Apple M5 Max (128GB)

The Apple M5 Max (128GB) has 128 GB VRAM and 614 GB/s memory bandwidth. It can run 58 of our 70 tracked models natively in VRAM at 8k context.

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) is a mobile/laptop Apple Silicon chip based on the Apple M5 Max architecture. Released in 2026. It features 128 GB of LPDDR5X unified memory at 614 GB/s memory bandwidth. As an Apple Silicon chip, its memory is unified between CPU and GPU, so the full 128 GB can be allocated to model weights. MLX gives the best performance on Apple Silicon; llama.cpp Metal backend is a solid alternative. Both are well-supported by Ollama.

For local LLM inference, this GPU runs 58 of the 70 models we track natively in VRAM at 8K context. The largest model it handles in VRAM is DeepSeek V4 Flash 284B (157.9 t/s at Q2_K). It can run all tracked models including 405B-class frontier models entirely in VRAM. On Llama 3.3 70B Instruct, it achieves approximately 8.8 tokens per second at Q8_0 quantization.

Apple's Metal backend is fully supported by MLX and llama.cpp, giving excellent performance on macOS. Among laptop GPUs, it sits above Apple M4 Max (128GB) and Apple M3 Max (128GB) in performance, but below Apple M1 Ultra (128GB).
