Frequently Asked Engineering Questions (FAQ)
How much VRAM does Llama-3.1 70B Enterprise require in GPTQ 4-Bit Second-Order?
Uncompressed weights alone consume 35.0 GB. In addition, the KV cache scales with context tokens and concurrency batch size, plus ~1.8 GB CUDA driver overhead.
Can a single NVIDIA L40S 48GB Ada Lovelace run this model without Out-Of-Memory (OOM)?
If total weights + KV cache exceeds the 48 GB boundary, Tensor Parallelism (TP) or vLLM PagedAttention multi-GPU sharding across NVLink is required.
How does 4-bit quantization affect inference quality and speed?
Modern AWQ and GPTQ retain >98% perplexity compared to FP16 while halving memory footprint and doubling memory-bandwidth-bound token generation speed.
