Intel to phase out SGX after Xeon Diamond Rapids in favor of TDX

What happened

Just five years after bringing its Software Guard Extensions (SGX) technology to its mainstream server platform, Intel on Friday announced plans to discontinue its support after its upcoming Xeon 'Diamond Rapids' CPUs (the general-purpose processor at the centre of a computer) and concentrate its confidential computing efforts on Trust Domain Extensions (TDX). The company will continue to support existing SGX-enabled platforms into the early 2030s, but at the same time will expand TDX capabilities to address emerging requirements of cloud computing, enterprise workloads, and agentic AI applications. Intel is a semiconductor and electrical company based in Santa Clara.

Intel set to discontinue SGX after Xeon 'Diamond Rapids' and focus on expanding TDX capabilities to meet emerging security requirements of cloud computing, enterprise workloads, and agentic AI. Without a doubt, data sovereignty requirements are an increasingly important factor as organizations seek to protect sensitive information from unauthorized access even when they process it on infrastructure operated by third parties.
