32 bit vs 64 bit

[Eric]

I am using XP SP3 32 bit, does anyone have any suggestions on any advantage

on 64 bit system for Window 7? and which version of Office is 64 bit? Can 64

bit system run on multi-processors for better performance? My PC gets 2 Xeon

Processors, which run independently for office 2003, so I need to open Office

twice to fully utilitize CPU resources. If I open one excel, it can utilitize

only 50% of CPU resource for one processor, so I need to open one more excel

to utilitize another CPU resource. If I use 64 bit system for window and

office, can I only open Excel once and fully utilitize multi-processors'

resource?

Thanks in advance for any suggestions

"... any advantage on 64 bit system for Window 7?"

- Accept/Utilize more memory

- It's the way things are going, if you plan on having a computer over the

next few years - 64-bit is not going to hurt you in the long run - but help.



"... which version of Office is 64 bit?"

- Currently (as of this posting) - none. But they all run on 64-bit

Windows just fine.



"Can 64 bit system run on multi-processors for better performance?"

- Yes - but so can a 32-bit system.



"My PC gets 2 Xeon Processors, which run independently for office 2003, so I

need to open Office twice to fully utilitize CPU resources. If I open one

excel, it can utilitize only 50% of CPU resource for one processor"

- No, not really. Sounds like you just don't understand what you are

seeing. After all - you are just using one processor for one copy of some

Microsoft Office executable and another processor for another copy of some

Microsoft Office executable. Truly a waste and if a Microsoft Office

product ever needs multiple processors to run at top speed - it's gotten

*way* too bloated - for sure. And you probably have multiple core (probably

dual) processors as well as having two processors.



"If I use 64 bit system for window and office, can I only open Excel once

and fully utilitize multi-processors' resource?"

- Again - I really don't think you inderstand (first) just how little power

you need to run a Microsoft Office product at maximum efficiency and

(second) just how your system is allocating resources (properly.) If it is

using 50% of a single processor - it is likely using a high percentage of a

single core of a dual core processor within your multi-processor system and

the other cores and processors will be used by other processes as needed.

Office 2010 will come in both 64bit and 32bit versions, earlier versions are

32bit only.

You need to check that all your hardware / periferals support 64 bit before

you switch.

Whether there will be any performance increase might depend on how extensive

your excel books are, and then whether its a real life noticible performance

increase or simply a test environment increase

"Multithreaded Recalculation in Excel 2007"

The implication of that article, is that a modern version

of Excel can make better use of multiple cores. But the precise

details will depend a lot on what software technologies are

being used in the worksheet.
