PERFORMANCE-MONITORING EVENTS

C7H

10H

SIMD_INST_

RETIRED.VECTOR

Retired SSE2 vector 

integer instructions.

This event counts the number of SSE2 vector integer 

instructions retired.

C7H

1FH

SIMD_INST_

RETIRED.ANY

Retired Streaming 

SIMD instructions 

(precise event).

This event counts the overall number of retired SIMD 

instructions that use XMM registers. To count each type of 

SIMD instruction separately, use the following events:
• SIMD_INST_RETIRED.PACKED_SINGLE

• SIMD_INST_RETIRED.SCALAR_SINGLE

• SIMD_INST_RETIRED.PACKED_DOUBLE

• SIMD_INST_RETIRED.SCALAR_DOUBLE

• and SIMD_INST_RETIRED.VECTOR
When this event is captured with the precise event 

mechanism, the collected samples contain the address of 

the instruction that was executed immediately after the 

instruction that caused the event.

C8H

00H

HW_INT_RCV

Hardware interrupts 

received.

This event counts the number of hardware interrupts 

received by the processor.

C9H

00H

ITLB_MISS_

RETIRED

Retired instructions 

that missed the ITLB.

This event counts the number of retired instructions that 

missed the ITLB when they were fetched.

CAH

01H

SIMD_COMP_

INST_RETIRED.

PACKED_SINGLE

Retired computational 

SSE packed-single 

instructions.

This event counts the number of computational SSE packed-

single instructions retired. Computational instructions 

perform arithmetic computations (for example: add, multiply 

and divide).
Instructions that perform load and store operations or 

logical operations, like XOR, OR, and AND are not counted by 

this event.

CAH

02H

SIMD_COMP_

INST_RETIRED.

SCALAR_SINGLE

Retired computational 

SSE scalar-single 

instructions.

This event counts the number of computational SSE scalar-

single instructions retired. Computational instructions 

perform arithmetic computations (for example: add, multiply 

and divide). 
Instructions that perform load and store operations or 

logical operations, like XOR, OR, and AND are not counted by 

this event.

CAH

04H

SIMD_COMP_

INST_RETIRED.

PACKED_DOUBLE

Retired computational 

SSE2 packed-double 

instructions.

This event counts the number of computational SSE2 

packed-double instructions retired. Computational 

instructions perform arithmetic computations (for example: 

add, multiply and divide). 
Instructions that perform load and store operations or 

logical operations, like XOR, OR, and AND are not counted by 

this event.

CAH

08H

SIMD_COMP_INST_RETIRE

D.SCALAR_DOUBLE

Retired computational 

SSE2 scalar-double 

instructions.

This event counts the number of computational SSE2 scalar-

double instructions retired. Computational instructions 

perform arithmetic computations (for example: add, multiply 

and divide). 
Instructions that perform load and store operations or 

logical operations, like XOR, OR, and AND are not counted by 

this event.
