new MBPr 13 vs old MBPr 15

Dear fellow Apple fans,

I googled "new mbp 13 vs used mbp 15". I could not find a similar discussion. Please forgive me if there is already such discussion.

My boss just gave me his MBPr 15" 2012 model. It was a high end model fours years ago with I7 (Ivy Bridge) CPU, 16GB RAM, 512GB SSD. It seems still worth $1000+ on eBay.

The question is: should I sell it to purchase a new MBPr 13"? Especially the one is coming soon?

Which one would you choose? Or is it simply a choice of screen size vs newer technology?

Thank you very much for any suggestions!

May the Mac updates coming SOON!

Really depends on what you do. The 15" is likely going to be faster in CPU and GPU intensive tasks, but it's bigger so it's less portable. Which do you need/appreciate more, performance or portability?

I regret buying the 13" model because of the low performance (dual-core vs. quad-core) and small display. For CPU intensive tasks the 15" from 2012 will be faster! I'm not sure if this is important for you because this depends on your needs.

Thanks to everyone! I am a little surprised that a four year old quad-core Ivy Bridge i7 CPU still out-performs a dual-core i5 Skylake. Well, CPU technology hasn't changed much. I guess.

Thanks for letting me know the performance difference. I will probably stick to the MBPr 15 then. Never had the luxury of 15 before.

If the machine currently meets your needs, why bother selling it? No need to upgrade unless you NEED to upgrade.

That's my philosophy too. My current one is a mid 2010 MBP 13. 6 years old and still will run macOS Sierra. As long as it runs the newest software, I don't really need to upgrade. Same applies to my iPhone.
