Raistmer:
Fine (if it can be fine at all) you just confirmed my own observations!
Same distribution here (I tried SSE-nly build too also, it works).
EDIT: no, not exactly the same. I have SSE2 not working too and it works on your CPU...
But all x64 fail here too...

No SSE2 dont work here also.

SSE3_AMD, SSE3_INTEL and SSE4.1

Here is my full bench SSE3_AMD vs SSE3_Intel.
Intel version is faster on each angle range.

That's great news!, probably means the caching & SSE3 implementation is improved enough in that model to negate the need for a special AMD build with the earlier libraries. That probably means 1 less build already, if we can manage to statically link in the libs needed by the older AMD chips :) I think the Instruction set convergence will end up making things substantially easier, so we can get back to optimisation instead of build & library juggling. Here's hoping ;)
Raistmer:
I would not talk about any convergence after these tests done. Looks like divergence much more adequate term...
Look for number of builds that DON'T run on these new AMD chips...
Whole x64 AKv8b2 set fails to even report error...
