Final Words

If I’m honest, it’s hard for me to review tablets. While I academically understand why people like tablets, I’ve never really found a use for them. They’re less comfortable to use in bed than a phone, I usually can’t type on a tablet as quickly as I do on a phone due to the size and weight, and in general it’s hard to justify a tablet when a phone is generally much more versatile. So when I got the Shield Tablet, I didn’t really know what to expect. While I have a Shield Portable, I don’t spend much time gaming on it, especially when I have a desktop that can do it much better. I came away from my experience pleasantly surprised.

Over the past five days, I’ve learned a lot about this device. As a tablet, it’s good. The material design and industrial design is acceptable and the device itself is quite ergonomic but it doesn’t blow me away. However, given the need to meet cost constraints, the matte plastic feel is really all that’s necessary and I don’t have any complaints in this area.

In the other fundamentals, we see a bit of a checkered pattern. In the display, the static contrast is quite high, and the calibration is good, but the gamut of the display doesn’t cover sRGB. This would definitely be an area that should be improved for the next generation. Although there are some compelling reasons to go with smaller color gamut, it ends up as a disadvantage when compared to other general-purpose tablets. The display is still perfectly usable, but it's a bit more washed out than I'd like.

In battery life, we see that the Shield Tablet ends up doing relatively well in web browsing, but for intensive gaming the tablet can’t spend much time away from an outlet before draining the battery completely. This is likely to be an unavoidable tradeoff, given the immense amounts of performance that Tegra K1 provides versus the power costs of doing so on a 28nm process. Anyone that has lived with a gaming laptop should understand this. As said before, it’s also possible to improve battery life from the 2.5 hour figure if the game is light enough to allow the GPU to run at lower frequencies. Barring that, NVIDIA has included options to cap the maximum frame rate of the display and reduce maximum CPU frequencies.

Otherwise the only other notable difficulty I’ve run into is with the stylus. Generally speaking it works well enough, but the stylus requires a bit more lift between words than I’m used to and keeping it from feeling fully natural. But I will be the first to admit that this is a minor issue at best.

Outside of the tablet itself, the gaming features are compelling. The larger 8” display and massively improved SoC on the Shield Tablet made for a far better gaming experience than what I had on Shield Portable. There’s a great deal of potential in ShadowPlay on a tablet, as while screen recording is nothing new in PCs this feature is often difficult to enable on Android. This is before we talk about the effects that live video encoding has on UI performance. ShadowPlay has managed to enable easy screen recording on a mobile device and do so without significantly impacting performance.

Meanwhile GameStream and GRID are even better on the larger screen that the tablet provides. While it was cool to play PC games on the Shield Portable, the size of the display simply made some elements too small to reasonably see. Now, there are no such issues. GameStream and GRID are definitely a lot of fun to use, especially if the game is well-adapted to playing on a controller.

Ultimately though, I feel that the native game library is the most important aspect of this device. While there are plenty of solid single player games, multiplayer games are few and far between. I still feel that multiplayer is where Shield has the strongest potential because it makes the difference between tens of hours per game and hundreds, even thousands of hours per game. There are definitely signs that this aspect of the ecosystem will improve in the near future as Trine 2 supports local multiplayer and War Thunder on Shield Tablet should be able to play online against console and PC players.

After getting through all of these observations over the past five days, I’ve come to realize that even though it’s not the perfect tablet, all of the features that this device brings to the table right now would be enough for me to seriously consider buying one. If NVIDIA manages to get enough multiplayer titles with an active community on Shield Tablet, there wouldn’t be a need to stop and consider at all. As someone that has spent the past few years never considering a tablet purchase at all, the Shield Tablet is the first ARM tablet that I would seriously think about buying.

The SHIELD Tablet is 299 USD for the 16GB WiFi model, 399 USD for the 32 GB LTE model. Each controller is 59.99 USD and the cover is 39.99 USD. While the 16GB model is 70 dollars more expensive than the Nexus 7 equivalent, the gap narrows to 50 dollars for the 32GB LTE model. Given the sheer amount of utility that this device brings to the table, the pricing is definitely set at the right place.

    I know this is old, but my tf201 with a tegra 3 still plays games great! Uninstalling facebook really helped overall speed!

    The Tegra K1 is lacking an on-chip modem, thus it will always be less efficient than Qualcomm processors, which means we'll probably never see this SoC in a smartphone.
    I think we'll see much more Tegra producs with the K1, because it's really an impressive SoC. But NVidia seems to care less about the typical consumer tablets, more about their own console ecosystem (Shield) and most importantly embedded systems (cars), where NVidia has some huge partners and the Tegra gets widely used. (Tesla, Mercedes, VW, Audi, ...). There they can make more money most probably and don't have to give their IP away for free more or less to remain competive against companies like Mediatek.

    The Snapdragon 805 is also in the same boat without an on-chip modem.

    who cares about the display? I get mine on Tuesday (preordered from Amaizon and picked no rush shipping fo da bling xD) and 90% of the time I'll be using it to play steam games on my TV.

    Just got it. The screen is actually pretty good! Much better than I expected. Great contrast, black level, colors. It's more than good enough for a tablet. I got the original Nexus 7. This is much much much better than that! It looks similar to me to the new Nexus 7.

    No Video playback battery life test?
  • JoshHo - Tuesday, July 29, 2014 - link

    It was definitely planned but there wasn't enough time to finish that test. I'll update the review once I have those results.

    Josh, how about some additional tests using the battery saver mode? Limiting fps to 30fps and reducing CPU clock operating frequencies should dramatically extend the gaming battery life with very graphically intensive benchmarks.

    On a side note, I should point out that not only does Tegra K1 have much higher Onscreen performance in GFXBench T-Rex HD test (which is the test used for battery lifetime and a minimum value long term performance data point) compared to most other ultra mobile GPU's, but is also renders with significantly higher [FP32] precision too. According to Oleg at B3D forum, Kishonti uses low precision FP16 shaders in the T-Rex test by default. Mobile Kepler and other modern day PC and console GPU architectures are designed for FP32 precision and not mixed or lower precision.

    This! It's horrible to complain about the extra dynamic range like it's a bad thing, and then NOT test the battery-saving features.

    Limit the CPU such that it runs like the Shield portable, then set the framerate to 30 Hz and run the gaming battery tests again.

    (On my Surface Pro, for example, I'll set everything to the lowest possible, about 800 MHz, and I'll get a couple more hours out of it while playing games. High-Performance mode is for when you're plugged in.)
  • JoshHo - Tuesday, July 29, 2014 - link

    Those are definitely planned as well, there were some issues with meeting deadlines so battery life testing had to be cut down somewhat.
