Which version of the Air was used? the base model with 8 core and 7 core GPU or the slightly more version with the extra GPU core 8 Core CPU and 8core GPU? Probably won't make a difference with one more GPU core but curious is all. VERY impressive to say the least. Can't wait to get it. Shipping can't come soon enough lol.
I'm pretty sure the base model M1 was tested. IIRC they said so; and second, so far as I know that is the only model available today. I ordered the 16 GB version for my wife and have a tentative shipping date a month from now.
One of the less publicized features of the M1 is
really fast RAM swapping (and 60 GB/sec on SOC communication, if you can believe it) so for most every day tasks 8 GB with Mac OS is a
lot better than 8 GB in a Windows computer. I'm not really sure that it is worth it to pay $200 for the extra RAM but it is now or never and we keep our Macs for a long time. I just hope that extra 8 GB RAM does not cause much of a hit on the stellar run time.
