Test results for Knights Landing
Author:  Date: 2016-12-28 02:44
I'm confused by your statement:
"AMD processors and later Intel processors (Skylake and Knights Landing) do not have such a state switch. They have no need for the VZEROUPPER"

From this discussion

stackoverflow.com/questions/41303780/why-is-this-sse-code-6-times-slower-without-vzeroupper-on-skylake

it appears that VZEROUPPER is even more important in some situations with Skylake then e.g. with Haswell.
