Only with offload — Qwen3.8 spills onto CPU/system RAM on the Apple M3 (24 GB), so expect a large speed penalty.

Apple M3 Specs

Qwen3.8 27B on the Apple M3: VRAM by quantization

VRAM needed assumes a 4K-token context with an f16 KV cache; “Max context” is the largest window that still fits in 24 GB of unified memory. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.

Why It Does Not Fit

Every Qwen3.8 variant requires more VRAM than the Apple M3 provides (24 GB).

Nearest GPU That Fits

NVIDIA GeForce RTX 5090 (32 GB VRAM).
