Qualcomm previously said it would focus on faster cores instead of more cores, but this year the company reveals the 64-bit Snapdragon 615 with eight Cortex A53 cores. The company explained the move by pointing to market research studies that show Chinese consumers prefer more cores, even if they don't make a big difference. The new series also includes the Snapdragon 610, a quad-core Cortex A53 chip.
The Snapdragon 610 will be equipped with four ARM Cortex A53 CPU cores running at an unspecified clock speed, rather than one of Qualcomm's custom ARM architectures. Snapdragon 615 takes a classic more-is-better approach, adding four more Cortex A53 CPU cores to the 610 for a total of eight. (Update: According to AnandTech, each group of four cores in the Snapdragon 615 will be optimized for a different performance level. One group will offer faster performance and one will offer lower power consumption, but both groups can theoretically be active at the same time.) For reference, the original Snapdragon 600 included four 32-bit Krait 300 CPU cores running at 1.7 or 1.9GHz, depending on the specific model.
