So I'm currently standing between two choices of macbook pro's. My need is to be able to hook up my macbook via thunderbolt 2 to a dock, and from the dock connect it to a monitor and obtain 4k@60Hz (+ other peripherals). I aim to use this for Xcode, general programming (data science and AI), Matlab, Eclipse, R, Python and watch videos in 4k, thus any sort of lag or klick-delay is very undesirable.
I don't care much about the haptic track pad and esthetics. Also the amount of storage is not important either since I use external SSD or NAS.
Which of the following should I choose, all things (except price) considered?
Macbook Pro Retina 15'' mid 2015:
- Intel core i7 @ 2.5 GHz
- 16 GB @ 1600 MHz DDR3
- 512 GB flash SSD
- Intel Iris Pro 1536 MB
Macbook Pro Retina 15'' mid 2014:
- Intel core i7 4870HQ QuadCore @ 2.5 GHz (3.7 GHz turbo boost)
- 16 GB @1600 MHz DDR3L
- 240 GB flash SSD
- NVIDIA GeForce GT 750M 2GB GDDR5 + Intel Iris Pro 1536MB
To me, the 2014 version seem to be better, but I feel like I'm missing something that the specs aren't covering. Also the 2014 model currently has 0 bids while the 2015 has like 50 bids. Why does the 2015 seem to be more attractive to people if the 2014 has better specs?
