MediaTek Dimensity 1080 vs MediaTek MT8188J vs MediaTek Dimensity 900

MediaTek Dimensity 1080

The Mediatek Dimensity 1080 is a mid-range ARM SoC (system-on-a-chip) that can be used in both smartphones and tablets (mainly Android). The SoC integrates two ARM Cortex-A78 cores with up to 2.6 GHz for demanding tasks and six power-saving ARM Cortex-A55 cores with clock rates of up to 2 GHz.

The chip has an integrated sub-6 GHz 5G modem including dual-SIM support that can reach a maximum download speed of up to 2.77 Gbit/s. Wi-Fi 6 (802.11ax) is supported as well as Bluetooth 5.2.;

The memory controller copes with LPDDR4x or LPDDR5 working memory as well as UFS 3.1 mass storage. As an integrated graphics card, the SoC uses the ARM Mali-G68 MC4, which supports displays with 120 Hz as well as HDR10+ at a maximum resolution of 2,520 x 1,440 pixels.

The differences to the Dimensity 920 are minor, only the slightly higher maximum clock and a support for higher-resolution cameras can be found.

The MediaTek Dimensity 1080 is still manufactured in 6 nm.

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 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.
