Intel Stops SGX Support After Diamond Rapids Xeon CPUs
Intel has announced plans to discontinue support for Software Guard Extensions (SGX) after its upcoming Xeon 'Diamond Rapids' CPUs.
Intel will stop supporting Software Guard Extensions (SGX) after releasing its upcoming Xeon 'Diamond Rapids' CPUs. SGX isolates code and data within applications through hardware-protected enclaves. Developers must design or modify applications to use these protected enclaves, but Intel does not attribute this decision to security concerns.
The company will keep supporting existing SGX-enabled platforms until the early 2030s. Intel's Trusted Domain Extensions (TDX) technology separates entire virtual machines from the host environment, including the hypervisor and other VMs.
Key facts
- Intel ends SGX support after Diamond Rapids Xeon CPUs
- SGX isolates code/data within applications via hardware-protected enclaves
- Existing SGX-enabled platforms supported until early 2030s
