Phoronix: Intel Discloses New CPU Instructions, Enhanced Hardware Feedback Interface (EHFI)

Intel updated their programming reference manual this week with some interesting new additions, primarily around user interrupts and the enhanced hardware feedback interface...

Could someone please let Intel know that the only thing that matters in computing is DP operations (HPCC)?

Could you please explain with a little more detail? I'm not sure if you're ironic or just trolling.

Whoa they added a new set security mode x86 instruction:

MOV AX, 0
BUY AMD ; Turns on secure processor mode

Mmmm, EHFI sounds like exploiter's candy.

Let's hope Intel learned something this past couple of years

I'd like a definite answer, from someone who really knows---

How many instructions are now in the x86 instruction set?

All of them.

Some time ago I read that AMD was suing Intel to ensure exclusive access to one of the three free "big blocks" of instructions that remains in the x86 architecture, in order to be able to add new instructions without risking clashing with the ones added by Intel. Does anybody know if they achieved it?
