Mac Studio (M3 Ultra) vs Minisforum MS-S1 Max

Pros

• 819 GB/s unified memory bandwidth
• Very large unified memory pool holds models that exceed consumer VRAM
• Near-silent and power-efficient for the capability

Cons

• Outside the CUDA ecosystem — training and custom kernels are awkward
• Memory is fixed at purchase and cannot be upgraded
• Raw compute per pound trails a discrete GPU build

Pros

• 128GB unified memory in a mini-PC chassis
• Runs models that would otherwise need multiple GPUs
• Low power draw for the capability

Cons

• Memory is soldered — no upgrade path
• Token generation well below a discrete GPU
• Pointless for models that already fit in consumer VRAM
