MediaTek MT8188J vs MediaTek Dimensity 920 vs MediaTek Dimensity 8200-Ultra

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.

MediaTek Dimensity 920

The Mediatek Dimensity 920 is a fast mid-range SoC with an integrated 5G modem. It includes two fast ARM Cortex-A78 cores at up to 2.5 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 5G modem supports Sub-6 GHz and dual SIM. The download speeds can reach up to 2.7 Gbit/s.

Compared to the older Dimensity 900, the 920 offers slightly higher clock speeds for the CPU and GPU.

The Dimensity 920 is manufactured in the modern 6nm process and should be very power efficient.

MediaTek Dimensity 8200-Ultra

The MediaTek Dimensity 8200-Ultra is a upper mid-range ARM-based SoC (system-on-a-chip) that is manufactured using the modern 4 nm process. It was specially designed for use in Android smartphones and is in the upper class in terms of performance. It supports all current mobile communication standards, including 5G SA. 

The CPU works with a total of eight cores, which are divided into two clusters. In the first cluster, an ARM Cortex-A78 power core clocked at 3.1 GHz is joined by three further ARM Cortex-A78 power cores clocked at 3 GHz. In the second cluster, four ARM Cortex-A55 power cores operate at 2.0 GHz. LPDDR5 RAM can be used as RAM and UFS 3.1 is supported as internal memory. 

In terms of connectivity, dual 5G with a theoretical peak download speed of up to 4.7 GBit/s is available, as well as WiFi 6E and Bluetooth 5.3.

The Mediatek Dimensity 8200-Ultra is a variant of the otherwise identical Mediatek Dimensity 8200 that has been specially customised for Xiaomi and features improvements to the camera ISP. An Imagiq 785 image processor is responsible for processing the camera data. Video recordings are supported with up to 4K at 60 fps. The CPU part of the older Dimensity 8100 is very similar and offers the same CPU and GPU cores.

The integrated ARM Mali-G610 MC6 graphics unit can power displays with a resolution of up to 2,960 x 1,440 pixels (WQHD+) and a refresh rate of up to 120 Hz. With Full HD+, even up to 180 Hz is possible.
