MediaTek continues its quest to create affordable 5G smartphones; The latest step in that direction is the Dimensity 700, a 7nm chipset similar to the recently announced Dimensity 720.
The most important component is the 5G modem. Supports carrier aggregation enabling faster connections (downlink speeds up to 2.77 Gbps) and smooth 5G inter-cell handoff. The modem also includes Dual SIM, Dual Standby and VoNR (“Voice over New Radio” offers better audio quality than previous generations).
The modem also features global 5G NR band support and MediaTek “5G UltraSave” power saving technology.
The Dimensity 700 CPU is made up of two Cortex-A76 cores running at 2.2 GHz (slightly faster than the large 720 CPU) and six Cortex-A55 cores running at 2.0 GHz. The chip can be connected to up to 12GB LPDDR4x RAM (2133MHz) and UFS 2.2 dual-lane storage (transfer rates up to 1GB / s).
The new chip can handle 1080p + displays with a 90Hz refresh rate, although its GPU is an ARM Mali-G57 MC2, down from the G57 MC3 found within the 720. See the table below for further comparison detailed between the two chipsets.
| Dimensity 700 | Dimensity 720 | |
| Process | 7 nm | 7 nm |
| CPU (large cores) | 2x Cortex-A76 at 2.2 GHz | 2x Cortex-A76 2.0 GHz |
| CPU (small cores) | 6x Cortex-A55 2.0 GHz | 6x Cortex-A55 2.0 GHz |
| GPU | Mali G57 MC2 (950 MHz) | Mali G57 MC3 |
| RAM | Up to 12GB, LPDDR4x 2133 MHz | Up to 12GB, LPDDR4x 2133 MHz |
| Storage | UFS 2.2 (2 lanes, up to 1GB / s) | UFS 2.2 |
| Monitor | 1080p +, 90 Hz | 1080p +, 90 Hz |
| Modem | 5G, dual SIM, 2.77 Gbps | 5G, dual SIM, 2.77 Gbps |
| Connectivity | Wi-Fi 5, Bluetooth 5.1 | Wi-Fi 5, Bluetooth 5.1 |
| Camera | 64 MP, 1080p still images at 30 fps | 64 MP still images, 4K at 30 fps |
The Dimensity 700 is limited to 1080p resolution for video capture, while the 720 goes up to 4K, making it more suitable for the mid-ranges. For photos, the new chip can handle cameras up to 64MP and features multi-frame noise reduction and various AI enhancements.
Speaking of AI, various voice assistants can run on the chip, including those from Google, Amazon, Alibaba, Baidu, and Tencent.
MediaTek also added two chipsets intended for Chromebooks to its stable, the MT8195 and MT8192. The MT8195 is the most advanced option, made with TSMC’s 6nm process and with four of the latest Cortex-A78 cores in addition to four A55 cores.
There is also a 5-core Mali-G57 and 4-TOPS capable APU, which can be used for speech and image recognition (including ultra-low power voice activation). Dolby Vision, 7.1 surround sound, and AV1 decoding are supported.
The MT8192 builds on the older 7nm process and uses four A76 cores, which are now two generations. The APU is also slower, with a 2.4 TOPS rating. The GPU is the same, a 5-core Mali-G57, which can handle 1440p 60Hz displays or 1080p 120Hz display. Both chips feature PCIe Gen 3 and UBS 3.2 Gen 1 connectivity.
Chromebooks using the new chips will go on sale in the second quarter of 2021.
