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 the NVIDIA DGX Station. 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.
Exxact Valence DGX Station
- One of the few GB300 workstations with a public starting price. The starting configuration excludes drives, the optional display GPU and support options; the configurator sets the final price.
- Same GB300 superchip, memory and networking as every DGX Station; the chassis, cooling and warranty are Exxact’s.
- Supports one double-wide graphics card for display alongside the GB300.
