Full Datacenter Rack
NVIDIA GB300 NVL72
72 GPUs, one rack, the top of the line — built to run the biggest models in the world.
Real NVLink Cluster
$6,500,000
NVIDIA has never published NVL72 rack pricing. Press estimates for GB300 NVL72 range $4M–$6.5M per rack depending on configuration (Tom's Hardware); we list the top of that reported range.
Specs, in plain words
| Total GPU Memory |
~20 TB (72 × 279 GB HBM3e)
20,000 GB pooled together — enough to hold several of the largest open models in the world at the same time, with room to spare.

| Power Draw |
135 kW sustained, up to 155 kW peak
135,000 watts. At about 1,200 watts per average home, that's roughly 112 homes' worth of continuous electricity — running one rack, 24/7.

| Interconnect |
NVLink switch fabric across the whole rack
All 72 GPUs are one tightly-wired system, not 72 separate computers — the gold-standard example of real clustering.

Power draw in everyday terms: 135.0 kW is roughly the same continuous draw as
112.5 average U.S. homes (about 1,200 W each) running around the clock.
Running this for one hour uses about 150.0% of a typical 90 kWh electric-car battery.
