Questions about AEX-notify support

Hello,

I found that AEX-Notify is supported on Intel 5th generation Xeon Scalable processors and earlier generations (via microcode updates).

I also heard that Intel SGX is deprecated on non-server processors, possibly on Core processors.

My questions are:

1. Do non-server processors lack support for AEX-Notify?

2. Do all earlier Xeon processors support AEX-Notify?

My desktop (w/ 10th Gen Core) has a recent microcode, but it seems that AEX-Notify is not supported.

I'm trying to determine which processors support AEX-Notify.

Thanks,

Hello.

In short, AEX-Notify was enabled on all Xeon branded CPUs, like Xeon E's, Xeon Scalables, etc.

As for which current, and more importantly future CPUs support SGX, please see this blog post. Specifically, see the section titled "The Road Ahead – Intel SGX and TDX".

Regards.
