It's X86-64... Sony confirmed that.

Just to clarify a few things here:

The Jaguar has a 40bit addressing space, not a 64bit space, so you could clip about half a terabyte of ram onto any Jaguar chip (that is quite a lot more than 8G)

The 64bit is the "data size", simplified the cpu can process 64bit variables "in one swing".
