That's great, like the ai ryzen max 395, apple silicon chips are also more energy efficient for llm (or gaming) then nvidia.

For 4 bit deepseek-r1-distill-llama-70b on a Macbook Pro M4 Max with the MLX version on LM Studio: 10.2 tok/sec on power and 4.2 tok/sec on battery / low power

For 4 bit gemma-3-27b-it-qat I get: 26.37 tok/sec on power and on battery low power 9.7

It'd be nice to know all the possible power tweaks to get the value higher and get additional insight on how llm's work and interact with the cpu and memory.



Interesting benchmarks, thanks for sharing!

If you're optimizing for lower power draw + higher throughput on Mac (especially in MLX), definitely keep an eye on the Desloth LLMs that are starting to appear.

Desloth models are basically aggressively distilled and QAT-optimized versions of larger instruction models (think: 7B → 1.3B or 2B) designed specifically for high tokens/sec at minimal VRAM. They're tiny but surprisingly capable for structured outputs, fast completions, and lightweight agent pipelines.

I'm seeing Desloth-tier models consistently hit >50 tok/sec on M1/M2 hardware without needing active cooling ramps, especially when combined with low-bit quant like Q4_K_M or Q5_0.

If you care about runtime efficiency per watt + low-latency inference (vs. maximum capability), these newer Desloth styled architectures are going to be a serious unlock.

Which benchmarks are you working off of, exactly? Unless your memory is bottlenecked, neither raster or compute workloads on M4 are more energy efficient than Nvidia's 50-series silicon: https://browser.geekbench.com/opencl-benchmarks


NVIDIA GeForce RTX 5090 - 376224 - 400-550W for gpu + 250-500W for cpu/ram/cooling/etc.

Apple M3 Ultra - 131247 - 200W [1]

Looks like it might be 2.8x faster in the benchmark, but ends up using 3.25x more power at a minimum.

Thank you for the numbers

What have you used those models for, and how would you rate them in those tasks?


RPG prompts works very very well with many of the models, but not the reasoning ones because it ends up thinking endlessly about how to be the absolute best game master possible...


Great use case. And very funny situation with the reasoning models! :)


How does mlx compare with the llama.cpp backend for LM Studio?
