AllWinner A80 OptimusBoard Octa-core big.LITTLE Development Board is Now Available … for $169

August 16th, 2014 30 comments

A80 OptimusBoard powered by AllWinner A80 octa-core processor with four Cortex A15 and four Cortex A7 in big.LITTLE configuration had been announced at the end of 2013, and after numerous delays, several boards have recently been sent to developers and companies such as miniNodes, Linuxium, and others. The company behind the board is actually Shenzhen Merrii Technology (aka WITS), which had done all earlier development kits for AllWinner, and they’ve now made the board available for purchase on Aliexpress. Unfortunately the company has decided to leave to low cost development boards market to the likes of Cubieboard8 and PCDuino8, as A80 OptimusBoard sells for $345 plus about $30 for shipping by courier.[Update: they now offer it for $169]

Samsung Announces Exynos 5430 SoC, Manufactured with 20nm Process

August 14th, 2014 4 comments

Samsung already have a few octa-core big.LITTLE SoCs part of Exynos 5 Octa family with Exynos 5410, Exynos 5420, and Exynos 5422/5800, all based on 28nm process. The company has just announced a new Exynos 5 Octa processors with Exynos 5430, but this time manufactured using 20nm High-K Metal Gate (HKMG) process technology providing 25% less power consumption compared to 28nm Exynos SoCs.

Samsung_Exynos_5430

Exynos 5430 SoC will feature four ARM Cortex A15 cores at 1.8 GHz, four Cortex A7 cores at 1.3 GHz, supports WQHD (2560×1440) and WQXGA (2560 x 1600) displays using hibernation display and Mobile Image compression (MIC) in order to lower power consumption. It also said to support HDMI, come with a Multi Format Codec (MFC) supporting HEVC/H.265 decoding, as well as an enhanced dual ISP, and up to 17GB/s of memory bandwidth. That’s about all the information I could get at this point. The CPU core frequencies are lower than Exynos 5422, but the maximum memory bandwidth appears to be higher (17GB/s vs 14.9GB/s), and of course the power consumption is significantly lower. It will also be found in the recently announced Galaxy Alpha smartphone.

More details should eventually surface on Samsung Exynos 5430 page.

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.
