Rent or buy an RTX 4090

A bought card has a price, and then it has running costs. An RTX 4090 draws up to 450 W under load. It needs a machine around it, cooling, and someone to keep it working.

It also ages. The RTX 5090 has already followed it, with 32 GB on the newer Blackwell generation. The card you own today is the card you have next year.

A rented card costs the hourly price for the hours it is on, plus storage. There is nothing to resell and nothing to repair. When you stop the machine, the GPU cost stops.

On 12 Nov 2026, the median listed on-demand RTX 4090 price here was $0.435 per GPU-hour.

Divide the price of the card and its machine by the hourly rental price. The result is the number of busy hours at which buying matches renting, before power. Then ask how many months it takes you to use that many hours.

At a few hours a day, the answer is a long time. At twenty-four hours a day, it is short. If the answer is longer than you expect to want this card, rent.

Rent when your need is uneven, when you are still choosing between cards, when you need several cards for one week, or when the job may outgrow 24 GB. Renting lets you change your mind for the price of an hour.

Buy when one card will be busy most of every day for a long time, you have somewhere to run it, and 24 GB will still be enough at the end. Even then, compare with a prepaid rental term, which lowers the hourly figure without the hardware.

Runcrate rents by the second on most GPUs with booting never billed, and a machine can be prepaid for 1 to 12 months at a discount. Its list runs to 26 GPU models from $0.23/hr, so the next card up is on the same account.
