Hi, I am a full time pro who has been in business for nearly 30 years, I shoot commercial advertising and editorial work on digital, fine art black and white on film using a darkroom. I use Nikon, Leica and Hasselblad for both digital and film work. For the most part, my workflow is tolerable as I use very little if any photoshop in my work, get it right in camera. But the two things I want to see improved are thumbnail render times and most importantly the time in which it takes to convert raw files to either TIFF or JEPG ( depends on the client, ad firm likes TIFF, New York Times likes JPEG ). I'm using a 13" Retina from 2013 and a fairly built up MacPro from 2012. I am considering upgrading the laptop to a maxed out 2017 15" but I really need to get into the nuts and bolts of just how much faster is this going to be at rendering thumbnails, processing 24MP, 36MP and 50MP RAW files from my cameras? There is just not a heck of a lot out there, it's all 3-D rendering, gaming and other tech-head benchmarks. So when one figures in all the usual Moore's Law type of incremental speed increases and how they actually apply to the real world, how does this actually bear out in plowing through hundreds of RAW files on a job, would the new 15" maxed out cut my export times in half of what they would be with my 2013 Retina or....what?
