2026 Blueprint for Super‑Scale AI Compute Centers: Architecture, Cooling, Power

As large‑scale foundation models reach trillions of parameters and industry‑specific models proliferate, the daily global AI token consumption continues to rise, and leading vendors now spend over 100 billion PFLOPS on a single training project. This pressure drives a fundamental redesign of AI compute centers slated for 2026.

The redesign follows three logical layers:

Scale‑out to Scale‑up + Scale‑out: Horizontal rack‑server farms give way to vertically‑tightly‑coupled supernodes. Each supernode expands from dozens of accelerator cards to an integrated design of 384–8192 NPU/GPU cards, raising the cluster’s linear acceleration ratio from less than 50 % to over 88 %.

Homogeneous GPU to Heterogeneous mix: Deployments shift from a single GPU pool to a heterogeneous pool of domestic NPUs, overseas GPUs, and ASIC inference chips. An intelligent scheduling platform matches tasks to the most suitable chip architecture, enabling separate pools for training, fine‑tuning, and inference workloads.

Centralized power & air cooling to cabinet‑level liquid cooling with green power: Data‑center power and heat management moves from room‑level supply and air cooling to cabinet‑level liquid‑cooling distribution combined with direct green‑energy supply. New high‑density AI compute facilities target a PUE of 1.10–1.15, effectively eliminating air cooling from AI‑specific room specifications.

Domestically, the “East‑Data‑West‑Compute” (东数西算) strategy has matured across eight major hubs. Regions such as Ningxia, Gansu, and Guizhou leverage abundant wind and solar resources to build green‑energy AI compute bases that handle offline training and data‑cleaning for eastern workloads. Meanwhile, the Yangtze Delta and Guangdong‑Hong‑Kong‑Macao regions are deploying 100‑k‑card top‑tier clusters focused on general‑purpose large‑model research, real‑time inference, and high‑latency‑sensitive AIPC cloud services, with cross‑region lossless compute‑network links entering commercial scale.
