What's the Point?

Im just wondering.. What's the point of using 64 bit... I understand that you are able to use more RAM(I think) but I mean, what are the other benefits from just running in 32 bit mode?

Computer: Gateway 838GM | 9.5.0 Vodoo Kernel |2.0 RC4 Chameleon Bootloader | Processor:Intel Pentium 4 630 / 3 GHz | RAM: 512MB | OS: Windows 7 32BIT, OSx86 iPC 10.5.6 | Mainboard Chipset: Intel 915G Express | Graphics Card:Integrated Intel GMA 900 | Video Memory: Dynamic Video Memory Technology 3.0 | Audio:ALC 860 |Card Reader:8 in 1 Integrated| Hard Drives:1x 200GB SATA(Win 7), 1x 320GB SATA(OS X) Both Internal

Faster performance because it uses more CPU Registers. More "Bandwidth" for ram, and many more.

so is Xbench higher in 64bit mode? I find that hard to believe...

It is actually. So is Geekbench.

You cant just judge the performance by low level benchmarks like Xbench.
In my opinion most current apps that are 32 bits only will see no benefit from running in 64 bits, I dont know if there are many other 64 bit apps nowadays apart from Apple's Finder, QuickTimeX and the such... Of course that will change in the (near) future.
Keep in mind Leopard's kernel is a PAE kernel already that can address more than 4 Gb of RAM.

As Thorazine said. Also, 64Bits means that all math operations are done almost twice as fast. If system is 64B and all apps are 64B - You will see an increase in performance using those apps. Don't measure it with benchmarks - they're very often all wrong. In Snow Leopard almost every essential system app is 64B now, including Finder, Mail, Safari, Preview, QuickTime etc. i guess only iTunes and few others are still 32B - what's actually strange cause if i remember well - there is 64B version of iTunes for Windows.

Ah, yes, everything true here, but as of right now, not the future, there is no big deal about 64bit.

The thing is, even in "32bit", SL runs many base system functions in 64bit. The "top" layer is then derived to 32 or 64, and this is due basically to coding.
So, in essence, and in broad general terms, a 32 bit app (even with "SL support") will always "cap" out it maximum performance beneath a layer of 64.
Even today's 64bit apps, you will not see a performance increase, like Safari or iTunes whatever.

Now, when big productivity suits appear, like Photoshop, Protools, 3d modeeling apps and achitecture rendering stuff... or games! damn I am waiting for theses to star showing up !! haha... anyways, yeah these guys will be able to harness the trues power of 64bit, be it in CPU math, RAM requirement and pushing bottlenecks in your system.

Add to this Grand Central, and surely you will feels a new era of home computing.
I've been running 32 and 64, for instance Fusion only runs if I boot 32bit, and the OS is so responsive anyways, I don't feel any difference at all in any app whatsoever. Click on anything and before my eyes get to screen center, its there already. Absolutely amazing. But, having this said, I dont understand WHY Apple is making almost its entire line to boot in 32bit, except servers and I think the big quads. Surely for compatibility reasons, but the way its going, in no time at all 32 bit will seem prehistoric.

Personally, I can hardly wait to be able to have 8Gb ram filled with drum samples

ive heard abouyt people being able to use 64 bit, With my specs(which are crap anyways) should I try to use 64 bit? or just be happy it works...

I'd say go for it, as long as you can get gfx working QE/Ci.

Made my machine feel like I had upgraded ram and cpu ! Its so snappy, its ridiculous. But I dont think its possible on a P4 without vooderized kernels... I really dont know... Isnt the minimum official specs at least a dual core?

Im using mostly generators rather than sample libraries, but for drums and few other categories that would be pretty cool =)
