NVIDIA Rubin Ultra: specs, VRAM and rental prices
NVIDIA Rubin Ultra: no public rental price listed. Specs from NVIDIA, prices as of Oct 29, 2026.
Vera Rubin Ultra is a future NVIDIA generation. NVIDIA’s developer blog of Mar 16, 2026 says it will first appear in a Kyber rack as a standalone NVL144 system, and describes an NVL576 option built from eight MGX racks with 72 Rubin Ultra GPUs each. NVIDIA prints no memory, speed, power or date for the chip in the pages cited, so none is shown.
Prices were last checked Oct 29, 2026. A listing not re-checked for 7 days is greyed and left out of every lowest-price figure; after 14 days it is removed from the page.

Rubin Ultra rental prices by provider
No provider currently lists a public per-GPU-hour price for the Rubin Ultra that the Census has been able to confirm, so there is no rental price to show. The specifications above are still NVIDIA’s own.
Price history
The history chart appears once there are two daily snapshots of an on-demand price. Tracking began Oct 15, 2026; there is no on-demand snapshot for this GPU yet.

How these prices are collected
- What counts
- Only prices a provider publishes on a public pricing page or in its public price list, opened by the Census on the day shown. A marketplace is listed under the same rule as every other provider: it must publish per-GPU-hour prices publicly, with no login, and its rows are shown with the type Marketplace. Quotes and “contact sales” rows are not listed, and neither are purchase prices.
- $ per GPU-hour
- The listed price per GPU-hour. Where a provider lists a price per instance, the Census divides it by the GPUs in that instance and shows the original figure under it. Nothing else is converted or estimated. Google TPUs and AWS Trainium and Inferentia chips are priced per chip-hour on the same terms, with “chip” in place of “GPU”.
- Pricing types
- On-demand, spot (including tiers a provider calls preemptible or low-priority), reserved with the term the provider states, and marketplace. Reserved rows without a stated term are not listed. A marketplace row is the lowest per-GPU-hour price its public page shows for that GPU, which comes from third-party hosts and changes often. Marketplace rows are a separate type: they appear in the table, filters, downloads and feeds, but never in the “lowest on-demand” or “lowest spot” figures.
- Variants
- SXM, PCIe, NVL and similar versions are kept separate when the provider names them. A provider that does not name the variant is shown without one.
- Freshness
- Every listing carries the date it was last confirmed, and the daily run re-opens each one. If a listing goes 7 days without a re-check it stays on the page greyed, labelled with the date it was last confirmed, and drops out of the “lowest” figures and the calculator’s default results. At 14 days without a re-check it is taken off the site; the daily history still holds it.
- History
- Each daily run saves a snapshot, so the model pages can chart the lowest listed on-demand price over time and the change log can show what moved. History began Oct 15, 2026.
- Differences between providers
- Listed prices are not like for like: regions, minimum instance sizes, networking, storage, commitments and availability differ and are not priced here. Check the provider before relying on a figure.
Providers checked but not listed
- Vast.ai: Its pricing page loads live "from" prices from a public JSON file whose terms allow display and citation with attribution but require a data license for bulk collection, redistribution or use in any index, benchmark or derivative product. The Census republishes prices as open data, so it does not list Vast.ai without that license.
- Voltage Park: Its pricing pages say "Contact for pricing" for every GPU; one homepage line says "Starting at $1.99/hr" without a GPU model or unit.
Rubin Ultra: common questions
What is in the Rubin Ultra?
NVIDIA lists the configuration as NVL576: eight MGX NVL racks, each with 72 Rubin Ultra GPUs, in one NVLink domain.
How much does it cost to rent a Rubin Ultra per hour?
No provider currently lists a public per-GPU-hour price for the Rubin Ultra that the Census has been able to confirm, so no rental price is shown.
Can I rent a Rubin Ultra by the hour?
Not at a public price the Census can confirm. No tracked provider lists a public per-GPU-hour price for the NVIDIA Rubin Ultra right now. The Census adds a price as soon as a provider publishes one on a public page or price list.
Which architecture is the Rubin Ultra built on, and when was it announced?
The NVIDIA Rubin Ultra uses the Vera Rubin Ultra architecture and was announced or launched in 2026, according to the NVIDIA page cited in the specifications.
