Tagged: oculus rift, Oculus
The current Oculus Rift development kit will being to sell out, region-by-region, as their current inventory depletes. This is because "certain components" which they require are no longer available nor will they be produced. They claim to be looking for alternate suppliers but do not know how long that will take. In case you are wondering, they will be floating a stash of units to fulfill replacement requests (RMAs).
As of five days ago, they currently have stock in the following regions:
- United States
- European Union
- South Korea
Of course, there is now speculation that Oculus is preparing to launch a new development kit revision. It is obvious that something new is in the works, especially since they presented a prototype at this year's CES, less than two months ago. The cynical way to take this is that they are looking to deplete their stock before releasing a new unit. The other direction is that they were intending to sell the first kit for a little while longer but one or two parts became difficult to acquire. Either way, unless finding a replacement source is easy enough and they do resume production of the original kit, we might be seeing a refresh at some point.
The question is then, "How long will that take?"

Not content with selling phones and hotspots, Verizon combined both into a phablet called the Ellipsis 7 4G LTE tablet. It features a 1280x800 7" HD IPS display and runs Android 4.2.2 on an quad-core ARM Cortex A7 @ 1.2GHz with 1GB of RAM. At $120 with a 2 year contract, plus connectivity charges of course, it is not a bad price for an LTE capable tablet and even the $300 price tag without a contract beats the price of many phones on the market. Of course price is not everything, which is why you should check out Legit Reviews full coverage of the tablet here.
"The Verizon Ellipsis 7 Tablet is a new release from 'The Worlds Most Reliable Network'. The Ellipsis 7 is targeted at those looking for productivity on the go, as well as a touch of entertainment. A 7" tablet is small enough to toss into a jacket pocket or purse, but large enough to use for most tasks without an issue.

When we were testing the ORIGIN PC EON17-SLX gaming notebook over the last few weeks we wanted to try out another component that high end laptop gamers might be interested in: notebook coolers. Obviously with a beast of a machine like the EON17-SLX, we couldn't just go with something you might find on the shelves at Best Buy. Instead, today we have a video overview of the CM Storm SF-17 Gaming Laptop Cooler by Cooler Master.
This cooler includes a 180mm fan, 4-port USB hub and a red LED light bar to give some style to your gaming setup.
You can find the Cooler Master CM Storm SF-17 cooler on Amazon.com for $59.

UPDATE (Feb 26th): Our readers pointed out in the comments, although I have yet to test it, that you can change Origin's install-to directory before installing a game to have them on a separate hard drive as the rest. Not as easy as Steam's method, but apparently works for games like this that you want somewhere else. I figured it would forget games in the old directory, but apparently not.
Well, okay. Titanfall will require a significant amount of hard drive space when it is released in two weeks. Receiving the game digitally will push 21GB of content through your modem and unpack to 48GB. Apparently, the next generation has arrived.
Honestly, I am not upset over this. Yes, this basically ignores customers who install their games to their SSDs. Origin, at the moment, forces all games to be installed in a single directory (albeit that can be anywhere) unlike Steam, which allows games to be individually sent to multiple folders. It would be a good idea to keep those customers in mind... but not at the expense of the game itself. Like always, both "high-end" and "unoptimized" titles have high minimum specifications; we decide which one applies by considering how effectively the performance is used.
That is something that we will need to find out when it launches on March 11th.

You don't often see performance scaling as clean as what Phoronix saw when testing the effect of memory speed on AMD's A10-7850K. Pick any result and you can clearly see a smooth increase in performance from DDR3-800 to DDR3-2400. The only time that increase seems to decline slightly is between DDR3-2133 and 2400MHz, with some tests showing little to no increase between those two speeds. Some tests do still show an improvement, for certain workloads on Linux the extra money is worth it but in other cases you can save a few dollars and limit yourself to the slightly cheaper DDR3-2133. Check out the full review here.
"Earlier in the week I published benchmarks showing AMD Kaveri's DDR3-800MHz through DDR3-2133MHz system memory performance. Those results showed this latest-generation AMD APU craving -- and being able to take advantage of -- high memory frequencies. Many were curious how DDR3-2400MHz would fair with Kaveri so here's some benchmarks as we test out Kingston's HyperX Beast 8GB DDR3-2400MHz memory kit."

AMD released their Catalyst 14.2 Beta V1.3 graphics drivers today, coinciding with the launch of Thief. The game, developed by Eidos Montreal and published by Square Enix, is another entry in "Gaming Evolved" and their "Never Settle" promotion. Soon, it will also support Mantle and TrueAudio.
Being Theif's launch driver, it provides optimizations for both single-GPU and Crossfire customers in that title. It also provides fixes for other titles, especially Battlefield 4 which can now run Mantle with up-to four GPUs. Battlefield 3 and 4 also supports Frame Pacing on very high (greater than 2560x1600) resolution monitors in dual-card Crossfire. It also fixes a couple of bugs in using Crossfire with DirectX 9 games, missing textures Minecraft, and corruption in X-Plane.
Catalyst 14.2 Beta V1.3 driver is available now at AMD's website.

Recently, Intel released the 220.127.116.1112 (18.104.22.168.3412 for 64-bit) drivers for their Ivy Bridge and Haswell integrated graphics. The download was apparently published on January 29th while its patch notes are dated February 22nd. It features expanded support for Intel Quick Sync Video Technology, allowing certain Pentium and Celeron-class processors to access the feature, as well as an alleged increase in OpenGL-based games. Probably the most famous OpenGL title of our time is Minecraft, although I do not know if that specific game will see improvements (and if so, how much).
The new driver enables Quick Sync Video for the following processors:
- Pentium 3558U
- Pentium 3561Y
- Pentium G3220(Unsuffixed/T/TE)
- Pentium G3420(Unsuffixed/T)
- Pentium G3430
- Celeron 2957U
- Celeron 2961Y
- Celeron 2981U
- Celeron G1820(Unsuffixed/T/TE)
- Celeron G1830
Besides the addition for these processors and the OpenGL performance improvements, the driver obviously fixes several bugs in each of its supported OSes. You can download the appropriate drivers from the Intel Download Center.

Tagged: security, nightmare, byod
The new generation of workers arriving on the scene are of a connected generation, fully conformable with technology and ways of sharing; though with neither clue nor care about security. That extends from doing an end run around Sharepoint and sFTP sites in favour of Dropbox and Google Drive, blissfully unaware that the Terms and Service agreement spell out that they now have a copy of your proprietary data for quality assurance purposes thus breaking security agreements made with clients. The software is only a part of the problem as Bring Your Own Device arrives on the scene with your new hires. Benchmark Reviews has put up an overview of what that may mean for many companies and discusses the benefits of implementing true Mobile Device Management software. With proper MDM you can, for the most part, retain some control over the devices connected to your systems, attempting to blacklist the many apps which will happily share any of your company's information stored on the phone and in many cases be able to wipe the device remotely after the inevitable accidental loss of such a device.
MDM's mitigating the problems created by BYOD is good in theory but it overlooks one major issue that this will cause. Your IT staff are now going to be bombarded by requests to fix these random devices, from Microsoft and Apple to Sony and Google through Lenovo and Samsung, every tablet or portable device in every possible configuration of OS and software will show up on your IT peoples desks. Regardless the original official policy, once you accept BYOD your IT people will spend huge amounts of time figuring out basic troubleshooting for devices they've never seen before as you can bet there is no budget to give IT one of each device and time to get familiar with it.
In many cases your techies won't even be able to say with certainty that the device is capable of doing what the user wants in the first place. How will you explain to someone who picked up a Surface that WinRT is not going to be able to be added to the domain for ActiveSync access or that your Samsung just isn't going to connect to that Sharepoint site you do a lot of work on? What will you do when someone hands you a Huawei MediaPad X1? BYOD may attract young new minds to your company but realize that there is a cost to be paid in both lawyers fees when your client discover how much of their data has been accidentally shared as well as in the time your already overworked IT staff have to support your actual infrastructure.
"Let’s face it, smart phones and tablets have become a common part of life. It is not unusual to walk into a place and see a majority of the people with their eyes down, totally engrossed in a mobile device. This is something that happens out in everyday life and is becoming increasingly more common in the workplace. Laptops and desktops are starting to be replaced by tablets and laptop-tablet hybrids. No matter the business industry, just like computers, tablets and smartphones are becoming essential in almost all areas of business."

Introduction and Design
Alongside our T440s review unit was something slightly smaller and dear to our hearts: the latest entry in the ThinkPad X series of notebooks. Seeing as this very review is being typed on a Lenovo X220, our interest was piqued by the latest refinements to the formula. When the X220 was released, the thin-and-light trend was only just beginning to pick up steam leading into what eventually became today’s Ultrabook movement. Its 2012 successor, the ThinkPad X230, went on to receive our coveted (and rarely bestowed) Editor’s Choice Award, even in spite of a highly controversial keyboard change that sent the fanbase into a panic.
But all of that has since (mostly) blown over, primarily thanks to the fact that—in spite of the minor ergonomic adjustments required to accustom oneself with what was once a jarringly different keyboard design—the basic philosophy remained the same: pack as many powerful parts as possible into a 12.5-inch case while still maintaining good durability and battery life. These machines were every bit as capable as most other 13- and 14-inch notebooks of their time, and they were considerably smaller, too. About the only thing they lacked was higher-resolution screens, discrete graphics, and quad-core CPUs.
But with the X240 (and the T440s), portability has truly taken center stage, suggesting a complete paradigm shift—however subtly—away from “powerful (and light)” and toward “light (and powerful)”. Coupled with Intel’s Haswell CPUs and Lenovo’s new Power Bridge dual-battery design, this will certainly yield great benefits in the realm of battery life. But that isn’t all that’s different: we also find a (once again) revamped keyboard, as well as a completely new touchpad design which finally dispenses with the physical buttons entirely. Like in the X230’s case, these changes have roiled the ThinkPad purists—but is it all just a matter of close-minded traditionalism? That’s precisely what we’ll discover today.

Western Digital has several lines of hard disks to choose from. You have Greens, Blues, Blacks, enterprise RE's, and even ones named after dinosaurs. Then came a mix of RE and GP in the form of the RE4-GP. Then came the Red series, which carried some more of the enterprisey features from the RE series over into a NAS-tailored drive that sipped power like a Green. Then there was the AV-GP which took a green and tweaked the firmware to better handle multiple video streams being read to and written from the disk simultaneously.
You'd figure they had every possible angle covered, but apparently there was a hole to fill. Turns out the home / small business surveillance market is a bit of a big deal. We're talking about those security systems you see capturing 16 or even 32 video streams simultaneously. Add the fact that these larger systems tend to store their streams to a RAID as opposed to a single disk. What was needed was a drive capable of handling a greater number of simultaneous streams than an AV-GP, while also carrying over the RAID features of the Red, and doing so without driving costs into the enterprise territory of the SE/RE.
Behold the solution:
The WD Purple is an Advanced Format HDD that is optimized for recording up to 32 HD video streams simultaneously:
Writing 32 separate streams to a hard drive would usually lead to the heads thrashing about, trying to keep up with what appears to be random writes. The Purple has much smarter firmware that has been tuned for this specific purpose (seen above maintaining 50% idle time while handling 32 HD streams). While these firmware optimizations would hurt performance in normal consumer use, for heavy surveillance usage, this is likely the closest you can get to SSD performance for this application - without high cost/GB of using solid state as a solution to such a capacity hungry problem.
Speaking of cost/GB, Purple drives are quite reasonable, starting at $89 for 1TB up to $199 for the flagship 4TB capacity.
Press blast after the break:

Tagged: windows 8, SFF, mintbox, linux, ipc2, haswell, compulab
CompuLab, the company behind the MintBox, launched its small form factor Intense PC 2 last month in four SKUs using Intel's latest Haswell processors. The systems are now available for purchase starting at $388 for the base model. The Intense PC 2 shares a similar form factor to the existing Intense PC and MintBox systems (resembling a consumer router), but features new hardware and IO options.
The Intense PC 2 measures 6.3” x 7.4”x 1.57” and has an aluminum chassis that acts as a passive heatsink for the internal components. The case is dark gray with a finned top surface. The front of the system can be customized with FACE modules that offer different IO options. However, by default the Intense PC 2 has two USB 3.0 ports and three indicator LEDs on the front and the following IO ports on the rear:
- 2 x Gigabit Ethernet ports (Intel NICs)
- 2 x HDMI video outputs
- 1 x DisplayPort video output
- 2 x USB 3.0
- 2 x USB 2.0
- 3 x RS232
- 3 x (2 x analog, 1 x digital S/PDIF)
- 1 x SIM card slot
- 2 x antenna connectors
The FACE modules can expand connectivity to include VGA ouptuts, video capture inputs, additional networking, and additional USB ports (among other options).
Internally, the Intense PC 2 has a small motherboard that comes with an Intel Celeron, i3, i5, or i7 Haswell processor, up to 16GB of DDR3L 1600 MHz memory (two slots), a single mSATA port, and a single mPCIE port (the mSATA port is a combo mSATA/mPCIe port). An 802.11ac+Bluetooth 4.0 radio is included as part of the package. The 15W TDP CPU can be passively cooled, and at the high end you can get up to an Intel Core i7 4600U with HD 4400 graphics. The dual core (plus hyperthreading) chip can turbo up to 3.3 GHz. The table below from the CompuLab specification sheet (PDF) details the hardware layouts of the various IPC2 SKUs.
The Intense PC 2 is aimed at desktop users as well as the industrial sector. The passively cooled mini PC can be easily used as a desktop, home server, router+802.11ac access point, HTPC, or Steambox (streaming endpoint mainly), for example. It is also capable of driving signage and large 4K displays for adversiting and other tasks.
The Intense PC is available in four base SKUs ranging in price from $388 to $902. Adding an SSD and/or pre-installed OS add to that base price. CompuLab offers a 5 year warranty on the SFF system.

Intel, Mediatek and Allwinner have all come out with new SoC announcements at Mobile World Congress and Qualcomm is no different. By far the most interesting release is what it calls the "first commercial" 64-bit Octa-Core chipset with integrated global LTE support. The list of features and technologies included on the chipset is impressive.
The Snapdragon 615 integrates 8 x ARM Cortex-A53 cores that opterate on the newer 64-bit ARMv8 architecture while supporting 32-bit for backwards compatibility. Qualcomm is not using a custom designed CPU core for this chipset but the company has stated it will have its own custom 64-bit core sometime in 2015. This 8-core model is divided into a pair of quad-core clusters that will be tuned to different clock speed and power levels, offering the ability to run slightly more efficiently than would be possible with all cores tuned to the highest performance.
Snapdragon 610 is essentially the same design but is limited to a quad-core, single cluster setup.
Both of these parts will integrate the Qualcomm custom built Adreno 405 GPU that brings a DX11 class feature set, along with OpenGL ES 3.0 and OpenCL 1.2. The Adreno 405 performance is still unknown but it should be able to compete with the likes of PowerVR's Series6 used in the Apple A7 and Intel Merrifield parts. Quad HD resolutions are supported up to 2560x1600 and Miracast integration enables wireless display. H.265 hardware decode acceleration also found its way into the 615/610.
Connectivity features of the Snapdragon 615/610 include 802.11ac wireless as well as the company's 3rd generation LTE modem. Category 4 and carrier aggregation are optional.
Qualcomm has publicly stated that the move to 8-core processors with software lacking the capability to manage them properly was a poor decision. But it would appear that the "core race" has infected just about everyone.

As you might expect from the name, the Antec Kuhler 1250 is a larger version of the popular all in one liquid CPU coolers. This model is designed for overclockers, with a radiator measuring 159mm x 120mm x 27mm which does limit the amount of enclosures it will fit in unless you plan on an external mount. As it is only $10 more than the smaller 950 it comes out ahead on [H]ard|OCP's dollar to performance ratio; at $120 it is a bit of an investment but for overclockers it is a decent solution to heat problems.
"Antec and its All-In-One sealed system CPU coolers have been around for a good while now. We still have some of its first series working well here in the HardOCP offices.

Tagged: ultraocta a80, PowerVR, MWC 14, MWC, big.little, Allwinner
The wheels keep turning from Mobile World Congress 2014 in Barcelona with Allwinner's announcement of the UltraOcta A80 SoC. Dubbed the "world's first big.LITTLE octa-core (8-core) heterogeneous SoC to included PowerVR Series6 GPU technology", the UltraOcta A80 combines four Cortex-A7 and four Cortex-A15 cores in a single chip design.
The UltraOcta A80 is aimed at tablets, portable game consoles, set-top boxes, media players and other devices that require "premium performance" level parts. The first devices will apparently hit "soon" but no other details were offered.
ARM is definitely on-board with Allwinner for this product as it is the poster child example of how the big.LITTLE design philosophy can be implemented to offer both high performance and low power results in one SoC. This chip is built on 28nm process technology and also includes high performance graphics with the PowerVR G6230 GPU. This GPU includes two "clusters" for a total of 64 ALUs (called cores in other SoC). Keep in mind that this Series6 GPU is about half the performance of the G6400 series included in the iPhone 5s and even Intel's new Merrifield and Moorefield processors.
The Allwinner UltraOcta A80 will also support 4K video encode and decode with H.265 thrown in for good measure. I am very curious to see the load on the SoC during these types of high quality video processes as the amount of acceleration on the chip isn't known yet.

Tagged: microsoft, surface, win8
DigiTimes does not specifically mention Surface but there are not too many devices running Windows 8 which can be purchased for under $250. By reducing the licensing fee by $35 for machines that are at that price level Microsoft might make system builders a little more interested to include low cost Windows 8 machines in their lineup as they can sell at a higher margin or at a lower MSRP. Of course consumers would still have to buy them for those companies to make a profit and it seems very unlikely that a 10% price reduction will convince people they need a Surface or similar device when there are so many other alternatives available. It does make you wonder if you could get your hands on a Win8 license at a lower cost if you promise to install it on a cheap system.
"Microsoft plans to further decrease Windows 8.1 licensing rates for entry-level PCs priced below US$250 and tablets, from nearly US$50 currently to about US$15, according to Taiwan-based PC supply chain makers."

Tagged: z3480, PowerVR, MWC 14, MWC, moorefield, merrifield, Intel, atom
Intel also announced an LTE-Advanced modem, the XMM 7260 at Mobile World Congress today.
Last May Intel shared with us details of its new Silvermont architecture, a complete revamp of the Atom brand with an out-of-order design and vastly improved performance per watt. In September we had our first real-hands on with a processor built around Silvermont, code named Bay Trail. The Atom Z37xx and Z36xx products were released and quickly found their way into products like the ASUS T100 convertible notebook. In fact, both the Bay Trail processor and the ASUS T100 took home honors in our end-of-year hardware recognitions.
Today at Mobile World Congress 2014, Intel is officially announcing the Atom Z35xx and Z34xx processors based on the same Silvermont architecture, code named Moorefield and Merrifield respectively. These new processors share the same power efficiency of Bay Trail and excellent performance but have a few changes to showcase.
Though there are many SKUs yet to be revealed for Merrifield and Moorefield, this comparison table gives you a quick idea of how the new Atom Z3480 compares to the previous generation, Atom Z2580 and Clover Trail+.
The Atom Z3480 is a dual core (single module) processor with a clock speed as high as 2.13 GHz. And even though it doesn't have HyperThreading support, the new architecture is definitely faster than the previous product. The cellular radio listed on this table is a separate chip, not integrated into the SoC - at least not yet. PowerVR G6400 quad core/cluster graphics should present performance somewhere near that of the iPhone 5s with support for OpenCL and RenderScript acceleration. Intel claims that this PowerVR architecture will give Merrifield a 2x performance advantages over the graphics system in Clover Trail+. A new image processor allows for 1080p60 video capture (vs 30 FPS before) and support Android 4.4.2 is ready.
Most interestingly, the Merrifield and Moorefield SoCs do not use Intel's HD graphics technology and instead return to the world of Imagination Technology and the PowerVR IP. Specifically, the Merrifield chip, the smaller of the two new offerings from Intel, is using the PowerVR G6400 GPU; the same base technology that powers the A7 SoC from Apple in the iPhone 5s.
A comparison between the Merrifield and Moorefield SoCs reveals the differences between what will likely be targeted smartphone and tablet processors. The Moorefield part uses a pair of modules with a total of four cores, double that of Merrifield, and also includes a slightly higher performance PowerVR GPU option, the G6430.
Intel has provided some performance results of the new Atom Z3480 using a reference phone, though of course, with all vendor provided benchmarks, take them as an estimate until some third parties get a hold of this hardware for independent testing.
Looking at GFXBench 2.7, Intel estimates that Merrifield will run faster than the Apple A7 in the iPhone 5s and just slightly behind the Qualcomm Snapdragon 800 found in the Samsung Galaxy S4. Moorefield, the SoC that adds slightly to GPU performance and doubles the CPU core count, would improve performance to best the Qualcomm result.
WebXPRT is a web application benchmark and with it Intel's Atom Z3480 has the edge over both the Apple A7 and the Qualcomm S800. Intel also states that they can meet these performance claims while also offering better battery life than the Snapdragon S800 as well - interestingly the Apple A7 was left out of those metrics.
Finally, Intel did dive into the potential performance improvements that support for 64-bit technology will offer when Android finally implements support. While Kitkat can run a 64-bit kernel, the user space is not yet supported so benchmarking is a very complicated and limited process. Intel was able to find instances of 16-34% performance improvements from the move to 64-bit on Merrifield. We are still some time from 64-bit Android OS versions but Intel claims they will have full support ready when Google makes the transistion.
Both of these SoCs should be showing up in handsets and tablets by Q2. Intel did have design wins for Clover Trail+ in a couple of larger smartphones but the company has a lot more to prove to really make Silvermont a force in the mobile market.

Intel also announced Merrifield and Moorefield SoCs at Mobile World Congress today.
In 2011, Intel acquired SysDSoft to improve and accelerate the companies transition into the mobile wireless controllers, LTE in particular. As a result, Intel released the XMM 7160 modem in 2013 which included the X-GOLD 716 baseband controller that could support LTE and HSPA functions. This modem was adopted by a handful of OEMs in the market with Cat 4 bandwidth up to 150 Mbps (downstream) and 50 Mbps (upstream), LTE voice implementation and globally capability with 15 bands.
This modem was available as a multi-chip solution for mobile device vendors to implement but was shipped in a M.2 module. The latter form gave a quick option for notebook and tablet vendors to include in ready-built systems.
At Mobile World Congress today though, Intel is announcing its next generation modem, the XMM 7260 LTE-Advanced. As the name implies, this update includes support for LTE-Advanced that adds in features like carrier aggregation and a pair of downlink channels for up to 300 Mbps data rates. Carrier aggregation can be used for additional bandwidth performance or to disperse spectrum in a more efficient way to improve reliability. Intel claims that this controller and modem meets the maximum specification levels of LTE today.
The XMM 7260 LTE-Advanced includes the X-GOLD 726 that is truly a global market ready part with frequency compatibility on LTE FDD/TDD, WCDMA/HSPA+, TD-SCDMA/TD-HSPA/EDGE. This iteration uses fewer components, thus is smaller and easier to integrate than the 7160, and will be "on shelf" as early as next quarter. There is no CDMA support included, though. For users on Verizon and Sprint, we'll have to see if handset makers for those carriers have adjusted their timelines for LTE-only devices. AT&T and T-Mobile, in the US, will have no issues with 4G and 3G support.
This modem is meant to compete directly with the stranglehold that Qualcomm has on the LTE market (and one source tells me that carriers "are dying for an alternative" to help drive down costs). Though it might seem odd in some ways, I fully expect this XMM 7260 modem to be paired with non-Intel SoC devices, including smartphones and tablets. In fact, it is quite possible that the XMM 7260 LTE-Advanced modem might have more successful adoption than the upcoming Merrifield SoCs, also announced today. Device manufacturers might be satisfied with their choice in SoCs, not demanding an alternative in x86, but also might appreciate a new modem.
As a side note, the XMM 7260 is being built on TSMC's 28nm process technology rather than on Intel's own fabs (this isn't the first time it has happened). I don't expect this to be a concern for performance but it is interesting to see a chip that Intel is placing so much emphasis on being constructed outside its own walls.
The XMM 7269 LTE-Advanced modem is currently in certification and is expected to be available for integration in Q2, 2014.

NVIDIA has been teasing the Tegra 4i for quite some time - the integration of a Tegra 4 SoC with the acquired NVIDIA i500 LTE modem technology. In truth, the Tegra 4i is a totally different processor than Tegra 4. While the big-boy Tegra 4 is a 4+1 Cortex-A15 chip with 72 GPU cores, the Tegra 4i is a 4+1 Cortex-A9 design with 60 GPU cores.
NVIDIA and up-and-coming European phone provider Wiko are announcing at Mobile World Congress the first Tegra 4i smartphone: Wax. That's right, the Wiko Wax.
Here is the full information from NVIDIA:
NVIDIA LTE Modem Makes Landfall in Europe, with Launch of Wiko Tegra 4i LTE Smartphone
Wiko Mobile, France’s fastest growing local phonemaker, has just launched Europe’s first Tegra 4i smartphone.
Tegra 4i – our first integrated LTE mobile processor – combines a 60-core GPU and our own LTE modem to bring up to 2X higher performance than competing phone chips.
It helps the Wiko WAX deliver fast web browsing, best-in-class gaming performance, smooth video playback and great battery life.
Launched at Mobile World Congress, in Barcelona, the Wiko WAX phone features a 4.7-inch 720p display, 8MP rear camera and LTE / HSPA+ support.
The phone will be available throughout Europe – including France, Spain, Portugal, Germany, Italy, UK and Belgium – starting in April.
Within two short years, Wiko has become a major player by providing unlocked phones with sophisticated design, outstanding performance and the newest technologies. It has more than two million users in France and is expanding overseas fast.
Wiko WAX comes pre-installed with TegraZone – NVIDIA’s free app that showcases the best games optimized for the Tegra processor.
As a refresher, Tegra 4i includes a quad-core CPU and fifth battery saver core, and a version of the NVIDIA i500 LTE modem optimized for integration.
The result is an extremely power efficient, compact, high-performance mobile processor that unleashes performance and capability usually only available in costly super phones.

Also at Mobile World Congres, Lenovo expanded their smartphone portfolio with three additions. Each of these belong to the S-series, although they are only loosely related to one another. North American readers will probably not be able to purchase them, of course; Lenovo's US and Canada websites do not even have a section for smartphones (products like the Vibe Z can be searched directly - but are not available). I take that as a sign.
Anyway, the three phones belong to the S-series but each has a distinct customer in mind. The S860 seems to picture a business user who travels and wants to talk for long periods of time between charges. The similarly named S850 cuts back on RAM and charge capacity, replacing it with aesthetics (colors and an all-glass exterior) and a slightly lower price for users looking for design. Finally, the S660 is the lowest-price of the three, sacrificing things like camera, storage, and screen resolution for users who do not care about any of that.
Let us compare the three phones in a table.
|Display||5.3" 720p||5" 720p||4.7" 960x540|
|Processor (SoC)||MediaTek Quad-Core, 1.3 GHz|
|Dual SIM Card||Yes|
All three phones will be available this year, either at retail or on Lenovo's website. The Lenovo S860 is expected to retail for $349, the S850 should be $269, and the S660 comes in at $229.
