P.S. it makes sense, since AVX-128 instructions clear the upper half of a destination YMM register, so even AVX-128 touches all 256 bits of YMM reg. <small class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/109.188.120.144|109.188.120.144]] ([[User talk:109.188.120.144|talk]]) 09:22, 25 October 2015 (UTC)</small><!-- Template:Unsigned IP --> <!--Autosigned by SineBot-->
: It lacks a citation anyway, so feel free to remove it. I think it was based on the 128-bit forms doesn't use YMM registers.[[User:Carewolf|Carewolf]] ([[User talk:Carewolf|talk]]) 09:19, 26 October 2015 (UTC)
== 15. Disadvantages - Frequency drop because of using some AVX instructions ==
Using AVX2 registers in 256 bit mode and AVX512 can slow down the program because the overheating protection will drop frequency when some heavy load AVX2 and AVX-512 instructions are used. Read this [https://lemire.me/blog/2018/09/07/avx-512-when-and-how-to-use-these-new-instructions/ Article for more informations].
