Workload Recommendations

Guidance for optimal precision and operational ceilings on NVIDIA RTX 3080 (10GB).

Inference Sweet Spot

Recommended for lightweight models (1B to 3B) at FP16/Q8, and 7B/8B models at aggressive 4-bit quantizations.

Bandwidth & Speed Profile

With 760.3 GB/s aggregate bandwidth, batch size 1 inference operates in a memory-bandwidth bound regime. Generates approximately 169 tok/s on an 8B Q4 model and 20 tok/s on a 70B Q4 model.
