MediaTek Helio G91

The MediaTek Helio G91 provides great everyday performance, smooth 90Hz displays and impressive 108MP cameras with in-sensor zoom.

Impressive 108MP Camera

Using impressive 108MP cameras elevates 4G smartphones with finer details in daylight and clear night shots. In-sensor zoom with 2.0um pixel binning enables clearer night shots and lossless portraits with finer details.

Building on generations of photographic excellence in multi-camera smartphones, the G91 includes a multitude of hardware accelerators, including a hardware depth engine for dual camera bokeh captures, Camera Control Unit (CCU), Electronic Image Stabilization (EIS), and Rolling Shutter Compensation (RSC) technologies.

MediaTek HyperEngine Gaming Technologies

Intelligent Resource Management Engine

  • Intelligent, dynamic management of CPU, GPU and memory according to active measurements of power, thermal and gameplay factors to ensure sustained performance and smoother gameplay that lasts longer, even in heavy-loading game engines, demanding scenes and intense gameplay.
  • High FPS power savings combine hardware and software enhancements to reduce the power consumption during high FPS gaming scenes, extending battery life without sacrificing the user experience.

Networking Engine

  • Call & data concurrency allows users to defer calls while in-game without the data connection dropping.
  • Intelligent prediction of Wi-Fi & LTE concurrency triggers in just 13 milliseconds
  • Wi-Fi antenna swapping can dynamically adjust the signal between inbuilt antennas to optimize the connection for lower latency and higher data throughput.

Dual 4G VoLTE

Benefit from exceptional voice and video call quality, faster connection setup time, more reliable coverage and lower power consumption in voice and video calls than traditional phone lines.

Ideal Driving Partner

An inertial navigation engine that understands its dashboard mount orientation, it provides an accurate location when underground, driving through tunnels and in any other situations where GNSS services are unavailable.

Inbuilt voice wakeup (VoW) capability allows smartphone designers to easily add helpful voice assistant services for hands-free responses when driving.
