MediaTek has launched a tweaked version of its eight core system on chip with a AI inference block for dual SIM 5G phones.  

The Dimensity 800U is built on TSMC’s 7nm process and supports 5G+5G dual SIM dual standby (DSDS), dual Voice over New Radio (VoNR), and 5G two carrier aggregation (2CC 5G-CA). The chip adds dual SIM capability with a small boost in clock speed and screen refresh rate over the Dimensity 720 launched last month.

The SoC has an octa-core CPU with a dual cluster consisting of two Arm Cortex-A76 processors with a clock speed of 2.4GHz and six Arm Cortex-A55 processors with a clock speed of 2.0GHz. Alongside these are an Arm Mali-G57 GPU, an independent AI processing unit (APU) and LPDDR4x RAM. It supports a 120Hz display with the HDR10+ standard.

The chip supports flexible camera placement with up to four 64MP cameras with the APU and an image stabilising processor for image enhancement.

It also includes support for voice on wakeup (VoW) and dual-mic noise reduction technology, lowering the standby power consumption of a voice assistant, and enabling it to hear clear sound regardless of external noise interruptions.

“MediaTek has always focused on enhancing the user experience with our leading semiconductor technology, whether consumers are streaming, gaming or taking photos,” said Dr. Yenchi Lee, Deputy General Manager of MediaTek’s Wireless Communications Business Unit. “MediaTek’s Dimensity 800U brings cutting-edge, next-gen technology to the Dimensity SoC series, bringing MediaTek’s advanced 5G, imaging and multimedia technologies to high-performance 5G smartphones.”
