:* Input: { A0, A1, A2, A3 }, { B0, B1, B2, B3 }
:* Output: { A0 − B0, A1 + B1, A2 − B2, A3 + B3 }

====AOS ( Array Of Structures )====
;<code>HADDPD</code>
:''Horizontal-Add-Packed-Double''<ref name=":0" />
:* Input: { A0, A1 }, { B0, B1 }
:* Output: { A0 + A1, B0 + B1 }
;<code>HADDPS</code>
:''Horizontal-Add-Packed-Single''<ref name=":0" />
:* Input: { A0, A1, A2, A3 }, { B0, B1, B2, B3 }
:* Output: { A0 + A1, A2 + A3, B0 + B1, B2 + B3 }
;<code>HSUBPD</code>
:''Horizontal-Subtract-Packed-Double''<ref name=":0" />
:* Input: { A0, A1 }, { B0, B1 }
:* Output: { A0 − A1, B0 − B1 }
;<code>HSUBPS</code>
:''Horizontal-Subtract-Packed-Single''<ref name=":0" />
:* Input: { A0, A1, A2, A3 }, { B0, B1, B2, B3 }
:* Output: { A0 − A1, A2 − A3, B0 − B1, B2 − B3 }
;<code>LDDQU</code>
:As stated above, this is an alternative misaligned integer vector load.<ref name=":0" /> It can be helpful for video compression tasks.
;<code>[[MOVDDUP]]</code>, <code>MOVSHDUP</code>, <code>MOVSLDUP</code><ref name=":2" />
:These are useful for complex numbers and wave calculation like sound.
;<code>FISTTP</code>
:Like the older x87 <code>FISTP</code> instruction, but ignores the floating point control register's rounding mode settings and uses the "chop" (truncate) mode instead.<ref name=":2" /> Allows omission of the expensive loading and re-loading of the control register in languages such as C where float-to-int conversion requires truncate behaviour by standard.

===Other instructions===
;<code>MONITOR</code>, <code>MWAIT</code>
:The <code>MONITOR</code> instruction is used to specify a memory address for monitoring, while the <code>MWAIT</code> instruction puts the processor into a low-power state and waits for a write event to the monitored address.<ref name=":2" />
