There's no such thing as 86bit...

86 = x86 = 486-PentiumI/II/III/4..... = 32-but
64 = x64 = 64-bit
Scaling to 128-bit cpus has nothing to do with it.

p.s. You currently don't get much of a performance boost by using your computer in 64-bit mode, so most people aren't using it. 128-bit should be the same.
