Leopard = Faster?

I doubt most apps can/will take advantages of 64bit OS

so my answer is no

 

I didn't know the new core 2 duos were 64 bit... are you sure they are?

 

yes they are.

and defeated is correct, unless the app is able to take advantage of, and use the full 64 bits it won't make a difference.

 

PlaceofDis beat me to it!!!!

 

But Leopard will take advantage of the 64bit architecture, so in theory leopard should be much faster right? or is OSX already taking advantage of this?

 

Perhpas should be posted to a new thread ... but what exactly is the advantage of 64-bit? I know it means that it can count higher and access more memory, but otherwise, what's the benefit? Like, how could 64-bit benefit Safari, or Mail, or OmniOutliner?

 

But wasn't Leopard written in 64-bit compatible code allowing it to take advantage of this technology?

 

emmmm, good question, whats the purpose of an OS? eventually, the question is " is photoshop/vlc/office faster?"

leopard is faster or not, is not a really a problem. IMO

If you really want to know if a 64 bit OS is "faster", rather then guess, you can just search around about the OSes already in the market, see if "vista 64 is faster than vista 32"?

 

You will not notice any speed difference due to the mere change in 32bit to 64bit. Some killer apps may apply but I'm going to guess you don't use any scientific software.

crab apple are apples, you know. people mix them in the cider to enhance flavor, you know.

 

Well actually... in 64-bit mode on X86 chips the number of available registers doubles. This means that X86 processors are faster in 64-bit mode than 32bit mode. So you will notice a difference.

G5 chips on the other hand are a different kettle of fish and won't see an increase.

 

It's like having Windows on boot camp

 

64bit Leopard or Tiger will allow PSCS3 to directly address up to 8GB of RAM.
32bit Win Vista, for example, is restricted to a system total of 4GB. (32bit maximum).

Leopard will be perceivably "faster" due in part to CoreAnimation handing off more of the UI functions to the GPU.

 

Well it should allow access to a lot more than just 8GB of ram. Also x86-64 processors benefit from increased register count in 64-bit mode which allows them to run faster.

 

8GB is the limit for CS3 in a 64bit OS.
This limit is not based on the theoretical limits of 64bit software, but rather the limits of the latest Photoshop architecture.

 

I.E., bad design

 

It's probably just a compromise based on diminishing returns.
The benefits of addressing more than 8GB of memory would probably be swamped by disk access bottlenecks with files over 2GB.

CS3 is certainly a vast improvement over CS2, in terms of memory addressing.

 

I run parts of CS3 on my new 2.66 duo, and it is screaming fast compared to my old G4 Mdd duo 1.25 model. Instant squee. CS2 was just PURE JUNK.

Obviously Leopard will work faster on the 64 bit machines. That's just common sense, unless Apple really blows it and loads in code that slows it down horribly fast, but I doubt it.

 

Wider registers doesn't imply faster CPUs unless instructions previously had to be broken up into successive feeds. For what an instruction oriented computer does 64-bit is total overkill. 64-bit lets you deal with inordinate quantities of data in RAM without swapping but it doesn't at all mean "faster". If anything it will be a bit slower as more data has to be fed into the CPU(s) and a lot of that will be "empty".

 

How about more registers? You know maybe double ... like in the x86-64 instruction set...
