Three Physical Walls Are Hitting AI Datacenter Infrastructure at the Same Time, and the Compound Effects Are Worse
The Next Platform, Friday, October 23rd, 2026
Rising chip power is breaking cooling, power delivery and interconnect at once; xFusion argues they must be co-optimized. Partner content.
Accelerator racks have climbed from about 20 kW in 2023 to 240 kW in 2026, with chips past 2,000 watts and megawatt-class racks in validation.
Recapping an xFusion keynote at the 2026 OCP Global Summit, the article argues this step change breaks cooling, power delivery and electrical interconnect simultaneously, and solving two while ignoring the third still strands infrastructure.
Air cooling is finished for high-density AI racks; xFusion's diamond-copper cold plates claim about twice copper's conductivity and more than 4,000 watts of single-chip cooling capacity.
