As I discussed in our launch article last week, the Shield tablet is very much the culmination of lessons learned from 2013. While the Tegra Note 7 was a decent tablet, it had to eke out a profit through hardware sales against competition that was willing to sell their tablets with no profit on hardware. Meanwhile the Shield portable was a good portable gaming device, but it was far too specialized to be anything but a gaming device. Without an established gaming ecosystem, NVIDIA struggled against established competitors.

As a result of these influences, today NVIDIA is becoming the first OEM to launch a serious gaming tablet running Android. While gaming tablets have been done before, they’ve been few and far between. Now it has always been technically possible to take a high end tablet and make it usable for gaming, but for the most part these attempts are marred by either the need for root or an application that requires extensive work on the part of the user to create proper control profiles for each game. In addition, the SoC in the tablet is often underequipped for intensive 3D gaming.

That’s where the Shield tablet comes in. With Tegra K1, a dedicated controller, 2x2 WiFi, and a huge amount of custom software, there’s definitely a lot of ground to cover. Once again, while the Shield tablet is a gaming device, it must also be a good tablet. To that end, NVIDIA has tried to differentiate this tablet with DirectStylus 2 and dual front facing speakers/bass reflex ports. I’ve included a table of specifications below to give a general idea of what the tablet is like.

Hardware

Outside of the basic specs, the tablet itself has a much more subtle industrial and material design. While the large speaker grilles are maintained from the Tegra Note 7, the dimpled look and feel is gone. Instead, the finish is very much reminiscent of the Nexus 5. The feel isn’t quite rubbery the way soft touch finishes tend to be. Instead, it feels more like a high grain matte polycarbonate. Along the sides, there’s a noticeable chamfered edge where the back cover meets the display, although in practice this mostly affects aesthetics rather than in hand feel. The flip cover that is designed for the device is almost identical to the one in the Tegra Note 7, and folds up similarly. As with the Tegra Note 7, there are two angles that the flip cover can take. Overall, the aesthetic is much more subtle than the Tegra Note 7, and looks quite similar to the Nexus 7 (2013).

While it’s important for the tablet portion of the device to have decent material and industrial design, ergonomics and material design are critical for the controller. While the Shield portable had great ergonomics, it was heavy because the entire device had to fit in the controller. With Shield Tablet, that’s no longer the case. The result is that the controller is significantly lighter. While it still has some heft to it, I no longer feel the need to rest my hands against a table after significant playtime.

The controller itself is just as good as the one on the Shield Portable. The buttons, triggers, bumpers, and joysticks are all very close in feel. The one big difference are the tablet/Android controls. Instead of physical buttons, they’ve replaced the physical buttons with capacitive ones. The volume controls have also been moved down to the bottom of the controller and changed from a single button that triggers on-display volume controls to a rocker that allows direct manipulation of volume. Just above the volume rocker is a clickpad, which can be used to move a cursor through the UI. While this option exists, it’s a bit unpolished as the sensitivity isn’t tuned quite right to quickly navigate through the tablet.

Of course, there’s more to the controller than just the buttons and controls. NVIDIA has made sure to do things right by using WiFi Direct for communicating between the controller and the tablet. The frequency used depends upon what access point the tablet is connected to, so it can switch between 2.4 GHz and 5 GHz as necessary. NVIDIA claims that using WiFi Direct instead of Bluetooth drops latency by half, and also allows for microphone input and sound output via 3.5mm jack through the controller. In practice, the controller works great. I don’t have any complaints about this at all. Pairing is as simple as pressing and holding on the NVIDIA logo for a few seconds, then opening the pairing application. Up to four controllers can be paired to the tablet this way, which introduces interesting possibilities for local multiplayer games such as Trine 2. I also didn’t notice a difference in response time of the wireless controller when compared to the wired controller of Shield Portable. It’s incredibly important to get the controller right for gaming devices, and NVIDIA has nailed it. Overall, I’m happy with the basic hardware for both the controller and tablet. While it would be interesting to see a metal unibody design on the tablet, it’s difficult to justify at the price point that this device has to hit.

Of course, while hardware is important, software makes or breaks this tablet, so that’s next.

Software: DirectStylus 2, Console Mode, ShadowPlay

    The GPU is definitely fast, but how power efficient is it? If they've made a GPU that produces 2x the performance at 3x the power draw, then that's not going to be terribly competitive.

    Are there any tests that could validate this? Something like a GPU benchmark performed at a fixed framerate with the screen off?

    One would have to measure at the voltage rails (which is what NVIDIA did when comparing TK1 to S800 and A7). Reply

    Its definitely more efficient. Nvidia claims its 1.4x as efficient. Reply

    Over the years, Nvidia has made a lot of claims that have turned out to not be true. I'd like to see the measurements. Reply

    The technology is cool and it really looks like a premium product, something relatively rare in the android space. However, I'm still looking for a use case. I mean, why would I stream from a PC instead of playing on the PC, if it is in the vicinity? And why would anyone pay serious money for gaming on the go instead of just using a smartphone for the few moments were mobile gaming might be interesting. And, if someone really needs to game on the go, 2.5h seems too few...

    Anyway, the technology is really nice and the execution is quite good. If I were in the market for a tablet I would think about it. Not tempted to upgrade, though.

    I have a 1st gen Shield and it's for people like me: someone who sits at a desk all day and when he comes home doesn't want to sit at another desk or use a mouse anymore. I used to hook my mITX PC up to the HDTV and play with a controller, but then when I wanted to play an RTS or an MMO, I would move it back to my study. That's just cumbersome and requires a ton of wires in both locations.

    With the Shield, I can carry it around easily as a handheld and hook it up to my TV in Console Mode to get 1080p game streaming - all while now leaving my PC in the study for good. A couple other great use cases: playing PC games in bed while still being able to chill with my wife, outside enjoying fresh air, sitting on the toilet, and I've even sat on a lounger in the middle of my pool and streamed games.

    If playing PC games in the middle of a pool surrounded by sunshine doesn't sound boss, then I don't know what is.

    Yeah, admittedly playing in a pool does sound cool. You do have a point there. My major obstacle would be paying for the pool, I guess... Reply

    Maybe if Nvidia made a gamepad that was attachable to the Tablet and with good weight distribution. But then the Tablet is much larger though. Reply

    I'm very curious to see the K1 version with two Denver CPU cores instead of four Cortex A15s. Reply

    "There are still frame drops involved in scrolling through lists and similar areas where Android has traditionally struggled to stay smooth, but Android L should fix this issue for the most part."

    I chuckled when I read this. How many versions of Android have promised smooth UI frame rates? Since 4.1?

    MS could get Tegra3 to smooth-scroll Windows!
