Questions people ask
What is a GB300 NVL72?
NVIDIA's Blackwell Ultra rack: 72 GPUs and 36 Grace CPUs, liquid-cooled and linked by NVLink. It has more memory per GPU than the GB200 NVL72.
Can I buy GB300 NVL72 racks here?
Tell us how many racks you need and where they'll run. We match you with sellers in our network, and you inspect the racks before you pay.
Can I sell GB300 racks before they're deployed?
Yes. We close deals on surplus and cancelled-order racks, deployed or not. Tell us what you have and where it is.
Can GPUs be sold to buyers outside the US?
Often, yes, depending on the destination and the end user. US export rules restrict where advanced GPUs can go, so every deal has a confirmed end user, screened against those rules, before any money moves.
