(*) there are benchmarks in Photoshop, but most sites do not have comparison between notebooks and desktops, unfortunately. But if you need a new system - well, any macbook pro or iMac you can get today is going to be faster than the one you have now. The speed increases in raw processing speed from one generation to another aren't as noticeable anymore as they were 5-10 years ago it's much more incremental steps now. Other functions in PS CC however do benefit from having a pretty fast graphics card in the iMac, so you may find that the speed increases in some areas of the program. Realistically, based on the mix of benchmarks I saw, I'd you knock off about 30sec of that 2,5 minutes.Īs far as I can find in Adobe documentation, the HDR functions do not use the graphics card to speed up processing, so there would be no additional gain there. Assuming 16GB of RAM and an SSD in the iMac as well, and the highest-end model with Core i7: the CPU will be between 30 and 100% faster (*) so best case scenario processing takes 1:15, worst case around 1:50, assuming the process is fully CPU bound (which is unlikely).
