I was just reading this article on Petapixel.

Apple’s First 8-Core MacBook Pro Runs Photoshop Up to 75% Faster

I "thought" most photoshop processes only run sequentially and do not multitask. Thus it would only use one core at a time, versus many cores at the same time. There are a number of articles online that go back a number of years that all say other than a few filters, most tasks in Photoshop do not use more than one core.

Is my knowledge wrong? I have a 2017 MBP. I'd seriously consider getting the new machine if it really ran photoshop 75% faster.

Thoughts?

Straight from Adobe:

"Photoshop generally runs faster with more processor cores, although some features take greater advantage of the additional cores than others. However, you’ll get diminishing returns with multiple processor cores: The more cores you use, the less you get from each additional core. Therefore, Photoshop doesn’t run four times as fast on a computer with 16 processor cores as on a computer with four cores. For most users, the increase in performance that more than six cores provides doesn’t justify the increased cost."

You might see a nice boost with an eGPU, if you don't want to upgrade your entire computer.

75% faster than what? If it's a dual core 2012 machine with 4GB of RAM, then that's considerably less impressive than it being 75% faster than some recent, top spec, next best model.
