A pretty good start for Adobe:Īnd the good news spread with every test we did. In the import test, the ARM-optimized version was about 13.5 percent faster than the Rosetta 2 emulation for both Sony and PhaseOne files and 20 to 24 percent faster than the Intel version, which runs on an Intel chip. The results are presented as the average of at least three consecutive runs to compensate for inconsistencies, although we did not see any major change from run to run in any of our tests. By switching to 1: 1 previews, we can ignore changes to the screen resolution / default preview size, and since 1: 1 previews take longer to generate, they provide us with a better basis for comparison. Note that these tests are a little different from previous benchmarks we ran using standard previews when importing. The imports were configured with 1: 1 previews, all other check boxes were deactivated, and the exports were carried out in two variants: sRGB-JPEGs with 100 percent and AdobeRGB-TIFFs with 16-bit without compression.

There is a lot at stake for Adobe in Lightroom Classic. Photoshop, on the other hand, saw a massive increase in performance when it was optimized for Apple Silicon, which had to blow us away with its GPU, filter, and especially its Photo Merge scores in Puget Systems’ PugetBench benchmark. When Lightroom for M1 was released in December 2020, we found meager performance gains, far beyond what M1 was already able to achieve with the Rosetta 2 emulation of the Intel version. Our experience with Apple Silicon-optimized apps from Adobe is 50/50 so far. The latest version of Lightroom Classic was up to 25 percent faster on the M1 than on our more expensive Intel-based Mac. Could Apple’s M1 processor give photographers a big boost in performance? In short: yes. Our hopes were high for a program that was so notoriously sluggish. This morning Adobe unveiled the long-awaited version of Lightroom Classic, which is fully optimized for Apple Silicon devices, and we had the chance to test it out before it was released. ![]()
