The hardware specs are a bit lower compared to the Cubieboard8, notably when it comes to RAM, and USB ports. LinkSprite is currently working on Android and Debian for the board, but they also said some developers are also working on Chromium OS. The board is expected to be available next month, and they hope to keep the price below $100.

The video below is 19 minutes long, but only the first 1 minute and 30 seconds are about their new Octa-core board. The rest of the video includes:

  • History of PcDuino boards including a new PcDuino3 Nano soon to be available
  • A version of Scratch for PcDuino board with an hardware tab to program GPIOs using the program’s graphical user interface.
  • Quick demo of a Robot powered by a PcDuino board
  • PcDuino for education used in schools in Colorado, USA, Germany, and China. Resources are available at learn.linksprite.com

  • Dimensions – 241 x 169 x 7.9 mm
  • Weight – 490 g

The tablet is said to sell with a USB cable, the power adapter, and a user’s manual. Beside being one of the most powerful processor on the market, AllWinner A80 is supposed to support 5 operating systems: Android, Ubuntu, Chrome/Chromium OS, Firefox OS, and Windows RT which should make it a nice candidate to try out various OS and play around, albeit a tablet does not provide the most hacker friendly form factor there is.

Pandawill pre-sells Onda V989 tablet for $239.99, Geekbuying for $229.99, and “onda-tablet”, which may or may not be the official store, pre-ells it for $219.99, but without shipping. It’s also available on several Aliexpress sellers. The tablet is expected to ship on July 31. The company already sold 500 beta tablets in China for 999 CNY (~$161) yesterday, and the regular price will be 1099 CNY (~$177) according to my sources in AllWinner. You may be able to find some more information on Onda V989 product page (in Chinese), including two firmware versions for V1 and V2 tablets…?

Thanks to Marius for the tip.

Mediatek MT6795 Octa Core ARM Cortex A53 Processor to Launch in Q4 2014

July 11th, 2014 4 comments

Mediatek had already announced two 64-bit ARM SoCs with MT6732 and MT6752 boasting respectively four and eight Cortex A53 cores for mainstream and premium smartphones. There are now reports that the company will launch an eight core 64-bit LTE SoC with HMP architecture. Since HMP (Heterogeneous Multi-Processing) is only used for big.LITTLE processing, and Mediatek does not have an history of making their own custom ARM cores, we can safely assume the processor will feature four Cortex A53 little core, and four Cortex A57 big cores. [Update: finally it's eight ARM Cortex A53 cores, no HMP here].

MTK6795What we know about MT6795 so far:

  • Processor – 64-bit Octa core ARM Cortex A53 cores @ 2.2 GHz
  • GPU- Imagination Technology G6200 @ 700 MHz
  • Memory I/F – 2x LPDDR3 @ 933 MHz (PoP)
  • Camera I/F – 20MP@30fps using a dual ISP
  • Display – Up to WQXGA (2560×1600)
  • Video
    • Decoding – 4K2K @ 30 fps (H.265 and H.264)
    • Encoding – 4K2K @ 30 fps (H.265)
  • Modem – LTE FDD/TDD R9 Cat4, DC-HSPA+ 42/11Mpbs, TD-SCDMA/EDGE
  • Connectivity – Wi-Fi 802.11ac, Bluetooth, FM, GPS, Glonass and Beidou via MT6630 chip (external)
  • Process – 28 nm

That’s only the second mobile SoC I’ve heard with ARMv8 big.LITTLE, the other being Qualcomm Snapdragon 810, and it looks like MT6795 will be a direct competitor with LTE support. The Adreno 430 GPU is however likely to outperform Imagination Technology G6200 GPU chosen in the new Mediatek SoC. The company also claims MT6795 will provide an easy upgrade for OEM from their MT6595 LTE SoC, a big.LITTLE ARMv7 processor (Cortex A17 + Cortex A7).

MT6795 mass production is scheduled for December 2014, so actual products will probably be available in Q1 2015. Devices based on Snapdragon 810 are also planned for Q1/H1 2015.

The company can also provide USB modules / dongles for optical S/PDIF output, Gigabit Ethernet (USB 3.0 to Ethernet adapter), Wi-Fi 802.11n/g/n 1T1R with antenna, and 2.5″/3.5″ SATA drives (USB 3.0 to SATA III adapter).  Hardkernel will provide Ubuntu 14.04 support with OpenGL ES + OpenCL support, and Android 4.4.2 both based on Linux kernel 3.10 LTS, and the source code will soon be available on their github account. This is also the first ODROID board that supports Heterogeneous Multi-Processing / Global Task Scheduling implementation of big.LITTLE processing. You can get an overview of the board and see Ubuntu 14.04 running OpenGL ES 3.0 demo, and playing a windowed YouTube video – which makes me think hardware video decoding may not be implemented yet – in the video below.

ODROID-XU3 comes with a plastic case, an active cooler and a 5V/4A power adapter, and you get pre-order it for $179 + shipping on Hardkernel website with delivery schedule for the 18th of August 2014. There’s no internal storage with the board so you’ll need a micro SD card (Class 10 strongly recommended), or even better purchased one of the eMMC module with the board. The 16GB eMMC sells for $39 and includes an adapter to connect it to your PC. You can get more information, and/or purchase the board and a few of its 23 accessories on Hardkernel’s ODROID-XU3 product page.

Pictures and Specs for CubieBoard 8 Development Board Powered by AllWinner A80 SoC

July 1st, 2014 14 comments

Back in April, AllWinner announced partnerships with Linksprite and CubieTech for respectively PcDuino 8 and Cubieboard 8 development boards to feature  AllWinner A80 octa core ARM Cortex 15/A7 big.little SoC. However, at the time all we got was some photo-shopped pictures of older versions of the boards with an A80 processor pasted by graphics designers. Some pictures of Cubieboard 8 have now surfaced, and they are clear enough so that we can start to get most of the specs.

Here are Cubieboard 8 specifications derived from the pictures (incomplete because we don’t have pictures of the back of the board):

  • SoC – AllWinner A80 octa core big.LITTLE processor with 4 ARM Cortex A15 cores, 4 Cortex A7 cores, and Imagination PowerVR G6200 GPU
  • System Memory – 2GB DDR3 (4x SKhynix H5TQ4G83AFR – 4Gbit RAM chips) – TBC in case they’ve added more RAM chips at the back, unlikely IMHO.
  • Storage – TBD (At the back?) + SD Card slot
  • Video Output – HDMI and VGA
  • Audio I/O – HDMI, Line In, Line Out, and optical S/PDIF
  • Connectivity – Gigabit Ethernet, Wi-Fi 802.11 b/g/n + Bluetooth 4.0 (AP6330 module)
  • USB – 4x USB 2.0 host ports, 1x Micro-B USB 3.0 port
  • Debugging – UART close to VGA port (TBC)
  • Expansion Header – 20 pin header
  • Misc – RTC battery slot, 2 LEDs, 3 push buttons
  • Power – Round DC power jack (5V?)

That’s about all we know for now. AllWinner announced support for Android, Chrome OS (Chromium OS?), Ubuntu, Firefox OS, and Windows RT, so hopefully most will also be available with the board expect probably Windows RT, and possibly Chrome OS. Price and availability are unknown, but since AllWinner A80 MP is supposed to start this month, and in a previous interview, a $100 price target had been talked about, I’m really expecting the board to be available for around $100 by the end of this month.

Thanks to Jibril!

Onda V989 Tablet Powered by AllWinner A80T Achieves Close to 50,000 Points in Antutu

June 17th, 2014 9 comments

Teclast T97 was one the first tablet based on AllWinner A80, an octa-core CortexA15/A7 big.little processor with PowerVR G6230 GPU. It was announced way too early last December… There’s now another tablet much closer to an actual retail availability called Onda V989 featuring AllWinner A80T with a 9.7″ display and 2 or 4 GB RAM that come close to the top of the Antutu scoreboard with 48102 points.

AllWinner_A80TUnfortunately that’s all we know about this tablet at this stage. I’m not sure what A80T means, AllWinner A80 Tablet version?, or AllWinner A80 Turbo, with higher clock frequencies? There has also been some sort of silly season with benchmark related to AllWinner A80 with scores ranging from 23674 to 48102 points in Antutu as shown below for Onda V989. The low score was achieved when A80′s Cortex A15 cores were allegedly clocked at 1.2GHz , but it should be closer to 2GHz when it ships, unless there are serious overheating issues… We’ll find out the truth once products are available, hopefully in July, but the target release for AllWinner A80 seems to be pushed to the future every month…
