Have you ever wondered how a mobile GPU is born? Or how the architecture of a mobile GPU like ARM Mali differs from the technology in your discrete PC graphics card? Perhaps you just want to know if ideas like HBM (high bandwidth memory) are going to find their way into the mobile ecosystem any time soon?
Josh and I sat down (virtually) with ARM's VP of Technology and Fellow, Jem Davies, to answer these questions and quite a bit more. The resulting interview will shed light on the design process of a mobile GPU, how you get the most out of an SoC that measures power by the milliwatt, what the world of mobile benchmarking needs to do to clean up its act and quite a bit more.
You'd be hard pressed to find a better way to spend the next hour of your day as you will without a doubt walk away more informed about the world of smartphones, tablets and GPUs.

The new Dell Venue 11 Pro is a tablet with a 10.8" touchscreen with 10 point capacitive touch displaying at a 1080p resolution powered by the Intel HD5300 present on the CoreM 5Y71 processor. That processor has a base frequency of 1.2GHz and a much more impressive maximum boost of 2.9GHz, offering both power savings and powerful performance depending on the needs of the application you are using. 8GB of DDR3-1600MHz will help you use many applications and the 256GB SSD is a nice touch for those who prefer to have most of their software and data stored locally.
"If you are looking for a professional looking convertible with the latest available low power consumption Intel Core M processor which is paired with 8GB of RAM, 256GB SSD and comes with a fully-fledged Windows 8.1 Pro operating system, then look no further, your answer is here!"

The physical difference between the Galaxy S6 and the Galaxy S6 Edge are quite visible, but does the different body justify the price difference? The curved screen adds a bit of screen real estate and provides improved view angles compared to the base model but similar to the previous Galaxy Note Edge, there are not many apps designed to take advantage of the curve. The phone is 7mm thick and weighs slightly less than the base S6 at 132g, with a similar battery and the same TouchWiz overlay on top of Android Lollipop. You can check out what The Inquirer thought of Samsung's new premium phone here if you are considering purchasing the S6 Edge.
"THE GALAXY S6 EDGE will be seen by many as an expensive gimmick given that it's over £100 more expensive than the regular Galaxy S6, while others will see it as Samsung pushing the boundaries of design, and trumping its rivals by bringing something new to the smartphone market."

When I first was handed the Intel Compute Stick product at CES back in January, my mind began to race with a lot of questions. The first set were centered around the capabilities of the device itself: where could it be used, how much performance could Intel pack into it and just how many users would be interested in a product like this? Another set of questions was much more philosophical in nature: why was Intel going in this direction, does this mean an end for the emphasis on high performance componentry from Intel and who comes up with these darned part numbers?
I have since settled my mind on the issues surrounding Intel’s purpose with the Compute Stick and began to dive into the product itself. On the surface the Intel Compute Stick is a product entering late into a potentially crowded market. We already have devices like the Roku, Google Chromecast, the Apple TV, and even the Amazon Fire TV Stick. All of those devices share some of the targets and goals of the Compute Stick, but the one area where Intel’s product really stands out is flexibility. The Roku has the most pre-built applications and “channels” for a streaming media box. The Chromecast is dirt cheap at just $30 or so. Even Amazon’s Fire TV Stick is clearly the best choice for streaming Amazon’s own multimedia services. But the Intel Compute Stick can do all of those things – in addition to operating as a standalone PC with Windows or Linux. Anything you can do I can do better…
But it’s not a product without a few flaws, most of which revolve around the status of the current operating system designs for TVs and larger displays. Performance obviously isn’t peeling the paint off any walls, as you would expect. But I still think at for $150 with a full copy of Windows 8.1 with Bing, the Intel Compute Stick is going to find more fans that you might have first expected.
Battle of the Sixes, they call it
GameBench is a low-level application released in 2014 that attempts to bring the technical analysis and benchmarking capability of the PC to the mobile device. You might remember that I showed you some early results and discussed our use of the GameBench testing capability in my Dell Venue 8 7000 review a few months back; my understanding and practice of using the software was just beginning at that time and continues to grow as I spend time with the software.
The idea is simple yet powerful: GameBench allows Android users, and soon iOS users, the ability to monitor frame rates of nearly any game or 3D application that you can run on your phone or tablet to accurately measure real-world performance. This is similar to what we have done for years on the PC with FRAPS and allows us to gather average frames per second data over time. This is something that was previously unavailable to consumers or press for that matter and could be a very powerful tool for device to device comparisons going forward. The ability to utilize actual games and applications and gather benchmark data that is accurate to consumer experiences, rather than simply synthetic graphics tests that we have been forced to use in the past, will fundamentally change how we test and compare mobile hardware.
Image source: GameBench.net
Today, GameBench itself released a small report meant to showcase some of the kinds of data the software can gather while also revealing early support for Apple’s iPhone and iPad devices. Primary competitors for the comparison include the Apple iPhone 6, the Samsung Galaxy S6, HTC One M9 and Motorola Nexus 6. I was able to get an early look at the report and offer some feedback, while sharing with our readers my views on the results.
GameBench tested those four devices in a total of 10 games:
- Asphalt 8: Airborne
- Real Racing 3
- Dead Trigger 2
- Kill Shot
- Modern Combat 5: Blackout
- Boom Beach
- XCOM: Enemy Unknown
- GTA: San Andreas
- Marvel: Contest of Champions
- Monument Valley
These games all vary in price and in play style, but they all are in the top 50 games lists for each platform and are known for their graphically intense settings and look.
Introduction and First Impressions
The ASUS X205 offers the full Windows 8.1 notebook experience for the cost of a Chromebook, and the design offers a surprising amount of polish for the price. Is this $199 Atom-powered notebook a viable solution as a daily driver? We're about to find out.
What do you use a laptop for? A thoughtful answer to this question can be the most important part of the process when selecting your next notebook PC, and if your needs are modest there are a growing number of very low-cost options on the market. For example, I personally do not play games on a laptop, typically alternating between web, email, and Microsoft Office. Thus for myself the most important aspects of a notebook PC become screen quality, keyboard, trackpad, and battery life. High performance is not of utmost importance, and I assure myself of at least speedy load times by always choosing (or installing) a solid-state hard drive. For those reasons when I first read the description and specifications of the ASUS X205 notebook, I took notice.
The X205 is a small notebook with an 11.6” display and 1366x768 resolution, essentially matching the form-factor of Apple's 11.6" MacBook Air. It is powered by a quad-core Intel Atom processor with 2GB of RAM, and onboard storage is solid-state - though limited to 32GB and of the slower eMMC variety (which is in keeping with many Chromebooks). There is adequate connectivity as well, with the expected wireless card and two USB 2.0 ports. One aspect of this design that intrigued me was the trackpad, which ASUS claims is using "smartphone technology", indicating a touchscreen digitizer implementation. Smoothness and accuracy are the biggest problems I find with most inexpensive notebook trackpads, and if this turns out to be a strong performer it would be a major boon to the X205's overall usability. I opted for the Microsoft Signature Edition of the X205TA, which carries the same $199 retail price but does not come preloaded with any trialware or other junk software.
At the outset this feels like a compelling product simply because it retails for the same price as an average Chromebook, but offers the flexibility of a full Windows 8.1 installation. Granted this is the “Windows 8.1 with Bing” version found on low-cost, low-power devices like this, but it offers the functionality of the standard version. While Chrome OS and Google's productivity apps are great for many people, the ability to install and run Windows applications made this highly preferable to a Chromebook for me. Of course beyond the operating system the overall experience of using the laptop will ultimately decide the viability of this inexpensive product, so without further preamble let's dive right into the X205TA notebook!
Motorola has released an updated version of their low-cost Moto E smartphone for 2015, adding faster hardware and LTE support to an unlocked device with an unsubsidized retail of just $149. In this review we'll examine this new phone to find out if there are any significant limitations given its bargain price.
There has been a trend toward affordability with smartphone pricing that accelerated in 2014 and has continued its pace to start this year. Of course expensive flagships still exist at their $500+ unsubsidized retail prices, but is the advantage of such a device worth the price premium? In most cases a customer in a retail space would be naturally drawn to the more expensive phones on display with their large, sharp screens and thin designs that just look better by comparison. To get the latest and greatest the longstanding $500 - $700 unsubsidized cost of popular smartphones have made 2-year contract pricing a part of life for many, with contract offers and programs allowing users to lease or finance phones positioned as attractive alternatives to the high initial price. And while these high-end options can certainly reward the additional cost, there are rapidly diminishing returns on investment once we venture past the $200 mark with a mobile device. So it’s this bottom $200 of the full-price phone market which is so interesting not just to myself, but to the future of smartphones as they become the commodity devices that the so-called “feature phones” once were.
One of the companies at the forefront of a lower-cost approach to smartphones is Motorola, now independent from Google after Motorola Mobility was sold to Lenovo in October of 2014. A year before the sale Motorola had released a low-cost smartphone called the Moto G, an interesting product which ran stock Android for a fraction of the cost of a Google Play edition or even Nexus device; though it was underpowered with decidedly low-end specs. After a redesign in 2014, however, the 2nd edition Moto G became a much more compelling option, offering a unique combination of low price, respectable hardware, a stock Android experience, and Motorola’s now trademark design language, to a market drowning in bloated MSRPs. There was just one problem: while the 2014 Moto G had solid performance and had (quite importantly) moved larger 5-inch screen with a higher 720x1280 resolution IPS panel, there was still no LTE support. Selling without a contract for just $179 unlocked made the lack of LTE at least understandable, but as carrier technology has matured the prevalence of LTE has made it an essential part of future devices - especially in 2015. Admittedly 3G data speeds are fast enough for many people, but the structure of the modern mobile data plan often leaves that extra speed on the table if one’s device doesn’t support LTE.

Samsung's new Galaxy S6 is unique in that it has metal sides and Gorilla Glass on both the back and front of the phone. The body is 143x71x6.8mm and it weighs a total of 138g, compared the the iPhone 6 at 138x67x6.9mm and 129g. The screen is 2560x1440, a density of 577PPI which compares favourably to the iPhone's 1334x750 at 326 PPI. The Inquirer was impressed by the quality of the screen as well as the colour calibration that they felt was significantly better than on the S5. As far as performance, the phone was tested by playing three hours of XCOM and it did so without stuttering or becoming uncomfortably warm. They tested the non-removable battery by looping a video, which the phone could manage for just over eight hours, slightly better than the competition though they lose the benefit of battery swapping thanks to the new design. Check out the images taken with the new camera and answers to other specific questions in their full review.
"Aware of customers' and reviewers' complaints, Samsung made a sweep of reforms in its smartphone division and "went back to the drawing board" with the 2015 Galaxy S6."

Way back in January of this year, while attending CES 2015 in Las Vegas, we wandered into the MSI suite without having any idea what we might see as new and exciting product. Besides the GT80 notebook with a mechanical keyboard on it, the MSI GS30 Shadow was easily the most interesting and exciting technology. Although MSI is not the first company to try this, the Shadow is the most recent attempt to combine the benefits of a thin and light notebook with a discrete, high performance GPU when the former is connected to the latter's docking station.
The idea has always been simple but the implementation has always been complex. Take a thin, light, moderately powered notebook that is usable and high quality in its own right and combine it with the ability to connect a discrete GPU while at home for gaming purposes. In theory, this is the best of both worlds: a notebook PC for mobile productivity and gaming capability courtesy of an external GPU. But as the years have gone on, more companies try and more companies fail; the integration process is just never as perfect a mix as we hope.
Today we see if MSI and the GS30 Shadow can fare any better. Does the combination of a very high performance thin and light notebook and the GamingDock truly create a mobile and gaming system that is worth your investment?

Find the LG G3 on Amazon!
- LG G3 32GB Unlocked US Version (T-Mobile) - $540
- LG G3 16GB Unlocked International Version - $380
- LG G3 32GB Unlocked International Version - $435
Last week I stopped by the T-Mobile store in the mall, handed over two old phones, and ported over two lines from Verizon. I walked out with a cheaper contract with unlimited data (versus 4GB on Verizon) and a shiny new (to me, it's been out for awhile) LG G3. Which brings me to this post.
First off, the LG G3 is huge. This is the
smallest tablet largest smartphone I have ever owned. Measuring 146.3 x 74.6 x 8.9 mm, the 149g smartphone is slightly smaller than the Apple iPhone 6 Plus and a bit chunkier at its thickest point. It is however easier to hold and operate (especially one handed) than the iDevice. The is dominated by a large 5.5-inch Quad HD IPS display (2560 x 1440 resolution) and features round edges and a curved back. I chose the white version, but it also comes in black, blue, gold, red, and purple (the international versions). Except for the top bezel that holds the webcam, light sensor, and speaker, and that bit of empty space below the display with the LG logo, the G3 has super thin bezels. In fact, the phone is not much larger than the display (certainly width wise).
The LG G3's display looks amazing with sharp text and extremely detailed videos (the included 4k content is great). It is highly reflective and I had to crank the brightness all the way up to be able to read it under direct sunlight (my S4 was similar in this respect). In other lighting situations, it worked really well.
An infrared transmitter, microphone, micro USB port, and 3.5mm audio jack are placed along the top and bottom edges of the phone. Like its predecessor (the G2), LG has placed the power and volume buttons on the back of the device rather than the sides (Update: I am generally liking this setup now). The recessed buttons sit beneath the camera lens and are easier to find and use than I expected them to be. Now that I am getting used to them, I think LG is onto something (good) with this button placement. There is also a 1-watt speaker in the lower left corner of the back cover for media playback and speakerphone calls. For a smartphone speaker it can get fairly loud and does what it is supposed to. It is not spectacular but it is also not bad. I mostly use headphones but it's nice to know that I have a decent speaker should I want to share my music.
The curved back cover makes it easy to hold in one hand (even if I can't hit all the on-screen buttons without a longer thumb heh) and I feel like it will be dropped less frequently than my previous phone (the Galaxy S4) as a result of the form factor. One big change with the G3, for me, is the lack of buttons below the display (capacitive or physical), but I am slowly getting used to the on-screen navigation on Android (especially once I figured out I could long press the recent apps button to regain the menu button I miss from my S4).
Aside from the display, the G3 features a 2.1MP front facing camera and a 13MP rear camera. The rear camera is where things get interesting because it is paired with a dual LED flash, laser focus, and optical image stabilization (OIS) technology. Outdoor shots were excellent and indoor shots with enough lighting were great. In low light situations, the camera left something to be desired, and I was kind of disappointed. Using the flash does help and it is quite bright. However, I tend to not like using the flash unless I have to as photos always look less natural. For as small as the camera is though (the lens and sensor are tiny), it does pretty well. In good lighting conditions it is trounces my S4 but the (upgrade) is much less noticeable with less light (the G3 does have a much brighter flash).
The laser focus is a really cool feature that works as advertised. The camera focuses extremely quickly (even in low light) allowing me a much better chance to capture the moment. It also refocuses (tap to focus) quickly.
The camera software is not as full featured as other smartphones I have used, however. I was put off by this at first as someone that likes to tinker with these things but at the end of the day it does what it is supposed to and it does it well (which is to take photos). You can swipe to switch between the front and back cameras, choose from a couple preset modes, and adjust basic settings like resolution, voice controls, HDR, and shutter timer. For "selfie" fans, LG has a feature where you can make a fist in the air and it will start a countdown timer. While I have not tried the voice commands, I did try the gesture and it does work well.
Anyways, before this turns into a full review (heh), it might help to know what's under the hood as well. The G3 is powered by a Qualcomm Snapdragon 801 SoC which pairs four Krait 400 CPU cores clocked at 2.5 GHz with an Adreno 330 GPU. The phone comes with either 16GB internal storage and 2GB of RAM or 32GB internal storage and 3GB RAM. I chose the higher end model to get the extra RAM just in case as I plan to have this phone for a long time. It supports 4G LTE, 802.11ac Wi-Fi, Bluetooth 4.0, GPS, and NFC (Near Field Communication). You can also use it with Qi-enabled wireless chargers if you purchase a supporting back cover. The G3 is running Android 4.4.2 on T-Mobile but it does support Android 5.0 and some carriers have already pushed out updates.
The G3 comes with a 3,000 mAh battery and a 1.8 amp USB charger. It does take awhile to charge this thing (my 2.1 amp Samsung charger is a bit faster), but once it is fully charged it will easily last all day including listening to streaming music and audiobooks, text messaging, and web browsing. (Update: I don't have specific battery life numbers yet, but I generally only need to charge it once a day so long as I keep the display brightness around half. If I crank the brightness all the way up I can almost feel the battery draining by the second heh.)
Like Samsung, LG has a battery saving feature that will kick in at 30% to conserve battery but turning down the screen brightness, turning off radios that are not active, and a few other configurable battery drainers (haptic feedback, notification lights, and account syncing). I do like their battery settings page as it will estimate the time needed to charge and the time remaining as it discharges along with a nice graph of battery percentages over time. Other Android phones have something similar but LG has fleshed it out a bit more.
Just for fun, I installed 3DMark and ran the Ice Storm benchmark. The LG G3 maxed out the Ice Storm test and scored 10,033 points in Ice Storm Extreme. Further, it scored 16,151 in Ice Storm Unlimited. In comparison, the (apparently extremely popular judging by the feedback) Samsung Galaxy Centura scored 536 in Ice Storm and 281 in Ice Storm Extreme respectively (hehe). My Galaxy S4 is no longer available for me to test, but TweakTown was able to get 6,723 in the Ice Storm Extreme test.
LG packs light with only the smartphone, USB cable, USB charger, and a quck start guide included in the box. No headphones or extra accessories here.
In all, so far so good with the LG G3. I am very happy with my purchase and would recommend checking it out if you are in the market for a large display-packing smartphone that's not an iPhone 6 Plus or Galaxy Note 4 (which Ryan recently reviewed). If you want the latest and greatest Android phone and can afford the premium (about $300 more in my case when I compared them), grab the Note 4. On the other hand, if you are looking for a Android smartphone with a large display, good battery life, and decent hardware specifications, the LG G3 is a respectible choice that delivers and doesn't break the bank.
Have you tried out the G3? What do you think about the trend for larger and thinner smartphones? This is hardly an exhaustive review and there are things I didn't get into here. After all, I'm still checking out my G3. With that said, from first impressions and about a week of usage it seems like a really solid device. I've since fitted it with a screen protector and a case so as to not break it – especially that hi-res display!
