According to Qualcomm, the current generation Snapdragon has 170% faster CPU performance than the OG Snapdragon chips. While specs fanatics like to talk about the CPU, it makes up only 15% of the Snapdragon SoC which also includes the GPU, 4G LTE, DSP, Camera and Connectivity.
Why does Qualcomm feel the need to discuss quality vs. quantity of cores? Well, it might have to do with the MediaTek MT6592, the world's first true octa-core processor. Unlike the Samsung Exynos, which only has one group of four cores active at any given time, the MediaTek MT6592 uses all 8 cores at once. Mass production is scheduled for November.
Meanwhile, kudos to Qualcomm for producing an entertaining and quite visual video that gets its point across in a way that is perfectly suited to the demographic it is trying to reach.
