Why there is no single answer to “which is cheapest”
Different GPU models deliver vastly different compute capabilities: the RTX 3090 is cheaper but only has 24GB VRAM and no NVLink—unsuitable for training large models; the H100 costs 3–4× more but features 80GB HBM3 and a Transformer Engine, delivering performance equivalent to several RTX 3090s on a single card.Select GPU model by task first, then compare prices within the same modelThis is the correct cost-saving sequence.
