Windows 32bit vs 64bit

post #1 of 21
Thread Starter 
I'm sure this has been done to death, but I need more...

I'm currently running 32bit on a 2.4 i5 450m 4gb RAM and 335m 1gb...

My main concern is will Windows generally be snappier... And is it a noticeable?

I also do some gaming, but not a ton. I don't do any encryption SSL stuff, but do occasionally re-encode .avi's to .3gp etc...

I've googled benchmarks but it comes up with virtually nothing... Just some discussions and some stuff from Vista back in 2006... Anyone have some benchmark links or can comment...?

I would run 64-bit for the extra memory usage.
For example, when I open the Dubstep fanatic thread, with 100 posts per page, and 3-4 videos per post, firefox/chrome both stall with 4GB.
In Waterfox (64-bit Firefox), it's smooth and fine.
it might be different coding, but I can say that using programs in 64-bit is much more versatile.

if you have a 64bit cpu i suggest using a 64bit OS. with 64bit you can also use all of your ram. I think 32bit only alows 3.5 iirc

Yeah your system will run better.

It allows 4GB, except for Windows 7 starter which allows 2GB.

now i have 4gb, it looks like 2.7gb available... i'm assuming this is overhead and my integrated using 1gb of address space... will that change if i use windows 64? or will it still be 2.7 avail...?

also confused there's no benchmarks available on the net...

Windows is ultra-conservative when it comes to using your RAM (doesn't scale like I, and others surely wish it did) so when it comes to basic Windows features it won't use too much more RAM but it will be slightly less stingy when it comes to allocating more memory to programs.

 

It's also the type of thing you won't notice immediately without heavy intervention so don't let a temporary install sway you too much. With the RT7Lite version of Windows 7 x64 I put on my mom's computer it used around 700mb of RAM at boot whereas now it uses around 900mb at boot(She has 6gb total for reference, 2x1gb/1x1gb per channel). All she does is light office work and play Cityville so there is next to no difference between when it was first installed and now(besides it using more RAM now).

 

Oh, and most importantly - It has definitely made Waterfox and MS Office load more quickly and run more smoothly

what i mean is the actual physical ram available is 2.7gb TOTAL with 32bit.... the missing 1.3 i'm assuming is a GB to integrated GPU address space and the rest being overhead.... if upping to 64 bit, will the amount of available change...?

The total is because Windows 32-bit's have always been limited to less RAM.
Mind posting a snapshot of Task Manager -> Performance?

friend says he doesn't care what any one says, that he can tell x64 is snappier in some places. I think it may actually be true to extend i bet 32 bit is optimized for older hardware to an extent. in general old hardware and new hardware are optimized to run certain things a certain way ie new gfx card blows chuncks on 3d mark 01 but, old gfx card creams new gfx card at 3d mark 01.
