ops executed.

B3H

A0H

SIMD_UOP_TYPE_EXE

C.ARITHMETIC.AR

SIMD packed arithmetic 

micro-ops retired.

This event counts the number of SIMD packed arithmetic micro-

ops retired.

C0H

00H

INST_RETIRED.ANY_P Instructions retired 

(precise event).

This event counts the number of instructions that retire 

execution. For instructions that consist of multiple micro-ops, 

this event counts the retirement of the last micro-op of the 

instruction. The counter continues counting during hardware 

interrupts, traps, and inside interrupt handlers.
