Qualcomm Snapdragon 7c

Qualcomm SD 7c

The Qualcomm Snapdragon 7c Compute Platform (or SD7c Gen 1) is a ARM based SoC for Windows laptops. It integrates two fast Kryo 495 Gold cores (based on the ARM Cortex-A76 architecture) at up to 2.4 GHz and six small Kryo 495 Silver cores (ARM Cortex-A55) for power efficiency. 

The successor is the Snapdragon 7c Gen 2 which offers slightly higher clock speeds.

The integrated X15 LTE modem supports Cat.12 download (600 MBit/s) and Cat.13 upload speeds (150 MBit/s). Furthermore, Wifi-5 and Bluetooth 5.0 are integrated in the SoC. In addition to the Adreno 618 graphic card, the SoC also integrates a Hexagon 692 NPU.

The chip is produced in 8nm (compared to the more modern 7LPP process of the 8cx) and intended for the use in thin and light laptops without a fan.
