FAQ & Reference

Frequently Asked Questions: Mistral Small 3 24B Instruct on Apple Mac Studio M3 Ultra (256GB Unified Memory)

How much VRAM does Mistral Small 3 24B Instruct need on Apple Mac Studio M3 Ultra (256GB Unified Memory)?

At standard 4-bit quantization (Q4_K_M) with 32K context, Mistral Small 3 24B Instruct requires 18.33 GB of total VRAM (weights + KV cache + CUDA runtime overhead).

What inference speed will Mistral Small 3 24B Instruct achieve on Apple Mac Studio M3 Ultra (256GB Unified Memory)?

Based on Apple Mac Studio M3 Ultra (256GB Unified Memory)'s 819 GB/s memory bandwidth, expected decode speed is approximately 35 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.
