AllWinner A33 Quad Core Tablets Are Now Available for $60 and Up

July 29th, 2014 6 comments

AllWinner A33 is a new quad core Cortex A7 processor pin-to-pin compatible will AllWinner A23 dual core processor, that costs less than $5 with the power management IC (AXP223). Tablets based on the new processor are now available for sale, and just as low as $60 including shipping on Aliexpress. All models currently listed feature 9″ to 10″ displays, so it’s safe to expect 7″ tablets to be close to $50.
AllWinner_A33_Tablet
Let’s check the specs of one of the no-name 9″ tablets currently available:

  • SoC – AllWinner A33 quad core Cortex A7 processor @ 1.3 GHz (Overclocked to 1.5GHz???) with Mali-400MP2 GPU
  • System Memory – 512MB RAM
  • Storage – 8GB NAND FLASH + microSD card slot (Up to 32GB)
  • Display – 9″ capacitive touch screen (800 x 480 pixels, 5 points touch)
  • Connectivity – 802.11 b/g/n Wi-Fi and Bluetooth. 3G is supported via external 3G USB dongle.
  • Camera – 0.3M front camera,  1.3MP rear camera
  • USB – 1x micro USB 2.0 port
  • Audio – Speakers, earphone jack
  • Video Codecs - H.264, VP8, RV, WMV, AVS, H.263, MPEG4 up to 1080p
  • Audio formats – MP3, WMA, WAV, ACC, ACC+
  • Sensors – Gravity sensor
  • Battery – 3000 mAH Lithium battery
  • Dimensions – 263 x 165 x 11.5 mm
  • Weight – 650 gram???

The tablet runs Android 4.4.2, and comes with a 5V/2A power adapter, a OTG cable, a micro USB to USB cable, and a user’s manual. 512 MB RAM used to be a limitation in previous version of Android, but that might be OK with Android 4.4, as Google optimized Android for device with 512 MB RAM. I’d expect 800×480 resolution for a 9″ display will be somewhat pixelated, and the dual cameras to be a disaster. But if it’s for a first tablet, for a kid, or for tablet used as a control panel it could be an option. I and a few people around me purchased low cost tablets in the last few years, and I found them to be mostly usable, but you can’t expect to keep them to last very long because of the battery which will survive 6 months to a little over a year depending on your usage…

You may also want to read the press release for details about SmartColor image processing technology, video decoder performance, and power consumption (up to 300 hours in standaby mode with a 4,000 mAh battery).

  • 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.

AllWinner V10 and V15 SoCs Target Video Recording Applications

July 9th, 2014 1 comment

AllWinner A-series that can be found in tablets and media players are pretty well known, but AllWinner also has V-Series processors with V10 and V15. A first glance, AllWinner V10 is quite similar to AllWinner A31 with a quad core Cortex A7 CPU coupled with a PowerVR SGX544MP2 GPU, and AllWinner V15 has the same CPU/GPU combo as AllWinner A10 (CortexA8/Mali-400). But AllWinner V-Series are actually video encoders targeting applications such as IP cameras, car DVRs, and sports digital video cameras thanks to features such as motion detection, video scaling, and digital watermarking.

AllWinner V10 Block Diagram

AllWinner V10 Block Diagram

Let’s go through AllWinner V10 specifications, and I’ll mark differences with AllWinner A31, or features not mentioned in A31 specs, in bold:

  • CPU – Quad-core ARM Cortex-A7 with· 256KB L1 cache, 1MB L2 cache
  • GPU – PowerVR SGX544MP2 compliant with OpenCL 1.1 EP and delivering up to 20GFLOPS.
  • Memory – 32-bit DDR3/LPDDR2 SDRAM controller, supporting up to 2GB; NAND I/F
  • Video
    • Supports H.264 High Profile 1080p@60fps video encoding
    • Digital watermarking
    • Motion detection
    • CBR/VBR bit rate control mode
    • Supports UHD@24fps video decoding
    • Supports multi-format video decoding including MPEG 1/2/4, H.264, VP8, AVS,VC-1, etc.
    • Supports independent encoding and decoding
    • 1/16 ~ 16x scaling
  • Video Input/Output
    • Supports 12-bit parallel CSI and 4-lane MIPI CSI
    • Supports up to 12M CMOS sensor
    • Supports RGB LCD/LVDS/MIPI DSI/HDMI
    • Supports one video layer and two graphic layers
    • Supports scaling up to 4K x 4K
  • HawkView ISP
    • Auto exposure/focus/white balance (AE/AF/AWB)
    • Dynamic range control (DRC)
    • Color enhancement
    • Noise reduction
  • Audio Codec
    • Integrated Hi-Fi 100dB audio codec
    • Three integrated differential analog mic amplifiers for headset and phone
    • One digital mic interface with software noise cancellation
  • Peripherals
    • 3 x USB ports
    • 4 x SD card 3.0
    • RTP/CTP
    • GMAC/EMAC
  • Package – BGA609, 18mm x 18mm, 0.65 pitch

AllWinner V10 also appears to be lacking 3840×1080 3D decoding ability found in A31, and may not have a dual band RAM interface, and no support for LPDDR3 memory. I’m not sure if A31 also supports independent encoding and decoding, or that would means Skype or Google Hangout calls are partially handled by software. AllWinner provides support for Android and Linux operating systems for the V10 and V15 processor, specifically Android 4.4 for V10. AllWinner V15 has similar features as V10 but only comes with a single Cortex A8 core, a Mali-400 GPU, supports 1080p decoding, 720p encoding, and features less peripherals. It’s also smaller with a BGA336 (14mm x 14mm) package.

I could not find any development boards, nor products based on AllWinner V10 and V15. There may be some, but the processors are seldom advertised in devices like digital cameras, and digital video recorders. I’ve asked some details to AllWinner, and I’ll update this post if I get an answer.

You can may find more information in AllWinner V10 and V15 on their respective product pages.

AllWinner A33 Quad Core Processor to Cost $5 With PMIC, Tablets Starting at $40

June 23rd, 2014 16 comments

With their latest A33 SoC, Allwinner may have put a nail in the coffin of dual core application processor for tablets, as Eva Wu, AllWinner’s Marketing Manager,  has just released some pricing info, and AllWinner A33 with AXP223 PMIC (Power Management Integrated Circuit) reference price is only $4.99, paving the way for ultra cheap quad core Android tablets.

AllWinner A33 Tablet PCBA (Click to Enlarge)

AllWinner A33 Tablet PCBA (Click to Enlarge)

I’ve also been given some estimates for (factory) prices for different tablet’s types powered by AllWinner A33:

  • About $40 for 7″ tablets (800×480) with 1GB DDR3, and 8GB Flash.
  • About $45 for 7.85″ tablets (1024×768) with 1GB DDR3, and 8GB Flash.
  • About $50 for 8″ tablets (1280×800) with 1GB DDR3, 8GB Flash.

With four ARM Cortex A7 cores, a Mali-400MP2 GPU, and limited display resolutions, you won’t get an amazing user experience, but for a first tablet, or a kid’s tablet, it looks pretty good value. I estimate that Chinese stores may sell them for around $65 to $80 including shipping. AllWinner A33 SoC production will start in early July, so the first tablets based on this SoC should also start to become available in July.

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…

June 3rd, 2014 5 comments

Allwinner has just announced a new quad cortex ARM Cortex A7 SoC for entry-level Android tablets. AllWinner A33  shares many of the features of AllWinner A23 dual core Cortex A7, including an ARM Mali-400MP2 GPU, and provides pin-to-pin compatibility, with the main difference being the upgrade from two to four Cortex A7 cores.

AllWinner_A31_Block_Diagram

The company has already disclosed the main specifications of their new SoC:

  • CPU – Quad core ARM Cortex A7 with 256 KB L1 Cache, 512KB L2 cache
  • GPU – ARM Mali-400MP2 with support for OpenGL ES 2.0/VG 1.1 standards
  • Memory
    • DDR3/DDR3L SDRAM controller
    • 8-bit NAND/eMMC flash controller
  •  Video
    • Decoding – 1080p60 video playback for MPEG-1/2, MPEG 4 SP/ASP GMC, H.263, H.264, WMV9/VC-1, VP8, and more
    • Encoding – 1080p60 for H.264
    • Complies with RTSP, HTTP, HLS, RTMP, MMS streaming protocols
    • Supports OpenMAX API
  • Display
    • 1 to 4 lane MIPI DSI up to 1280×800
    • RGB/CPU/LVDSLCD up to 1280×800

  • USB – USB OTG. USB Host, and HSIC
  • Other I/Os – 3x PWM, 2x SPI, 4x TWI (I2C), 6x UART/RSB
  • Misc – RTC, Security system for DRM
  • PMIC – AXP223 with support for 21-channel power output, 2.1A charging. Complies with USB 3.0 supply standard

AllWinner A33 will support Android 4.4 and above, so no official multi-OS support like other higher-end AllWinner SoCs.

AllWinner A31, A31s, A33 and A23 Comparison

AllWinner A31, A31s, A33, A20 and A23 Features Comparison

You may have noticed AllWinner A33 is provided in a BGA282 package, and AllWinner A23 in a BGA280 package, so we’ve got two extra pins there… It could mean you can’t simply replace A23 by A33 on exiting designs, but it should be possible to make a new board that supports both A23 and A33, just like it is done today with AllWinner A10 and A20.

AllWinner A33 is sampling now, and the company expects the first commercially available tablet based on the platform to be available in July.

ARM Cortex A15/A17 SoCs Comparison – Nvidia Tegra K1 vs Samsung Exynos 5422 vs Rockchip RK3288 vs AllWinner A80

May 21st, 2014 10 comments

We’re now starting to get quite a few players with ARM Cortex A15 cores on the market, as well as some with ARM Cortex A17. So a comparison table of different quad and octa SoCs might be a useful thing to do. I’ve put aside SoCs such as HiSilicon K3V3, and OMAP5, and focused on the four latest processors: Nvidia Tegra K1 (32-bit), Samsung Exynos 5422, Rockchip RK3288 and AllWinner A80. I haven’t included Mediatek MT6595 and Qualcomm SnapDragon 805, because the two companies mainly focus on smartphones and tablets (although it appears to be slowly changing for Qualcomm), documentation is usually difficult or impossible to find, and in the case of Qualcomm they use their own ARMv7 Krait cores.

rk3288_a80_tegra_k1_exynos_5_octaI’ve highlighted some features in green, in case a particular SoC appears to have an edge.

Arndale Octa for $179
Announced: ODROID XU-2 (Price not available)

First some general comments:

  1. As details are not always available, and I had to go through thousands of pages of documentation, it’s possible some information is incorrect or missing. So I’d be grateful if anybody points out mistakes in the table.
  2. In L2 Cache = xx MB + xx KB refers to the cache for the bit processors (A15) + the cache for the LITTLE processors (A7) or the companion core.
  3. The “Other I/Os” section is mainly for reference, as I’m sure parts are missing here.
  4. I haven’t addressed power consumption of the different SoC, since I don’t believe numbers provided by the SoC vendors are directly comparable.
  5. Antutu scores are interesting to get an idea of the performance, but we should bear in mind AllWinner A80 and Tegra K1 scores appear to have been achieved with development hardware, which may not have the same thermal constraints as the tablet and smartphone used with Rockchip RK3288 and Exynos 5422.

Based on this comparison table, Nvidia Tegra K1 really seems to have the best package in terms of performance, 3D and GPGPU APIs, and peripheral interfaces such as SATA and PCIe which are missing on all other SoCs. The downsides are video encoding is only supported up to 1440p, and there’s no Ethernet MAC. That means no 4K hardware video decoding, although an article from Anandtech mentioned the company demos 4K 30 fps using the Kepler GPU. The way to add Ethernet with Tegra K1 is to use an external Ethernet Control chip and connect it to the PCI Express port, as they did for Jetson TK1 development board. It’s also likely Tegra K1 is more expensive than all other three, but it’s very versatile and could be found in various type of products: tablets, mini PCs, laptops and so on. Linux and Android are supported, and since the company seem inclined to go open source, it’s likely any Linux based OS can be supported by the platform.

Rockchip RK3288 should be one of the more cost effective platform in the table, but trade offs includes 1MB L2 cache (vs 2MB for others), an 4GB RAM limitation, the lack of USB 3.0 interfaces, and lower overall performance. However it’s the only SoC that 100% 4K ready here with HDMI 2.0, HEVC decode at up to 4K @ 60fps, as well as Gigabit Ethernet. ARM Cortex A17 should also have lower consumption compared to ARM Cortex A15, but it’s unclear how it will compare against big.LITTLE solution. This will probably remain a gray area because power efficiency will highly depend on the payload. RK3288 has already been demoed on hardware running Android and Chromium OS.

AllWinner A80 has performance very close to Tegra K1, apparently supports VP9 (N.B: However, I had been asked to remove VP9 from an AllWinner A80 graphics once), supports 4K30 video decoding, USB 3.0. Apart from the lack of SATA and PCIe interfaces, and OpenGL 4.4 support, AllWinner SoC appears to have few drawbacks compared to Tegra K1, so we’ll have to see how it compares in terms of price versus Rockchip RK3288. The company has also announced support for 5 operating systems for A80: Android, Chrome OS, Ubuntu, Windows 8, and Firefox OS. So they must have worked with Imagination Technology to support the PowerVR GPU on these OS.

Samsung Exynos 5422 appears to be just short of AllWinner A80 and Tegra K1 performance, and the company has dropped some interfaces such as SATA, PCIe, LVDS, Ethernet MAC,  that makes it a little less versatile than other SoCs, and more targeted at tablets and smartphones. It’s the only SoC that supports both 8K encode and decode (H.264 and VP8 only), but lacks HEVC/H.265 hardware support. It’s also the only SoC to support eMMC 5.0, instead of just eMMC 4.5, which can potentially double the IO performance (400MB/s max instead of 200 MB/s).
