The video takes a widely used system-level benchmark and runs it through its course comparing the Qualcomm Snapdragon 400 processor with 1.2GHz custom designed, dual-core Krait CPUs with a competitor's 1.2GHz quad-core processor. This particular benchmark tests all the major components in a processor (aside from the number of CPU cores), including memory, I/O, and 2D/3D graphics. The scores speak for themselves, which goes to show: More CPU cores doesn't necessarily mean better performance.
