Apple M5 Max (128GB)

The Apple M5 Max (128GB) has 128 GB VRAM and 614 GB/s memory bandwidth. It can run 61 of our 81 tracked models natively in VRAM at 8k context.

With 128 GB LPDDR5X, the Apple M5 Max (128GB) is a laptop-tier GPU that can run 61 models natively. It handles 70B-class models at Q4 quantization.

The Apple M5 Max (128GB) is the flagship Apple Silicon configuration for local LLM inference, featuring 128GB of unified memory at 614 GB/s. It runs Qwen 3.6 35B and Gemma 4 31B entirely in-memory at F16 precision with room to spare, and can hold multiple models simultaneously for switching workflows without reload. With an 18-core CPU and full support from MLX and llama.cpp, the M5 Max (128GB) is the definitive on-device AI platform for Mac.

Apple M5 Max (128GB): 2026 flagship Apple Silicon laptop chip — 128GB unified LPDDR5X at 614 GB/s, 18-core CPU (6P+12E).

Runs models like Qwen 3.6 35B and Gemma 4 31B entirely in-memory at F16 with room to spare, and can hold multiple models loaded simultaneously. ~20-30 t/s for 7B via MLX.

MLX and llama.cpp Metal fully optimized. The highest-capacity single-chip Mac configuration for local LLM work, at a laptop power envelope.
