    Is my Intel Dual Core processor 64 bit ?

    Sanjeeva

      I have recently purchased a desktop with a Pentium Dual Core E5300 2.6GHz processor. When I checked this processor under Properties, under system type it indicates "32 bit operating system" . This is contrary to the Intel wesite's information which confirms this processor as 64 bit.

       

      Is my processor 32 bit or 64 bit ? How do you determine ?

          Yes you have a 64 bit CPU but you have a 32 bit OS you need a 64 bit OS.

            Thanks for your prompt answer. I have installed Windows7. How could I have a 64 bit OS as you suggest when Im already running on Wndows7 ?

              Because you can have 32 bit and 64 bit Windows 7 when you install 32 bit Windows 7 it will only be 32 bit and when you install 64 bit Windows 7 it will only be 64 bit.

                Dear Peter,

                 

                Thank you indeed for your reply.It has been very helpful.

                 

                Could you also tell me, now that I have 32bit Widows7, is it less speedier than 64bit Windows7?

                  Yes and no.

                  64-bit OS (in this case Windows 7) does not make 32-bit program run faster, however 32-bit OS can not run 64-bit programs.

                  64-bit program is also not always faster than 32-bit counter-part assuming there is one.

                  As a matter of fact, if 32-bit and 64-bit programs are doing the exactly same thing, 32-bit program will run faster.

                   

                  Having said that, 64-bit programs are generally newer, does more and designed to take advantage of 64-bit architecture has to offer thus run faster than its previous generation 32-bit programs.

                   

                  It is more apparent in CPU/memory intensive applications like (Photoshop, Encoding, and so on).

                  If programs you have are all 32-bit programs, there should not be any compelling reason to upgrade to 64-bit.

                  On the other hand, if you want to take advantage of 64-bit architecture (such as more than 4GB memory) and applications in 64-bit edition,

                  you can consider installing 64-bit OS (Windows 7) because 64-bit OS will run 32-bit programs.

                    laafe! I'm really happy to read your reply, Because I'm now unable to use some programs (After Effect CC, Adobe Premiere Pro etc.) in 32-bit (in windows 7) .

                     

                    Unfortunately I saw another discussion through this title "Is dual core a 32 bit or 64 bit architecture?"  There I found someone say something like that  "Dual-core doesn't necessarily mean that it supports 32 AND 64 bit. There were plenty of dual-core processors that were 32-bit only (the old Core Duo series for example, before Core 2 Duo). " 

                     

                    So, Could you please say something about it.

                      Intel Pentium Duo-Core E5300 is an Intel 64 processor, some later stepping also support Intel VT-x technology.

                       

                      64-bit OS (in this case Windows 7) does not make 32-bit program run faster, however 32-bit OS can not run 64-bit programs.

                       

                      Most 32-bit O/S written for x86 architecture could not run 64-bit programmes, but Mac OS X 10.5 (through 10.7) is the exception, for which 64-bit applications could be executed on 32-bit kernel. But it might be called a 32/64-bit hybrid O/S rather than 32-bit O/S.

                       

                      64-bit program is also not always faster than 32-bit counter-part assuming there is one.

                      As a matter of fact, if 32-bit and 64-bit programs are doing the exactly same thing, 32-bit program will run faster.

                       

                      64-bit O/S produces much more overheads than 32-bit O/S, so not all the applications benefit from it. Those overheads and the transitions between 64-bit and 32-bit would make 32-bit applications suffer a slightly performance degrade. But the resources provided by 64-bit architecture would enable the 64-bit programmes working even faster, even doing exactly the same thing. For the underlying 64-bit computing resources, Intel 64 processor could also boost the performance of the programmes written for IA-32 architecture through their advanced microarchitecture.

                       

                      So, for the restricted hardware configuration, 32-bit O/S might be the best choice.

                       

                      Is dual core a 32 bit or 64 bit architecture?

                       

                      Even though Dual-Core and 64-bit are completely two things, but all the desktop dual-core processors from Intel are 64-bit. But for mobile platform, early dual-core processors does not enable 64-bit computing. The very first 64-bit desktop processor from Intel is Pentium 4 3.2F release in August, 2004.

                       

                      I wish this over late reply would be found something valuable.

                        Janagewen Thanks. Yes I've found my solution, Finally. And I discovered my Dual-Core.. It is 64 bit when I was searching through It's number [Intel Pentium Duo-Core E5300 is an Intel 64 processor]
