VT-d is a prerequisite for TXT, which has value to people who aren't using VMs or containers.
VT-d also enables device driver containment/isolation, again, which provides value to people not otherwise interested in VMs or containers.
- ece 9y agoI'm not sure I would phrase it that way, the two are relatively independent. If you're getting a business laptop, you're likely to get VT-d and TXT. The i7-4710HQ has VT-d and doesn't have TXT or vPro. https://ark.intel.com/products/78930/Intel-Core-i7-4710HQ-Processor-6M-Cache-up-to-3_50-GHz https://ark.intel.com/products/78930/Intel-Core-i7-4710HQ-Pr... TXT is more a part of vPro and provides bootup security, including drivers loaded at startup. Everyone doesn't need VT-d or TXT. Most BIOSes support some sort of signing if you bother to setup it up and verify that your kernel hasn't changed. Intel could have made vPro, TPMs and TXT open and available to everyone, regardless of VT-d, but that's how they chose to differentiate and make a little more money. Mom and pop need to settle for basic kernel signing instead of an open TPM module.
