New Snapdragon 412 and Snapdragon 212 chipsets offer incremental improvements21
Let's start with the Snapdragon 412 SoC. Qualcomm has raised the maximum clock speed on the 64-bit capable Corex-A53 cores to 1.4GHz. And while the Adreno 306 continues to handle graphics, it too is running faster as compared to the clock speeds employed on the SD-410. The latter ran its four Cortex-A53 cores at a max of 1.2GHz. Manufactured using the same 28nm process as it predecessor, the Snapdragon 412 supports screens with a resolution of 1200 x 1920. The chipset also features QuickCharge 2.0, and can handle video playback from 13MP cameras. It also offers X5 LTE connectivity (Cat.4, 150Mbps), along with support for Wi-Fi, b/g/n, Bluetooth 4.1 and USB 2.0.
The Snapdragon 212 bumps the clock speed of the four Cortex-A7 cores to 1.3GHz from the 1.1GHz used on the Snapdragon 210. The Adreno 304 GPU returns, and the chipset is built using the 28nm process just like the SD-210. The new chipset supports screens with a resolution of 720p, and will also handle 1080p video in H.264 and H.265. Devices powered with this chip can employ up to an 8MP camera. Connectivity options include Cat.4 LTE, Wi-Fi b/g/n, Bluetooth 4.1+ BLE, USB 2.0 and Quick Charge 2.0.
Both chips should soon find their way inside upcoming handsets.
