Adobe CS2 running on Intel machines - Rosetta?

I've heard that the Adobe CS2 software does not run natively on the Intel mac platform.
Is this correct? Where I work we have currently purchased the CS2 licence but at the moment only have 1 machine running on the Intel platform running the CS software, but could be upgrading any G4's we have with G5's and as all new Apple macs are now running on the Intel platform this could be an issue.
Now I've heard about Rosetta but could somebody explain a bit more about this please.
And I've also heard that CS2 running in Rosetta on an Intel G5 would be no faster than a G4 with a load more Ram installed.

As you can tell from the above speal, I have heard alot :D but have no real concreate information, hence me asking the questions.

Any help with information would be great.

you say Intel G5, but that's a contradiction in terms, the G5 was the PowerPC predecessor of the Intel Core chips. iMacs dow ship with Intel Core 2 Duo's inside them.

Rosetta, yes, is the technology that emulates the G3/G4/G5 architecture (PowerPC) on the fly, and in the background, an invisible layer.
Traditionally, Emulation has been rubbish, did you ever use Virtual PC? that emulated a windows environment on PPC macs, and the speed differences was excruciating, the best it could do was emulate a Pentium II 400mhz, i believe...

Rosetta manages to be 'fast enough', with users noticing slightly longer load times, and lots of ram usage, but other than that, a smootth operation.

here's one review, from a user on here:

Apologies, yes I see what you mean i.e. G5=PowerPC, Mac Pro=Intel
I didn't realize they were re-branding the machines from G5 to Mac Pro's :eek:

I haven't used Virtual PC before but to be honest I probably wouldn't anyway.
I'll do a bit more digging me thinks :)

But thanks for the info. I will checkout the link.

I run adobe CS2 on my mac pro... and run photoshop cs1 on my mac book...both intel

cant see any difference. I ran the photoshop cs1 on my old G3... no difference in the performance.
 
I have to say I definetly notice a slow-down. Coming from a 933 G4 1 Gig RAM with PS7, to a Core2 Dou iMac 2.16 1 Gig RAM with CS2. I have noticed it takes forever to swap over to Photoshop when I have anything in my paste-board. Looking at the benchmarks, my CS2 seems to run slower. But I did get a huge improvement on file searches. My old G4 would choke as I type in a word to searach - trying to search on part of the word as I type it. Now it flies.
 
Adobe CS 3 is on its way. There's rumours about a public beta for users of CS 2 to be unleashed before year's end, and the release should be in a March/April 2007 timeframe.
 
Mac Pros should give you respectable performance - more in line with a G5 than a G4. Keep in mind that ALL the Mac Pros have four cores, while only the last high-end G5 had four cores. Mac Pros will perform a LOT better than iMacs or other systems, which only have two cores.

One thing to consider is that Rosetta requires a lot of RAM. If you're using PPC apps on an Intel machine, you'll want more RAM than you'd need running those same apps on a PPC machine. 1GB was pretty comfy on PPC machines, but I recommend 2 on Intels. I think that explains Rastermon's negative experience. The benchmarks Viro posted were based on machines with more RAM than Photoshop could even use, and the results were very good.
 
Checking my processes, I see photoshop is listing 1.5 Gb as a virtual size, and I don't have anything open in it now. Would that be a symptom of my performance? Keeping in mind I only have 1 Gig RAM (didn't expect to ever say that)
