Qualcomm Snapdragon 678 has been announced as the successor to the popular Snapdragon 675 mobile platform. The new processor for mid-range smartphones is designed to bring an improved photography and connectivity experience to the segment.
The new Snapdragon 678 is not hugely different from Snapdragon 675 with the main difference being the clock speed of the primary core. The octa-core CPU features the same 64-bit Kryo 460 core seen on its predecessor and also uses Snapdragon X12 LTE modem. However, there are some changes that improve imaging and connectivity without compromising the battery life.
Qualcomm Snapdragon 678: process and connectivity
Qualcomm Snapdragon 678 is built on a 11nm LLP process. On the Snapdragon 678 mobile platform, the Qualcomm Kryo 460 CPU is clocked at 2.2GHz. The Kryo 460 CPU on the Snapdragon 675 was clocked at 2.0GHz. In a way, the new Snapdragon 678 is basically an overclocked version of the Snapdragon 675.
There is also the same Adreno 612 GPU but Qualcomm promises faster graphics rendering with the new processor. It seems Qualcomm has optimised the chipset for Unity, Messiah, NeoX and Unreal Engine 4 for an improved gaming experience. This should also help with streaming videos and listening to music online.
For connectivity, Qualcomm is going with the reliable Snapdragon X12 LTE modem. It delivers peak download speed of 600Mbps and peak upload speed of 150Mbps. It supports advanced carrier aggregation, all major cellular modes and Licensed Assisted Access (LAA) for increased capacity.
Qualcomm Snapdragon 678: imaging and security
On the photography front, the Snapdragon 678 includes Qualcomm Spectra 250L image signal processor. It brings support for up to a 48-megapixel single camera with zero shutter lag and 25-megapixels at 30 frames per second. For a dual camera setup, it is limited to 16-megapixels with zero shutter lag. With this mobile platform, smartphone makers will be able to design phones with up to 192-megapixel sensors with zero shutter lag.
The dual ISP design is aided by the third generation AI Engine bringing features like portrait mode and low-light photography. It also supports laser autofocus so users can capture their subjects instantly. It supports 4K video recording at up to 30 frames per second on the HEVC codec. There is also support for 1080p slow-motion video at 120fps and 720p slow-motion video at 240fps.
The chipset supports maximum on-device display resolution of Full HD+ with display pixels up to 2520 x 1080 and colour depth up to 10-bit. It brings support for WiFi 802.11ac Wave 2, Bluetooth 5.0, NFC and USB 3.1 (USB-C). It supports Qualcomm Quick Charge 4+, Qualcomm mobile security and processor security.
