Qualcomm announced the Snapdragon 670 system-on-chip (SoC) as the successor of the Snapdragon 660 SoC last year. The new chipset was built on the same 10nm process that the company had previously adopted for the Snapdragon 710 and Snapdragon 845. The San Diego-based company also delivered the Kryo 360 processor along with the Adreno 615 GPU and Spectra 250 ISP. Furthermore, the Snapdragon 670 includes the Snapdragon X12 LTE modem which is touted to support download speeds of up to 600 Mbps and upload speeds up to 150 Mbps.
There is also the third generation AI engine from Qualcomm that is claimed to deliver up to 1.8 times the performance of artificial intelligence (AI) than the previous generation. The Snapdragon 670 SoC is currently available for OEMs, although it will be available to end users later this year via mobile devices from the mid-market segment.
Qualcomm has supported full-HD + displays on the latest chipset, in addition to supporting up to 4K for external displays. The Snapdragon 670 SoC supports up to 16 GB of RAM and eMMC and UFS 2.1 storage. The available X12 LTE modem on the SoC enables automatic switching between LTE and Wi-Fi – depending on which mode has the most robust signal quality and the highest speeds at that moment. The X12 modem is designed to support download speeds up to 600 Mbps, and upload speeds up to 150 Mbps. In the same way, phone manufacturers can enable the new modem even to combine the LTE and Wi-Fi connections to boost download speeds.
In addition to the support for high-speed LTE networks, the Snapdragon 670 features the third-generation AI engine that delivers up to 1.8 times faster performance when using AI applications. There is also the Qualcomm Hexagon 685 DSP that is claimed to be ideal for computer algorithms. The AI Engine, in particular, supports various frameworks and tools such as Qualcomm Neural Processing SDK and Hexagon Neural Network (NN), as well as Caffe, Caffe2, TensorFlow, and TensorFlowLite among others.
The Snapdragon 670 SoC has Qualcomm’s Quick Charge 4+ technology for faster charging. This is classified to provide 50 percent of the power in 15 minutes of charging time. The SoC has also integrated Wi-Fi 802.11ac with Mu-MIMO, Qualcomm Aqstic audio technology, and aptX, Bluetooth v5, and support for six satellite systems including GPS, GLONASS, Beidou, Galileo, QZSS, and SBAS.
