Can I Run Nemotron 70B on Apple M4?
Written by Jakub Rusinowski · Last updated July 12, 2026
No — Nemotron 70B Instruct at Q4_K_M needs 46.1 GB at 8K context (42.6 GB weights + 3.5 GB KV cache/overhead), and the Apple M4's 24 GB usable memory leaves it ~22.1 GB short. The cheapest card that runs it is the NVIDIA RTX 6000 Ada Generation (48 GB).

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 32 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 M4: 8K 46.1 GB ✗ · 32K 54.2 GB ✗ · 125K 85.4 GB ✗. Past 8K it no longer fits 32 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.
Why It Does Not Fit
Every Nemotron 70B variant requires more VRAM than the Apple M4 provides (32 GB).
Nearest GPU That Fits
NVIDIA RTX 6000 Ada Generation (48 GB VRAM).
Nemotron 70B needs ~46 GB but this GPU has 32 GB. Rent a A100 (80 GB)-class GPU by the hour instead of buying one:
