I did 3 quick tests: an early 2010 iMac (ATI) - 16 bit renders considerably slower than 32 bit a late 2010 MacBook Pro (Nvidia/Intel) - the Intel GPU doesn't even support 16 bit (!!), and the nvidia performs just a tiny bit slower in 16 bit than it does in 32 bit (that said, there was enough variance that they could be tied). So of all 3 GPU families (though a very limited sampling of them to be honest), none perform better in 16 bit mode, and 1 doesn't even work at all.
