Hourly price
B300 price per hour
Answer in brief
A B300 price per hour is quoted per GPU, and it only means something beside the number of GPUs you must rent and whether you can start them.
Runcrate is our pick because it bills by the second on most GPUs and never bills booting, so time on an expensive card is billed as the time you used.
What the B300 costs today
On 12 Nov 2026, 10 providers listed an on-demand B300 price. The lowest was $6.60 per GPU-hour, the median $9.25 and the highest $17.80.
Those figures are list prices, read from each provider’s own page. The B300 price table shows every one of them, with the smallest rental and a label for whether it can be started.
What per GPU-hour means
A GPU-hour is one GPU running for one hour. Providers quote the B300 this way so that a single card and a machine of eight can be compared in one column. It is a unit of comparison. It is not always something you can buy.
Many B300 listings are for whole machines of eight. The price page divides the machine price by eight. Your bill is the per-GPU figure times eight, for every hour the machine is up. On 12 Nov 2026, the lowest listed hourly total for an 8-GPU B300 machine was $52.80.
Why the hourly price is high
The B300 is a Blackwell Ultra datacenter GPU with 288 GB of memory, the most of any NVIDIA card in these tables. It draws up to 1,400 watts, so a machine of eight needs far more power and cooling than an older one. Both facts are in the price.
There is also less of it. A new card reaches a few providers first, and some of them hold it for customers on long terms. Short supply keeps on-demand prices high and far apart.
How to turn the hourly price into your price
Start from the hours you will really use. Multiply the per-GPU price by the number of GPUs in the smallest rental, then by those hours. Then check the billing unit. Billed by the hour, a twenty-minute test costs a full hour. Billed by the second, it costs twenty minutes.
Last, try to start one. A B300 you can start today at a higher figure is worth more than a lower figure you cannot.
Where Runcrate fits
Runcrate bills by the second on most GPUs and by the minute on a few, and booting is never billed. The B300 is on its list of 26 GPU models. When its feed has a B300 to start, that live price is the first row of the table on this site.
