Field notes

A chip never arrives alone — it ships inside a machine that decides how it's cooled, powered and networked, and lately those machines have been swallowing the data center whole. Watch one number as you browse: how many GPUs act as one. Eight was the standard for a decade. Now it's 72, and 576 is on the roadmap.

Start with these three

NG NVIDIA GB200 NVL72 The rack that forced liquid cooling on an entire industry — start here. NH NVIDIA HGX H100/H200 The default 8-GPU server of the boom. Understand this and you understand 'a server'. CC Cerebras CS-3 The heretic: one dinner-plate chip, one box, no rack of little servers at all.

Training & inference systems

12
NG NVIDIA GB200 NVL72 The rack that is the computer: 72 GPUs, one NVLink domain, 120 kW, liquid only. Shipping NH NVIDIA HGX H100/H200 The 8-GPU baseboard that defined the standard AI server. Shipping AH AMD Helios AMD's 2026 rack: 72 MI400-series GPUs on open standards (UALink + OCP). Announced AI AMD Instinct MI300X Platform AMD's 8-GPU answer to HGX — the OAM board with 1.5 TB of HBM. Shipping AT AWS Trn2 UltraServer 64 Trainium2 chips fused by NeuronLink — the block Rainier is built from. Shipping CC Cerebras CS-3 One wafer, one box: 23 kW around a single enormous chip. Shipping DP Dell PowerEdge XE9680/XE9712 The enterprise AI server franchise — from 8-GPU boxes to NVL72 racks. Shipping GT Google TPU Pods Google's unit of training: thousands of TPUs behind optical circuit switches. Shipping HC HPE Cray EX The exascale platform under Frontier and El Capitan. Shipping ND NVIDIA DGX B200 NVIDIA's own-brand Blackwell server: 8 GPUs, 1.4 TB of HBM, ~14 kW. Shipping ND NVIDIA DGX SuperPOD The turnkey supercomputer blueprint — from 32 to thousands of nodes.
