When MediaTek announced that it's working on a true eight-core mobile processor, we knew it was only a matter of time before main rival Qualcomm chimes in. As illustrated by a set of guitar amplifiers, the San Diego gang explains that while they rebuild their CPU cores for each generation (the latest architectures being Krait 300 and Krait 400), they claim that "Our Competitor" -- which is labeled with the same font and colors as MediaTek's logo -- simply "chooses to duplicate the same old cores" based on ARM's Cortex-A7 architecture.

Following that, Qualcomm uses a Guitar Hero-like video to visualize the performance difference, as well as to show how octa-core is overrated for most apps -- apparently only 17 out of the top 20 Android apps in China use two cores at most. Hence the bare fretboard for the octa-core side, while the Snapdragon side combs through a denser bunch of apps at a higher speed. The video's right after the break, so enjoy!
