Frequently Asked Engineering Questions (FAQ)
How much VRAM does Llama-3.3 70B High-Efficiency require in GGUF Q4_K_M Medium Quant?
Uncompressed weights alone consume 39.4 GB. In addition, the KV cache scales with context tokens and concurrency batch size, plus ~1.8 GB CUDA driver overhead.
Can a single AMD Instinct MI300X 192GB run this model without Out-Of-Memory (OOM)?
If total weights + KV cache exceeds the 192 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.
