Qualcomm Snapdragon 7c vs MediaTek MT8188J

Qualcomm Snapdragon 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.

MediaTek MT8188J

The MediaTek MT8188J is a mid-range ARM SoC (System-on-a-Chip) introduced in the first quarter of 2023, primarily used in Android-based tablets. It is manufactured using a 12-nanometer process and features a total of eight CPU cores (Octa-Core). These consist of two fast Cortex-A78 cores and 6 Cortex-A55 cores that work together in a big.LITTLE configuration.

The A78 cores of the MediaTek MT8188J can clock at speeds of up to 2.2 GHz, while the A55 cores can reach speeds of up to 2 GHz (going down to 500 MHz). For graphics processing, it employs an ARM Mali-G57 MP2 GPU. Additionally, it includes a video decoder with support for H.264 and H.265.

In addition to the CPU and GPU, the chip integrates an LPDDR4 memory controller, capable of supporting up to 8 GB of RAM. The SoC also includes a modem for WiFi 6, Bluetooth 5.3, and LTE up to Cat.7.
