Can I Run Nemotron Cascade 2 on Apple M1?
Written by Jakub Rusinowski · Last updated September 11, 2026
No — Nemotron-Cascade 2 30B-A3B at Q4_K_M needs 21.7 GB at 8K context (19.1 GB weights + 2.6 GB KV cache/overhead), and the Apple M1's 12 GB usable memory leaves it ~9.7 GB short. The cheapest card that runs it is the NVIDIA GeForce RTX 5090 Laptop GPU (24 GB).

Assumes an 8K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 16 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: 8K 21.7 GB ✗ · 32K 27.1 GB ✗ · 128K 48.9 GB ✗. Past 8K it no longer fits 16 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.

Why It Does Not Fit
Every Nemotron Cascade 2 variant requires more VRAM than the Apple M1 provides (16 GB).
Nearest GPU That Fits
NVIDIA GeForce RTX 5090 Laptop GPU (24 GB VRAM).
Nemotron Cascade 2 needs ~22 GB but this GPU has 16 GB. Rent a RTX 4090 (24 GB)-class GPU by the hour instead of buying one:
