Yes, AXV2 and AVX-512 code paths have far higher performance than the
scalar paths. However, that performance comes at the cost of not supporting=
all features. What the drivers then do at initialization time, is they
check the offloads requested by the app, and then select the highest
performance code path that can support those requested offloads.
The whole process should be transparent to the user - they just get the
best performance possible for their running conditions...
