I actually feel offended by your comment and may i say this, it's a snobby comment. Though it gives me comfort to think that you felt the need to make it.
"This card is expected to carry just 2 GB of memory..." Why would you want more VRAM on a mid-range card that most likely won't be able to handle more than 1080P and maybe 1440P (if you're lucky) anyway?
In summary Maxwell kicked AMD right square in the nuts and if you can't beat em join em.
Power efficiency seems to be the trend of the day. Intel makes more power efficient CPUs. ARM makes more power efficient CPU so does AMD (the new low cost versions like puma, not the old FX line...)
Nvidia start to make more power efficient GPUs and AMD is also moving to the same direction... Summa summarum, it seems that CPU and GPU are powerful enough at this moment, so it is better to concentrate to power efficiency.
Good for consoles, tablets and other mobile devices, is it good for PC gaming... I just wonder.
