    Agreed: the 64-bit pointers take twice the amount of memory, and there's a corresponding overhead with (other) operands.

    Believe it or not, sometimes I miss programming for MS-DOS and putting in a small effort to make sure the program won't do nasty things on a machine that's configured slightly differently to mine.

    32 bit systems have a sell by date.

    http://en.wikipedia.org/wiki/Year_2038_problem

    In year 2038 all 32bit will be useless, so i guess that starting to replace everything a while before is a good idea, but 27 years early??

    Adding more and more extensions to the already very old and bloated x86 architecture isn't going to help. Getting away from the Outdated `IBM PC compatible' hardware would be a massive step in the right direction, it still uses a 16 bit BIOS for goodness sake.

    Also to piggy back on th is. If we was to jump into the 128bit bandwagon, we can always include existing 64bit library files for a compatibility layer (I.e; for Flash Plugin) until 128bit versions are released.

    yeah x86 has been around for a very long time... but I guess it's a big step to come up with a new arch and mass market it without some kind of retro-compat (hey look at the windows-to-linux example..)

    it would be an important step though. As for 128-bit... why do we need 1gaziolionM of ram? I have 3Gb and I never use more than 800mb (and that's when I watch HD movies or play nexuiz)

    you actualy use a lot more for the OS not just your base programs. Just type "free" on the CL. But yea I agree 3 or 4GB is enough at the moment tho.

    The first anyone has heard of 128-bit x86 CPUs was a week ago when Microsoft started saying something about making Windows 8 for "IA-128".

    I'm sure we would have heard about AMD and Intel's plans in this area earlier, if there were actually any plans afoot.

    If 128-bit x86 CPUs (or non-x86-compatible, considering that IA-64 is not x86-compatible) come out, Windows will not be the first operating system to support them. I'm sure NetBSD or Linux will support it earlier. And all our software is only a recompile away from being 128-bit compatible too!
    I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.

    Plus, many game systems (like the Playstation 3) advertise that they use 128 bit systems, where in reality, they use 64-bit processors to work with 128-bit integers, which is a different system entirely. I wouldn't be surprised if this practice continues. For the 2038 problem, yes, that definitely makes a difference in the length of support for 32-bit systems, but even if it becomes a problem by 2018, that seems like a reasonable date to lose support for 32-bit systems. 9 years ago, 16-bit systems were still relatively common (at least my family had one at home that was becoming deprecated rapidly).

    Isn't... the PS3 PowerPC arch though?
