This post is just a FYI for those that may be interested...
At the moment I have both a 2014 15" MBPR (2.2 GHz) and a 2015 MBR (1.1 GHz). Occasionally I will rip blu-rays and transcode them on my MBPR with Handbrake on OS X. On the MBPR I will achieve around 22-24 FPS. I did a quick test on the MBR yesterday and achieve around 5-6 fps under OS X. This morning I installed Win 8.1 under Bootcamp and ran Handbrake with Quicksync enabled. 10% into transcoding 3:10 to Yuma it is averaging 18.1 FPS with lookahead enabled. Instantaneous framerate is about 10-12 FPS so I expect the average to drop considerably.
Using Intel Power Gadget
Package Freq: 0.8 GHz
GPU Freq: 700 MHz
Package Temp: 58C
It's no surprise that the MBR just isn't cut out for significant 1080P transcoding work but I thought I'd share the data and save some of you some time.
I think I'm going to keep the MBR and sell the MBPR. I'll either let encodes run all night or put together an inexpensive Core i7 setup purely for the transcoding applications.
On another note Lightroom 6 runs very well on the MBR. The GPU acceleration really makes the difference and should be adequate for most non-pro use. I disabled the GPU acceleration and saw a very noticeable difference.
Later!
