Swizzle Bench Runtime Nexus 6P xxx_xxxa 0.32x xxx_swaprb_xxxa 0.31x Swizzle Bench Runtime Nexus 9 xxx_xxxa 1.11x xxx_swaprb_xxxa 1.14x (This is a slow down.) Swizzle Bench Runtime Nexus 5 xxx_xxxa 0.12x xxx_swaprb 0.12x RGB PNG Decode Runtime Nexus 6P 0.94x Nexus 9 0.98x I don't know how to explain the fact that the Swizzle Bench was slower on Nexus 9, but the decode times got faster.
