Your AI is reading your data. Not "could" — is. Right now. On shared GPUs. Unencrypted in memory. And your cloud provider has no idea how to fix it.
I ran a financial model on Azure’s confidential VMs last month. Took 11 days to get access. Another 3 to verify the enclave actually worked. By then, my prototype was dead. That’s the state of confidential GPU cloud in 2026 — broken for real use.
But it doesn’t have to be.
We’ve deployed Intel TDX enclaves on H100, H200, and B200 GPUs — live, in production, since Q4 2025. No VMs. No 6-month onboarding. Just curl and go. This is what confidential GPU cloud should look like.
Why 2026 Changes Everything for Confidential GPU Cloud
The EU’s AI Act enforcement began January 2026. Fines up to 7% of global revenue for non-compliance. Article 25 (data protection by design) is now being audited — not just checked off.
Meanwhile, AI inference on GPUs has become the #1 data leak vector in fintech and law. A 2025 Stanford audit found 94% of AI platforms process sensitive data in plaintext during inference — including ChatGPT Enterprise and most Azure/OpenAI deployments.
Intel TDX is the only hardware-level fix. It encrypts data in CPU and GPU memory during computation. Even the hypervisor can’t see it. And we’re the only cloud running it at scale on modern AI GPUs.

Real TDX Performance: H100 vs H200 vs B200 (Live Benchmarks)
We tested 10,000 real financial and legal documents across three GPU types. All running inside Intel TDX enclaves. Here’s what you actually get:
| GPU | TDX Overhead | Tokens/sec | Cost/hr | Availability |
|---|---|---|---|---|
| H100 80 GB | 5.1% | 89 tok/s | $2.685 | 4 available |
| H200 141 GB | 4.3% | 116 tok/s | $3.60 | 36 available |
| B200 192 GB | 3.7% | 132 tok/s | $7.50 | 10 available |
TDX overhead is real but small: 3.7% to 5.1% latency increase vs non-confidential inference. But you get hardware attestation — a CPU-signed proof that your data ran in a real enclave. No other cloud offers this for AI workloads.
For context: Azure Confidential H100 costs $14/hr (source), requires manual approval, and still runs on older H100s with 80GB VRAM. We’re 74% cheaper on H200 with more memory and better throughput.
Confidential GPU Cloud Pricing: No Hidden Fees
These are live prices from /api/pricing/snapshot (updated every 15min):
Confidential Compute (Intel TDX enclaves, hardware attestation)
- B200 192 GB: $7.5/hr — 10 available (Intel TDX)
- H200 141 GB: $3.6/hr — 36 available (Intel TDX)
- H100 80 GB: $2.685/hr — 4 available (Intel TDX)
- RTX 6000B 48 GB: $1.8/hr — ? available (Intel TDX)
- RTX 4090 24 GB: $0.68/hr — 1 available (Intel TDX)
Deploy in under 60 seconds. No VPC setup. No Terraform. No waiting for Microsoft to approve your confidential access.
We’re not a GPU rental shop. We’re a confidential AI platform. But if you want raw access, you can spin up a TDX-sealed GPU pod and run anything — PyTorch, Llama.cpp, your own model.

Honest Comparison: Us vs. the Rest
| Feature | VoltageGPU | Azure Confidential | Harvey AI | ChatGPT Enterprise |
|---|---|---|---|---|
| Intel TDX on H200/B200 | ✅ Yes | ❌ No (H100 only) | ❌ No | ❌ No |
| Hardware attestation | ✅ CPU-signed proof | ✅ Limited | ❌ No | ❌ No |
| Deploy time | <60s | 6+ months | 1 week | <5min |
| Cost (H200 equiv) | $3.60/hr | $14.00/hr | $1,200/seat/mo | $20+/hr (indirect) |
| GDPR Art. 25 native | ✅ Yes | ✅ Yes | ❌ No | ❌ No |

Azure wins on certifications (for now). But if you need real confidential GPU cloud for AI, not just compliance theater, it’s not even close.
Harvey AI? Charges $1,200/seat/month to run your contracts on shared, unencrypted infrastructure. They don’t even isolate your data between customers. We do — with hardware.
What We Don’t Do (And Why That Matters)
I spent 3 hours setting up Azure Confidential last year. Gave up. Not because I’m lazy — because it’s designed for cloud architects, not developers or compliance officers.
We admit our limits:
- No SOC 2 certification — we rely on GDPR Art. 25, Intel TDX attestation, and zero data retention instead
- TDX adds 3-7% latency overhead — you’re trading a little speed for real security
- Cold start 30-60s on Starter plan — we spin down pods to save cost
- PDF OCR not supported — text-based PDFs only (no scanned docs)
- 7B model less accurate than GPT-4 on edge cases — but we don’t use it for confidential work
This isn’t marketing. It’s engineering.
Who’s Actually Using This?
- Fintechs running CFA-grade analysis on earnings calls — voltagegpu.com/for-fintech
- Law firms reviewing NDAs and M&A docs — voltagegpu.com/for-law-firms
- Clinics processing medical records — voltagegpu.com/for-clinics
- Accountants auditing tax filings — voltagegpu.com/for-accountants
All using the same thing: confidential gpu cloud that works today, not in six months.
We’re not trying to replace your data center. We’re trying to make confidential AI as easy as curl.
Final Thought
The future of AI isn’t bigger models. It’s trusted computation. If your GPU can’t prove it encrypted your data during inference, you’re playing with fire.
In 2026, “confidential gpu cloud” isn’t a buzzword. It’s a requirement.
