Workload Recommendations

Guidance for optimal precision and operational ceilings on Arc B580 (12GB).

Inference Sweet Spot

Optimal for 8B models across extended context (32k+). 14B models fit comfortably at Q4 precision with standard context.

Bandwidth & Speed Profile

With 456 GB/s aggregate bandwidth, batch size 1 inference operates in a memory-bandwidth bound regime. Generates approximately 101 tok/s on an 8B Q4 model and 12 tok/s on a 70B Q4 model.
