Performance & Benchmarks
The FireFly board RK3399 SoC is equipped with six cores (Hexa). This Hardware platform integrates a Dual-core ARM Cortex-A72 MPCore processor operating with a max clock frequency of up to 1.9 GHz and a Quad-core ARM Cortex-A53 MPCore processor running at a max frequency of up to 1.5 GHz. In a minimal workload (idle) mode, each of the processor cores operates at frequencies of 480MHz and dynamically changes frequency according to system resources.
In video and graphics, this board has a very speedy Mali-T860MP4 capable of decoding videos and rendering graphics very fast. That said, the AnTutu score ranked 76458, considered a top score for any development board. This means the hardware is strong enough to be used as a Mini PC or workstation running Android 6.0.1 / Ubuntu OS. Compared to Unuiga T96 PRO (3GB / 32GB) Android Set-top Box hardware based on Amlogic S912 SoC and equipped with a Mali 820MP3, the Firefly hardware performed ~56% better. The additional GPU Core and 1GB of RAM greatly impacted system performance, especially when running “heavy” graphics and games on this top-notch hardware.

KODI Support
Another significant advantage for KODI fans is the excellent combination of the powerful Mali-T860MP4 (4 Cores) GPU with HDMI Ver 2.0 interface. According to Wikipedia, the new RK3399 SoC supports video hardware acceleration.
From my impression, the GPU performed exceptionally well-decoding video files under Android 6.0 64-Bit OS. In most cases, the average home user will probably not have such a high resolution and frame rate. Still, it’s important to mention that after installing and testing the latest Kodi v17 (Krypton) 64-Bit APK package, I could also play video files sampled at 4K@60fps. They played very smoothly, without any noticeable video lags.
Operating Systems, Software Support
T-Chip Company provides two types of Images based on 64-bit ARM Architecture. Android 6.0 and Ubuntu 16.04 run under an Xfce desktop environment that is dual boot supported. What lets you switch between OS in a matter of a few seconds? If you want to experience more OS, you are limited as a user. More OS images could be likable, for example, LibreELEC, Debian Linux, Armbian, Phoenix OS, Remix OS, etc.
T-Chip provides good documentation and support in its website support section. They also include Android 6.0.1 SDK Source for software developers interested in coding under the Rockchip RK3399 hardware platform.
In terms of user experience, both OS performed very smoothly and fast as you would operate a Mini Desktop PC. Because the company is currently focused mainly on China and Google services are blocked in China, the Android 6.0 image was missing Google Play store support, something I needed, and hopefully, it will be added in future Android photos.

Other special features
Dual Mode Display
Focusing on a few main highlights this board has to offer. The Board integrates about four types of external video interfaces. Among them is a USB 3.0 Type C interface that functions as an OTG-type interface that supports DP 1.2 standard and can be used to output a video signal in 2Kx4K Quality. Both HDMI and USB 3.0 Type C and the HDMI 2.0 interface are capable of working simultaneously under Android 6.0 OS in this Dual Display Mode. You need to make it work to buy a USB 3.0 Type C HDMI adapter or cable and just connect it to another monitor.

Optional Accessories (Not included in Kit)
4G LTE module board
Another convenient feature is the option to add a 4G LTE module board that costs $75, which connects to the board PCIe interface. Then you can use a SIM Card to connect to the internet via a local cellular service provider. With this module, you can use the Firefly board as a router to share a connection across other WIFI devices, making it a fully independent portable device with 3G/4G connectivity.
Kit Content:
- x1 4G LTE Module
- x1 5db Antenna
- x1 Antenna Cable
- x4 M2 Screw
- x2 Nut stud
SATA3.0 Interface
To connect with an external hard drive, you will need to buy the PCIe M.2 to SATA3.0 Adapter Board/module, which is pretty cheap and cost about $9.0. The module provides two SATA 3.0 Ports with two 5V power connectors that should be enough to connect and power two SSD drives.

- 1x PCIe M.2 (B-KEY) to SATA 3.0 Adapter Board
- 1x Screw Stud
- 2x M2 Screw
IR Remote
For users that want to use the Firefly as a Mini PC and want to turn it remotely, without pressing the Onboard power button all the time to turn the unit on and off, you can purchase a simple IR remote for a price of $5.
Power Consumption
The Firefly RK3399 board consumption was low and not extraordinary considering this board is a high-level performance SoC with 6 Processor Cores. Using a power meter device connected to a power socket, consumption was measured between 9.0 – 13 W when playing 4K videos with KODI Media Player 17.1 Krypton. In Idle mode, “lite” usage with some browsing power was between 6.0-7.1 W.
Keep in mind that these results are not absolute. This means they change dynamically according to usage and consume system resources. If all cores of the processor cores are active and additional external devices are also hooked up to the board, results will change accordingly. In this specific test, I connected Wireless Keyboard, Wirelesses Mouse, and an external USB Hard drive where the video samples were stored.
Firefly RK3399 Power Consumption 4.3 W | idle Mode
CPU Temperature
The Firefly RK339 kit comes with a semi-open case composed of a base and upper plastic plates opened from all sides so the extra heat can get out quickly. With Firefly’s excellent Heatsink, the processor core temperature measured between 25-26C. If I used a closed case, the results were probably much higher.
Final Words
All items included in the package were top quality. This Board is considered top-level hardware with superb performance, capable of running apps and games, including KODI. With all the advanced onboard interfaces, software developers have plenty of features to play with and experiment with. The Firefly-RK3399 Plus Kit I reviewed cost $219. For people that feel this price is too expensive, There is also a low-cost, basic version with 2GB RAM / 16GB EMMC on sale for $ 179.
