iFive and Techvision Rockchip RK3399 Hybrid Tablet/Laptop to Run Android 6.0 or Remix OS 3.0

October 16th, 2016 14 comments

We’ve seen Samsung is about to release the first Rockchip RK3399 Chromebook to the market. However it will be selling for $499, possibly a bit more than many people are ready to pay for such device, so Rockchip RK3399 powered iFive and Techvision 2-in-1 hybrid laptop & tablet devices showcased at the Hong Kong Electronics Fair might be worth a look as they should be quite cheaper.

The solution from Techvision ODM design house is a proper 2-in-1 hybrid laptop with a 11.6″ detachable screen with 1920×1080 resolution, two USB ports, a USB Type-C port and HDMI 2.0 output. The laptop also includes 2GB RAM, and 16GB flash. iFive model is more like a 9.7″ tablet sold with a keyboard acting as a tablet stand, and connecting with the tablet through pogopins. Beside the 4K display, the tablet also features 4 speakers, an audio jack, a USB 3.0 type C port, and a 13MP camera with image and depth of field sensors.

The two devices will run Android 6.0 or Remix OS 3.0, but Rockchip claims RK3399 also support Windows 10 Mobile, Chrome OS, Ubuntu, and Light Biz OS, another Android based OS with desktop improvements.

Pricing and availability are not known at this stage, but we should probably expect Rockchip RK3399 devices to flood the market by the end of the year, or early next year. One RK3399 TV box under the brand FenMi was also showcased at the fair, and it features 2GB RAM, 16GB storage, one USB 3.0 port, two USB 2.0 ports, and one HDMI 2.0 port.

Linux 4.8 Release – Main Changes, ARM & MIPS Architectures

October 4th, 2016 3 comments

Linus Torvalds has officially released Linux 4.8 last Sunday:

So the last week was really quiet, which maybe means that I could probably just have skipped rc8 after all. Oh well, no real harm done.

This obviously means that the merge window for 4.9 is open, and I appreciate the people who already sent in some pull requests early due to upcoming travel or other reasons. I’ll start pulling things tomorrow, and have even the most eager developers and testers hopefully test the final 4.8 release before the next development kernels start coming 😉

Anyway, there’s a few stragging fixes since rc8 listed below: it’s a mixture of arch fixes (arm, mips, sparc, x86), drivers (networking, nvdimm, gpu) and generic code (some core networking, with a few filesystem, cgroup and and vm things).

All of it pretty small, and there really aren’t that many of them. Go forth and test,

Linux 4.7 introduced support for AMD Radeon RX480 GPUs, parallel directory lookups, the new “schedutil” frequency governor with lower latency, EFI ‘Capsule’ firmware updates, and much more.

linux-4-8-changelogSome notable Linux 4.8 changes include:

  • HDMI-CEC framework
  • Kernel documentation system is now based on Sphinx

Xiaomi Mi Pad Tablet with Tegra K1 Processor, 64GB Flash Sells for $120 (Promo)

September 30th, 2016 15 comments

Xiaomi Mi Pad 7.9″ tablet powered by Nvidia Tegra K1 processor was launched in 2014 with either 16 or 64 GB flash, and on July on that year you could buy the version with 64GB storage would sell for $370 and up from sites like Aliexpress. A little over two years, the price has dramatically dropped, and there’s now a promotion for Xiaomi Mi Pad with 64GB storage for $119.99 on GearBest with MiPad64G or MP64GBCSMO coupon.

Xiaomi_MiPadLet’s refresh our memory with the specifications of the tablet:

  • SoC – Nvidia Tegra K1 quad core Cortex A15 processor @ 2.2 GHz with Nvidia 192-core Kepler GPU
  • System Memory – 2GB LPDDR3
  • Storage – 64GB eMMC, extensible to 128GB via microSD card
  • Display – 7.9” IPS display, 2048×1536 resolution; 326 PPI
  • Camera – 8MP rear camera, 5MP front-facing camera
  • Connectivity – 802.11ac 2×2 Wi-Fi, Bluetooth 4.0
  • Audio – 3.5mm audio jack, speaker
  • USB – 1x micro USB port
  • Battery – 6700 mAh battery
  • Dimensions – 202.1 x 135.4 x 8.5 mm
  • Weight – 360 grams

Even by today’s standards, XiaoMi Mi Pad should offer a pretty good performance, but the main downside is the tablet is stuck with Android MIUI V5 operating system based on Android 4.4. English is supported by default, but some other languages such as German, Italian and Dutch, are not supported in the firmware, however GearBest claims they can “offer these language packs”.


Rockchip RK3399 Benchmarks Appear on GeekBench

September 28th, 2016 50 comments

Rockchip RK3399 hexa-core processor with ARM Cortex A72 and A53 cores and a Mali-T860MP GPU will soon be found in TV boxes, development boards, tablets, Chromebooks, virtual reality headset and more, and is widely expected to offer a significant performance boost against previous Rockchip processors, including RK3288, and outperform SoCs from competitors like Amlogic and Allwinner.

We can have a first clue about the performance as Rockchip RK3399 boxes and one tablet are now showing up on GeekBench.


The box is clocked at 1512 MHz, while the tablet is limited to 1416 MHz, but overall single-core score is about 1350 points, while multi-core score hovers around 2,550 points. I’m not that familiar with GeekBench so number don’t tell me anything. Let’s compare it against RK3288 which CPU-wise is the fastest processor I known of from Chinese silicon vendors targeting TV boxes.

rk3399-vs-rk3288There’s a significant single-core performance boost (+73%), and lower multi-core delta (+30%) as expected since RK3399 has 2 fast Cortex A72 cores, 4 low power Cortex-A53 cores, against 4 fast Cortex-A17 cores for RK3288. If you look into the details AES is over 10 times faster on RK3399, so there must be some special instructions used here, or AES hardware acceleration.

Rockchip RK3399 “reference” TV box also has 4GB RAM, so I’m expecting RK3399 devices to come with 2 and 4 GB versions.

RK3399 vs Tegra K1

RK3399 vs Tegra K1

Rockchip RK3399 is also faster than Nvidia Tegra K1 quad core Cortex A15 @ 2.2 GHz for single thread performance, and about equivalent for multi-core tests.

[Update: I also found GFXBench 3D graphics results for RK3399, and compared it to Nvidia Tegra K1.

rk3399-gpu-benchmarkThe Mali-T860MP used in RK3399 is still far from the performance delivered by the Kepler GPU in Tegra K1.

Now if I compare the results to RK3288 (Mali-T764 GPU) based Ugoos UT3s TV box, the score on RK3399 (Mali-T860MP4) is also lower.

rk3399-vs-rk3288-gpuWe’ll have to wait and see here, as we don’t know at which frequency the GPU is running. Both GPUs are supposed to have the same performance according to Wikipedia.]

Thanks to Feelgood for the tip.

DIGMA Plane 8501 3G is the First Tizen 3.0 Tablet

September 26th, 2016 2 comments

Back in 2013, we saw a Tizen 2.0 tablet prototype by Systena, but for whatever reason, it never came to market. Over three years later, a Russian company called DIGMA is about to launch the first Tizen tablet that you should be able to buy (provided you are based in Russia) with DIGMA Plane 8501 3G tablet running Tizen 3.0.

digma-tizen-tabletDIGMA Plane 8501 3G specifications:

  • SoC – Spreadtrum SC7731(G) quad core Cortex A7 processor @ 1.2 GHz with Mali 400MP2 GPU
  • System Memory – 1GB RAM
  • Storage – 8GB flash + micro SD slot up to 32 GB
  • Display – 8″ IPS touchscreen display with 1280×800 resolution
  • Cellular Connectivity – 3G connectivity with dual SIM card support
  • Connectivity – WiFi 802.11 b/g/n, Bluetooth 4.0, GPS/A-GPS
  • Camera – 2MP rear camera with LED flash, 0.3MP front camera
  • USB – micro USB port
  • Battery – 3,800 mAh battery good for about 8 hours
  • Dimensions – 209.8 x 120 x 8.8 mm
  • Weight – 365 grams

This entry-level tablet runs Tizen 3.0 operating system with a new “architecture designed for the Internet of Things”, and targets both businesses and governmental organizations requiring data security and device stability.


There’s no availability nor pricing information for the tablet, but like most devices running an alternative mobile OS, there’s already an Android version selling for 6260 to 6790 Rubles (~$100), so the Tizen tablet should likely be in that price range too.

Hardware Requirements for Discounted Windows 10 Licenses for Entry Level mini PCs, TV Sticks, Tablets, Notebooks, and AiO

September 2nd, 2016 6 comments

Even since the first low cost mini PCs and TV sticks started to come to market there was lots of confusion about Windows 8.1/10 licenses, because while small tablets could be shipped with Windows 8.1 with Bing/Windows 10 with a free license, mini PCs required  a different discounted NTE license costing between $15 and $30. Price differs depending who your ask… So while the cheapest devices normally shipped unactivated, some companies like PiPo decided to install Windows with the latest version to cut costs… Microsoft eventually noticed, and PiPo had to stopped the practise, instead making mini PCs with small displays

The exact hardware requirements were also unclear so far for either the free or discount tablet, but the following table dropped in my email Inbox recently… It explains which hardware is accepted for an Entry level license.

OST means Online Service Terms, and the devices matching the hardware requirements above should be eligible for a discount. A Low End CPUs should be Intel Bay Trail, and Cherry Trail processor, and most likely Braswell and Apollo Lake too, plus some AMD processors. So if you buy a Intel Core iX processor, you should not get a free/cheap Windows license.

Windows 10 mini PCs like Beelink BT7 and Vorke V1 match most requirements of the “WW Entry Desktop/AiO” with a low end Atom X7-Z8700 and Celeron J3160 processor, 4GB RAM, no hard drive, and no optical drive. However, they fail the maximum storage requirements since they ship with at least 64GB internal flash. That means they should be paying the full Windows 10 license, and while they come activated, they are likely in breach of Windows OST. I’ve also been informed Microsoft has been taking legal action against at least one manufacturer of non-compliant devices.
