8K TV box board features Amlogic S928X Cortex-A76/A55 SoC

The “YB910_428_V1.0” is an Amlogic S928X penta-core Cortex-A76/A55 board designed for 8K TV boxes with up to 8GB RAM, an HDMI 2.1a port, Gigabit Ethernet and WiFi connectivity, optical S/PDIF, a 3.5mm audio jack, and a few USB 3.2/2.0 ports.

We first started to see Amlogic S928X TV boxes from manufacturers such as SEI Robotics and SDMC last year, but those companies mostly cater to operators and I’ve yet to see any retail Amlogic S928X devices. The YB910 board could mean we are about to see some S928X devices for sale very soon.

YB910 board

Shenzhen Tomato simply copied the specifications from the processors, so I had to check the photos to derive the specifications. The company also says the board will run Android with a 4K GUI instead of the more usual 1920×1080 resolution, and based on previous announcements that should mean Android 13.

The Amlogic S928X processor is optimized for 8K TV boxes and we’re unlikely to see too many S928X SBCs as is the case for the more versatile (and expensive) Rockchip RK3588 processor. The Amlogic focuses on 8K video playback and output and comes with a single Cortex-A76 core and a Mali-G57 MC2 GPU that are fast enough to render user interfaces smoothly at 4K resolution.

Pricing is unknown, but a few more details about the YB910 8K TV box board can be found on Shenzhen Tomato’s website. Note that the company does not usually manufacture boards or devices themselves, and typically relies on other factories in China, but I was unable to find the actual manufacturer at this time.

No VVC?

Yes, I know it announced at last IBC
But I think all 8K board with last Mali chipset support VVC
8K need new codec (because profile restriction), so VVC and AV2

For troll, VVC (vs AV2 for 8K) like HEVC (vs AV1 for 4K) and AVC (vs VC1 for HD) will be a good/best codec for new format resolution
