NVIDIAs Shield gaming handheld was a peculiar, singular device: an expensive Android portable aimed squarely at consumers that had already purchased high-end desktop GPUs. It was novel and fun, but it wasnt for everybody: If you werent a gamer, there wasnt much point to owning a Shield. Now, thats changing: NVIDIAs second-generation gaming device isnt a quirky handheld; its a tablet. Specifically, the Shield tablet is a $299 8-inch gaming slate powered by NVIDIAs new Tegra K1 processor. It wants to be everything to everyone: a high-end gaming device, a superb media tablet and a performance benchmark that will drive the mobile industry forward. Most of all, it wants to appeal to more than just the hardcore gamer. Does it? Lets find out. Hardware Black, green and silver were the colors that defined the original Shield, but this years model is decidedly more monochrome: The slate is draped in a mix of glossy and reflective blacks. Its a clean, if less distinctive, look, but the absence of color doesnt mean the Shield is just another cookie-cutter tablet. If anything, it looks more like an HTC One than a Nexus 7, sporting long, matte black speakers on the devices top and bottom edges. The top speaker bar is split in half by a 5-megapixel front-facing camera with an same shooter (sans autofocus) on the rear of the device. Lets not flip the tablet over just yet, though -- a handful of ports, holes and buttons run around the edges. Most of the action is on the right: a power button, volume toggles, a microSD slot and an embedded, passive stylus for pen input. The WiFi model also features a walled-in cutout for a micro-SIM card slot -- an ever-present reminder that you could have waited for the upcoming LTE model. The bottom edge is host to a simple bass speaker vent, while the left side is marked only by the magnetic connectors that latch onto an optional screen cover. The top has a little more going on: another bass vent, a headphone jack, micro-HDMI connectivity and the all-important power/micro-USB port. Oh, and that backside? Just a smooth, matte surface accented only by the word Shield, etched in glossy black lettering. Classy. Although the tablet feels sturdy and well-built, it isnt perfect. Putting all of the Shields ports on one half of the top edge leaves it feeling a little crowded, and thumbing its physical toggles gave me second thoughts about its build quality. Its not that it feels cheap or painful to hold (a tiny, chamfered edge between the screen and tablet sides ensures a comfortable grip), but the buttons tactile response is a little mushy. The soft depressions are okay for tweaking volume, but I was never sure if I was using the power button correctly. Did it go down all the way? Did I miss it? Until the screen reacted, I just couldnt tell. The tablets folding, magnetic cover (sold separately) soon became my favorite way of waking the device: just flip it open, and the screen is on. Looking for precise specs? Okay, weve got those, too: The Shield tablet measures 8.8 inches (221mm) long, five inches (126mm) wide and 0.35 inch (9.2mm) thick. For comparisons sake, that makes it taller, wider and thicker than the Nexus 7 -- though it does sport a larger 8-inch, 1,920 x 1,200 display. Weighing in at 390g (13.7 ounces) its a bit heavier, too, though its still lighter than both versions of the Kindle Fire HD. If you were to crack the Shield open (please dont), youd find NVIDIAs latest mobile chip: a 192-core Kepler GPU paired with a 2.2GHz quad-core Cortex-A15 processor. The Tegra K1 is the companys pride and joy (at least for now; a 64-bit variant is currently in development). It features a mobile GPU designed specifically to push the limits of Android and offer PC class and modern console class graphics on a small screen (more on that later). The tablet also packs 2GB of RAM, 802.11a/b/g/n WiFi with 2.4GHz and 5GHz support, Bluetooth 4.0 LE and a GPS radio. Right now, the Shield can be had only as a WiFi tablet with 16GB of storage, but NVIDIA plans to offer an LTE version later this year, which will come with twice the storage space and access to five LTE bands (2/4/5/7/17) and four HSPA+ bands (1/2/4/5). Itll be unlocked, too, but heavy users may be tempted to wait just for the extra storage. Because really, it doesnt take long to fill up 16GB -- especially on a device geared toward gaming. Display and sound The Shield tablets 8-inch, 283-ppi, 1,920 x 1,200 IPS screen may not be the brightest or sharpest tablet display, but I was hard-pressed to find a legitimate complaint. Contrast, color quality and a 380-nit brightness were all more than enough for indoor use, though like most glossy displays, it can be difficult to read in direct sunlight. Still, it has clear, balanced colors, great contrast and wide viewing angles. I read a half-dozen comics, watched a movie and played hours of games without thinking twice about the display quality. Earlier, I made a point of calling out the Shields speakers. They were the first thing I noticed about the tablet, and with good reason: Their design enables a true hand-held stereo experience. Its an exception to an irksome standard; many tablets and smartphones cripple themselves by banishing their speakers to one end of the device, making stereo sound separation impossible. Considering how much media we consume on these devices, thats just unacceptable. Thankfully, NVIDIA got it right, placing a speaker on each end of the tablet. So, how does it sound? Just okay. The Shields speakers dont crackle or distort, but they arent incredibly loud either. The sound is balanced, and good overall, but it wont fill a room and it definitely cant replace a good set of headphones. This makes the Shield tablets audio experience a little mixed: Its not as loud as its predecessor, but its speakers arent as tinny either. At the end of the day, however, the tablets design makes it impossible to accidentally block the speakers by holding the device incorrectly, and thats worth at least some credit. Direct Stylus 2.0 One of the best ways to add value to a tablet is to bake in stylus support. The problem is, active, pressure-sensitive pens (e.g., the Wacom tech used in the Samsung Galaxy Note) are expensive. Passive stylus technology is cheap, but offers an inferior pen experience. NVIDIAs solution was to create Direct Stylus: a carefully designed passive pen that mimics an active stylus via clever software tricks and a little GPU wizardry. This not-so-active stylus first showed up in the Tegra Note 7, but NVIDIA gave it an upgrade on the Shield, renaming it Direct Stylus 2.0. That numerical identifier mostly adds up to a redesigned pen, starting with a longer, narrower tip that curves slightly. Thats important because whereas most styli imprint a dot-like shape on the surface of the tablets screen, this pen leaves more of an apostrophe. The added surface area might make the pen more accurate, but most of the pens performance improvements can be chalked up to better software. The Shields best showcase of this is Dabbler, a painting app that leverages the tablets GPU to simulate the effect of paint on real materials. I am not an artist. Dabbler is actually quite impressive -- it takes the type of paint, material, lighting and even the tablets position into account. A line drawn in the apps watercolor mode, for instance, will slowly soak into the surface of the simulated paper, and will even bleed down into other sections of the material if the apps gravity mode is turned on. Similarly, oil paints can glob and cake up on the surface of a canvas, and the artist can change the direction of the light source to affect how the final painting looks. Its a neat concept, but its short on features: There arent many tool or paint styles to choose from, and it lacks the simulated pressure sensitivity that the technology is capable of. While Im not much of a fine artist myself, I did find writing with the stylus to be a pleasure. The passive pen worked well enough in notebook apps like Evernote and JusWrite, but I was most impressed by its handwriting recognition. My childish penmanship -- said to be unreadable by my K-12 teachers, college professors and employers -- was consistently recognized by the Shields software. This feature can be used in any app that accepts text input, too: All you have to do is hold down the spacebar for a second and switch to the handwriting keyboard. Pretty smooth. Shield Wireless Controller The Shield makes a nice standalone tablet, but lets not kid ourselves: If you want to get any serious gaming done on this device, youre going to need a controller. Dont worry, NVIDIA has you covered. Introducing the Shield Wireless Controller, a $60 WiFi gamepad that promises lower latency than your average Android controller. It isnt the only option Shield buyers have (the tablet also connects to any Bluetooth gamepad), but it has the advantage of being designed specifically for Shield devices. This means it has a few extra features -- namely, a clickable mousepad and a dedicated NVIDIA button (for launching the NVIDIA hub). That first feature may seem like an odd thing to tack onto a gaming controller, but for the Shield, it makes a lot of sense. One of the devices flagship features is NVIDIA GameStream, its ability to wirelessly stream high-end PC games directly from a GeForce GTX-powered Windows machine -- but desktop games dont always play nicely with the streaming setup. Some have mouse-operated launcher menus, or refuse to recognize the gamepad until the user activates a specific setting. The official gamepads mousing surface makes it easy to navigate these menus without fiddling with the tablets touchscreen or the host computer itself. Its a little under-sensitive (NVIDIA says its working on this), but still convenient. Its compatible with the original Shield too. All told, its the perfect companion for either device when connected to a TV in console mode. The rest of the gamepad looks pretty standard: two analog thumbsticks, a directional pad, four face buttons, two bumpers and a pair of triggers. Its a good-feeling controller -- like an oversized Xbox 360 pad with the PlayStation thumbstick layout -- but its hardly a revolution in gamepad design. The only standard its missing is force feedback vibration, though it does have a few other bells and whistles: volume controls, a built-in mic and a headset jack that pipes in all audio from the tablet. Unfortunately, the microphone only works in Android: Games streamed from the PC simply wont recognize it. While its handy to have an internal microphone for Twitch streaming, I found that it had an annoying tendency to pick up button presses and other controller noises. If youre planning to stream your gameplay, use a headset. Finally, the controller has one more quirk: capacitive start, back and Android home buttons. These touch-sensitive toggles are a little odd at first, but considering theyre designed for an Android tablet, they feel fine. They also pull double-duty: Long-pressing the back or start buttons often brings up context-sensitive menus, and it doesnt take long to get used to them. My only disappointment with Shields wireless controller is how single-minded it is -- it works like a dream with NVIDIAs own hardware, but wiring it up to your computer to use as a standard gamepad produces null results. I expected this, sure, but having an extra PC controller would have been a nice perk. Software The Shield runs a version of Android 4.4.2 thats pretty close to stock, although NVIDIA did manage to weave in a few extra features. The best of these, without a doubt, is the tablets integrated Twitch support: Pull down the notification menu at any time, in any app, and you can immediately stream your tablets screen, microphone and front-facing camera to Twitch. Technically, this is the tablets share menu, and its the mobile equivalent of NVIDIAs GeForce Experience ShadowPlay feature. The pop-up menu can stream to Twitch, capture the last five minutes of screen time, manually record the screen and save it to memory or simply take a screenshot. The menu can also be called up with a long-press on the gamepads back button too, making it easy to access in any situation. The whole thing is robust, beautiful and seamlessly integrated into the OS. Most of the OS other tweaks are carryovers from previous products. Holding the gamepads start button will bring up NVIDIAs gamepad mapper, for instance. This overlay allows you to create virtual touch spaces that you can manipulate with the gamepad, making it possible for any game with touch controls to be played with the controller. Making profiles can be a little tedious, but almost every game already has a mapping sourced from the community, which can be downloaded with the touch of a button. The DirectStylus features found in the Tegra Note slate are here too -- pulling out the pen brings up a menu of compatible apps, and additional buttons can be added to the navigation bar for quick access to stylus-exclusive controls. These are all nice tweaks to the OS, but the true Shield experience hinges on launching the Shield Hub app, formerly known as TegraZone. Despite the rebranding, the Shield Hub is largely the same experience NVIDIA baked into (and repeatedly updated for) its last portable gaming device. Its basically the devices console interface, a launcher for all of the Shields gaming functions. Theres a store section that redirects to the Google Play page for featured and optimized games, a news feed for NVIDIA announcements and disparate app drawers for Android games, media apps and PC games. There are search and settings options in NVIDIAs menu, too, but these just kick the user back to the standard Android interface. While the NVIDIA hub isnt technically new, its gone through several major overhauls since its introduction on the original Shield. Its better designed, easier to navigate with a controller and generally more pleasing to the eye. In fact, when the tablet is connected to a television, it almost feels like a proper console OS -- although the controller has a mouse emulator for a reason. It still isnt perfect, but its come a long way. Camera In general, tablets shouldnt be used as your primary camera for capturing lifes precious moments: Theyre big, awkward and shooting pictures with them makes you look silly. You shouldnt do it, ever -- and you definitely shouldnt do it with NVIDIAs Shield tablet. Not only will you look ridiculous, but also your pictures will turn out lousy. The Shields rear-facing 5-megapixel shooter is mediocre at best. The Shield can produce clear, if muted images in a well-lit interior space, but it stumbles in darker rooms and the great outdoors. The camera simply cant compromise between shadows and highlights, and blows out images in the presence of any bright surface. My test shots are full of over-brightened flowers that bleed together and soft images lacking texture depth. The Shields rear-facing camera will probably do in a pinch, but chances are its outclassed by your smartphone. Most tablets skimp on the front-facing camera, opting for a lower-resolution sensor. Not the Shield, though. The tablets front camera is the very same as the rear one. It still wont land you any award-winning shots, but I can appreciate the higher-resolution selfie cam for the sake of the devices Twitch integration: If youre going to stream your face to the internet, it may as well be shot with the best camera available. Performance and battery life Ask NVIDIA about its new Tegra K1 mobile processor and itll beam at you like a proud parent. This is a mobile GPU boasting 192 Kepler cores and the wherewithal to keep up with PC gaming standards: Open GL, DirectX 12 and even support for Unreal Engine 4. Kepler is the key buzzword here: Tegra K1 is built on the same architecture that powers NVIDIAs desktop-class GPUs. Combined with a 2.2GHz quad-core Cortex-A15 processor (with an extra +1 core to handle menial, low-power tasks), the Shield runs on what NVIDIA is claiming to be the worlds fastest mobile processor. NVIDIA Shield Tablet Tegra Note 7 Nexus 7 Samsung Galaxy Tab S Quadrant 2.0 20,556 16,066 6,133 18,597 Vellamo 3,055 3,314 1,597 1,672 3DMark IS Unlimited 30,970 16,473 10,271 12,431 SunSpider 1.0 (ms) 463 586 602 1,109 GFXBench 3.0 Manhattan Offscreen (fps) 31 N/A 5 5.5 CF-Bench 43,033 34,386 15,366 31,695 SunSpider: Lower scores are better. All told, the NVIDIA Shield tablet is delightfully fast, offering one of the smoothest, most stutter-free experiences Ive ever had with an Android tablet. Switching between apps and menus feels fluid, and even processor-heavy applications load in mere seconds (not including extra loading time for high-end games, of course). More often than not, I found myself waiting on my network connection to catch up to the device -- slowly watching a status bar as it downloaded the next issue of the comic I was reading or waiting for a server to deliver my web page. If youre hooked on numbers, take a look at the table above: The Shield made notched marks in every single benchmark. The Shield kept pace with average battery life expectancies, too: It lasted for nine hours of near-constant use, including a good deal of comics reading and Netflix streaming. Engadgets battery rundown test (video looping at a fixed brightness) matched my lazy-Sunday test pretty closely; the 5,300mAh battery gave out after almost eight and a half hours. With lighter usage, the Shield can also last for a day and a half or more without needing a recharge. Thats about an hour more than last years Nexus tablet, but its hardly best in class -- the Shield still falls four hours short of Samsungs 8-inch Galaxy Tab S. Tablet Battery Life NVIDIA Shield Tablet 8:23 Microsoft Surface 2 14:22 (LTE) Apple iPad Air 13:45 (LTE) Samsung Galaxy Tab S (10-inch) 12:30 Samsung Galaxy Tab S (8-inch) 12:22 Apple iPad mini with Retina display 11:55 (LTE) Amazon Kindle Fire HDX (7-inch) 10:41 (WiFi) Nexus 7 (2012) 9:49 Kindle Fire HD (8.9-inch) 9:01 Sony Xperia Z2 Tablet (2012) 7:57 Nexus 7 (2013) 7:15 Gaming This is why youre really here, right? Yes, the Shield makes an admirable media tablet, but thats not why NVIDIA built it. This is a device billed as the ultimate gaming tablet, a slate to take mobile gaming to a new level. Thats pretty much the same promise NVIDIA gave us with the original Shield. Does the tablet form factor and the companys new Tegra K1 processor make that much of a difference? Yes, and no -- it kind of depends on what your goal is. While its true the tablets Tegra K1 outclasses the Tegra 4 chip found in the hand-held Shield, its hard to tell in most games. With the exception of a few NVIDIA-optimized titles, most Android games simply arent designed with high-performance graphics chips in mind. Titles like Sonic The Hedgehog 4: Episode II, Grand Theft Auto III or Jet Set Radio arent going to look appreciably different on either device -- though all of them run great. In fact, the only titles where we could see any notable difference were ones designed specifically for NVIDIA Shield devices -- namely, Valves Android ports of Portal and Half-Life 2. Valves classic shooter and Stockholm Syndrome puzzler made their way to the NVIDIA Shield handheld back in May, but they were slightly downgraded ports. Both games suffered occasional lag in tense moments and lacked more robust lighting effects. Theyre still playable on NVIDIAs original Shield, but on the tablet, theyre a bit better. Textures seem to be a bit more crisp and dynamic lighting now reflects off of in-game surfaces. Most importantly, the games run more smoothly and stutter less often. While these games do look better on the Shield tablet, theyre available on the older device as well. That said, tablet-exclusive games are coming. Trine 2, for instance, ships with every Shield tablet and requires a Tegra K1 processor to run. It looks pretty fantastic too, and features textures and lighting on par with the games console and PC ports. Sadly, its only a hint of the power the K1 has to offer. NVIDIA has shown impressive demos of the processor (and indeed, the Shield tablet itself) featuring stunning graphics powered by Unreal Engine 4, but no top-tier games take advantage of this power. In fact, the only UE4 game currently available for the device is Tappy Chicken, a simple clone game created as an example of a scripting system. Is the NVIDIA Shield tablet the most powerful Android gaming device available? Probably, but right now that power is underutilized. Its a problem the original Shield device faced too -- a bizarre, but tantalizingly capable product with precious few apps that could leverage its power. While its true that NVIDIA is continually pushing to get more Tegra-optimized games on the market, the fact of the matter is that these titles trickle out at an inconsistent pace. Fortunately, Shield owners arent shackled by the limits of the Android marketplace. GameStream and Console Mode Both the NVIDIA Shield tablet and hand-held Shield are powerful, well-made Android devices, but lets be frank: The aforementioned GameStream technology is easily half the reason gamers are buying these products. We covered the feature in our original Shield review, but its worth revisiting -- its the devices killer app, and its better than ever. Over the past year, NVIDIA has slowly been pushing updates to its existing Shield handheld, improving its PC-streaming features and building a smoother experience. Naturally, these updates have found their way to the tablet, and it shows: GameStream is noticeably more reliable than it was a year ago. It has lower latency and crashes less often (hardly at all, in fact). Its not perfect, but most of the time input lag was low enough that I dont notice it. On my home network, the experience was good enough that I could almost hold my own in Titanfall over GameStream. Thats a huge improvement. Streaming PC games to a tablet is OK, but I found the experience to be more enjoyable on a big screen. Plugging a micro-HDMI cable into the Shield prompts it to reboot into console mode, disabling the tablet screen and optimizing video output for your television (theres also a mirror mode, but this leaves Androids navigation buttons on your TV screen). With NVIDIAs updated Tegra Hub and the official Shield gamepad, this setup works like a dream. The Tegra Hub serves as an easy-to-navigate, well-thought-out console interface, and the controllers aforementioned touchpad makes it easy to sort out PC-streaming problems (unexpected pop-up windows and the like) from the couch. Technically, this experience was, and still is, possible with the original Shield, but its worth noting that a year of updates have significantly improved the experience. The only drawback to console mode? You cant wake it from sleep using the controller. The only option is to fiddle with that mushy power button. Blergh. The competition If youre looking at the Shield tablet for high-end Android gaming and PC streaming, you really only have one other option: the Shield portable. NVIDIAs GameStream technology is proprietary -- and although some enterprising folks in the Android community have reverse-engineered it, no other Android product on the market offers a comparable feature. It isnt a tablet, and isnt quite as powerful, but NVIDIAs original Shield can be had for $100 less than our $299 Shield tablet review unit (and you wont have to shell out an additional $60 for the Shield controller, either). If youre just looking for a solid tablet, on the other hand, then youve got choices. If the Shields 1,920 x 1,200 IPS screen isnt good enough for you, take a look at the $400 Samsung Galaxy Tab S 8.4 -- it has a bright 2,560 x 1,600 display and a big enough battery to keep it running for over 12 hours. Prefer iOS? Apples iPad mini with Retina display offers a similar runtime and resolution for the same price. Google hasnt unveiled its latest Nexus tablet yet, but last years model is a contender on its own: At $230, it offers all of the non-gaming features a potential Shield buyer could want at a significantly reduced price. If youre looking for more battery life, however, take a look at Amazons 7-inch Kindle Fire HDX: it wont cost a dime more than the Nexus 7, but itll last longer. Wrap-up When Engadget reviewed NVIDIAs original Shield handheld, we called it a truly strange device, albeit a fun, powerful and completely worthwhile one. The Shield tablet is everything that device was, but less odd. As a tablet, its far more versatile than the handheld was, making its lack of Tegra-optimized (and exclusive) games easier to forgive. Its still a powerful gaming device, but its no longer an outlier. At the end of the day, the NVIDIA Shield is a solid, worthwhile 8-inch Android tablet in its own right, and it just happens to have a host of novel features, to boot. Sadly, making the most of the device requires an extra $60 controller and an NVIDIA GTX GPU -- making the full Shield experience an expensive proposition.
