64 bit why?
-
06 Nov 2008Ok guys, I think im being lazy here but I just havent figured out the benefits of 64bit.
Can somebody with the know please fill me in on how it is better than regular 32bit processors.
I have a dual core 64bit amd processor at home, but have completely disregarded the fact its 64bit
and use it just as a normal processor.
What would be the purpose of upgrading to a 64bit os, and is it worth it? How does it affect programs
and do most programs support it. Does it need a certain directX for graphics e.t.c?
How is it better? What does it do to make it better? e.t.c

06 Nov 2008Has to do with the speed at which memory can be accessed, or the size of the memory bank that can be accessed afaik.
I have the same computer as you....64-bit proc with 32-bit windows installed since some of my hardware drivers dont support 64-bit. I'm upgrading to a 64-bit quad that'll be arriving in a few days though...and I'll have a 64-bit OS installed on it...so I guess I'll see if there's a big difference. -
06 Nov 2008On 64 bit OS you have infinite amount of virtual memory.

06 Nov 2008im talking about xp since vista is slow in every ways.32 or 64 doesnt matter.
first of all you can use 4gig or more ram. (which is very important if you run mudbox zbrush...ect.)
the cpu has more bandwith and can do more calculations per cycle.
not every program is 64 bit but 32 bit software runs with no problems on 64 bit hardware. (with 64 bit OS)
In most cases even a little bit faster then on a 32 bit system.
And a practical story. That i encountered.
As i was rendering my senior project i rendered at home on my pc a quad core from intel the q6600 which has a very good price/performance value.
After i moved to the labs of my univercity i used the 32 bit version because they were preinstalled.
I couldnt get 1 single frame out of the machines (which were macs with 4 core xeon processors on it) not even a half frame because it always crashed and said it hat no memory for the g buffer, or smt similar i cant 100% recall now.
I tryed everything i could but nothing helped. until i installed the 64 bit versions on top and used them to render and it was a success. They rendered 73 hours straight without crashing once.
(and yeah the macs had windows on them so max users could render their stuff (ok i helped a bit
) -
07 Nov 2008Sweet getting a better understanding of it, cheers.
Can anyone foresee any trouble loading up a copy of 64bitxp side by side my 32bit xp? and testing the difference that way? -
12 Nov 2008pfah! All this talk of newfangled bits and bobs - gigaflops all hanging loose! Not like in my day, I'd get at least 8 cubits per cycle from my analytical engine.

Jonathan 480 posts27 Nov 2008A 64-bit OS can access, IIRC, at least 128gb of RAM, if not more. 32-bit XP and Vista can access about "3.4"ish GB of RAM, depending on how much vRAM your GPU has (so, if you havea GPU with 1gb of VRAM, you'll only be able to access about 3gb of system RAM or less).
My main computer is 64-bit OS with 8gb of RAM, and it does quite well. However, there are some issues you'll have to get used to, mainly dealing with certain plugins, browser issues, drivers, etc. but they're not that big of an issue.
-
27 Nov 2008jonathan, how certain are you of that RAM issue? are you saying there's no reason to have more than 3gb of ram on a 32-bit OS? if so, then I'm def. getting 64-bit next time I upgrade.
-
27 Nov 2008Yeah im pretty sure the ram issue is the main reason most people upgrade. Though I think sp3 overcome's the ram issue when it comes out?
-
27 Nov 2008sp3 is out already.
and no it cant overcome the ram issue its tied to the 32 bit cpu architecture and the os.
If you use your cpu in 32 bit mode (with a 32 bit os) you cannot use more ram than 3.4gig (yeah you can do virtual memory expantion but it slows your pc down)
the best thing is to switch to XP64 (no vista since it CRUSHES your performance) -
28 Nov 2008ok so next time I upgrade I'll be sure to do xp64.
-
Jonathan 480 posts28 Nov 2008Most CPUs today are 64-bit compliant, and yeah, you can't overcome the 32-bit limitation, it just increases to 64, 128, 256, etc.
Remember the day when we referred to consoles as "16-bit," "32-bit," "64-bit," etc?
And to clarify, a 32-bit OS at maximum can only access 4gb of RAM, but that is not only system RAM. On one computer I work on, Max or other programs crash when I hit about 3.33gb of RAM usage, as the GPU is using about 512, etc. -
28 Nov 2008So thats why my max crashes!
Hooray, a solution. -
