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.
NH
NVIDIA HGX H100/H200
The 8-GPU baseboard that defined the standard AI server.
AH
AMD Helios
AMD's 2026 rack: 72 MI400-series GPUs on open standards (UALink + OCP).
AI
AMD Instinct MI300X Platform
AMD's 8-GPU answer to HGX — the OAM board with 1.5 TB of HBM.
AT
AWS Trn2 UltraServer
64 Trainium2 chips fused by NeuronLink — the block Rainier is built from.
CC
Cerebras CS-3
One wafer, one box: 23 kW around a single enormous chip.
DP
Dell PowerEdge XE9680/XE9712
The enterprise AI server franchise — from 8-GPU boxes to NVL72 racks.
GT
Google TPU Pods
Google's unit of training: thousands of TPUs behind optical circuit switches.
HC
HPE Cray EX
The exascale platform under Frontier and El Capitan.
ND
NVIDIA DGX B200
NVIDIA's own-brand Blackwell server: 8 GPUs, 1.4 TB of HBM, ~14 kW.
ND
NVIDIA DGX SuperPOD
The turnkey supercomputer blueprint — from 32 to thousands of nodes.
SN
Supermicro NVL72 & 4U Liquid-Cooled Systems
The speed-to-market systems that built Colossus.
