Architecture & Throughput Transparency: Single-user decode speed (~1 tok/s) is memory-bandwidth bound at batch size = 1 on Apple Mac Mini M4 (24GB Unified Memory) (120 GB/s). Prompt prefill / TTFT (~15 tok/s) is compute-bound and utilizes GPU Tensor cores. Actual latency varies with FlashAttention-2 and runtime engine (Ollama/vLLM/llama.cpp).

FAQ & Reference

Frequently Asked Questions: DeepSeek-R1 Distill Qwen 32B on Apple Mac Mini M4 (24GB Unified Memory)

How much VRAM does DeepSeek-R1 Distill Qwen 32B need on Apple Mac Mini M4 (24GB Unified Memory)?

At standard 4-bit quantization (Q4_K_M) with 32K context, DeepSeek-R1 Distill Qwen 32B requires 25.41 GB of total VRAM (weights + KV cache + CUDA runtime overhead).

What inference speed will DeepSeek-R1 Distill Qwen 32B achieve on Apple Mac Mini M4 (24GB Unified Memory)?

Based on Apple Mac Mini M4 (24GB Unified Memory)'s 120 GB/s memory bandwidth, expected decode speed is approximately 1 tokens per second.

Can I expand context beyond 32K tokens?

Each additional 32K tokens of context requires additional KV cache memory. For longer context windows, consider 8-bit or 4-bit KV cache quantization.
