Apologies if I’ve missed it what with all the talk about CPU throttling but any comparison of these dGPUs which I understand are just different clocks?

If your application puts GPU load then yes, it will be faster. Not sure how significant the difference will be. Maybe you can find an 555X user to run some representative benchmarks for you.
 
They're basically overclocked versions of the chips from last year's model, which were pretty similar in performance, with the only big change being the base model has 4GB of VRAM like the upgraded version (last year the base model only came with 2GB), so I'd expect the performance gap to be even smaller than it was last year.

This chart puts them in the context of how well they perform against other laptop GPUs. The 560 from last year is the 113th fastest card on the list and the 555 is the 124th fastest. The higher end card is faster, just not by a whole lot.

Great link. Sure looks like Nvidia has the hot chips now. But I imagine they suck a lot more power

Yeah, these chips are very nice for their power bracket actually. You're not going to play modern games smoothly at high settings, but not everybody needs to game at high settings. I think a lot of people are cool with playing games at low/medium settings so they can have a quiet machine that doesn't require a giant power brick.

Thanks for this, so leaning towards not upgrading to the 560x and using the money towards AppleCare.
 
The 560X is apparently just about comparable to a GTX 1050... if you’re feeling generous. The upside is the Radeon chips come with 4GB VRAM standard whereas the 1050 has a 2GB option (which seems to be being offered less and less outside of really bare bones gaming machines). A 555X you’re talking between a GTX 950M and 960M so very base. Probably about equivalent to a MX150

I'm not sure why you wouldn't opt for the better GPU if you use SolidWorks. It is pretty heavily GPU reliant to my knowledge.
 
Any real world comparisons of the two using the same laptop spec?

I know it’s not an ideal benchmark but say Fortnite...does the 560x eek out a few more FPS?
 
So are there any comparison videos out yet of the same MBP but one with the 555x and the other with 560x?
