ROCK64 is a credit-card size 4K60P HDR Media Board Computer powered by Rockchip RK3328 Quad-Core ARM Cortex A53 64-Bit Processor and supports up to 4GB 1866MHz LPDDR3 memory. It provides an eMMC module socket, MicroSD Card slot, Pi-2 Bus, Pi-P5+ Bus, USB 3.0, and many other peripheral interfaces for makers to integrate with sensors and other devices. Many different Operating Systems (OS) are freely available from the open source community, such as Android 7.1, Debian, and Yocto.

ROCK64 Software Images

Under ROCK64 Software Release you will find a complete list of currently supported Operating System images that work with the ROCK64 as well as other related software.

The list includes OS images and descriptions of:

Quick Links to the Source of OS Images Build

Some OS images are still in beta or nightly build which are only fit for testing purposes. These should usually be avoided for normal usage, since they are used at your own risk

State of Software Support for the Hardware

Requirement GNU/Linux Android/Linux Kodi/Linux
2160p 30Hz 8bit h264/h265/vp8 partial? 1 yes yes

Upstreaming Status

Function Status Component Notes
Video Output Linux Mainline rockchipdrm With mpv, you'll need to specify something like mpv --gpu-context=drm --drm-connector=1.HDMI-A-1 to get it to play back on a VT
3D Acceleration Linux Mainline Upstream Mesa lima Very recent version recommended for the best experience
Video Decode Linux Mainline Not in ffmpeg hantro_vpu and rockchip_vdec, using v4l2m2m Moved out of staging in 5.13, ffmpeg patch set seemingly abandoned as no response was made to a patch review in several months. Git branch with commits
Audio Linux Mainline snd_soc_rockchip_*
Power Button Linux Mainline rk805_pwrkey If your PWR switch does nothing unless held, this may need to be loaded manually with modprobe or by putting it in /etc/modules-load.d/

SoC and Memory Specification

  • Based on Rockchip RK3328

CPU Architecture

  • Quad-core Cortex-A53 up to 1.5GHz CPU
  • Full implementation of the ARM architecture v8-A instruction set
  • ARM Neon Advanced SIMD (single instruction, multiple data) support for accelerated media and signal processing computation
  • ARMv8 Cryptography Extensions
  • In-order pipeline with symmetric dual-issue of most instructions
  • Unified system L2 cache
  • Includes VFP v3 hardware to support single and double-precision operations
  • Integrated 32KB L1 instruction cache, 32KB 4-way set associative L1 data cache
  • TrustZone technology support
  • Full CoreSight debug solution
  • One separate power domain for CPU core system to support internal power switch, and to externally turn on/off based on different application scenario
  • PD_A53: Cortex-A53 + Neon + FPU + L1 I/D Cache of core 2/3
  • One isolated voltage domain to support DVFS

Frequencies & Voltages

Frequency Voltage
408 MHz 0.950 V
600 MHz 0.950 V
816 MHz 1.000 V
1008 MHz 1.100 V
1200 MHz 1.225 V
1296 MHz 1.300 V

Power Draw

These numbers for power draw have been measured through an USB power monitor (FNB38) while running the stress utility, whereby "cpu" stands for stress --cpu 4 and "vm" stands for stress --vm 4. The former spins on the CPU, the latter stresses the memory. Real workloads are usually a mix of both. The tests were ran through ssh, with nothing besides power and ethernet plugged into the ROCK64

Please keep in mind that under real world usage, many other factors come into play. Having a display connected, running a graphical session, I/O and most importantly the connected USB peripherals can add a lot.

Helpful refresher on the formula for power (W) on DC: power = current × voltage, because the power factor is 1. The ROCK64 runs on 5V, so use that to calculate current if you need to.

Frequency Power cpu Power vm
1296 MHz 2.64 W 2.95 W
1200 MHz 2.32 W 2.69 W
1008 MHz 1.90 W 2.31 W
816 MHz 1.62 W 2.05 W
600 MHz 1.45 W 1.85 W
408 MHz 1.33 W 1.72 W
Idle (no load) 1.10 W

It appears a good upper bound for a headless setup is in the neighbourhood of 3 W, or the energy contained in 0.025 bananas per hour.
