X64 is heavier and slower. Period It makes sense if you spend all your time using photoediting, video editing and alike. it makes sense if you need Hyper-V or deduplication or LXSS, which are unlikely to be used on a relatively old / low powered PC anyway. For everything else go with x86, unless you have a buggy Intel VGA you can use PAEPATCH to access 4+GB of memory, and even in that case the "wasted" memory can be efficiently used as ramdisk (say gavotte in PAE mode) to spped up browesers caches, temp folders and alike. XP 64 was an exception to that rule. Xp64 was usually faster than the x86 counterpart. But that was because it was a different (newer) product not because the x64 thing XP32 = Windows 5.1 XP64= Windows 5.2
I remember reading somewhere that you should only consider using a 64 bit OS if you have at least 3GB of system memory. Otherwise, use 32 bit.
Win7 X64 runs fine with 4GB of RAM. The Dell Inspiron 580 desktop PC that my aunt bought in spring 2011 came pre installed with an Intel core i3-550 processor with 4Gb of DDR3 RAM and Win7 home premium 64bit. that machine had four 1Gb RAM sticks as I checked inside the Dell computer case myself. 32bit/x86 Win7 should be considered when using 3Gb of RAM or less (especially with much older motherboards that can only handle the max of 2Gb of RAM).
Captain obvious said The point is not that, the point is if 32 bit runs better,and the answer is (mostly) yes. No matter i you have 2 or 25 GB of ram 32bit is faster in most of common applications. 64bit wins only in data crunching, as already stated: multimedia editing/conversion, file compression/compression and alike, very complex excel sheets and so on everithing else runs faster (or on par) in 32bit enviroments.
Any Windows 7 x64 still workable in 32bits apps and 64bits apps, the reason you had i3 core is support x64. Remember 32bits os'es are max out 3.5GB Ram, if you had installed 4gb ram, it ok.. But you won't able get full 4GB (4096MB) in 32 bits. If you use 64bits OS'es, then will more that ram showing. But my mostly apps runs x32 bits, it still workable.. Here the catch, some older apps 32 bits may not work right unless work around in x64 os'es.. just a tricky way..
That's false. Either use Paepatch or activate your win32 as hypercore and all your ram will be magically available. For the record XP Sp0 supported OUT OF THE BOX all the available RAM, then MS decided that was better to fool their customers introducing an artificial limitation.
Not really, If you enable bios has PAE to show over 4GB, on 32bits, HOWEVER, when you go to Task Manager, It will show 3.5GB! When you show SYSTEM properties, it will show 4GB+ But the Kernel 32bits will allocated 3.5GB ! 4GB total (Unstable 3.59GB) which they do it swap ram back and fourth itself.. I had patched before, still rule 32bits is MAX out 3.5GB! if PAE is on if 4GB ram is present.
