Hi everyone, I am going to buy a 2015 Macbook pro 15 inch and I was choosing the model. I saw that there are 3 different cpu and I was interested about the 2,5Ghz and the 2,7Ghz.
My question is: is the difference really noticeable between the two?
I would use it manly with Photshop (sometimes with very big files), Illustrator, indesign, premiere and maybe some after effects and 3d modelling.
which one would you think would be the right one for me? is the 2,5Ghz good enough for my needs?
thank you very much =)
 
yes of course I would choose the model with dedicated GPU
 
All have dedicated GPU. Base 2.5 with 460 would be more interesting than 2.7 with 455.
 
I was looking on the apple website and it seems that now are only avalible the models with the integrated GPU intel iris pro graphics
 
For the 2015 models yes, the dGPU versions got replaced by the 2016 series.
 
You're right, I got confused. You can still get the dGPU 2015 elsewhere, just not from Apple anymore.
 
Is the gpu of the 2015 model good enough for you? Is there just one model? Or are there some (as 2016 models)?
 
2015 only has the M370X, based on an older chip and it performs slightly less than the 2016 PRO450.

I went with the 460 and have no experience with the older and lower models. Just went with the upgrade since I'll be doing 3D work as well. The 370 or 450 would have been good enough I guess.

The 3D work is mainly realtime animated projections for theatre. Most of time I don't do heavy models, but more with textures and animated planes etc. Developing the programs worked on my 2008 model, but rendering anything more than a 20% window was dramatic even on the low-res screen.

With the 2016 base model, a <10% price increase gives like 30/40% more 3D performance and I think it'll be worth it in a few years. I'm sure the extra video RAM also helps.

(I have never tried 3D modeling but maybe in the future I'd like to try, it won't be anywyay my main work)

The dgpu model for the 2015 will be available in the refurbished store, keep checking. As far as the CPU speeds go, no, you will not see much difference at all. I tried out both 2.2 and 2.5 ghz models and noticed no difference in performance. From the benchmarks there is no noticeable difference between 2.5 and 2.7.

Definitely hold out for a refurbished model as they will show up in stock any day, they are as good as new and you will save a lot of money.

I found 2 good deals on apple refurbished store, they are the 2015 model, one with 2,5ghz cpu and the other with 2,7ghz cpu. do you think it's better to go on the faster processor? does it change anything with a faster processor(for example the battery time is shorter or anything?)
 
Save your money and get the 2.5 GHz 2015 model. No meaningful difference from the 2.5 to the 2.8.
 
thank you! would you suggest me to go on the new or wait for some refurbished model?
