Tech myth - A 64-bit Operating System is faster

Have you heard that having the 64-bit version of an operating system (OS) installed on your computer will make it run faster than the 32-bit version would allow it to?

Well, this is NOT TRUE, not in and of itself - other things have to be taken into consideration especially whether or not you have a 64-bit CPU.

You see although the 64-bit version of an OS will allow for better usage of a multi-core processor/CPU, unless you give it additional memory (RAM) and use 64-bit programs you may end up actually seeing a decrease in overall performance speed.

One of the main advantages of a 64-bit OS is that it allows you to have and use more RAM on your computer.  And even then, if the programs you're using are not designed to make the most of the 64-bit OS and 64-bit CPU then you may not see any benefits worth talking about especially since the 64-bit version of an OS will use up more of your hard drive space.

NB:  A computer that comes with a 64-bit OS installed and 2GB of RAM would have been better of with the 32-bit version unless you add more RAM.

  1. Ha Ha Ha funniest article..... One would assume that when persons are referring to a 64bit os... they take into consideration that they will be using hardware and software to match ... duhh and 64bit runs much faster. Who the heck can/will install a 64bit os on 32 bit hardware anyways??

    1. There is no way you'd be able to load a 64-bit OS without having a compatible 64-bit CPU. The thing is though, quite a few persons would go ahead and install the 64-bit OS on systems that might have at most 2GB of RAM - if you're going to load a 64-bit OS then you should have no less than 3GB RAM i.e if you want to see any sort of performance improvement over having the 32-bit version installed instead.
