NVIDIA is doing something different with Tegra 4, very different. To bring up its silicon, each vendor usually makes a reference design phone and tablet with a selection of approved components, packages a BSP (Board Support Package), and ships that and some engineers to customers. Rather than never letting the reference design see the light of day, this time NVIDIA also made it into something they can sell directly, a portable gaming device called Shield.

It’s no secret that Tegra 4 isn’t exactly the success that NVIDIA probably hoped it would be. While the initial word was that Tegra 4 had an obvious set of design wins following momentum from products which shipped in 2012 through 2013 with Tegra 3, but it’s obvious that Shield will now effectively serve as NVIDIA’s launch vehicle for Tegra 4.

Shield is an aspirational product and not an easy one to nail down – enthusiasts are picky about controllers, Android gaming is still largely an unknown, and the question remains what presence handheld gaming consoles will have in the future. To answer all those questions NVIDIA sent over Shield, a Falcon Northwest Tiki with GTX 760 inside, and Parrot AR Drone 2.0 for us to review. Read on for the full story.

Introduction and Hardware

With Shield, NVIDIA gave us a rare glimpse into some of the stages of design. When Anand and I saw Shield at CES, it was more of a prototype than real, reviewable sample of the portable gaming device. The analog sticks weren’t weighted right, the plastic felt somewhat creaky, the triggers and bumpers felt hollow and strange, and the D-Pad worked, but not amazingly so. It was exactly what you’d expect from a prototype, and as Shield inched closer to final release the hardware got successively better and better, until the final unit dropped on our doorstep.

The hardware that is the shipping Shield today is a world better, it’s everything I was hoping Shield would end up being in terms of a controller, with the right balance and in-hand feel.

There’s so much scrutiny on the fit and finish of mobile devices these days, for NVIDIA to build a mobile device and gaming controller at the same time invites a whole new level of scrutiny, potential issues, and things to get tuned just right. I’ve purchased a few high end gaming controllers in my day (like a kitted out $125 Scuf FPS Competition Xbox 360 controller that I love), but hesitate to review them because of just how much there is to talk about, and how much of it comes down ultimately to taste.

Anand and I gave feedback to NVIDIA early on that they should arguably use the Xbox 360 controller as something of a baseline for tuning their controller components. With the Shield what we get is nearly exactly that. The analog trigger resistance, bumper clickiness, and analog stick friction feel remarkably like the 360, perhaps just a tad less. I consider the 360 controller out of the box nearly perfect, but some of that is adaption and familiarity versus being some global maxima for perfection. At the same time, if the PS3 controller is your bar, you’re probably going to have a bad time initially with Shield until you’ve adapted. Where Shield does borrow somewhat from the PS3 controller is the analog stick positioning, which is bottom center, instead of opposed top left and bottom right. One of my initial complaints was that my thumbs can collide with each other when left stick is at limits to the right, and right stick is at limits to the left (a complaint about the PS3 I have as well). NVIDIA seems to have spaced these a bit more and my thumbs aren’t quite hitting as much as they were previously.

Since the display has to close flat on the control surface, some of the shape is gated by the limitation that you can’t have the analog sticks or buttons ramming through the display, so they’re sunken down a bit. The rest of the interface (A/B/X/Y, NVIDIA, Back, Home, Start, Volume and D-Pad) rest roughly in the same plane. The spring preload on the buttons is great, though I wish they were maybe a touch less mushy for A/B/X/Y, and although I’m not much of a platform gamer, the D-Pad feels so much better now than it did before.

The shape of Shield fits in my hands really, really well. The bottom is a grippy, rubberized material that grabs the hands well and plants the Shield solidly on any surface you put it down on. The interesting shape on the back side, means I can rest my middle finger in a sort of folded position along the inside (something you can’t do with most wireless controllers) and it feels great. I have no issues with the mass of Shield fatiguing my hands or feeling awkward since it’s so well balanced and ergonomically shaped down there.

On the front of Shield is a green-tinted intake and grille for the device’s active cooling. When I first heard that Shield had active cooling I was a bit shocked, but it turns out to be completely unobtrusive in actual use.

With Shield open you can see the 5-inch 720p display surrounded by a somewhat large bezel. This remains my only complaint about Shield – I wish it had a slightly larger display that took up more of the fold-out area. Below that are stereo speakers that go loud (I love that stereo is now a feature showing up in more devices) and in the very middle is a microphone.

On the back of Shield are its I/O ports, which are microUSB 2.0, mini-HDMI, headphone jack, and microSDXC. There’s also the exhaust grille for Shield’s active cooler back here. Above the microUSB 2.0 port is a small charge status LED which is amber while plugged in and charging, and green when fully charged. I remain confused by the choice of mini-HDMI, when smartphones and tablets have universally adopted the microHDMI format plug, and I’m buried in those cables compared to a relative scarcity of mini-HDMI ones, though NVIDIA has shipped mini-HDMI GPUs before.

On the top of Shield is, well, a small shield, which NVIDIA calls a tag. This snaps onto the top and adds a bit of a customization option, it’s held in place with magnets. Out of the box the tag is a metallic silver material. It looks great but I’ve already managed to put a few hairline scratches into it, which leads me to my next point.

NVIDIA has a carrying case option available, but it really needs to give some kind of carrying case away with Shield. Although Shield feels really well constructed, right down to even the hinge mechanism, I’d like a better way to protect it, especially while traveling. I know I’m going to put more scratches into the silver tag while traveling with Shield in my bag, for example.

Shield’s in-hand feel is really, really good. NVIDIA seems to have nailed the device on the controller side, which is no small task considering this is their first attempt. As a handheld mobile device, it’s definitely on the large side, but it’s hard to really say anything negative about it since this is an entirely new form factor. Other smartphone solutions with a foldable control scheme on the phone are similarly bulky, the upside is with Shield it’s all packaged better. Again my only wishes from a purely hardware perspective would be an in-box case, bigger display, and inclusion of a front facing and rear facing camera of some kind – if nothing else for video chat and taking photos when you’ve got the Shield already in your hand.

    My tablet is 1.3 kg and I have no problem using it like a book. At first I lent it against my leg, desk and bed until I got used to the weight. If 500 grams is to heavy for you try resting your elbows on an arm rest while your playing.

    The device is very elegant. Nvidia is providing gaming with VNC. Try using an openGL game on a wired network with RDC. It sucks and it uses PC hardware. This is an 500 gram handheld android device that lasts for 10 hours.

    Please don't be "That Guy." There are links to Dailytech in the side bar if you must use that tone.

    Ergonomics play a big part is determining if an item can be held for a long time. It is about the weight distributions. E.g. holding a stick of 0.5KG as compared to holding a spherical item of 0.5KG give totally different feeling.

    Your irresponsible choice of words like "junk", "bias", "ugly" simply shows your prejudice.

    You clearly don't handle objects of differing weights, sizes and shapes very often.
    A 30Kg object can feel lighter than a 15Kg object if it's easy to hold, well balanced and controllable shape if the 15Kg one is awkward.

    I remember when Anandtech had almost exclusively readers with an IQ >90.

    Haters gonna hate. Never heard of weight distribution? Reply

    I don't see how that could have been considered a rant.

    Troll perhaps?

    Maybe you should put down the Xbox controller and pickup a dumbell or barbell once in a while.
    Or would that hurt you quest to become the ultimate dungeon master?

    What is unbelievable is how clueless and stupid some people can be. You have no idea what Brian and Anandtech are about, you are blatantly rude, and are so ignorant about weight and balance I'm surprised you can actually type. And if Anandtech feels that this response to your post goes overboard I'm sorry, but it is no more offensive than someone calling Brian dishonest in any way, and I don't believe in letting bad behavior go unchecked.

    I used to swing a 1-lb hammer all day long, and there are hundreds of thousands, if not millions over the years, of construction workers who did the same. That's one pound at the end of a stick, swinging it with one hand, not holding it in 2 hands relatively close to your body. Since you are so ignorant let me point out that 1 lb is 454 grams, and that measurement is for the head of the hammer, not the whole hammer. There ar many workers in many fields who deal with a lor more weight than that, 8 or more hours a day, 5 or more days a week.

    Oh, and by the way, a regular wireless Xbox 360 controller weighs 265 grams. So, what you are talking abut here is a little over 1/5 a kilo more weight.

    I'm sorry that the heaviest thing you lift in your life is a Big Mac and you have no muscle tone. I'm sorry that your Mommy was mean to you all your life and so now you have a bad attitude about everything. Here's a clue though - regardless, you are responsible for your behavior in public, responsible for your physical condition, and responsible for your beliefs. Consider this a wake-up call. Get a clue before you post next time.

    Seriously, a good counselor can help a lot, I highly suggest you find one ASAP.

    People hold 7-inch tabs that are 400-500g with one hand and a funny grip. So a little over a half-kilo with two hands and real grips seems doable. Reply
