I want to know my laptop have 32 bit or 64 bit CPU not the OS type which can be seen from computer -> properties. Can it be possible to install window 7 64 bit on a 32 bit machine ?

Best answer

download cpu-z
it will be a zip file. unzip it and then run the exe and then it will collect info about your processor and then under the CPU tab, in the instructions column, see if you have any of these AMD64, x86-x64 or EM64T. if you have any of these then your processor is 64 bit.

this was the direct way. other way, right click "my computer" and then click properties and note down your processor number and then google it and then see in its specs if it is 64 bit or 32 bit. however, if your computer is any p-4 at 3 GHz or above or any new processor than that or any AMD 64 or AMD dual core then you have a 64 bit processor.

you can even see the specs of your computer at your manufacturers site to see if you have a 64bit processor.

but i think that a software's installation will be more affected by the technology of the OS if its 64bit or 32bit than from your processors technology

I always do check what PC i am using.
Easiest way to do this is
1. Check your Computer properties
2. There you will get your processor type under "System"
e.g: Intel® Core™ i3-2120 CPU @3.30Ghz
3. So your CPU is "Intel i3-2120" Processor.
4. And "Google it".

I am confused with all 32/64 bit architecture for Hardware/OS/Binary, Can someone please help in clarifying this queries?

  1. Of'course 64 bit hardware is faster than 32 bit, still there are people who prefer 32 bit over 64 bit hardware, Why so?
  2. If I have 32 bit Hardware then On that can I run 64 bit OS? (and vice versa)
  3. If I have a 64 bit Hardware and 32 bit OS then what will be the speed of my OS, as per 32 bit or as per 64 bit? (and vice versa)
  4. If I have 32 bit OS then can I run binary of 64 bit on that? (and vice versa)
  5. Is it necessary to compile binary with 32/64 bit both or we can compile with any and use it in both?
  6. Is the speed of the process also depends on type of binary that I have? For example, If I have 64 bit hardware and 64 bit OS but I have a binary which is compiled with 32 bit compiler then what will be the speed difference?

P.S. I know its basic and silly queries but lets clear now before it gets too late. :)

I want to install Python on a PC with the 64 bit version of Windows 7. I want Python to be able to use as much as possible of the RAM.

When I install the 64 bit version of Python I find that sys.maxint == 2**31 - 1 Whereas the Pythpon installed on my 64 bit linux system returns sys.maxint == 2**63 - 1.

It looks to me as though 32 and 64 bit versions of Python on 64 bit Windows are both really 32 bit Python, differing only in how they interact with Windows. So I wouldnt expect 64 bit Python running on 64 bit Windows to allow the large data struictures I could have with 64 bit Python running on 64 bit linux.

Is that true?I have spent a couple of hours searching for a definitive description of the difference between the 32 and 64 bit versions of Python for Windows and haven't found anything.
