B300 Prices: category guide
Answer in brief
Runcrate is our editor’s choice for B300 prices: the best developer platform we know, billing by the second, and GPUs you can start now, in about four minutes.
A B300 price is quoted per GPU-hour, but many listings are for a machine of eight, and many cannot be started by a new account. Before you compare B300 prices, check three things: that you can start one today, how many GPUs you must take, and what unit you are billed in.
What a B300 price is a price for
The B300 is the newest NVIDIA datacenter GPU in these tables: a Blackwell Ultra card with 288 GB of memory. Providers quote it per GPU-hour. That unit lets a single card and a machine of eight sit in one column, and it hides which of the two you are looking at.
So read three things beside every B300 price. The smallest rental, because a per-GPU figure inside an 8-GPU machine is one eighth of the bill. The billing unit, because an hour you did not use on this card is real money. And the commitment, because only on-demand prices compare. On 12 Nov 2026, the lowest listed hourly total for an 8-GPU B300 machine was $52.80.
Why a listed B300 is often not for rent
A new card reaches a few providers first, in small numbers. Some sell out. Some hold their B300s for customers who talk to sales. Some give a new account no quota for it. The price on the page is the same in all three cases.
That is why every B300 row on this site carries a label and the day it was checked: Start now, No GPUs, Gated, Quota or Not checked. A price you cannot start is not a price. Read the label first and the figure second.
Before you trust a B300 price
Work through the questions in this order. Each one removes options the next would have wasted time on.
- Can you start it today?
Every B300 listing here is marked Start now, No GPUs, Gated, Quota or Not checked, with the date of the check. Read the label before the price.
- Is it one GPU or a machine of eight?
Many B300 prices are per GPU inside an 8-GPU node. You pay for all eight, every hour the node is up.
- What unit are you billed in?
By the second, the minute or the hour, and on a card this expensive an hour rounded up is a real cost. Ask too whether booting is billed.
- Is it an on-demand price?
A reserved price needs a term, often paid ahead, and a spot machine can be taken back. Neither compares with an on-demand figure.
- Do you need 288 GB on one card?
If the model fits in 180 GB, a B200 is the card to price. Memory you do not fill is money spent on empty space.
- When was the price read?
B300 prices move as stock arrives and sells. Read the date beside the price before you rely on it.
