Intel says Diamond Rapids will be the last Xeon platform to include Intel Software Guard Extensions (SGX), as it focuses its confidential-computing roadmap on Intel Trust Domain Extensions (TDX). Intel describes TDX as a way to protect confidential virtual machines and containers across cloud and enterprise environments.
The roadmap change is not an immediate SGX shutdown. Intel says it will continue support and security updates for platforms with SGX into the early 2030s, giving customers several years to plan, validate and migrate. The company argues that virtual-machine isolation scales and deploys more easily for broad adoption; its post gives a broad support horizon rather than individual end-of-support dates.
