Sizing GPUs for 70B-Class LLM Inference: Memory, Throughput, Architecture, and Cost
For most 70B-class dense LLMs, the practical GPU choice is determined less by raw compute than by memory headroom for weights, KV cache, and concurrency. A single 80GB GPU can serve a heavily quantized deployment, but BF16 or FP16 inference usually needs multi-GPU tensor parallelism or a larger-memory accelerator. The correct answer depends on quantization, […]
