Rockchip showcases RK3528 TV box SoC and RK3562 tablet SoC

Rockchip showcased some new processors at Mobile World Congress 2023: the RK3528 for TV boxes, and the RK3562 for tablets both with a Cortex-A53 CPU subsystem, but the former comes with a Mali-450 GPU, and the latter with a faster Mali-G52 2EE GPU.

Both are clearly for entry-level devices, but I’m a little surprised they didn’t go with Cortex-A55 cores instead. Rockchip demonstrated the new processors in a TV box running Android 13 and a tablet with a 144,506 score in the latest Antutu benchmark as shown below.

Rockchip RK3528 preliminary specifications:

CPU – Arm Cortex-A53 processor (core count unspecified)
GPU – Arm Mali-450 GPU with AFBC compression support
Memory – LP4, LP4X, LP3, DDR4, DDR3
Video decoding – Up to 8Kp25
Supported OS – Android 13

Rockchip RK3562 preliminary specifications:

CPU – Quad-core Cortex-A53 processor @ 2 GHz
GPU – Mali-G52 EE
AI accelerator – 1 TOPS NPU
VPU – 4Kp30 video decoding, 1080p60 video encoding
Memory – 4GB RAM in tablet PC above
Storage – 32GB eMMC flash in tablet PC above
Camera – 1.3MP camera support

There’s no mention of OS support for the RK3562, but it would make sense to assume Android 13 since the RK3528 supports it. While the RK3562 was featured in a tablet PC, the tweet with the photo above refers to it as an “IoT” processor, so the range of I/Os may be greater than seen here.

The RK3528 is probably an upgrade to the RK3328 TV box SoC adding “8K” video decoding, and the RK3562 could potentially be a low-cost alternative to the RK3566 quad-core Cortex-A55 processor, although the EVB shown below makes it unlikely with features like HDMI and SATA not shown.

That evaluation board comes with a touchscreen display, two cameras, a few USB ports, a WiFi and Bluetooth module, a PCIe 2.0 slot, and a microSD card. I was also pointed to a Yocto Project repository with support for the RK3562-EVB. Neither the RK3528 nor the RK3562 processor are listed on the Rockchip website, so we’ll have to need to wait a little longer to find additional information.

Thanks to Geoffrey and Jasbir for the tips.
