Open the recordWhat actually differs
- Same GB300 platform. Model recipes carry over; the real differences are chassis, storage, cooling, support and price.
- Both expose 252 GB to models (496 GB CPU + 252 GB GPU · 748 GB coherent vs 496 GB CPU + 252 GB GPU).
- Same memory bandwidth (7100 GB/s), so the same decode ceiling for a model that fits on both.
- No public list price in the record for either machine. Ask the supplier for a configured quote.

Before you choose
NVIDIA DGX Station
- 748 GB coherent memory is 252 GB HBM3e on the GPU plus 496 GB LPDDR5X on the CPU, joined by NVLink-C2C. The two tiers have very different bandwidths; large models spill from the fast tier into the slow one.
- NVIDIA does not sell the DGX Station directly: it is ordered through partner manufacturers, each with its own chassis, drives, warranty and price. Partner listings observed in 2026 ran from about $85,000 to $175,000 depending on configuration.
- NVIDIA specifies 1,600 W total system power and a 20 A circuit. Confirm OEM and regional installation requirements before choosing an office outlet. The GB300 can be paired with an RTX PRO 6000 Blackwell workstation GPU for graphics and additional compute.
ASUS ExpertCenter Pro ET900N G3
- 252 GB GPU and 496 GB CPU memory are coherent but do not have equal bandwidth.
- The manufacturer specifies two pre-installed 2 TB OS drives. Confirm usable RAID capacity and optional data drives.
