Qualcomm released the mid-range chip product Snapdragon 678 yesterday, which is a follow-up product of the Qualcomm Snapdragon 675. It uses a 11nm technology, but it still does not support 5G networks.
The Qualcomm Snapdragon 678 uses the Kryo 460 CPU. The main ARM Cortex-A76 core’s frequency has been increased from 2GHz to 2.2GHz. It also integrates Qualcomm’s own Adreno 612 graphics processor, and there is no change in parameters.
Other parts of the Qualcomm Snapdragon 678 are consistent with the Snapdragon 675, including the Spectra 250L ISP, the Snapdragon X12 LTE modem and the Hexagon 685 DSP. Therefore, the Snapdragon 678 still cannot support 5G networks, and the theoretical downlink/uplink rates are 600/150Mbps respectively.
There is a dual-SIM VoLTE and 3x 20 MHz downlink carrier aggregation support. Other features include 8GB DDR4 RAM at 1,866MHz support, video playback up to 4K with HEVC, AVC codec support, Qualcomm aptX, aptX HD, Quick Charge 4+ technology, and more.
The Qualcomm Snapdragon 678 mobile platform also supports 2520×1800 (FHD+) resolution screen, 48MP main camera, and 4K@30fps video shooting.
Like the Qualcomm Snapdragon 675, the Snapdragon 678 also uses the 11nm process node. Therefore, in terms of parameters and technology, the Qualcomm Snapdragon 678 can be regarded as a small improvement version. A higher frequency can theoretically provide better performance, but the impact should be small.
We should see the first devices coming with it in the next year. Hopefully, it will be the natural choice for 2021 devices over the Snapdragon 662. Unfortunately, most OEMs tend to choose the less capable chip for mid-range phones and go with the SD7xx for devices beyond the mid-range segment.
