How did That happen? Core 2 is x86_64 by default...
Says who? What "default?"
Well, Randall, since your past responses suggest you are a big wikipedia fan, check here:
Wikipedia is a good thing, yes.
Its a 65bit processor. It will emulate 32bit.
65? The question was not about what it can do, but what it's "default" is.
You incur some penalty in installation size (disk space) but since the bulk of an os is moving stuff around in memory you will gain the use of 64bit registers to do this if you install the 64bit kernel.
Think more about this. The primary bottleneck in modern desktop-style computers is the memory interface. The limiting factor there derives from the cycle time of the RAM and the width of the transfer bus. Using a 64 bit processor does not change those parameters. However, it does mean that all addresses and single-word values are 64-bits wide, and transferring that any number of such 64 bit quantities is going to take twice as long as transferring the same number of 32-bit quantities. If all you're doing is a lot of string copies, you won't find much difference. But if you're doing integer arithmetic in programs written in C or C++ and those programs are compiled for the 64-bit ISA, then you're going to be moving a whole lot of high-order zero bits around. If you don't need a 64-bit architecture, you definitely should not use one. I don't need one.
