The comparison is achievable from 2014 link and links under it in
the left frame.
The ball-park number you have probably won't change much.
Unfortunately, that is the configuration I can use on my system because
of lack of libraries for other configurations.
Using --with-fpu={neon / neon-vfpv4} shouldn't cause you ABI issues with
libraries for any other configurations.
I wonder how much of that is due to auto-vectorization (on LLVM, -O2+
turns it on, I suppose GCC is only on -O3?). From Ramana's point,
there may be nothing serious if you haven't enabled NEON, though.
Auto-vec is turned off when you have -mfpu=vfpv3-d16 . That implies No Neon.
