The CPU is more power efficient though with 14nm snapdragon 630 on XA2 vs 28nm snapdragon 650 on Xperia X. XA2 memory is at 1333MHz vs 933MHz on X. Having it in hand now, i can not wait to have edge swipe on that thingy. The left and right edges feel like made with edge swipe in mind tbh. On Xperia X, only the glass is curved but on XA2 i get actual N9 feels! (- the size) The XA2 is only marginally bigger than X, but 20g heavier, 170g vs 150g. The screen size of 5.2" fitted on near same space than 5" Xperia X makes it look more advanced. Less bezel overall. Ah, and connectivity options are more recent. Cat13 LTE (600Mbps) is possible on XA2 vs Cat6 (300Mbps) on X https://www.gsmarena.com/compare.php...&idPhone2=7948 https://versus.com/en/qualcomm-snapdragon-630-vs-qualcomm-snapdragon-650
