The chip uses several different fabrication technologies, namely system-in-package and package-in-package, with the fun acronym SiP-ePoP. That helped engineers squeeze in the DRAM, NAND flash and power management chips, while reducing the total height, to boot. It also jammed WiFi, Bluetooth, an FM radio and a GPS (GNSS) receiver into the 100 millimeter square (0.155 square inch) device. Overall, it's 20 percent more power efficient than last-gen 28-nanometer tech, Samsung says.

That should yield wearables that let you take calls or tether other devices over LTE and WiFi. Smartwatches or fitness trackers will also get GPS tracking and more without a huge power hit or need for a smartphone. To help developers get on board, Samsung has released a developer platform, but it could be a while before we see any devices that use the new chip.
