MediaTek’s MT9638 supports multiple advanced technologies:

  • Up to 1.5GHz  multi-core ARM Cortex-A55 CPU, Arm Mali-G52 MC1 GPU and dedicated MediaTek APU
  • Up to 4K60 resolution support with a multimedia decoding engine for HEVC, VP9 and the latest AV1 content.
  • HDR10+ display support, enabling full array backlight local dimming with up to 2304 backlight dimming zones
  • Dolby Atmos and DTS Virtual X surround sound support.
  • HDMI 2.1a and USB 3.0 interfaces, in addition to gigabit-class Wi-Fi 6 connectivity.
  • Up to four far-field microphones offer whole room coverage for voice assistants with ultra-low power consumption (0.5W) on standby and ultra-fast, one second resume for wake-up words.

MediaTek MT9638-powered 4K smart TVs are expected to roll out in Q2 2021.

Commenting on the new chip, Alex Chen, General Manager of the TV Business Unit at MediaTek, said:
