Does the Xeon 5th still have the user interrupt(UINTR) feature?

[yyi]

I want to check if the Xeon 8592+ processor I'm considering purchasing includes the UINTR (User Interrupt) feature introduced by Intel in the 4th Gen Sapphire Rapids architecture. The purchasing page for the processor doesn't provide this information, but:

1. I found a document stating that the 5th Gen Xeon includes the MSR required for UINTR.
2. So far, Intel's SDM still retains information related to UINTR.
   
   

So, where can I get all features  that supported by the CPU? Or at least I could confirm the question metioned above.

Thanks!

Hello Manoranjan,

Thank you for your reply.

We have already bought a server with Xeon 5th, and we confirmed the UINTR feature is still available.

But I can't find the document now. It's not important now, right?
