Adobe Photoshop CS4 Will Be 64-Bit For Windows Only

Posted by kdawson on from the takes-time-to-make-a-cup-of-cocoa dept.

HighWizard notes that Adobe Systems has shared the first scrap of information about its next version of Photoshop, CS4, and it's a doozy: there will be a 64-bit version of the photo-editing software, but only for Windows Vista and not for Mac OS X. Ars explains the history of how this conundrum came to pass — blame Apple and/or Adobe as you will.

    Well, it will run faster if you have a large pool of physical memory and do some heavy Photoshop editing, because Photoshop will be able to access more than 3GB of memory (remember that 1GB of the 4GB address space is already reserved for system code sharing) and not resort to it's own swap/disk cache system as much.

  2. But AMD64 could be... by mrchaotica · · Score: 5, Informative

    Remember, going to 64-bit on x86 can make programs faster, but not because of the extra bits. The speedup comes from the fact that, in addition to increasing the bits, AMD also added a bunch of extra registers to the spec.

    As a matter of fact, Slashdot once again misleads with the choice of headline and half-the-story lead-in. Just a bit of reading reveals:

    On the other hand, we work very hard at maintaining parity across platforms, and it's a drag that the Mac x64 revision will take longer to deliver. We will get there, but not in CS4. (Our goal is to ship a 64-bit Mac version with Photoshop CS5, but we'll be better able to assess that goal as we get farther along in the development process.) Hmmm. Not the end of the world after all.

    You're thinking of Tiger, I think. Leopard is fully 64-bit. http://www.apple.com/macosx/technology/64bit.html

    You misread the summary (so did I, at first). It's not "Adobe Photoshop CS4 Will Be For 64-Bit Windows Only," it's "Adobe Photoshop CS4 Will Be 64-Bit For Windows Only."

  6. Re:The blame falls solely on Apple by Teese · · Score: 5, Informative

    Apple have never promised 64-bit Carbon. They did promise 64bit carbon, during the 2006 WWDC. It wasn't until the 2007 WWDC that they rescinded the promise. Before the 2007 WWDC, they backed up the promise with seeds with 64bit carbon support in. They removed that 64bit carbon support in the 2007 WWDC seed. Of course they also slightly redefined what carbon meant. It now means the GUI portions of what used to be called carbon. So there are parts of "carbon" that are 64bit. They just aren't called carbon anymore.

    Just want to correct one thing: Aperture is not a replacement for photoshop it is a competitor of Adobe Lightroom. Apple doesn't have a direct replacement for photoshop.

    Yep, Adobe was told that Cocoa was the future for OS X development. And yet, they chose to stick with Carbon. Can't blame Apple for that one. Simple fact is Photoshop is designed for Windows first and then ported. So its not a native Mac app and doesn't take advantage of all the technology in OS X. If you want to see what I'm talking about, take a look at Pixelmator. While its not on par with Photoshop, it combines the power of ImageMagick with the underlying technology from OS X.
