Which should you choose?
- • You want the newer architecture and longer driver support lifecycle
- • Faster token generation is the priority
- • You're on macOS and want native Metal acceleration (MLX, llama.cpp)
Frequently asked questions
- Which is better for local AI, the AMD Strix Halo (128GB) or Apple M4 Max (128GB)?
- For local AI inference, the Apple M4 Max (128GB) has the edge. It offers 128 GB VRAM (vs 128 GB) and 546 GB/s bandwidth (vs 256 GB/s), letting it run 61 models natively in VRAM vs 61 for its rival.
- How much VRAM does the AMD Strix Halo (128GB) have vs the Apple M4 Max (128GB)?
- The AMD Strix Halo (128GB) has 128 GB of LPDDR5X at 256 GB/s. The Apple M4 Max (128GB) has 128 GB of LPDDR5X at 546 GB/s. Both GPUs have the same VRAM amount; bandwidth determines which generates tokens faster.
