July 17th, 2014 11 comments

AllWinner A80 octa-core big.LITTLE has been delayed several times, but it appears products based on the latest AllWinner application processor can finally be pre-ordered. One of them is Onda V989,  an Android 4.4 tablet with a 9.7″ 2048 x 1536 pixel display, 2GB RAM and 32GB flash, that’s supposed to reach over 48,000 in Antutu, but actually gets a little over 32,000 points in Antutu X.

Onda_V989Onda V989 tablet specifications:

  • SoC – AllWinner A80T octa core bit.LITTLE processor with 4x ARM Cortex A7 cores @ ?? GHz and 4x ARM Cortex A15 cores @ 2GHz, and PowerVR G6230 GPU
  • System Memory – 2GB DDR3
  • Storage – 32GB NAND flash + micro SD/SDHC slot (up to 128GB)
  • Display – 9.7″  IPS display with 10-point capacitive touchscreen, 2048 x 1536 resolution
  • Video Output – micro HDMI (up to 1080p)
  • Audio I/O – Stereo speakers, built-in microphone, 3.5mm earphone jack, and HDMI
  • Connectivity – 802.11 b/g/n Wi-Fi, Bluetooth 4.0 . 3G is supported via external dongle.

  • 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.

Hardkernel Unveils $179 ODROID-XU3 Development Board Powered by Samsung Exynos 5422 SoC

July 8th, 2014 8 comments

Remember ODROID-XU2 development board based on Exynos 5420? The bad news is that it apparently got scrapped, but the good news is that it gave birth to ODROID-XU3 development board powered by the latest Samsung Exynos 5422 octa core big.LITTLE SoC with support for Ubuntu 14.04 and Android 4.4, including GPU 3D acceleration with the company promising a full desktop experience in Ubuntu.

ODROID-XU3ODROID-XU3 specifications:

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.

Cubieboard 8 (Click to Enlarge)

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…

Teclast P98 3G Tablet is Powered by Mediatek MT8135 big.LITTLE SoC

June 11th, 2014 12 comments

Several companies have announced processors with big.LITTLE processing technology, but until recently only some Samsung Exynos 5 processors (Exynos 5420, 5422, and 5260) are found in products available for purchase. Available a few weeks ago, Teclast P98 3G tablet changes that as it is powered by Mediatek MT8135 quad core processor featuring big.LITTLE processing.

Teclast_P98_3G_big-little-tablet

Teclast P98 3G specifications:

  • SoC - Mediatek MT8135 (aka MTK8135) with two ARM Cortex A15 cores @ 1.5 GHz (1MB L2 cache), two ARM Cortex A7 cores @ 1.2 GHz (256KB L2 cache) in big.LITTLE configuration, and Imagination PowerVR GC6200 GPU
  • System Memory –  2GB DDR3
  • Storage – 32GB eMMC (UP to 120 MB/s) + micro SD slot
  • Display - 9.7″ 2048×1536 IPS screen
  • Video Output – HDMI
  • Audio – Earphone jack, and AAC stereo speakers
  • Connectivity - WiFi 802.11b/g/n, Bluetooth 4.0, GPS, FM
  • Cellular – Built-in 3G WCDMA modem and one SIM card slot (Not for Wi-Fi only version)
  • USB – 1x micro USB
  • Camera –  2.0 MP front camera, 12.6MP rear camera
  • Sensors – G-sensor, compass, 3-axis gyro
  • Misc – Home, Vol +/-, and Power buttons,
  • Battery – 8,500 mAh, or 7,500 mAh for Wi-Fi only version.
  • Battery Life – 8 hours video playback time (Wi-Fi off), 15 hours audio playback (Wi-Fi and screen off, headphone output)
  • Dimensions – 239.5mm(L) x 180.5mm(W) x 8.2mm(H)
  • Weight - 608.2g

The tablet runs Android 4.2.2, and comes with a 5V/1.5V charger, a micro USB cable, and a user’s manual. Although the specs mention a Wi-Fi only version I could not find it anywhere for sale.

According to one seller, the Antutu score is 20500, which seems decent considering the screen resolution. Please noe that Antutu detects the CPU frequency as 1.2 GHz. I’m not quite sure how Antutu handles heterogeneous system with different CPU cores, so this may be a bug, or really means the Cortex A15 cores are clocked @ 1.2 GHz instead fo the 1.5 GHz advertised.

It would be interesting to find out more about battery life, but as usual it’s more complicated as there aren’t any standard tests. However, in some use cases it should be similar to a dual core Cortex A7 system, as the Cortex A15 cores should only be used for CPU intensive tasks, for instance while loading apps, or web pages. Audio and video playback should fully rely on the Cortex A7 cores.

Teclast P98 3G is available from several shops on Aliexpress as well as Teclast.org for about $240 including shipping. In China, the tablet sells for 1249 CNY (~204 USD) on Tmall.
