# Supported Hardware Platforms

SecretVM currently supports two leading Confidential Computing platforms for CPU instances, allowing the developers maximum flexibility.

* **Intel TDX** 

  Intel TDX (Trust Domain Extensions)is a confidential-computing extension of Intel’s SGX lineage that brings hardware-enforced isolation and attestation to full virtual machines; it was introduced with 4th-generation Intel Xeon Scalable (“Sapphire Rapids”) processors. Intel TDX was publicly introduced in 2021, and was first widely available in 2023

* **AMD SEV-SNP**&#x20;

  AMD SEV-SNP (Secure Encrypted Virtualization – Secure Nested Paging) is AMD’s confidential-computing technology for full virtual machines, adding memory encryption *and integrity protection* against malicious hypervisors; it is available on AMD EPYC “Milan” and newer processors and widely deployed in production clouds. AMD SEV-SNP was announced in 2020 and first shipped with AMD EPYC "Milan" CPUs in 2021. AMD SEV-SNP is an exension of earlier AMD SEV technology, introduced in 2016 and first available with AMD EPYC "Naples" in 2017.

SecretVM also supports Confidential Computing on GPUs using NVIDIA Confidential Computing, currently available on the following devices:

* H100 (SXM & PCIe)
* H200
* GH200 Grace Hopper Superchip

NVIDIA Confidential Computing docs are available here: <https://www.nvidia.com/en-eu/data-center/solutions/confidential-computing/>

Currently, NVIDIA Confidential Computing is only available with Intel TDX CPUs. Adding support for AMD  is planned for Q2 2026.
