Workload Recommendations

Guidance for optimal precision and operational ceilings on Radeon PRO W7800 (32GB).

Inference Sweet Spot

Optimized for 14B models at uncompressed or Q8 precision, and 32B models at Q4 with up to 32k context.

Bandwidth & Speed Profile

With 576 GB/s aggregate bandwidth, batch size 1 inference operates in a memory-bandwidth bound regime. Generates approximately 128 tok/s on an 8B Q4 model and 15 tok/s on a 70B Q4 model.
