I also think that RAM has been the biggest limiter on the 2015 MBA 11". If they had offered that in 16GB at the time, it would have been very, very powerful. There wasn't even a question in my mind that I'd put 16GB on the MBA I just ordered. I'm a bit surprised Apple is still selling 8GB. It feels like when they were selling their 16GB iPhones--stingy and not in the best interests of the customer even if it offers a lower pricepoint.
If my 2016 11" air had 16GB of ram, I think it would have been harder to justify this upgrade because much of the time I can't see the retina screen when I'm docked, nor use the touch ID.
So I am now very curious about how thermal / IO / GPU performance on this machine. Can you recommend any sites that do some of the tests you're describing? I'll run the tests when the machine arrives Wednesday and compare them directly w 2015 MBA 11".
I'm now starting to understand why Apple cut the 11" MBA in 2015. The price and performance was actually too good. Price wise it competed too directly with the retina macbook and was on track to perform better than the MBP line. If they had kept selling it, I don't think they would have sold many nTB MBP 13's as people opted for the old keyboard, old screen but won on processor / ram / graphics performance.
It isn't talked about, but I really do think the removal of the 11" MBA in 2015 left a gaping performance / price hole in Apple's portable line. I don't think it will be filled again until we see this ARM machine.
There are a variety of tech sites and YouTube casters who cover tech. I generally read and watch widely because sometimes the chipsets, rather than specific Mac devices, are what is being reviewed. You could try some sites like ExtremeTech and NoteBookCheck. I also appreciate YouTubers Lisa on MobileTechReview and Dave Lee on D2D. There are plenty of other tech enthusiast sites and forums (HotHardware, HardOCP, ArsTechnica, AnandTech, etc). I have found no one site or group of sites that covers everything. Just keep your eyes and ears open.
