Acer is introducing a new 7-inch tablet due for release in June. The upcoming Iconia One 7 is an Intel-powered tablet running Google's Android 4.2 operating system. It is a budget device that cuts corners on the operating system and hardware so that it can reach a starting price of $129.99.
The Iconia One 7 tablet will be available in black, blue, red, pink, and white, and features a 7-inch IPS display with a 16:10 resolution of 1280x800, a 5 megapixel rear camera, and a 0.3 megapixel webcam. The tablet has rounded corners and edges (especially on the back panel).
Internally, Acer has chosen to use a dual core SoC based on Intel's previous generation Clover Trail+ architecture (2-wide, in order cores that support Hyper Threading). The chip features two CPU cores clocked at 1.6 GHz, 1 MB of cache, and a PowerVR SGX544 GPU. THe chip is paired with 1GB of system RAM and either 8GB or 16GB of internal flash storage. The internal storage can be expanded with up to a 32GB microSD card. The tablet is powered by a 3,700 mAh battery.
The tablet hardware is reportedly compatible with Android 4.4, but Acer has yet to outline an upgrade path.
Acer has obviously cut corners here, both on the hardware and software. However, these sacrifices have allowed the company to offer up a tablet at a base price of $129.99. It will not be the fastest device, but it should be a good-enough web browsing and reading tablet for those that prefer the portable 7-inch form factor. (Personally, I would have liked to see a Bay Trail-powered variant at a slightly higher price point.) The Iconia One 7 will be available in Africa, Europe, and the Middle East by the middle of this month and will hit US shores in June.

Tagged: Intel, clover trail, Bay Trail, arm, Android
While we are still waiting for those mysterious Intel Bay Trail based Android tablets to find their way into our hands, we met with ARM today to discuss quite few varying topics. One of them centered around the cost of binary translation - the requirement to convert application code compiled for one architecture and running it after conversion on a different architecture. In this case, running native ARMv7 Android applications on an x86 platform like Bay Trail from Intel.
Based on results presented by ARM, so take everything here in that light, more than 50% of the top 250 applications in the Android Play Store require binary translation to run. 23-30% have been compiled to x86 natively, 20-21% run through Dalvik and the rest have more severe compatibility concerns. That paints a picture of the current state of Android apps and the environment in which Intel is working while attempting to release Android tablets this spring.
Performance of these binary translated applications will be lower than they would be natively, as you would expect, but to what degree? These results, again gathered by ARM, show a 20-40% performance drop in games like Riptide GP2 and Minecraft while also increasing "jank" - a measure of smoothness and stutter found with variances in frame rates. These are applications that exist in a native mode but were tricked into running through binary conversion as well. The insinuation is that we can now forecast what the performance penalty is for applications that don't have a natively compiled version and are forced to run in translation mode.
The result of this is lower battery life as it requires the CPU to draw more power to keep the experience close to nominal. While gaming on battery, which most people do with items like the Galaxy Tab 3 used for testing, a 20-35% decrease in game time will hurt Intel's ability to stand up to the best ARM designs on the market.
Other downsides to this binary translation include longer load times for applications, lower frame rates and longer execution time. Of course, the Galaxy Tab 3 10.1 is based on Intel's Atom Z2560 SoC, a somewhat older Clover Trail+ design. That is the most modern currently available Android platform from Intel as we are still awaiting Bay Trail units. This also explains why ARM did not do any direct performance comparisons to any devices from its partners. All of these results were comparing Intel in its two execution modes: native and translated.
Without a platform based on Bay Trail to look at and test, we of course have to use the results that ARM presented as a placeholder at best. It is possible that Intel's performance is high enough with Silvermont that it makes up for these binary translation headaches for as long as necessary to see x86 more ubiquitous. And in fairness, we have seen many demonstrations from Intel directly that show the advantage of performance and power efficiency going in the other direction - in Intel's favor. This kind of debate requires some more in-person analysis with hardware in our hands soon and with a larger collection of popular applications.
More from our visit with ARM soon!

Back during CES we saw several teasers showing off the MSI GS70 STEALTH gaming laptop and now we finally have a review thanks to Hardware Secrets. The insane specs of this machine mean that the power cord is rated at 120W although at a hair under 6lbs it is surprisingly light. If you can afford the price tag this is a serious contender for the most powerful gaming laptop currently available, barring some that have opted for SLI graphics.
"The MSI GS70 STEALTH is a gaming laptop computer with a fourth-generation Core i7-4700HQ processor, 16 GiB of RAM, 17" Full HD screen, two SSD units in RAID 0, a GeForce GTX 765M video card, high-end Gigabit Ethernet and Wi-Fi controllers, and much more. Let's analyze this powerful machine."

VR-Zone is claiming that this is the successor to NVIDIA's SHIELD portable gaming system. An AnTuTu benchmark was found for a device called, "NVIDIA test model(SHIELD)" with an "NVIDIA Gefroce(Kepler Graphics)" GPU, typos left as-is. My gut expects that it is valid, but I hesitate to vouch the rumor. If it even came from NVIDIA, which the improper spelling and capitalization of "GeForce" calls into question, it could easily be an internal prototype and maybe even incorrectly given the "SHIELD" (which is properly spelled and capitalized) label.
Image Credit: AnTuTu.com
As far as its camera listing, it would make sense for the SHIELD to get one at standard definition (0.3MP -- probably 640x480). The fact that the original SHIELD shipped without any, at all, still confuses me. The low resolution sensor still does not make sense, seeming like an almost pointless upgrade, but it could be used by NVIDIA for a specific application or built-in purpose.
Or, it could be an irrelevant benchmark listing.
Either way, there are rumors floating around about a SHIELD 2 being announced at E3 in June. It is unlikely that NVIDIA will give up on the handheld any time soon. Whether that means new hardware, versus more software updates, is anyone's guess. The Tegra K1 would have been a good launching SoC for the SHIELD, however, with its full OpenGL 4.4 and compute support (the hardware supports up to OpenCL 1.2 although driver support will apparently be "based on customer needs". PDF - page 8).
Waiting. Seeing. You know the drill.

Tagged: unreal engine 4, ue4, epic games
Epic Games has just incremented the minor version number of their popular engine by releasing Unreal Engine 4.1 to all subscribers. While the dot-zero was available privately for quite some time, it was made public barely a month ago. Its headlining feature is a few extra platforms: Linux, SteamOS, Xbox One, and Playstation 4. Each of these are included in the 19$ per month and 5-percent royalty agreement -- excluding outside fees, such as those required to become a registered developer with Sony and/or Microsoft, obviously.
You will also need a capable Windows PC to deploy a game to Playstation 4, Xbox One, Linux, or SteamOS... "for now". This implies that development on other platforms is being considered. Development from OSX seems likely, as does Linux, but creating games on an Xbox One or Playstation 4 seems a bit far-fetched. Who knows though? If any company has good enough relationships with Sony and Microsoft to make it happen, it would be Epic.
— Ray Davis (@EpicRayD) April 25, 2014
I am guessing... Dreamcast support is a "no". It was not that ahead-of-the-curve.
The actual update notes are just shy of 7000 words and about 20 pages long, so platforms are not everything. Epic has been adding a lot of content and templates to the engine and their marketplace, including the Elemental demo first seen at E3 2012. The editor was also updated with numerous improvements, such as better FBX importing (FBX is a cross-application 3d file format).
Also, it is available now.

Tagged: canonical, ubuntu, ubuntu 14.04
Ubuntu, the popular Linux distribution, has been on a steady six-month release schedule for eight years. Every four versions, that is, once every two years, one is marked as Long Term Support (LTS). While typical (non-LTS) releases are supported for around 9 months, LTS versions are provided with five years of updates. Of course, each version, LTS or not, is free. The choice to stay on a specific branch is something else entirely.
For most home users, it will probably make sense to pick up the latest version available on your update manager. Of course, each new release will change things and that can be a problem for some users. That said, given that releases come in six-month intervals, it does make sense to keep up with the changes as they happen, rather than fall behind and have a real shock in five years. Enterprise customers, on the other hand, would love to adopt an operating system which never changes, outside of security updates. Windows XP is a recent example of where enterprise customers will actually pay to not upgrade. These customers will benefit most from LTS.
First and foremost, Canonical, the company behind Ubuntu, wants to catch the wave of PC users who are looking to upgrade from Windows XP and Windows 7. It is free, it has a web browser and an office suite, it is stable and secure, and they suggest that it will be easy to deploy and manage for governments and other institutions.
The interface is Unity7, although users will have the option to try Unity8. The latter version is Canonical's attempt to cover all form factors: phones, tablets, TVs, and desktops.
They probably could have chosen a different number, if only for the jokes.
Ubuntu 14.04 LTS is available now at their website. It is free. If you want it, go get it unless you already have it.

Tagged: Intel, silvermont, arm, quarterly earnings, quarterly results
Sean Hollister at The Verge reported on Intel's recent quarterly report. Their chosen headline focuses on the significant losses incurred from the Mobile and Communications Group, the division responsible for tablet SoCs and 3G/4G modems. Its revenue dropped 52%, since last quarter, and its losses increased about 6%. Intel is still making plenty of money, with $12.291 billion USD in profits for 2013, but that is in spite of Mobile and Communications losing $3.148 billion over the same time.
Intel did have some wins, however. The Internet of Things Group is quite profitable, with $123 million USD of income from $482 million of revenue. They also had a better March quarter than the prior year, up a few hundred million in both revenue and profits. Also, Mobile and Communications should have a positive impact on the rest of the company. The Silvermont architecture, for instance, will eventually form the basis for 2015's Xeon Phi processors and co-processors.
It is concerning that Internet of Things has over twice the sales of Mobile but I hesitate to make any judgments. From my position, it is very difficult to see whether or not this trend follows Intel's projections. We simply do not know whether the division, time and time again, fails to meet expectations or whether Intel is just intentionally being very aggressive to position itself better in the future. I would shrug off the latter but, obviously, the former would be a serious concern.
The best thing for us to do is to keep an eye on their upcoming roadmaps and compare them to early projections.

There is a lot to like about this particular 13.3" ASUS Zenbook, perhaps the most noticeable is the IPS display with a 2560 x 1440 resolution and a capacitive display capable of tracking 10 contact points. There is another reason to fall in love with this notebook, it can run Ubuntu with all of the features enabled without any extra work required. The specifications under the hood are rather impressive as well, a Core-i7 4558U with Intel Iris Graphics 5100, 8GB of DDR3-1600 and two 128GB SSDs capable of supporting RAID. Those of you looking for a powerful notebook which does not require Windows to run properly would be wise to read this review at Phoronix.
"As I wrote about at the beginning of March, I bought the ASUS Zenbook UX301LA-DH71T Haswell-based ultrabook to replace an Apple Retina MacBook Pro as my main system. I've been using this latest Zenbook with Intel Iris Graphics and dual SSDs for several weeks now as my main system and have taken it on four business trips so far and it's been running great. Paired with Ubuntu 14.04 LTS, the ASUS Zenbook UX301LA makes a rather nice lightweight yet powerful Linux system."

Tagged: SoC, snapdragon, qualcomm, LTE, ARMv8, adreno, 64-bit
Qualcomm has announced two new flagship 64-bit SoCs with the Snapdragon 808 and Snapdragon 810. The new chips will begin sampling later this year and should start showing up in high end smartphones towards the second half of 2015. The new 800-series parts join the previously announced mid-range Snapdragon 610 and 615 which are also 64-bit ARMv8 parts.
The Snapdragon 810 is Qualcomm's new flagship processor. The chip features four ARM Cortex A57 cores and four Cortex A53 cores in a big.LITTLE configuration, an Adreno 430 GPU, and support for Category 6 LTE (up to 300 Mbps downloads) and LPDDR4 memory. This flagship part uses the 64-bit ARMv8 ISA. The new Adreno 430 GPU integrated in the SoC is reportedly 30% faster than the Adreno 420 GPU in the Snapdragon 805 processor.
In addition to the flagship part, Qualcomm is also releasing the Snapdragon 808 which pairs two Cortex A57 CPU cores and four Cortex A53 CPU cores in a big.LITTLE configuration with an Adreno 418 (approximately 20% faster than the popular Adreno 320) GPU. This chip supports LPDDR3 memory and Qualcomm's new Category 6 LTE modem.
Both the 808 and 810 have Adreno GPUs which support OpenGL ES 3.1. The new chips support a slew of wireless I/O including Categrory 6 LTE, 802.11ac Wi-Fi, Bluetooth 4.1, and NFC.
Qualcomm is reportedly planning to produce these SoCs on a 20nm process. For reference, the mid-range 64-bit Snapdragon 610 and 615 use a 28nm LP manufacturing process. The new 20nm process (presumably from TSMC) should enable improved battery life and clockspeed headroom on the flagship parts. Exactly how big the mentioned gains will be will depend on the specific manufacturing process, with smaller gains from a bulk/planar process shrink or greater improvements coming from more advanced methods such as FD-SOI if the new chip on a 20nm process is the same transistor count as one on a 28nm process (which is being used in existing chips).
The 808 and 810 parts are the new high-end 64-bit chips which will effectively supplant the 32-bit Snapdragon 805 which is a marginal update over the Snapdragon 800. The naming conventions and product lineups are getting a bit crazy here, but suffice it to say that the 808 and 810 are the effective successors to the 800 while the 805 is a stop-gap upgrade while Qualcomm moves to 64-bit ARMv8 and secures manufacturing for the new chips which should be slightly faster CPU-wise, notably faster GPU-wise and more capable with the faster cellular modem support and 64-bit ISA support.
For those wondering, the press release also states that the company is still working on development of its custom 64-bit Krait CPU architecture. However, it does not appear that 64-bit Krait will be ready by the first half of 2015, which is why Qualcomm has opted to use ARM's Cortex A57 and A53 cores in its upcoming flagship 808 and 810 SoCs.

Today, Lenovo announced a refreshed lineup of its A-series tablets including the A7-50, A8, and A10. The new tablets take a common hardware platform and scale it from a 7-inch tablet to a 10-inch tablet with optional keyboard. All three tablets run the Android 4.2 operating system and will be available in May.
The Lenovo TAB A7-50 Android 4.2 tablet.
The new Lenovo TAB A-series is powered by a quad core MediaTek 8121 SoC clocked at 1.3 GHz paired with 1GB of LP-DDR2 memory and 16GB of internal flash storage. Users can add an additional 32GB of storage with a micro SD card. Networking is handled by an 802.11 b/g/n Wi-Fi and Bluetooth 4.0 radio along with an optional SIM card slot on certain models (cellular functionality not available in the North American market). The tablets come with IPS touchscreens with a resolution of 1280 x 800. Lenovo includes a 2MP webcam and a 5MP rear facing camera on all three A-series tablets. The A10 further adds stereo speakers and compatibility with a keyboard dock.
Lenovo rates all three tablets at eight hours of battery life.
The Lenovo TAB A8 tablet.
Beyond the Lenovo TAB A10 being available with a Bluetooth keyboard dock, the only major differences between the new three A-series tablets are physical dimensions, screen size, and weight. The Lenovo TAB A7-50 measures 198x121.2x9.9mm and weighs 0.70 lbs. The TAB A8 meanwhile measures 217x136x8.9mm and weighs slightly more at 0.79 lbs. Finally, the TAB A10 measures 264x176.5x8.9mm and weighs 1.2 lbs.
The Lenovo TAB A10 with its Bluetooth keyboard dock.
The 7-inch Lenovo Tab A7-50 has an MSRP of $129 while the 8-Inch Tab A8 has an MSRP of $179. The 10.1-inch Tab A10 has a base price of $249 and is also available as a tablet and keyboard bundle for $299.
What do you think about Lenovo's new A-series lineup? On one hand, you have three size options at competitive prices, but on the other you only have a single option as far as internal specifications and screen resolution no matter the screen size. If you can live with the MTK 8121 and 1GB of RAM, they could be a viable option.
