Rockchip RK3568 processor to power edge computing and NVR applications

We recently reported on the Rockchip developer conference (RKDC) 2020, and especially the upcoming Rockchip RK3588 Cortex-A76/A55 processor that packs a lot of power and features, and is now scheduled to launch in Q3 2021.

But as you can imagine there were other products revealed during the conference, including the new Rockchip RK3568, similar to the previously announced RK3566, and designed for edge computing and network video recorder (NVR) applications.

RK3568, RV1106, RK353X, RV1128There’s also an RK353X processor specifically designed for NVR application that should have similar performance as RK3568, but a lower cost, as well as two UP camera SoC with RV1106 and RV1128.

CNX Software managed to obtain the presentation for the RK3568 processor from the conference so we’ll focus on the quad-core Cortex-A55 processor in this post.

Rockchip will provide Android and Linux BSPs for the AIOT processor, and the AI accelerator will support Caffe, TensorFlow, TF-Lite, ONNX, PyTorch, etc.. through the RKNN Toolkit already used by Rockchip RK1808 and RK3399Pro.

RK3568 is extremely versatile and Rockchip expects it to be found in NVRs, cloud terminals, IoT gateways and industrial control applications, car infotainment systems and dashboards, and even Karaoke machines.

I was also informed that RK3566 specifications had changed a bit since the last announcement/leak in February, and now closely match RK3568 specifications except for the lack of PCIe 3.0 interface, and a smaller number of IOs. Both RK3568 and RK3566 are sampling now, and are sold as mid-range parts as shown in the Rockchip IoT SoC roadmap below which also reveals the new entry-level RK3358 quad-core Cortex-A35 processing coming soon.

Those who follow RK3588 leaks history may remember the processor was first unveiled with an Arm “Natt” GPU, and in our recent story update, it got an upgrade to an Arm “Odin” GPU. Those are yet to be released Arm Mali “Vaxhall” GPUs, but a slide in the presentation show Natt is the successor of the mid-range Mali-G52, while “Odin” GPU are parts of the high-performance GPU such as Mali-G72…
