How can I know that my processor is 32-bit or 64-bit?

    Question

  • I want to know if my processor is 32-bit or 64-bit. I went to system info by typing: msinfo32 in the run commands, and there is nothing says that the processor is 32 or 64-bit. There is something says: x86-based PC , what does that mean? and how can I know that my processor is 32-bit or 64-bit?

  • Assemkh -

    Technically ALL Intel chips are x86 based - even the 64 bit ones. So I can see your confusion. One easy way would be to grab CPU-Z. On the first tab, look for the instructions section. In it, it should say something like x86-64 or IA64 if it's a 64 bit chip.

  • control panel > all control panel items > performance information and tools > view and print detailed performance and system information

    and under 'system' there will be a line "64-bit capable" where it will say yes or no.

  • Use Securable or CPU-Z.

    They are both excellent freeware utilities.

  • System info (as well as msinfo) will only say what OS bit-level you have installed; it won't say what you can install
    (in other words, it won't say your hardware architecture.)
    Most all PCs built & sold in the last few years are 64-bit capable (read:  the CPU supports a 64-bit OS.)  What processor (as listed in msinfo) do you have?  Better:  what make/model of PC?
    For some systems, there's not much point in running a 64-bit OS, as they're physically incapable of having >4GB RAM installed (the main reason for running x64.)

  • Try securable.exe, by Steve Gibson:  http://www.grc.com/SecurityNow.htm.  Look under Freeware.

    It will even show if your system is capable of Hyper-V.

    What Chris said is on the money - MOST CPUs sold in the last say, 3 years are 64 bit capable. Unless your system is one of those "small laptops formerly known as netbooks" with an older Atom processor or a Via chip, odds are quite excellent it's 64 bit.

    All AMD Athlon 64 chips - obviously - are 64 bit capable.
    Most Pentium D, most Intel Core Solo/Duo and all Core 2 * are 64 bit. Their i3, i5 and i7 chips are likewise 64 bit.

  • I have this:
    System Manufacturer: INTEL
    System Model: D865GBF
    System Type: x86-based PC
    Processor: Intel Pentium 4 CPU 3.00GHz 2992MHz 1 Core 2 Logical Processors

    But how will you know if it is 32-bit or 64-bit?
    does x86-based PC means that the processor is 32-bit?

  • Try CPU-Z (free). Look under "instructions". If it says "x86-64" there, then your CPU is 64-bit capable (older models had "AMD64" or "EMT64").

  • Sanmartin -

    If it's an Intel chip - wouldn't that say "IA64" instead? I believe that would be what they call it.

  • That's right, too. If it's a x86 compatible 64-bit chip, the instructions should read "Intel64".

  • egads -

    Ah yes... The Itanic.. That was a complete and total disaster.

    Tho I do believe the x86 came about not so much from Cyrix but the fact that all of intel's CPUs ended in 86 - as in 8086, 80286, 80386, 80486... The "x" in x86 generally means any processor from that particular family - fill in the blank for whichever model you want.

    But you're right - they couldn't lay a trademark on that naming strategy so they went with something they could. In fact, I think AMD and their clones were more responsible for the Pentium branding strategy than Cyrix... After all, AMD was also calling their chips 286, 386 and 486. After AMD lost to Intel, Intel renamed their chip family Pentium and AMD started refering to their Pentium or "586" compatible chip the
    K5. The rest, as they say, is history...

    you're right.

    Actually, your original post was correct. My bad.

    Is there a run command that I can type in Run from the start menu?

    The nice thing about CPU-Z - it's completely portable. You can stick it on a flash drive and run it directly on Win 2000, XP, Vista and Win 7.

    It's 32-bit. But why do you want to know?
