Cloud GPU Pricing 2026: Confidential VM prices for H100, H200 and RTX PRO 6000 | VoltageGPU

Live VoltageGPU pricing for Confidential VMs with an NVIDIA H100, H200 or RTX PRO 6000 Blackwell GPU, side-by-side with AWS, Google Cloud and Microsoft Azure. Every VM is an Intel TDX trust domain with NVIDIA GPU attestation you generate and verify yourself, per-second billing, no commitment. Your first top-up of $10 or more adds one hour on the RTX PRO 6000 Blackwell VM.

Comparison prices are public list prices from each provider’s pricing page (April and September 2026). VoltageGPU prices are read live from the provider inventory and update on this page.

Two ways to use VoltageGPU

  • Confidential VM (Intel TDX, attestation generated by the tenant): RTX PRO 6000 Blackwell $3.80/hour, H100 $6.95/hour, single-GPU H200 $8.08/hour, each with the Intel TDX quote and the NVIDIA GPU attestation verified from inside the VM; 8x H100 node $55.62/hour with NVIDIA attestation of all eight GPUs (multi-GPU Protected PCIe mode, verified 10 September 2026). Self-service, boots in about two and a half minutes, one hour upfront then per second, unused time refunded on release.
  • Confidential AI inference API, OpenAI-compatible, every model in a TEE, billed per token from the same balance.

Also available: Standard GPUs with no enclave, for data that is not sensitive, from a distributed provider network at /standard-gpus, typically from under $0.50 per GPU-hour on the smallest cards. Confidential AI agents for regulated teams have their own page at /agents/confidential.

Why VoltageGPU

  • Per-second billing, pay for the exact second the machine runs, not for whole hours
  • No reserved-instance lock-in, no 1-year or 3-year commitments to unlock the listed price
  • Your first top-up of $10 or more adds $3.80, one hour on the RTX PRO 6000 Blackwell Confidential VM
  • Same Intel TDX confidential computing technology as Azure and Google Confidential VMs, with an open-source verifier and public dated evidence
  • Bitcoin accepted alongside card payments

Frequently Asked Questions, Cloud GPU Pricing

What is the cheapest confidential GPU per hour in 2026?

On VoltageGPU, the RTX PRO 6000 Blackwell Confidential VM at $3.80/hour, and an H100 Confidential VM at $6.95/hour. AWS p5 ($4.30/hr) and Google a3 ($3.67/hr) are commodity instances without a trusted execution environment, so they are cheaper per hour but not comparable; Azure’s confidential NCC40ads H100 v5 lists at $8.90/hr (12 September 2026).

How do VoltageGPU prices compare to AWS, GCP, and Azure?

The only hyperscaler SKU with a GPU inside a trust boundary and a public price is Azure’s NCC H100 v5 (AMD SEV-SNP plus one H100 NVL, $8.90/hr list on 12 September 2026); Google Cloud sells confidential H100 on A3 High with Intel TDX at per-zone rates, and AWS has no confidential GPU. Dated, sourced comparison: four clouds compared.

Is there a free trial?

Signing up is free. Using a machine needs a prepaid balance, and your first top-up of $10 or more adds $3.80 automatically, one hour on the RTX PRO 6000 Blackwell Confidential VM, once per account.

Is there a minimum commitment or reserved-instance discount?

No. The prices on this page are the price you pay, with no contracts and no reserved instances. Per-second billing means a five-minute experiment costs five minutes. Minimum top-up is $5.

How does VoltageGPU billing work?

The first hour is charged when the VM starts, then billing is per second; the unused part is refunded when you release the machine.

Confidential VM · Intel TDX · attestation by you

You generate the proofs, not us

A full Intel TDX virtual machine with root over SSH. /dev/tdx_guest is yours: you write your own report_data and read back a signed quote. On the single-GPU H200, H100 and RTX PRO 6000 Blackwell VMs, and per GPU on the 8x H100 node, the GPU adds its own NVIDIA-verified attestation, bound to a nonce you choose.

Two ways to run confidential AI: a Confidential VM or the confidential inference API. Every figure on this page is read from the provider inventory a few minutes ago, and on a VM the unused part of the first hour comes back to your balance when you release.

One hour charged upfront, then per second; the unused part is refunded on Release. No persistent volume on this tier: the disk is destroyed with the machine, copy your results off before you release. See the two proofs, measured.

Azure's confidential ND H200 v5 lists at $13.96/h for the same Intel TDX hardware.
