in this time what office to use 32 o 64 bits

Hi i have now my new office 2016 jeje, i want to know what architecture use i have 8 gb ram and integrated graphic card in a pentium 3520 hope your sugestions. Really 32 bit have high compatibility? 64 bits have more perfomance?

I looked into this recently and concluded the 32 bit version is best unless you are processing extremely large Word/Excel files.

64 bit operating systems and applications were never about improved performance, although that is often an indirect result.

The primary reason why 64 bit operating systems were developed was a larger private virtual address space. Modern operating systems provide an address space (what applications see as memory) that is much larger than and quite independent of actual RAM size. With 32 bit operating systems each process has an address space of 2 GB. Understand that each process has their own private address space that is not shared with others. This is totally independent of how much RAM you have. For many applications this 2 GB address space is very confining and developers had to create some very imaginative way of coping. But this could only go so far.

In early 64 bit systems this address space was increased to 8 TB, 4096 times larger. Starting with Windows 8.1 this was further increased to 128 TB, 65536 times larger than the 2 GB of a 32 bit OS. This provides huge benefits to applications working with large amounts of data. Some things that were previously very difficult if not impossible become simple. Application developers could work with data in ways that were convenient for the application instead of trying to cram everything into 2 GB. This often improves performance.

But not all all applications will benefit. Applications with modest data requirements will often see little or no benefits. And 64 bit applications usually consume more disk space and require more RAM to operate efficiently. For technical reasons a 64 bit application can in some cases be slower than a 32 bit version.

In some cases a 32 bit application is preferred over a 64 bit version. Some applications, such as browsers and Microsoft Office, have numerous third party extensions that are 32 bit only. With a 64 bit applications these can not be used. For compatibility reasons I believe Microsoft is still recommending a 32 bit version of Microsoft Office unless you have requirements that can only be met with a 64 bit version. This situation is changing but the issues remain.

Thanks guys really apreciate your comments, now i am trying whith 64 bits, really does not apreciate diference. I see office 2010 are more quick than 2016 and the spellchecker are the same. I only see 2016 have better grammar check. But in perfomance cuestion for me 32 and 64 are same
