#Adobe photoshop apple 1.5x photoshop intel updateIf it were to scale perfectly and to use the 2 efficiency cores also, it would plummet to about 4 seconds.īelow, the MacBook Pro M1 Max single-threaded Smart Sharpen makes it 3.5X to 2.5X slower than other Intel Macs.Adobe has been moving quickly to update its imaging software to work natively on Apple’s new in-house processors for Macs, starting with the M1-based MacBook Pro and MacBook Air released late last year. #Adobe photoshop apple 1.5x photoshop intel macIf it were fixed to use all 8 high performance CPU cores *and* it scales efficiently, it ought to be about 7X faster, plummeting the 35.4 second figure shown below to about 5.1 seconds, which would be about twice as fast as even the 28-core 2019 Mac Pro. And it’s not the only area-fast as it is, Enhance Details makes poor use of CPU cores also. #Adobe photoshop apple 1.5x photoshop intel codeIronically, running PS in emulation mode (Rosetta emulation) is 3.2X faster, with a time of 11.0 seconds with 6.5 CPU cores used! Looks like a bug in the threading code in Photoshop. And maybe not-maybe it is assumed that the GPU with OpenCL does the trick. The good news is that maybe Adobe will fix it. On my 2019 iMac 5K, all the CPU cores get used for Smart Sharpen, see image further below.īut Smart Sharpen with openCL disabled is single-threaded on Apple Silicon in Photoshop (only one CPU core is used). But what if your most common Photoshop Filter is 3.5X slower? Why is Photoshop Smart Sharpen single threaded on Apple Silicon? Nearly all of the time it is incredibly fast. So while the Apple M1 Max chip can be very fast (amazingly so) for most everything and perhaps the biggest leap in computing performance I have witnessed in 30 years, it also underperforms for a few things. This is not a hardware fault in this case it looks like Adobe has goofed (a bug). Ditto for hashing speed, which is slower than a 7-year-old 4-core Intel laptop. But I don’t use any of those filters! So their weighting/relevance is a zero as far as what photographers are likely to care about.īut Photoshop Smart Sharpen on Apple Silicon is a big loser*. My tests show that the M1 Max wins handily for Lens Corrections, Distort, Blur, Pixellate, Noise and various others, by a little or a lot. That might be true for some Consumer Reports-style weighting of filters I never use and most people are likely to never use (Distort or Pixellate, anyone?). So along come claims (including Adobe) saying that the Apple MacBook Pro M1 Max is 1.5X faster than Intel-based Macs for Photoshop. Nothing else comes close, and it is the thing that most often makes me wait. The Smart Sharpen filter is the #1 most important filter I use in Photoshop. I also see both poor CPU and poor GPU usage on the MBP M1 Max in some tests, suggesting that even better results should be possible. And it’s strange that an emulated Photoshop (Intel version via Rosetta) is just about as fast as the GPU.īut in the course of comparing OpenCL on vs off on the MBP, I found that for some filters OpenCL is actually slower when enabled than disabled! Sometimes a little, and sometimes a shit-ton: my Noise filters (Dust And Scratches and related) are running 4.4X slower with OpenCL enabled! Also, with OpenCL enabled, I am seeing erratic (varying and slowing) times across iterations of a test. Still, what follows below is still correct for the MacBook Pro in terms of CPU usage, should you turn off OpenCL. I had turned it off because of stability issues some time ago. UPDATE: regarding the original post below: well, I goofed-Open CL was turned off for all the machines, causing the GPU to not be used for Smart Sharpen.
