Windows 7: Performance: Win7 32-bit vs 64-bit

If you activate 64bit and later decide to run 32bit you can do that.

As long as you don't have software, or drivers that don't work under 64-bit there really isn't a great reason to not use it. For example, my company didn't have a 32-bit VPN client for the longest time. if you were running Windows 7 64-bit, you couldn't VPN in. That was a bit of a problem for remote workers and forced them to run 32-bit.

Agreed with the others that at 4GB of RAM, you won't notice much of a difference at all. The CPU does have access to double the registers though (32 bit can only use the first 32 registers, 64bit allows use of all 64 registers), and as such memory or CPU-bound applications do have a perceptible difference. Most apps aren't these, though, so unless you've got a reason to move to 64bit there may be little need to wipe a working 32bit OS. However, the converse is also true - there's really no reason not to use 64bit either at this point, unless you have some rather odd needs (native 16bit support, 32bit-only device drivers or 32bit software that relies on said device drivers, like VPN software). That choice is up to you, but your initial question of whether or not you'd notice a difference is pretty much moot. Windows will boot and run slightly faster, but in real-world perceptible terms, not much will change.

Thank again for all the feedback, folks.

I've run into two problems migrating to Win7 64-bit, both being programs I have used for a long time and have come to rely upon. One is an inconvience and has a simple workaround that I have been using. The other, though, is a dvd-importing app that came with my Sony Handycam -- and despite several exchanges with Sony support (during which ALL they keep telling me to do is reinstall it -- again!), still does not work.

Given the lack of performance gain, the fact that I don't have or use any of the high-end commercial apps that come in 64-bit versions, and the problem I can't fix, I'll just go back to using 32-bit.

I would bet the import program is using a driver that either doesn't work at all in 64bit, or works poorly. Those are the types of programs I would be wary of when migrating to 64bit anyway .

1. 16bit applications do not run in Windows7 - 32 or 64bit
2. with 4GBs of RAM the performance difference of 32 vs 64bit is very marginal and not noticeable
3. I have a couple of applications that do not run on 64bit - but those are rare cases
4. Yes, Superfetch will use all the RAM available for caching

You will have a lot of problems when you try to upgrade form 32bit to 128bit which is the next step. But, saying that it won't be for a good while...We hope.Otherwise we will all have to cough up large amounts of dosh for upgrading again...

Upgrading from 32-bit to 128-bit?? That's not going to happen before Windows 8 -- and by then, I'm hoping that the vendors of the two apps giving me problems will have solved them for 64-bit. And, if that OS is anything like Windows 7, it will have a way of running "old" 64-bit apps.

Win8 won't even be 128-bit

Differences between 32 bit and 64bit. 32 bit recognizes only 4 gigs of 1033 mhz may show you your memory stats but only shows what the system requirs of. So if you have above four gigs of stick and running frequency of 1600mhz. 32 bit will not recognize thats of memory yoy had put in. 64bit on the other recognizes 24 gigs of memories. You can tell the defferenceon the speed of Booting up the system. A bit faster than 32. Some say they care less some do.or some dont know but pretends to know so they say i rather stick with 32 ... it all depends on you and your system if you want all ypur hardware to be recognize what it actually is not just. An os requirements. Hope this answers your questions and others as well. Any questions ask away. Thanks.

IMHO, 32-bit W7 seems "snappier" on older machines that I've upgraded to Win7. See my post elsewhere in the forums.
