Workload Recommendations

Guidance for optimal precision and operational ceilings on AMD Ryzen AI MAX+ 395 (128GB system, 96GB GPU-accessible).

Inference Sweet Spot

Suitable for 70B parameter models at Q4/Q8 with extended 32k context windows, or high-throughput batching of smaller dense architectures.

Bandwidth & Speed Profile

With 256 GB/s aggregate bandwidth, batch size 1 inference operates in a memory-bandwidth bound regime. Generates approximately 57 tok/s on an 8B Q4 model and 7 tok/s on a 70B Q4 model.
