R1 Distill 70B at Q4\_K\_M needs about 50.2 GB, and the Mac mini M5 Pro 64GB has 48.0 GB usable. That figure is 64 GB of unified memory on the spec sheet, of which 48.0 GB is usable for weights and cache, at 307 GB/s memory bandwidth. A 70B DeepSeek-R1 distill on Llama. Memory need matches Llama 3.3 70B; it is not the full DeepSeek-R1\. These are estimates from [our formula](https://whatcanirunai.vercel.app/method/), not measured benchmarks.

Try other sizes in the [VRAM calculator](https://whatcanirunai.vercel.app/vram-calculator/) or see the [context length guide](https://whatcanirunai.vercel.app/context-length/). ## What to do instead * Run [R1 Distill 32B](https://whatcanirunai.vercel.app/models/deepseek-r1-distill-qwen-32b/) instead (23.8 GB at Q4). It is a different model, not a drop-in, but it does fit this machine. * To hold R1 Distill 70B at Q4, you need about 50.2 GB. The [MacBook Pro M5 Max 128GB](https://whatcanirunai.vercel.app/hardware/macbook-pro-m5-max-128/) has 96.0 GB usable ($6699 Apple list price, 14-inch M5 Max 18C CPU/40C GPU, 128GB/2TB). * Our estimate is only 2.2 GB over this machine’s usable memory, so a tighter quant or a shorter context may work in practice. We still mark it as a no under [the published formula](https://whatcanirunai.vercel.app/method/). * CPU offload can load the weights anyway, but it is slow. We do not publish an offload tokens/sec figure. * See the [best GPU for this model family](https://whatcanirunai.vercel.app/best-gpu-for/deepseek-r1/) and the [DeepSeek-R1-Distill-Llama-70B model page](https://whatcanirunai.vercel.app/models/deepseek-r1-distill-llama-70b/). ## Other hardware for R1 Distill 70B * [R1 Distill 70B on an RTX 4090](https://whatcanirunai.vercel.app/can-i-run/deepseek-r1-distill-llama-70b/rtx-4090/)Won’t fit * [R1 Distill 70B on an RTX 5090](https://whatcanirunai.vercel.app/can-i-run/deepseek-r1-distill-llama-70b/rtx-5090/)Won’t fit * [R1 Distill 70B on dual RTX 3090s](https://whatcanirunai.vercel.app/can-i-run/deepseek-r1-distill-llama-70b/dual-rtx-3090/)Won’t fit * [R1 Distill 70B on a Mac Studio 256GB](https://whatcanirunai.vercel.app/can-i-run/deepseek-r1-distill-llama-70b/mac-studio-m5-ultra-256/)Fits * [R1 Distill 70B on an RTX 3090](https://whatcanirunai.vercel.app/can-i-run/deepseek-r1-distill-llama-70b/rtx-3090/)Won’t fit ## Other models on a Mac mini 64GB * [Llama 3.3 70B on a Mac mini 64GB](https://whatcanirunai.vercel.app/can-i-run/llama-3.3-70b-instruct/mac-mini-m5-pro-64/)Won’t fit * [gpt-oss-120b on a Mac mini 64GB](https://whatcanirunai.vercel.app/can-i-run/gpt-oss-120b/mac-mini-m5-pro-64/)Won’t fit * [Qwen3-235B on a Mac mini 64GB](https://whatcanirunai.vercel.app/can-i-run/qwen3-235b-a22b/mac-mini-m5-pro-64/)Won’t fit * [Mixtral 8x22B on a Mac mini 64GB](https://whatcanirunai.vercel.app/can-i-run/mixtral-8x22b-instruct-v0.1/mac-mini-m5-pro-64/)Won’t fit * [GLM-4.5-Air on a Mac mini 64GB](https://whatcanirunai.vercel.app/can-i-run/glm-4.5-air/mac-mini-m5-pro-64/)Won’t fit ## Quick answers Can I run R1 Distill 70B on a Mac mini 64GB? No. R1 Distill 70B at Q4\_K\_M needs about 50.2 GB, and the Mac mini M5 Pro 64GB has 48.0 GB usable. How much VRAM does R1 Distill 70B need? About 50.2 GB at Q4\_K\_M, 87.2 GB at Q8\_0 and 163.3 GB at FP16, estimated for a \~4k context. How fast is R1 Distill 70B on a Mac mini 64GB? We do not estimate tokens/sec when the model does not fit. CPU offload is possible but slow. What context length can I use? The weights already do not fit, so longer context is not the limiting factor. --- Agent guide: https://whatcanirunai.vercel.app/llms.txt · JSON API: https://whatcanirunai.vercel.app/developers/
