Upcoming RTD1619 Media Players – Dune HD Pro 4K II, Zidoo Z9X, and Zidoo X

Realtek RTD1619 hexa-core Cortex-A55 media SoC was first spotted in 2018 in the Linux source code. Since no products had been launched based on RTD1619, I had mostly forgotten about the processor until I wrote about RTD1395 powered Dune HD RealBox 4K.

I was then informed about the upcoming Dune HD Pro 4K II, and a quick search reveals Zidoo is also working on its own RTD1619 media players with Zidoo Z9X and Zidoo X models.

RTD1619 TV Box Media Center

Zidoo Z9X runs Android 9.0 and OpenWrt OS simultaneously just like in the company’s Zidoo X9S TV box where Android manages apps and multimedia functions, and OpenWrt Linux handles the NAS functions.

The device was announced on Zidoo forum without photos, and instead, I found some on the FCC website. It’s unclear when Zidoo Z9X will launch and at what price but it should be fairly cheaper than the Dune HD device.

Zidoo X targets videophiles and audiophiles, and there were rumors of a $1,000+ price tag following a price listed on a reseller’s website, but it’s been since removed, so we’ll have to wait a bit longer for the price. Zidoo X was announced on Zidoo forum last year, and in some more recent comments, one person expects the launch in October 2020.

Thanks to Andreas for the tip.

    Stock: Pre-order. Despatch: Fri 17-Jul. ?

    1. Zidoo replied to my email:
      <blockquote>Z9X will be available about end of July</blockquote>

  2. 6-core Cortex-A55 seems interesting.
    But I would skip everything until AV1 hardware decode is available.
