Photoshop CS5 64-bit benchmarks

Running Photoshop in 64-bit mode produces some big improvements when using large data sets (scenarios where you’d otherwise run out of RAM and have to hit virtual memory). Here are benchmarks from a 2 x 2.66GHz quad-core Nehalem Mac Pro with 12GB of RAM (OS X 10.6.3):

Running the Retouch Artists Speed Test:

CS4: 36.09 secs

CS5 64bit: 14.78 secs

2.4 times faster*

Running the diglloyd benchmark Actions for Photoshop:

diglloydSpeed1

CS4: 38.05 secs

CS5: 23.1 secs

1.7 times faster

diglloydSmall

CS4: 56.01 secs

CS5: 26.48 secs

2.1 times faster

diglloydMedium

CS4: 120.15 secs

CS5: 83.85 secs

1.4 times faster

Opening a large (3.75GB) PSB file

CS4: 80.33 secs

CS5: 52.43 secs

1.5 times faster

Obviously these are big, big wins for any Photoshop users working with large images. I do however want to be careful not to oversell the benefits of 64-bit. As I’ve said from the start, 64-bit is a really big deal when you’re using large amounts of memory. Otherwise it’s not likely to make a very noticeable difference (e.g. your Web design tasks won’t run twice as fast).

What about other Creative Suite apps? As I’ve mentioned, After Effects & Premiere Pro are both 64-bit native on both Mac & Windows (64-bit only, in fact, unlike Photoshop). I haven’t seen benchmarks yet, but given the data-intensive nature of video, the wins should be huge. Meanwhile Illustrator has raised the limits on RAM usage, from 2GB in CS4 to 3-4GB (depending on system configuration) in CS5.

* I’m using the same “times faster” nomenclature that Apple uses when talking about 64-bit performance on Snow Leopard. If you prefer to think in percentages, the operations are (from top to bottom above) 59%, 39%, 53%, 30%, 35% faster than CS4, respectively.

onOne posts CS5, 64-bit compatibility notes

Mike Wong from plug-in developer onOne has posted some details about their Photoshop compatibility roadmap. He writes:

Windows versions of our plug-ins have been 64-bit now for months… We are converting our plug-ins over to be 64-bit compatible on the Mac OS X side… Our goal is to have Photoshop CS5 compatible updates for the current versions of our plug-ins available within 30 days of Photoshop CS5 being made widely available…. That means we should have everything out there for you to download by June 12, 2010.

More generally, 32-bit Mac plug-ins should run just fine in Photoshop CS5, provided you choose the “Open in 32-bit mode” option in Get Info. That’s analogous to the situation on Windows, where you can run your older plug-ins in the 32-bit version of the app. (On Mac Photoshop is a single 32/64-bit binary, whereas on Windows it’s two discreet apps.)
I’ll post news about other developers’ 64-bit migration plans as I get it, and I look forward to sharing some great Mac 64-bit benchmarks soon.

Sigma announces compatibility with Lens Correction in CS5

The Photoshop team has had a great relationship with lens maker Sigma, and they’ve issued a short press release:

The Sigma Corporation is pleased to announce that, through collaboration with Adobe Systems Incorporated, Sigma lenses will be compatible with the Lens Correction feature of the professional digital imaging standard, Adobe Photoshop CS5…

Photoshop CS5 has applied the aberration information of the current Sigma lens lineup. When the improved Lens Correction filter is selected, it will provide accurate correction of aberrations automatically in accordance with each lens parameter.

We look forward to sharing more details about how lens correction works in CS5, how you can create and share your own lens/camera profiles, and even how you can use some as-yet-unannounced goodness. [Via Bryan O’Neil Hughes]
