NVIDIA's Blackwell chip brings an AI hardware revolution: shifting from air cooling to liquid cooling, with single-rack weight increasing from 1,000 lbs to 3,000 lbs and power consumption rising from 30kW to 130kW (equivalent to the electricity usage of 130 American households). This transformation is extremely complex, akin to "needing to renovate your home's electrical circuits just to upgrade to a new iPhone." Previously, Google temporarily held the position of "lowest-cost token generator" with its TPUs, squeezing competitors with a 30% negative profit margin. But as Blackwell scales (the first model is expected to launch via xAI in 2026), combined with the adoption of the more compatible GB300 chip, NVIDIA will reshape cost structures, forcing Google to adjust its strategy. This battle over computing power costs is profoundly redrawing the AI economic landscape.
