This is for the base model MacBook. I did things the average user might do, so I avoided 4k video or RAW files in this test. Here are the results:
iMovie: 10 minute clip. 1920x1080i 24Mbps, 30fps. Took 1:02 to import. Trimmed to 4 minutes and exported to file. 1920x1080 and default medium setting 410MB file. Took 9:10, not bad considering the 2015 rMBP 13 base model I did this same test with took 7:12 to export, not too far off. I noticed zero lag or stuttering in the playback window which REALLY surprised me considering the rMBP 13 stuttered quite a bit in the same test.
Photoshop CS6: PS opens very quickly, 3 seconds and another second top load the photo. 3456x5184 2.7MB photo. Didn't get to crazy, just doing a few things an average use might do. Resized to 1600x2400 instantly, ran Portraiture 2 filter under default low shooting setting, applied it in a second. No noticeable lag using any tools. No lag using any tools within liquify either. No batch test yet as most average users won't do that, but I still want to see.
Preview opened all 477 pics (1.08GB file) within a second and going thru them produced no lag, even when doing so quickly. I must say I am impressed. I would never use this as my main machine for photo and video editing but the average user should have no problems with editing photos or video with even the base model. Good news!
