Inside BlackBerry's Z30 is a Snapdragon S4 Pro. That's a Qualcomm system-on-chip with two Krait application cores and an Adreno 320 graphics processor. That's a perfectly acceptable CPU/GPU combination, but Samsung's is better and faster. The Galaxy S4 has a quad-core Qualcomm Snapdragon 600 with four Krait application cores running at 1.9GHz. And the Snapdragon 600 employs a speed-enhanced version of the Adreno 320. Both come with 2 GB of memory for running applications and the operating system, and both come with 16 GB of storage that can be expanded by 64 GB via microSD card.
