Rockchip Android TV Boxes Promotion Starting at $13.99 (US Only)

May 16th, 2017 1 comment

GearBest is organizing a promotion for its US warehouse, and there are three good deals for  TV boxes, especially with Rockchip RK3229 based SCISHION V88 going for $13.99 (limited to 30 units). Make sure you only buy one, as usually, the company will cancel orders with more than one piece for this type of promotion.

If the 1GB RAM in V88 is too little for you, you may consider V88 Plus model with 2GB selling for $17.99, or Dolamee D5. There’s also a $10 discount$10 discount on Yundoo Y8 RK3399 TV Box. They also have some other discounts for 3D Printers, and drones/rc toys. All you need is a physical address in the US.

Yundoo Y8 Rockchip RK3399 TV Box System Info and Benchmarks

April 24th, 2017 6 comments

Most 64-bit ARM processors found in TV boxes and mini PC features ARM Cortex A53 cores which are good enough to watch most videos, since video decoding is usually handled by the video processing unit. But if you want some more performance for games and web browsing, SoCs based on Cortex A72 or similar high performance ARMv8 cores would deliver much a much better experience in Android. The problem is that there aren’t many options with products such as NVIDIA Shield Android TV, and Xiaomi Mi Box 3 Enhanced. The former is potentially expensive depending where you live, and the later is targeted at the Chinese market and lacks an Ethernet port. Rockchip RK3399 SoC should fill the market void for people wanting to do more than just watching videos on their TV box, and since I’ve just received Yundoo Y8 TV box based on the processor, I’ve run some apps to check out system information, and benchmark the system.

Yundoo Y8 / Rockchip RK3399 System Info with CPU-Z

CPU-Z appears to have improved since it can now detect clusters, and could detect a processor with two clusters: 2x Cortex A72 @ up to 1.99 GHz and4x Cortex A53 @ up to 1.51 GHz, as well as a Mali-T860 (actually T860MP4).

Yundoo Y8 runs Android 6.0.1 on top of Linux 4.4.16, but I’ve read that other upcoming models based on RK3399 will run Android 7.1 instead.

Yundoo Y8 / Rockchip RK3399 Benchmarks

Let’s start with Antutu 6.x.

The 76,819 points achieved by the device is a big improvement compared to – for example – the 41,000 points in Amlogic S912 TV boxes. It also beats the ~71,000 points of Xiaomi Mi Box 3 Enhanced also based on a hexa-core Cortex A72/A53 processor (Mediatek MT8693), but at a lower 1.57 GHz maximal frequency, with a PowerVR GX6250 GPU,. and running Android 5.1 instead of Android 6.0.

Vellamo 2.x confirms the good performance of Rockchip RK3399: 5,275 points for Chrome Browser test, 2,492 points for Multicore test, and 2,332 points the Metal test. Amlogic S912 TV boxes gets about half that, and it’s also significantly better than Mi Box 3 Enhanced except for the metal test (2,392 points).

The most powerful mobile/embedded GPUs will easily max out in 3Dmark Ice Storm Extreme 1.2 test, but the Mali-T860MP4 in RK3399 cannot quite do it, although with 9,906 points it’s a big improvement over the Mali-T820MP3 found in Amlogic S912 (~5,750 points), and slightly better than PowerVR GX6250 GPU in Mediatek MT8693 (9,260 points) using 1920×1080 output resolution.

Since low power processors are gone a long way in recent, I wanted to check out far it was from my main computer based on AMD FX8350 processor (125 Watt TDP) and running Ubuntu 16.04. One way to compare performance across different hardware and operating systems is to run GeekBench cross-platform benchmark.

GeekBench 4 Android Results for Yundoo Y8:

The single Cortex A72 core performance is about 50% of an FX8350 “Piledriver” core. Not too bad, even though the single core performance of this AMD CPU is not the best in the world. Multi-core performance is another story, as there are less cores/threads (6 vs 8), my computer throttles when all 8 cores are used (Normal score should be 10,000 to 12,000) , and it appears the Cortex A53 cores in RK3399 may not be used at all in GeekBench’s multi-core test. For reference, the latest Samsung Exynos 9 (8850) gets respectively 1,978 and 6,375 points in the same benchmarks. I’m assuming than in 4 to 5 years, we should be able to get AMD FX8350 type of performance in a mobile device.

Ethernet performance should be about the same in all RK3399 devices, and I tested with iperf with the command used in the TV box shown in brackets:

  • Full duplex (iperf -t 60 -c 192.168.0.104 -d):

  • Upload only (iperf -t 60 -c 192.168.104):

  • Download only (iperf -s):

So it’s working pretty well here.

Internal storage will different from box to box, and even Yundoo Y8 with 32GB storage should perform than the same box with 16GB storage, but USB 3.0 performance should remain pretty much the same across devices.

The cached read is for the internal memory (eMMC flash) which we’ll ignore here due to reason explained above. The “SD card” is the NTFS partition of my Seagate USB 3.0 drive, and results are pretty good with 94.34 MB/s sequential read, and 53.50 MB/s sequential write considering I could achieve 107 MB/s and 45 MB/s with that hard drive in my main computer.  The RAM test shows a 9684.47MB/s copy, which compared to the 3301.73 MB/s achieved by Mecool BB2 Pro Amlogic S912 TV box with DDR4 memory.

So overall the platform looks promising, and offers a significant performance boost compared to the Cortex A53 competition at an affordable price, more exactly $90 and up with 2GB RAM, 16GB storage. The downside is that since the SoC is rather new there may be a few firmware bugs at this stage, which I’ll check/report in the full review, but I’m confident they will be ironed out over time, if not in Yundoo Y8, in other RK3399 devices.

Yundoo Y8 (Rockchip RK3399) TV Box Review – Part 1: Unboxing and Teardown

April 21st, 2017 17 comments

Rockchip first unveiled RK3399 hexa-core processor at the beginning of 2016, but we had to wait longer than expected to get devices to play with. The first retail product based on the processor is really Samsung Chromebook Plus, and we only saw a few TV boxes for pre-sale in January such as Yundoo Y8 or R-TV Box K99, and with the first shipments occurring in March. However, I’ve also noticed many companies postponed the launch of the RK3399 mini PC/TV box, and no company contacted me for review so far, so I had no rush because that probably means the boxes were not quite ready. But starting at the beginning of next month, more companies will start selling their model, and GearBest proposed to send me Yundoo Y8 model with 4GB RAm, 32GB flash, and decided to give it a go. In this first part of the review, I’ll only look at the hardware, and will further test overall performance, video & audio capabilities, in subsequent posts.

Yundoo Y8 Unboxing

The retail package refers to Yundoo Y8 “True 4K” media player.

There are two version for Y8 model one with 2GB RAM, 16GB storage, and the other with 4GB RAM/32GB storage which I received,

The box ships with a HDMI cable, an infrared remote control with IR learning function for 5 keys, a 5V/2.5A power supply, and a rather useless user manual.


The enclosure is made of plastic with the power button on the front panel, an SD card, USB 3.0 port, and USB type C port on one of the side, with the rest of the ports on the rear panel: DC jack, optical S/PDIF, AV port (composite + stereo audio), Gigabit Ethernet, HDMI 2.0, and two USB 2.0 ports.

You may watch the unboxing video if you please.

Yundoo Y8 Teardown

We’ll start our unboxing by removing 3 rubber pads from the bottom of the case, and loosen the three screws underneath. You can leave the one at the top left alone, since there’s nothing there.

The gap between the two side of the enclosure is extremely small, and my green plastic tool was not sharp enough, so I took a bit more risks and used a sharper metal tool to get started with popping up the bottom part of the case, before carrying on with the plastic tool.

There’s no much to see on the bottom of the board, except a footprint for a wireless module with one antenna, and the sticker showing the key features of the board: RK3399, 4G/32G, and AP6356 wireless module. After removing four more screws, we can completely take the board out.

A large heatsink covers the processor and RAM chips, and it’s further cooled by a thermal pad and a thick metal plate attached to the box of the case. Two antennas are connected to the Wireless module, which could help with WiFi reliability and/or performance. The power button and LED is located in a separate small board.


I’ve removed the heatsink to have a better look at the board, Note that there’s no thermal paste between the heatsink and the processor, but instead the company used another thermal pad.

Rockchip RK3399 processor is connected to four Samsung K4B8G1646D-MYK0 DDR3L chip (4x 1GByte), and a 32GB Samsung KLMBG4WEBD-B031 eMMC 5.0 flash with theoretical 260/46 MB/s sequential read and write speed, and 6000/5000 R/W IOPS, which should offer a good user experience. That’s still the lowest end 32GB Samsung eMMC flash there is. Ampak AP6356S module brings dual band 802.11 b/g/n/ac 2×2 (Up to 867 Mbps) and Bluetooth 4.1 LE connectivity to the board, while Gigabit Ethernet is made possible thanks to ZTE ZX2AA500 transceiver – no a Realtek chip for once – and SG24002 magnetics. Rockchip RK808-D PMIC completes the list of the mains chips on the board. You may have also noticed the unpopulated 4-pin header  on the bottom right of the board which should be the serial console. The firmware recovery button is hidden right behind the AV port.

I’d like to thank GearBest for sending a sample for review. If you are interested you could purchase the device on their website for $109.99 with coupon GBYDY8, or $90 with coupon GBYDY816 for the 2GB/16GB version. Yundoo Y8 appears to be a GearBest exclusivity, as I failed to find it on Aliexpress, GeekBuying and other websites.
