Sustained performance in a smartphone thermal envelope, remember! How long do you think a 4.5" device can keep an A15 high clocked? We've all seen some fairly impressive benchmarks of the later revision A15s, but most of those have been in e.g. the Shield Tablet, where it has a 8" sheet of metal inside it to act as a heatspreader: http://images.anandtech.com/doci/8275/SHIELD_tablet_Exploded_View_white_bckgr_678x452.jpg
