GPU & Apple Silicon Comparison for LLMs

Every GPU and Apple Silicon device we track for local language-model inference, side by side. Compare VRAM, memory bandwidth, power draw, price, and the largest model each can run at Q4_K_M. Use the VRAM calculator to match a specific model to hardware.

Max model size assumes a dense model at Q4_K_M (params × 0.5 + 1.5 GB overhead). That column is a capacity ceiling, not a comfortable speed. Strix Halo rows repeat the practical fit under the device name: 128 GB at ~256 GB/s holds a slow dense 70B Q4 and large MoE quants, not a 200B-class interactive model. Mixture-of-Experts models use total parameters. Prices are indicative MSRP/street and set by the retailer. Full methodology.
