Infocus CS1 A83 (C2107) Android Tablet Review

I’ve already shown some pictures, listed specs and reported Antutu benchmark results for Infocus CS1 A83 Android tablet powered by Allwinner A83T octa core processor. I’ve been using this tablet as my main mobile device for about a week, and for about 3 to 5 hours a day, and I’m now ready to write a full review reporting my experience with this Full HD tablet. General Impressions I mainly use a tablet to browse the web, check emails, play some casual games like Candy Crush Saga, watch some YouTube videos, and Skype calls, and I could not really fault the tablet for any of these applications. Having said that, my reference device is only ThL W200 smartphone powered by Mediatek MT6589T processor with a 5″ display @ 1280×720, and for all the tasks listed Infocus tablet is much better because it’s more responsive, the 1920×1200 is crisp, and the cameras […]

Linux 3.18 Released

Linus Torvalds released Linux Kernel 3.18 last Sunday: It’s been a quiet week, and the patch from rc7 is tiny, so 3.18 is out. I’d love to say that we’ve figured out the problem that plagues 3.17 for a couple of people, but we haven’t. At the same time, there’s absolutely no point in having everybody else twiddling their thumbs when a couple of people are actively trying to bisect an older issue, so holding up the release just didn’t make sense. Especially since that would just have then held things up entirely over the holiday break. So the merge window for 3.19 is open, and DaveJ will hopefully get his bisection done (or at least narrow things down sufficiently that we have that “Ahaa” moment) over the next week. But in solidarity with Dave (and to make my life easier too 😉 let’s try to avoid introducing any _new_ […]

Merrii A80 Hummingbird Octa-core Development Board Supports HDMI, VGA, and eDP Video Outputs

Up to now at least three boards based on Allwinner A80 processor were available: A80 OptimusBoard by Merrii, pCDuino8 by Linksprite, and Cubieboard4 by Cubitech, and the first two boards are basically the same. Merrii has now introduced a new board which they call “A80 Hummingbird H8”, with more features and ports including HDMI, VGA and eDP video outputs, LVDS / MIPI DSI display interfaces, MIPI CSI camera interface, an RTC with battery and more. Merri H8 specifications: SoC – AllWinner A80 octa-core processor with 4x Cortex 15, 4x Cortex A7 cores in big.LITTLE configuration with Imagination Technologies PowerVR GC6230 GPU compliant with OpenGL ES 3.0/2.0/11, OpenCL 1.1, and DirectX 9.3 System Memory – 2GB DDR3 Storage – 8GB internal storage (Sandisk SDIN7DU2 iNAND Flash), micro SD slot up to 32 GB Video Output/ Display Interfaces HDMI 1.4 up to 4K UHD resolution VGA port eDP v1.2 up to 2560×1600 @ […]

Allwinner A83T Tablet Unboxing, First Boot, and Benchmarks

Allwinner & HonHai Precision Industry, better known as Foxconn, sent me an Infocus tablet based on Allwinner A83T processor with eight Cortex A7 cores up to 2GHz, and a PowerVR SGX544 GPU. Today, I’ll list the specifications of this tablet, show unboxing pictures, first boot video, and run Antutu benchmark. Infocus New Tab CS1 A83 / C2107 Specifications The invoice calls the tablet “New Tab CS1 A83”, but Android reports the model as C2107, so I’m not fully sure what will be the actual name. It might well be New Tab CS1 A83, as I could find an Infocus an earlier Infocus New Tab CS1 tablet powered by Allwinner A31. Anyway, here are the specifications I could derive from the device, and running Antutu/CPU-Z on the device: SoC – Allwinner A83T octa-core ARM Cortex-A7 @ 2.0 GHz with PowerVR SGX544MP GPU supporting OpenGL ES 2.0/1.1, OpenCL 1.1, DX 9.3. System […]

Banana Pi, and the recently announced Banana Pro, are Android & Linux development boards based on Allwinner A20, with a form factor similar to Raspberry Pi Model B and B+ boards respectively. A new revision of the board is now available with Banana Pi M2 powered by Allwinner A31s quad core processor, and in a form factor similar to R-Pi B+. Banana Pi M2 specifications: SoC – Allwinner A31s quad core Cortex A7 @ 1.0 GHz with PowerVR SGX544MP2 GPU System Memory – 1GB DDR3 Storage – Micro SD slot up to 64GB Connectivity – 10/100/1000 Ethernet, 802.11 b/g/n Wi-Fi (Realtek) Video Output – HDMI, CVBS, and LVDS/RGB header Audio Output – HDMI and 3.5mm stereo jack Camera – CSI connector USB – 2x USB 2.0 host ports + micro USB port (power only) Debugging – UART pins for serial console Expansion Header – 40-pin R-Pi “somewhat” compatible header with […]

Preliminary Ubuntu Image for Tronsmart Draco AW80 Octa-core mini PC

Tronsmart Draco AW80 is an Allwinner A80 based mini PC pre-loaded with Android 4.4. A preliminary Ubuntu image is now available for the device. It’s still a little buggy, but you can access LXDE desktop on an HDMI TV, Ethernet is working, and web browsing is apparently working nicely. Known bugs include FAT32 partitions are read-only, wireless mouse and keyboard are not working (USB versions are OK), shutdown does not work, the user interface is not as snappy as in Android, and YouTube video playback is choppy. The last two issues could be related to the lack of VPU and GPU drivers providing video hardware decoding, and 2D/3D hardware acceleration respectively. The good news is that the company working on Draco AW80 got the GPU drivers from Imagination, and an updated image could be available with hardware acceleration. I’m not sure sure about VPU support, which is extremely important if […]

Rikomagic MK80, MK12, MK05, V5 Android TV Boxes and Sticks Are Now Available for Purchase

Rikomagic unveiled their MK80, MK12 and MK05 Android media players a few week ago, and somehow I missed (or ignored) their Rikomagic V5 TV stick, which looks very similar to Jesurun T034 / MK802 V powered with Rockchip RK3288 processor, and features an Ethernet port, but differs as full-sized USB ports are used instead of mix of micro and full-sized USB ports. All four devices, even five with MK80 Plus, are now available on Rikomagic’s Aliexpress store. MK80 and MK80 Plus are Android mini PCs powered by Allwinner A80 SoC, and are probably using the same Sunchip board as Tronsmart Draco AW80 Meta and Telos, The standard version comes with 2GB RAM, 16GB eMMC, and the “Plus” version with 4GB RAM, and 32GB eMMC, and can be purchased respectively for $155.90 and $199.99 including shipping. MK12 is based on the new Amlogic S812 processor which adds HEVC/H.265 hardware video decoding […]

AllWinner A80 Octa Core big.LITTLE Processor CPU Usage Under Various Loads in Android 4.4 (Video)

Allwinner A80 is one of the few octa core processors featuring ARM’s big.LITTLE technology currently available on the market. The processor comes with four ARM Cortex A15 (big) cores, and four ARM Cortex A7 (LITTLE) core, and tasks will be scheduled to different processor depending on the load to optimize power consumption on mobile devices. However, earlier big.LITTLE processors like Samsung Exynos 5410 has some serious limitations, as they only supported “cluster migration” meaning you could only use the Cortex A7 cluster or Cortex A15 cluster at any given time, so Exynos 5410 could only make use of four cores at most due to hardware limitations. They also used to be two software implementations: In-kernel Switching (IKS) and Global Task Scheduling (GTS). The former could only handle one type of core at the same, and the latter, which I believe is now used in all new devices, can handle any […]
