surpriiiise!
Wonder who's going to release 2560x1600 displays for arm Laptops. As far as I can tell, that is probably the only thing holding ARM laptops back from taking off.
yyehhh... the bandwidth's just.... let's do the maths. assume a 60fps refresh rate? so 2560*1600*60*4 (bytes per pixel=32) we're looking at 983mbytes/sec.
i'd guess that 983mbytes/sec would utterly overwhelm most ARM processors internal memory bus architectures.... and that's just for refreshing the display - it's not even for *updating* it.
so it's pretty hard-core.
the current focus of design - because it's where the money is - is on "IPTV" and "tablet". do a quick scan of what allwinner sells: all their products are either "TV" or "Tablet", with the occasional "tablet-that-thinks-it's-a-smartphone" SoC thrown in.
in other words, i feel that when tablets start getting 2560x1600 displays, and those become popular enough to catch allwinner and rockchip's attention, we might start seeing SoCs that support that kind of resolution.
