Graphics, User Interfaces From John Nack's blog: "In the interest of giving customers guidance as early as possible, we have some news to share on this point: in addition to offering 32-bit-native versions for Mac OS X and 32-bit Windows, just as we do today, we plan to ship the next version of Photoshop as 64-bit-native for Windows 64-bit OSes only."

Everyone is talking like the 64 bit version is going to be three times faster than the 32 bit one. For the average CS user the difference would hardly be noticeable.

People have weird expectations about 64bit apps and OSes in general. Lots of people seem to think it would atleast double the speed of their computer if they started using 64bit apps but that just is wrong. Most apps will not benefit from it at all, 64bit instructions mostly only benefit if you have to do lots of maths. In the case of CS it would likely only benefit things like filters, and even then only marginally. The GUI itself will not be any more responsive or anything than in the 32bit version, neither the generic tools available.

The good thing about 64bit CS is that it allows CS to access a lot more memory at once without the OS having to do paging. So, if you are manipulating several very high-quality images it might benefit you. Still the benefit will most likely be negligible.

I completely disagree. The effects are negligable for something like word processing. If you are doing anything even remotely professional with CS, you are going to feel the difference for anything involving encoding or other extremely CPU intensive tasks, let alone the difference the extra ram makes.

CG animation and frequent compiling, and gaming are the only areas I can think of where it would make as much of a difference.

In the general case, yes. When talking about x86 processors, not true. In 32 bit mode, an x86 processor has 8 general purpose registers to work with. That's not much, and limits the efficiency of code. When in 64 bit mode, you've got 16 registers. You get about a 20% speed increase just from that. If we were still talking PowerPC here, then yeah, 64 bit wouldn't help.

64bit instructions mostly only benefit if you have to do lots of maths. In the case of CS it would likely only benefit things like filters, and even then only marginally.

What do you think filters are, if not lots of math?

Yeah, 64 bit helps when doing math on huge numbers - which Photoshop probably doesn't do - but the bigger help is when using lots of memory, which Photoshop is known for.
