecosystem still has way better tooling support, worth factoring in
