Samsung Chromebook 2 Features Exynos 5 Octa SoC, Comes with either 11.6″ or 13.3″ Display

March 4th, 2014 12 comments

Samsung has just launched the Chromebook 2 Series with two models based on on Exynos 5 Octa SoC, available in 11.6″ (1366×768) and 13.3″ (1920×1080) configurations, and featuring 4GB RAM, 16GB eMMC, and a longer battery life thanks partially to big.LITTLE processing technology. Samsung expects the new Chromebooks to be used for work, education, and entertainment.

Thanks to strong hardware specifications, these new ARM based Chromebooks will certainly offer performance similar to, or even outperforming, existing many Intel Celeron based Chromebooks, and at the same time offer a longer battery life. It’s a nice upgrade to the Exynos 5250 powered Chromebook launched in 2012, especially the addition of a model with a 13.3″ display with FHD resolution. The 13.3″ model has an Exynos 5 Octa processor clocked at 2.1GHz which should be the latest Exynos 5422, whereas the 11.6″ model might use Exynos 5420 instead (TBC).

The company also mention the 13.3″ Chromebook 2 features high-power stereo speakers (2Wx2) and a noise reducing array microphone optimized for Google+ Hangouts messaging and video calling. Thanks to Chrome OS, the laptops will boot within seconds, be updated automatically, and all information and files are saved, and encrypted to your account. Some premium adds such as Air Droid Premium, Wunderlist Pro, and LittleBridge.com will be included with the device.

The 11″ and 13.3″ Chromebook 2 will be available (in the US) in April 2014 for respectively $319.99 and $399.99.

Samsung loaned a few Chromebooks 2 to blogs in the US for some reviews and hands-on, and the reviewers were left with mostly positive first impressions:

Samsung Unveils Exynos 5 Octa 5422 and Exynos 5 Hexa 5260 SoCs

February 26th, 2014 1 comment

As expected, Samsung announced the Exynos 5 Hexa 5260 hexa-core processor and, the not-quite-expected Exynos 5 Octa 5422 octa-core processor at Mobile World Congress, both of which feature ARM’s big.LITTLE processing technology, and ARM Mali-T628 GPU. Still no news about their 64-bit processor.

Exynos_5_octaExynos 5260 will feature two ARM Cortex A15 cores up to 1.7GHz, and four Cortex A7 cores up to 1.3GHz, with full support for HMP/GTS. Contrary to initial reports the new processor is not based on Mali-T624 (as shown in Antutu), but according to Samsung Exynos 5 Hexa page, it will instead use Mali-T628 just like in Exynos 5420 and 5422. This processor could end up with the best price/power consumption/peak performance combo, as few application are able to use more than 2 cores. The SoC also features an embedded Display Port (eDP) interface, and with a memory bandwidth up to 12.8GB/s, supports supports WQXGA (2560×1600) resolution. Exynos 5 Hexa’s video codec supports 1080p 60fps encoding and decoding of H.264, MPEG4, VP8, and more.

Exynos 5422 appears to be a update to Exynos 5420 octacore SoC, with four Cortex A15 core clocked at up to 2.1GHz, and four Cortex A7 cores clocked at up to 1.5GHz. The GPU is still Mali-T628, and the processor also supports HMP. One key difference with Exynos 5260 is that it supports 4K hardware video decoding, albeit outputted to a display up to WQXGA (2560 x 1600) resolution. It’s quite likely Exynos 5422 will be the processor running in the Exynos version of the Galaxy S5Exynos 5422 page on Samsung website has with very few details at this time.

AllWinner UltraOcta A80 big.LITTLE SoC Officially Announced, Includes PowerVR G6230 GPU

February 24th, 2014 9 comments

Allwinner has formally announced AllWinner UltraOcta A80 SoC at Mobile World Congress 2014. The SoC featurs four Cortex A15 and four Cortex A7 cores in big.LITTLE configuration as well as Imagination Technologies PowerVR G6230 GPU, and a VPU with H.265 and VP9 support. The processor will be used in tablets, OTT media players, notebook PCs, all-in-ones, and smart TVs.

Allwinner_A80_Block_Diagram_no_VP9

AllWinner UltraOcta A80 Block Diagram (Updated without VP9)

Key Features:

  • Ultra low power, high performance 28nm UltraOcta SoC with heterogeneous eight-core CPU computing
  • Ultra performance graphics – PowerVR G6230 GPU with two shader clusters and 64 FP32 ALU cores
  • CoolFlex power management system – optimized big.LITTLE technology to dynamically activate energy-efficient or high performance processor cores based on computing workload
  • Next generation video engine – 4K encode/decode, H.265, VP9
  • Triple-screen display support

Imagination PowerVR G6230 Rogue GPU is said to embed power saving technologies such as PVRTC and PVRTC2 texture compression formats, PVRIC (lossless image compression)  and PVRGC (lossless geometry compression). It supports OpenGL ES Next/3.0/2.0, OpenGL 3.x, DirectX 9_3/10, OpenCL and Renderscript APIs.

The press release appears to have been puit out mainly to describe features of PowerVR 6230 GPU, and details about peripherals are still missing, although we can see AllWinner A80 features MIPI, USB host, HDMI and an audio subsystems.

Beside AllWinner PR, you can also read more about the GPU in AllWinner A80 on Imagination Tech blog.

Samsung Exynos 5260 Hexa Core Cortex A15/A7 big.LITTLE Processor

February 20th, 2014 8 comments

Samsung has been teasing with “Exynos Infinity” before Mobile World Congress 2014, and many expect the Korean company to announce their 64-bit mobile processor (Exynos 6 ?). But it’s likely another Exynos SoC will (also) be announced, as a quick search shows recent patch submissions for Exynos 5260, which happens to be an hexa-core processor using two ARM Cortex A15 cores @ 1.7 GHz, and four ARM Cortex A7 cores @ 1.3 Ghz in big.LITTLE configuration supporting HMP (Heterogenous Multi Processing) / GTS (Global Task Scheduling). The official name might be something like Exynos 5 Hexa (5260).

Exynos5260_patchThere’s also a device tree file for Samsung XYREF5260 EVT0 development board.

It would probably be possible to go through the patches to find out more, but there’s an easier solution, and some blogs have already posted details about a leak showing Exynos 5260 used in the upcoming Galaxy Note3 Neo, where we learn the GPU is an ARM Mali-T624. The mobile phone itself boasts a 5.5″ display @ 1280×720, 2GB RAM< 16Gb Flash, an 8MP rear camera and 2.1 MP front camera, and a 3,100 mAh battery. Reports indicate Android 4.3 is currently running on the device, but that it should be eventually be upgraded to 4.4.

The phone gets 29,3282 points in Antutu 4.x, just below Samsung Galaxy Note 3 powered by the more powerful Exynos 5 Octa 5420 or Snapdradong 800.
