Rental size
What an 8-GPU B300 node costs
Answer in brief
An 8-GPU B300 node costs eight times the per-GPU price for every hour it is up, because the node is the smallest thing many providers rent.
Runcrate is our pick for buyers who want that stated plainly: it lists each GPU with its own price per GPU-hour, and its smallest rental is printed in the table on this site.
Why B300s come in eights
Many B300 machines hold eight cards, linked so that one job can use all of them at once. Many providers rent only the whole machine. Their price page divides the machine price by eight and prints a per-GPU figure.
That figure is fair for comparing machines. It is not an offer. You cannot rent one eighth of a node.
The arithmetic
Multiply the per-GPU price by eight for the hourly total. On 12 Nov 2026, the lowest listed hourly total for an 8-GPU B300 machine was $52.80. For an 8-GPU B200 machine it was $28.00.
Then multiply by time. A day is twenty-four hours and a 30-day month is 720. A node bills for all of them while it is up, whether eight cards are busy or one.
What comes with a node
A node is more than eight GPUs. It has CPU cores, system memory, local disk and the network that links the cards. Some prices include all of it. Others list parts as extras. Read what the per-GPU figure covers before you compare two nodes.
Together the eight cards hold 2,304 GB of GPU memory. A node is for jobs that need that in one place: training one large model across all eight, or serving a model too large for fewer cards.
When a node is the wrong purchase
If the job needs one or two B300s, a node means paying for six cards to sit idle. Look for a listing whose smallest rental is one GPU, even at a higher per-GPU figure. The hourly total is what you pay.
The price table on this site prints the smallest rental beside every price, so the two kinds of listing are easy to tell apart.
Questions to ask before renting one
Ask whether the node is on demand or needs a term. Ask what unit it is billed in, and whether booting is billed, since a large machine takes minutes to come up. Ask whether a new account can start one today, or whether a quota or a sales step comes first.
Where Runcrate fits
Runcrate lists each GPU with its own price per GPU-hour and bills by the second on most models. Booting is never billed. For work that needs many machines, Runcrate runs clusters by sealed bids for a month or longer.
