I believe I had same confusion and contacted Intel internal employee and they told me I should follow Optimization Manual and architecture day picture. https://download.intel.com/newsroom/2021/client-computing/intel-architecture-day-2021-presentation.pdf


Oh, sorry. I confused 10 and 11..
So this PR reverts 2_3_10 group introduced in 37e27a4d6509fa6432d0125bf43249d2ad01dbc3 and leaves 2_3_11 as group which is consistent with Intel Optimization manual.
