In an attempt to answer that question, I used VMware Fusion 7 on a Mac Pro, created identical VM's... 512 GB RAM, 2-cores, but one with the latest i586 build and the other with x86_64.

Data below, but quick summary:
PHP test was 16% faster with x86_64, Asterisk transcoding 20-40% faster with x86_64, but openssl AES test was nearly identical (not shown).
