What Larger Models Can Each Run?

├────────────────────────────┼────────────────────────────┼────────────────────────────┤

└────────────────────────────┴────────────────────────────┴────────────────────────────┘
Key insight: The Mac's unified memory architecture lets it load a 40 GB model (like 70B Q4) into GPU memory because CPU and GPU share the same 48 GB pool. The Razer has a hard 24 GB VRAM ceiling — anything beyond that spills to CPU RAM over PCIe, which is much slower. For models ≤32B, the Razer wins on raw speed. For 70B models, the Mac may actually provide a smoother (though slower) experience because it avoids the CPU↔GPU data transfer penalty.
