Can I Run Nemotron 70B on Apple M1 Max?
Written by Jakub Rusinowski · Last updated September 29, 2026
Yes, but it's tight — Nemotron 70B Instruct at Q4_K_M needs 46.1 GB at 8K context (42.6 GB weights + 3.5 GB KV cache/overhead), leaving ~1.9 GB of the Apple M1 Max's 48 GB usable memory, at ~5 tok/s (est.), with room for up to 8K context.

Nemotron 70B Instruct on the Apple M1 Max: VRAM by quantization

| Q4_K_M | 46.1 GB | ✓ Yes | 8K | — |

| Q2_K | 26.7 GB | ✓ Yes | 64K | — |
Assumes an 8K-token context with an f16 KV cache. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 64 GB of unified memory. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the Apple M1 Max: 8K 46.1 GB · 32K 54.2 GB ✗ · 125K 85.4 GB ✗. Past 32K it no longer fits 64 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? Nemotron 70B Instruct on 256 GB of system RAM, CPU only: runs, but too slowly to be worth it.
