Ryzen AI Max+ 395 64GB

AMD · 48 GB LPDDR5X · 215 GB/s · 120 W · MSRP $1,500

The Ryzen AI Max+ 395 64GB is a AMD accelerator with 48 GB LPDDR5X and about 215 GB/s peak memory bandwidth. AI Hashrate estimates local LLM decode (batch 1) at 8K context: fit counts weights + KV cache + 1 GB runtime overhead — not weights alone. At Q4, about 41 curated models fit fully on this card; at FP16, about 23 fit. Top Q4 speeds: MiniCPM5-1B ≈ 126.7 tok/s (estimated, fits); Qwen3.5-2B ≈ 68.4 tok/s (estimated, fits); DeepSeek-R1-0528-Qwen3-8B-layer-mix-bpw-3.8-mlx ≈ 59.5 tok/s (estimated, fits); Qwen3.6-35B-A3B ≈ 45.6 tok/s (estimated, fits); Qwen3.5-35B-A3B ≈ 45.6 tok/s (estimated, fits). Relative ranking is more reliable than absolute tok/s. See methodology for the bandwidth formula and measured-anchor policy. Methodology.
