Head-to-Head: BlackBerry Z10 vs. Apple iPhone 5

CPU, GPU and Memory

With its dual-core TI OMAP 4470 system-on-chip, the Z10 starts out in a bit of a hole against iPhone 5's quad-core A6 custom SoC (but it's directly on par with the iPhone 4). Both devices use ARM Cortex A9 application processors; BlackBerry's run at 1.5GHz and Apple's at 1.3GHz. BlackBerry has the edge on system RAM. The BlackBerry 10 OS and its apps will have 2 GB of RAM in which to spread out and run, doubling that of iPhone 5's 1 GB. The BlackBerry comes with 16 GB of storage that's expandable by 64 GB via microSD; iPhone 5 comes with 16, 32 or 64 GB and isn't expandable once purchased. On the graphics front, there's relative parity between BlackBerry and iPhone. Both use multicore PowerVR GPUs from Imagination Technologies and both support 1,080p capture and playback at 30 fps. The BlackBerry's OMAP SoC has the SGX544 GPU with an IVA 3 multimedia accelerator. The A6 chip in iPhone 5 incorporates the PowerVR SGX 543MP3, which Apple claims that when combined with its ARM cores doubles application and graphics performance from the previous generation's A5X, the SoC in iPhone 4.
