Qualcomm Snapdragon 750G 5G vs MediaTek Dimensity 900 vs MediaTek MT8188J

Qualcomm Snapdragon 750G 5G

The Qualcomm Snapdragon 750G 5G (SM7225 Mobile Platform) is a fast mid-range ARM-based SoC largely found on Android tablets and smartphones. It integrates eight cores (octa-core) divided into two clusters. A fast performance cluster contains two ARM Cortex-A77 cores clocked at up to 2.2 GHz and a power efficiency cluster with six small ARM Cortex-A55 cores at up to 1.8 GHz. Depending on the workload only single clusters or all cores can run at different clock speeds.

The chip includes a range of other features like a fast X52 5G radio (3700 Mbits download including Sub-6 and mmWave), Wi-Fi 6 wireless radio (802.11ax), satellite positioning (GPS, QZSS, GLONASS, SBAS, Beidou, Galileo), USB-C 3.1, Spectra 355L ISP, Hexagon 694 DSP, H.265 4K30 video en- and decode, and a Adreno 619 GPU.

The G specifies an optimized SoC for gaming and e.g. Qualcomm offers updates for the graphics driver.

The Snapdragon 750G is manufactured in the modern 8 nm process at Samsung.

MediaTek Dimensity 900

The Mediatek Dimensity 900 is a fast mid-range SoC with an integrated 5G modem. It includes two fast ARM Cortex-A78 cores at up to 2.4 GHz and six power efficient Cortex-A55 cores at up to 2 GHz (Octa-Core with Heterogeneous Multi-Processing). Furthermore, the chip integrates a 4 core ARM Mali-G68 MC4 GPU, a Wi-fi 6 modem, a LPDDR4x memory controller, a AI processing unit  and video de- and encoding.

The Dimensity 900 is manufactured in the modern 6nm process and should be very power efficient.

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.
