MediaTek Dimensity 800U

Enabling the Most Essential 5G Technologies

The Dimensity 800U provides 5G-CA (2CC 5G Carrier Aggregation) and Dual 5G SIM; technologies offered beyond competitor solutions.

5G Technologies

Dual 5G SIM

MediaTek leads yet again in Dual SIM technologies, building on our history of being first-to-market we’re first again with dual 5G SIM. The Dimensity 800U provides this essential feature to the widest user-base yet.

Dual 5G SIM gives you 5G that’s always on. It means dual standby (DSDS) readiness and access to true 5G speeds from both connections, plus 5G-exclusive VoNR services from either connection. VoNR is much faster establishing the call and provides the best ever voice and video quality while on the call.

5G-CA Improves Coverage & Effective Performance

5G-CA enables higher average speeds and a seamless handover between two 5G connection areas across a coverage layer, where users receive over 30% greater throughput layer coverage than without CA.

The World’s Most Power-Efficient Smartphone 5G Modem Design

MediaTek 5G UltraSave enhances the 5G modem with even more power-saving technologies:

  • MediaTek 5G UltraSave Network Environment Detection
  • MediaTek 5G UltraSave OTA Content Awareness
  • Dynamic BWP
  • C-DRX (Connected Mode DRX)

Boosted Big Cores That Get You In The Game Faster

Featuring two Arm Cortex-A76 ‘Big’ cores operating up to a speedy 2.4GHz in its octa-core CPU, the Dimensity 800U provides a powerful peak performance that means ultra-responsive action in everything you do.

These fast CPUs are partnered with a high performance Arm Mali G57-class GPU, extreme clocked LPDDR4X memory up to 2,133MHz and next-gen UFS 2.2-class storage to give the best all-round smartphone experience, whether you’re streaming video, snapping pics, chatting with friends or working on the go.

In top titles, game launch times are up to 1.4s faster than Dimensity 700 series, while benchmark scores are up to 11% faster in CPU and 28% faster in GPU performance.

Blur-busting 120Hz Displays

120Hz displays provide a supreme user experience, whether it’s for experiencing the fastest response in games with zero-blur, or the benefit of notably smoother scrolling of webpages and animations in apps. Using the Dimensity 800U, brands can offer smartphones with crisp, high resolution FullHD+ displays and ultra-fast responsiveness.

MiraVision Enhanced HDR Video Playback & Displays

MiraVision enhances HDR10+ content playback with MediaTek ‘local tone mapping’ technologies by retaining more detail and contrast even through the extremes of light and dark regions. MiraVision can even upgrade standard HDR10 video to approach HDR10+ quality in real-time, by creating dynamic metadata on-the-fly to enable per-frame luminance optimization without overexposure.

Since all smartphone displays are different, MiraVision is intelligent and flexible, assessing the display capabilities of each device and optimizing accordingly via a unique re-mapping technology.

Up to 64MP Cameras

Brands can embrace larger cameras than competitive chips, enabling up to 64MP main sensors, plus a framework to embrace up to four cameras in their smartphone designs; enabling a variety of enticing smartphone options to meet market needs. In-built imaging accelerators, such as a high-performance hardware depth engine for accurate bokeh in real-time previews and pictures, anti-distortion-warping, noise reduction and facial detection that work together to enhance the photography and video capture results.

The integrated MediaTek NPU allows brands to provide customized software and AI-camera enhancements for unique differentiation in live or post-effects, or security features like facial or person recognition.

Integral, Multiple Voice Assistants

A variety of virtual assistants support our daily lives in different ways. The Dimensity 800U can listen for multiple trigger words to wake up virtual assistants such as Google Assistant, Amazon Alexa or other localized services.

Fully integrated into its design, brands get a power and size optimized system with integral noise suppression that’s easy to use and offers the greater consumer choice.
