Hardware Selection¶
On this page, we will explain what hardware is needed to enable Intel TDX. This encompasses CPU requirements and DIMM requirements. In most cases, the infrastructure provider is responsible for selecting the appropriate platform hardware. Please talk to your OEM/ODM provider to receive a platform fulfilling the listed requirements.
CPU Requirements¶
To enable Intel TDX, one of the following processor families is required:
DIMM (i.e., main memory) Requirements¶
In this section, we present DIMM populations supported for Intel TDX across various CPU generations. In a multi-socket system, each populated CPU must follow the presented DIMM populations.
Note
The supported DIMM populations are presented for informational purposes only. Please refer to the OEM/ODM documentation of your system, as the specific platform implementation may vary.
4th Gen Intel® Xeon® Scalable Processor and 5th Gen Intel® Xeon® Scalable Processor¶
At minimum, all slot 0's of all Integrated Memory Controller (IMC) channels for all installed CPUs must be populated (i.e., 8 DIMMs per populated CPU socket, at least). DIMM population must be symmetric across IMCs.
