Samsung is bringing a new Chromebook to market next month. Coming in 11-inch and 13-inch form factors the new Samsung Chromebook 2 offers updated hardware and more than eight hours of battery life.
The Chromebook 2 will be available in 11.6” and 13.3” models. The smaller variant will come in white or black while the larger SKU is only available in gray. The lids use a soft touch plastic that resembles stitched leather like that found on some Samsung smartphones. The 11.6” is 0.66-inches thick and weighs 2.43 pounds. The 13.3” model is 0.65-inches thick and weighs 3.09 pounds. The 11.6” Chromebook 2 has a 1366x768 display while the 13.3” Chromebook uses a 1920 x 1080 resolution display.
Internally, the Chromebook 2 is powered by an unspecified Exynos 5 Octa SoC at either 1.9GHz (11.6”) or 2.1GHz (13.3”), 4GB of DDR3L memory, and 16GB internal SSD storage. Internal radios include 802.11ac Wi-Fi and Bluetooth 4.0. Samsung rates the battery life at 8 hours for the 11.6” Chromebook and 8.5 hours for the 13.3” Chromebook.
Beyond the wireless tech, I/O includes one USB 3.0 port, one USB 2.0 port, one HDMI, one headphone output, and one micro SD card slot. This port configuration is available on both Chromebook 2 sizes.
Samsung is launching its Chromebook 2 in April at $319.99 and $399.99 for the 11.6” and 13.3” respectively. This new Chromebook is coming to a competitive market that is increasingly packed with Bay Trail-powered Windows 8.1 notebooks (and tablets) that are getting cheaper and Android tablets that are getting more features and more powerful thanks to new ARM-based SoCs. I'm interested to see what platform users start gravitating towards, is the cloud-connected Chrome OS good enough when paired with good battery life and a physical keyboard?
Are you looking forward to Samsung's new Chromebook 2?

Samsung recently announced two new 32-bit Exynos 5 processors with the eight core Exynos 5 Octa 5422 and six core Exynos 5 Hexa 5260. Both SoCs utilize a combination of ARM Cortex-A7 and Cortex-A15 CPU cores along with ARM's Mali graphics. Unlike the previous Exynos 5 chips, the upcoming processors utilize a big.LITTLE configuration variant called big.LITTLE MP that allows all CPU cores to be used simultaneously. Samsung continues to use a 28nm process node, and the SoCs should be available for use in smartphones and tablets immediately.
The Samsung Exynos 5 Octa 5422 offers up eight CPU cores and an ARM Mali T628 MP6 GPU. The CPU configuration consists of four Cortex-A15 cores clocked at 2.1GHz and four Cortex-A7 cores clocked at 1.5GHz. Devices using this chip will be able to tap up to all eight cores at the same time for demanding workloads, allowing the device to complete the computations and return to a lower-power or sleep state sooner. Devices using previous generation Exynos chips were faced with an either-or scenario when it came to using the A15 or A7 groups of cores, but the big.LITTLE MP configuration opens up new possibilites.
While the Octa 5422 occupies the new high end for the lineup, the Exynos 5 Hexa 5260 is a new midrange chip that is the first six core Exynos product. This chip uses an as-yet-unnamed ARM Mali GPU along with six ARM cores. The configuration on this SoC is four low power Cortex-A7 cores clocked at 1.3GHz paired with two Cortex-A15 cores clocked at 1.7GHz. Devices can use all six cores at a time or more selectively. The Hexa 5260 offers up two higher powered cores for single threaded performance along with four power sipping cores for running background tasks and parallel workloads.
The new chips offer up access to more cores for more performance at the cost of higher power draw. While the additional cores may seem like overkill for checking email and surfing the web, the additional power can enable things like onboard voice recognition, machine vision, faster photo filtering and editing, and other parallel-friendly tasks. Notably, the GPU should be able to assist with some of this parallel processing, but GPGPU is still relatively new whereas developers have had much more time to familiarize themselves with and optimize applications for multiple CPU threads. Yes, the increasing number of cores lends itself well to marketing, but that does not preclude them from having real world performance benefits and application possibilities. As such, I'm interested to see what these chips can do and what developers are able to wring out of them.

On a post from the official ARM blogs, the guns are blazing in the battle for the wearable market mind share. Pretty much all the currently available wearable computing devices are using ARM-based processors but that hasn't prevented Intel from touting its Quark platform as the best platform for wearables. There are still lots of questions about Quark when it comes to performance and power consumption but ARM decided to pit its focus on heat.
For a blog post on ARM's website:
Intel’s Quark is an example that has a relatively low level of integration, but has still been positioned as a solution for wearables. Fine you may think, there are plenty of ARM powered communication chipsets it could be paired with, but a quick examination of the development board brings the applicability further into question. Quark runs at a rather surprising, and sizzling to the touch, 57°C. The one attribute it does offer is a cognitive awareness, not through any hardware integration suitable for the wearable market, but from the inbuilt thermal management hardware (complete with example code), which in the attached video you can see is being used to toggle a light switch once touched by a finger which, acting as a heat sync, drops the temperature below 50°C.
Along with this post is a YouTube video that shows this temperature testing taking place.
Of course, when looking at competitive analysis between companies you should always take the results as tentative at best. There is likely to be some change between the Quark Adruino board (Galileo) integration of the X1000 and what would make it into a final production wearable device. Obviously this is something Intel is award of as well and they are also aware of what temperature means for devices that users will have such direct contact with.
The proof will be easy to see, either way, as we progress through 2014. Will device manufacturers integrated Quark in any final design wins and what will the user experience of those units be like?
Still, it's always interesting to see marketing battles heat up between these types of computing giants.

Tagged: mediatek, arm, cortex, A17
Our Josh Walrath wrote up an editorial about the Cortex-A17 architecture less than two days ago. In it, he reports on ARM's announcement that "the IP" will ship in 2015. On the same calendar date, MediaTek announced their MT6595 SoC, integrating A17 and A7 cores, will be commercially available in 1H 2014 with devices in 2H 2014.
Of course, it is difficult to tell how ahead of schedule this is, depending on what ARM meant by shipping in 2015 and what MediaTek meant by devices based on the MT6595 platform in 2H 2014.
There are two key features about the A17: a 40% power reduction from A15 and its ability to integrate with A7 cores in a big.LITTLE structure. MediaTek goes a little further with "CorePilot", which schedules tasks across all eight cores (despite it being a grouping of two different architectures). This makes some amount of sense because it allows for four strong threads which can be augmented with four weaker threads. Especially for applications like web browsers, it is not uncommon to have a dominant main thread.
The SoC will also support LTE and HSPA+ mobile and 802.11ac wireless connections. It will not integrate the Mali-T720 GPU (DX11/OpenGL ES 3.0), but instead use the Power VR Series6 GPU (DX10/OpenGL ES 3.0 unless it is an unannounced design). MediaTek does not explain why they chose the one licensed GPU over the other.
MediaTek claims the MT6595 platform will be available in the first half of 2014 with devices coming in the second half.

The Inquirer had a chance to hear more about the upcoming Opteron A111 which contains an ARM Cortex A57. We now know it runs at 2GHz, can address up to 128GB of RAM and has enough channels for 8 drives to be connected to it. While the chips will be able to operate in tandem with traditional x86 server chips the reduction in power needed and heat produced could mean Opteron based servers could be as small as a cellphone. We also know that they will be running on a specially flavoured version of Fedora, read on to see what else was revealed by Ian Drew.
"CHIP DESIGNER AMD has spilled some more details about its first ARM based server processor."

The Inquirer had a chance to talk to Lakshmi Mandyam, the director of Server Systems and Ecosystems at ARM, about their plans for the server room. ARM and their SBSA team have joined forces with Microsoft's Open Technology initiative which is key to AMD's adoption of ARM architecture in their new Opteron series. These projects will offer several key benefits to customers, the open source nature will allow customization in the server room for those customers with specific needs and the know how to implement them and the nature of ARM processors can bring energy bills down. This could also be great news for smaller businesses that require a proper server, they will be able to build that server out of a number of inexpensive ARM based processors instead of having to spend the price of the currently available x86/64 CPUs from Intel and AMD.
"CHIP DESIGNER ARM announced at the Open Compute Project (OCP) Summit last week that servers based on its architecture have taken a step forward with the arrival of ARM v8-A based 64bit servers, known as the Server Base System Architecture (SBSA) specification."

The Opteron A1100 will be the name born by AMD's first SoC, which we knew previously as Seattle and is the first chip which will contain ARM Cortex A57 architecture working in tandem with AMDs. It will be a full 64bit chip and will sport up to 4MB of shared L2 cache and 8MB of shared L3 cache and it will support of to four DIMMs of either DDR3 or DDR4 in dual channel with ECC. It will boot using UEFI into a Linux environment based on Fedora and will be optimized to handle web front ends and data centre tasks. As far as connectivity it will have 8 lanes of PCIe 3.0 and 8 SATA 3 ports. You can follow links from The Register to see the AMD Press Release.
"CHIP DESIGNER AMD is preparing to sample its 64-bit ARM based server processors codenamed Seattle, which will be the company's first stab at a system on chip (SoC) design for data centre products."

Lenovo introduces a unique form factor
Lenovo isn't a company that seems interested in slowing down. Just when you think the world of notebooks is getting boring, it releases products like the ThinkPad Tablet 2 and the Yoga 2 Pro. Today we are looking at another innovative product from Lenovo, the Yoga Tablet 8 and Yoga Tablet 10. While the tablets share the Yoga branding seen in recent convertible notebooks these are NOT Windows-based PCs - something that I fear some consumers might get confused by.
Instead this tablet pair is based on Android (4.2.2 at this point) which brings with it several advantages. First, the battery life is impressive, particularly with the 8-in version that clocked in more than 17 hours in our web browsing test! Second, the form factor of these units is truly unique and not only allows for larger batteries but also a more comfortable in-the-hand feeling than I have had with any other tablet.
Check out the video overview below!
You can pick up the 8-in version of the Lenovo Yoga Tablet for just $199 while the 10.1-in model starts at $274.
The Lenovo Yoga Tablet is available in both 8-in and 10.1-in sizes though the hardware is mostly identical between both units include screen resolution (1280x800) and SoC hardware (MediaTek quad-core Cortex-A7). The larger model does get an 8000 mAh battery (over the 6000 mAh on the 8-in) but isn't enough to counter balance the power draw of the larger screen.
The 1280x800 resolution is a bit lower than I would like but is perfectly acceptable on the 8-in version of the Yoga Tablet. On the 10-in model though the pixels are just too big and image quality suffers. These are currently running Android 4.2.2 which is fine, but hopefully we'll see some updates from Lenovo to more current Android versions.
