What the heck is the X8? Motorola's new processing system powers the Droid Ultra, Droid Mini and Droid Maxx, and it's anticipated to be under the hood of Motorola's new Moto X, coming tomorrow.
The X8 isn't a processor, and it isn't a system-on-a-chip. It appears to be shorthand for combining a customized Qualcomm Snapdragon S4 Pro SoC with two DSPs, one of which can function essentially as a low-power CPU.
"If you look at the X8 mobile computing system, it has a cluster of processors and then some separate elements of the system," said Iqbal Arshad, Motorola's senior vice president of engineering. The goal was to move away from a primarily CPU-based architecture to save power and do "intelligent, probabilistic computing," he said.
But still, let's start with the CPU; it's the easiest part to understand. The X8's CPU is, basically, a 28nm Qualcomm S4 Pro running at 1.7GHz. Motorola has customized the chip's firmware, though.
