MediaTek Helio G99

The MediaTek Helio G99 brings 4G gaming smartphones into the next generation. Built on the highly efficient TSMC N6 (6nm-class) chip production process, this chip enables great gaming all day, plus big cameras, fast displays, smooth streaming, and reliable global connectivity. Partners can tailor MediaTek Helio G99 platform to meet specific requirements for their devices or markets.

Exceptional Power Efficiency

We’ve upgraded the Helio 4G series, with the G99 using TSMC N6 (6nm-class) chip production process, enabling it to be exceptionally power efficient and giving device makers new opportunities to create gaming smartphones that last longer than ever.

Super-fast 120Hz Displays with Intelligent Display Sync

Device makers can create slim and light gaming smartphones with crisp, high resolution Full HD+ 120Hz displays, without needing extra DSC hardware. Now a demanded feature even for 4G smartphones, 120Hz displays provide a supremely smooth everyday experience, with notably smoother scrolling of webpages and animations in apps.

MediaTek Intelligent Display Sync technology improves the power efficiency of these fast displays by dynamically adjusting the refresh rate to only enable faster speeds when it’s needed most.

108MP Main Camera

Device makers can adopt big 108MP cameras, allowing users to capture the most detailed photos. Dimensity-class image quality technologies provide superior photography results compared to other MediaTek Helio series chipsets. Dual cameras up to 16MP with ZSL gives highly detailed bokeh captures in dual selfie and multi-camera designs.

Superb Performance

The MediaTek Helio G99 features an octa-core CPU with two high performance Arm Cortex-A76 processors clocking up to 2.2GHz and a highly capable Arm Mali G57-class GPU. High performance LPDDR4X memory up to 2,133MHz and fast UFS 2.2-class storage accelerate data access, maximizing performance in games, apps and everyday activities.

MediaTek HyperEngine 2.0 Lite gaming technologies

Resource Management Engine 2.0

An Intelligent Resource Management Engine ensures sustained performance and smoother gameplay that lasts longer.

  • Intelligent, dynamic management of CPU, GPU and memory according to active measurements of power, thermal and gameplay factors.
  • Smoother performance 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 2.0

The Networking Engine gives faster response and more reliable connectivity to ensure you always stay connected.

  • Call & Data Concurrency allows users to defer calls while in-game without the data connection dropping
  • Wi-Fi antenna swapping that can adjust the signal between antennas to optimize the connection for lower latency and higher data throughput

Dual 4G VoLTE

The fast Cat-13 4G LTE modem is integrated into the chip for best power efficiency. Global bands and IMS services are supported, while advanced features such as 4x4 MIMO and 256QAM provide reliable connectivity even in areas of high network traffic.

Essential dual 4G SIM provides a seamless experience with fast data services from both connections, while VoLTE and ViLTE services provide excellent call and live video experiences with faster call setup and noticeably better quality than standard calling.
