The CPU is still perfectly capable of 32bit calculations. Even 8 bit calculations. What you can't do is use 32bit pointers (though, strictly, you can, but x86-32 isn't well supported, I wonder why?)
- y4mi 8y agoYou are technically right, but only because I expressed myself very poorly. The CPU is naturally still able to do 32 bit calculations. What you can't do is run a 32 bit application without emulation after a 64 bit system has booted. The libraries are obviously also required, but it still won't be able to start without the emulation adding 0 to the memory blocks.

- SIXTWOSIX 8y agoIt's not -entirely- true but it's not false, either as far as I'm aware. Windows in specific uses WOW64 -- Windows 32 on Windows 64. It's an emulation layer that doesn't actually hamper performance but does do things a bit differently than a native OS -- such as running all 32bit programs in 'user mode' rathe than with elevated permissions.
