    The 15 has fans in both the base and screen and a higher TDP spec (lookup the I7-8650u Intel spec sheet on "tdp up") bringing the base clock to 2.1. But you may prefer the higher portability of the 13.5.

    Thanks for that. I looked into it further and yes the 15 inch can pull higher wattage 20W as opposed to 15W on the 13.5 for sustained workloads. Performance will still be close between the two regardless.




    Still undecided on which one to get. I like that the 13.5 i7 is fanless and the portability. The GPU on the 15 is nicer but i dont really have a need for it. I mainly tele-conference and take notes while doing so the extra inches on the 15 would be better so i thought.

    After comparing i was shocked by not seeing that big a difference between the two screen sizes.

    I think the 13.5" is far more interesting since it packs more power than a traditional 13" laptop and has even more screen real state thanks to the 3:2 aspect ratio. The 15" is certainly good, but I think it isn't for me since I don't need the extra power.

    I agree. The 13.5 SB2 is slightly larger (almost the same) screenwise as a 14 inch 16:9 trational laptop. The 15 inch SB2 is the same size as a traditional 15.6 laptop. (Check my earlier post).

    I actually like the fanless aspect and from the video and notebookchecks review without a fan the 13.5 inch machine can operate well over the 15W TDP and run over 2GHZ for long periods underload.

    Check the review here:

    The GPU is stronger and you will get better wattage and higher sustained clock rates due to the fan in the 15 inch. How much more though?

    Agreed. Compared to other 15 inch devices, you can get desktop like performance from 2 in 1 from Lenovo and soon from Dell and HP.

    There is nothing out there too compare to the 13.5 inch. Even compared to a Mac the 13.5 blows the door s of any 23 inch MBP but the 15 inches have very similar performance except the gpu

    I have a power base version of the original 13.5 book that is my standard carry-along machine. I have 15" Book 2 that is my preferred home laptop. The 15 is clearly the better machine, but it's just a little large for easy transport. A tighter 15" case might make it easier to port, but the oversize 15' carriers just get too bulked up when you add a bunch of accessories.

    i went with the 15"model. There are other laptops out there that can get similar performance, especially in the price range. Being a Microsoft fan I prefer their product. Another good reason is the pen support and the tablet mode. The tablet half weighs even less than a SP. I prefer that over folding a laptop 2 in 1.
