<p>SSE3最值得一提的新功效特點，是水平式的暫存器整數運算，而在此之前的<a href="/wiki/SSE" title="SSE">SSE</a>、<a href="/wiki/SSE2" title="SSE2">SSE2</a>則僅能垂直運算。更進一步的特點是，指令執行時對多筆數值的同時加法運算、減法運算等，之後將結果進行儲存等，都可以在單一個暫存器完成，因此SSE3可以用更簡單的方式來實現同時間的多筆、大量<a href="/wiki/%E6%95%B0%E5%AD%97%E4%BF%A1%E5%8F%B7%E5%A4%84%E7%90%86"

</p><p>此外，有個新指令可將浮點數數值轉換成整數數值，且進行此種轉換不需要將運算切換到rounding模式，過去此類轉換必須先切換至rounding模式，完成轉換後再退出rounding模式，此新指令可省去此模式切換程式，使整體運算更為加速，也因此可避免鄰近<a

00000001。而所謂chop模式是即便溢位也不歸零，而持續維持在最高數值，此也稱為飽和運算，即是不讓其溢位歸零情事發生，同樣的例子，在chop模式下依舊會維持255，即是11111111 + 00000010 = 11111111。當然，截切、飽和忽略了更多的累加值，這在多媒體運算時有其需要，當音調254階再增個2階、3階，若因為溢位歸零而成為0階、1階，就會與255階相去甚遠，相對的254階若因飽和運算的效果最多會維持在255階，255階與254階仍是相近，多媒體運算力求快速即時而不力求精確，因此些許的運算數字結果偏差仍可接受。</span> </li> </ol> <div
