It's incredibly powerful. I just unboxed it and I can really feel the power of the M5 Pro chip. With its dedicated cores, it's definitely an excellent investment for professionals in editing or architecture. These Apple chips deliver insane performance, and the 48GB of RAM will give you peace of mind.
