Today, Apple released their El Capitan update to its line of Mac computers. Among other features, the company said it will add Metal to the Mac. At WWDC in California this summer, Adobe also announced that they are working closely with Apple in order to bring the highest performance upgrade possible the its Creative Cloud apps (but mostly to GPU-demanding programs).
I wanted to see whether or not having the new OS X El Capitan and the updates to the CC apps would really make a big difference in export time inside of Photoshop. To do so, I recorded how much time it takes to save two versions of three different files. For each, I will save a master and uncompressed .PSD file as well as a flattened TIFF file with ZIP compression in the ProPhoto colour space to. Of course, Photoshop hasn’t yet been updated to take full advantage of Metal and so I can only test the “before” rendering times. Now keep in mind that my MacBook isn’t powerful; it’s a 13 inches, core i5 with 8GB of RAM from last year. I have a feeling that the improvements are going to be better if a mightier machine with a proper discrete GPU is used. Anyways, here is a table of the data in question (those were tested using OS X Yosemite):
As you can see, the time it take to save the different files can vary greatly. I hope the update will reduce those numbers and the new numbers will come out as soon as possible in a part II of this blog post.
Do you have a Mac computer? Are you eager to see whether or not Apple’s and Adobe’s updates for Metal will help your cause? Let’s start a discussion below!
