This new chip might not only keep costs down by using older production techniques, but could give phone makers a reasonably fast chip if 888 supplies are tight. While it's possible Qualcomm eliminated Wi-Fi 6E from the Snapdragon 870 specifically to avoid overcrowding its mesh networking backhaul, we really don't know; we reached out to Qualcomm and didn't hear back by press time.
Qualcomm will probably present the new Snapdragon 870 5G Mobile Platform later in the day, but all the important details have already been made public. While the 870 is an improvement over the 865 Plus, the Snapdragon 888, which features more powerful components like the Kryo 680 cores and a Snapdragon X60 5G modem, will remain the company's most powerful chipset. The 870 is designed for companies that want to offer a top-tier processor but don't need the absolute best features that the flagship Snapdragon 888 offers and the higher price tag that it demands.
It says the new chipset is a follow-up to the Snapdragon 865 series. Plus, it offers widespread accessibility with support for mmWave, Sub-6 GHz, TDD, FDD, and Dynamic Spectrum Sharing (DSS). Commercial devices based on Snapdragon 870 are expected to be announced in the first quarter of 2021. The newly launched chipset features an enhanced Qualcomm Kry 585 CPU prime core clock speed of up to 3.2 GHz. In saying so, it looks like the Snapdragon 870 lacks the FastConnect 6900 connectivity suite seen in the 865 Plus, opting for the 6800 suite seen in the original Snapdragon 865 instead.
The Snapdragon 870 supports up to 16GB of either LPDDR5 or LPDDR4x memory.
