Power Consumption and Thermal Performance

In order to see what the power and thermal characteristics of the SHIELD Android TV are like, the device was tested in two scenarions:

  1. 1080p60 HDMI output to Pioneer VSX-32, connected to a Sony KDL46EX720 46" 1080p TV. Connected to a wired network, with a Samsung T1 SSD hanging off the USB 3.0 port
  2. 4Kp60 HDMI output to a Samsung HU6950 40" 4K TV. Connected to a wireless network, with a Samsung T1 SSD hanging off the USB 3.0 port.

The table below summarizes the important power consumption numbers.

NVIDIA SHIELD Android TV Power Consumption
Activity Avg. Power (W)
Idle (Scenario 1) 3.6 W
1080p Netflix Streaming (Scenario 1) 4.6 W
1080p YouTube Streaming (Scenario 1) 4.7 W
Kodi Playback (Hardware Accelerated 1080p60 H.264) (Scenario 1) 6.5 W
Kodi Playback (Software Decoding 1080i60 VC-1) (Scenario 1) 10.4 W
   
Idle (Scenario 2) 4.2 W
4K HEVC Playback (Scenario 2) 9.1 W
4K Netflix Streaming (Scenario 2) 10.3 W
Gaming (Scenario 2) 19.4 W

Since the gaming scenarios stressed the at-wall power consumption heavily, we decided to run the GFXBench battery life test which puts the T-Rex benchmark in an infinite loop. After 2 hours, we took a thermal image of the unit (oriented vertically with the SHIELD stand).

The thermal solution is excellent, and the frame rates were consistent across all the benchmark runs. Thanks to the low-power SoC, the chassis temperature was just 34 C (ambient at 23 C). The fan noise was audible only when we kept our ears against the vents in the back panel.

Moving on to the business end of the review, we split up the positives and negatives into two sections - one for Android TV itself, and the other for the SHIELD.

    The question is not a matter of capablability but of utility. A $20-$30 chromecast does most of the functions. A smart TV by itself can do some. The Shield is a luxury device. Using nothing or a Roku on bottom to a ps4 or a htpc on top. Fitting in the middle and attacking a niche is this product.
    What does the more capable processor provide I've alternatives and am I willing to pay a little more for significantly more capability? That's the value question.

    "Though it’s a bit of circular logic to say that NVIDIA is intending to exploit these same advantage in the SoC space as they have the desktop space – after all, Maxwell was designed for SoCs first – Maxwell’s capabilities are clearly established at this point."

    There's a difference between circular logic and redundancy (much like there is a difference between circular logic and a tautology). To say that NVIDIA is intending to exploit the power-efficiency in the SOC space is simply redundant after you already said that NVIDIA designed the architecture that way in the first place. The citing of power efficiency in desktop products is simply giving evidence of power-efficiency. There's no implication of EXTRA power efficiency more than what was originally designed in the architecture by moving from desktop GPUs to the SOC GPUs. How can circular logic appear when no implication is being made?

    "Ultimately it’s clear that the SHIELD Android TV is heavily overspeced compared to other Android TV devices – no one else is pursuing this premium market..."
    Perhaps because the market isn't large enough to justify a product aimed solely at it? Nvidia can leverage their streaming GPU stuff and a bunch of other stuff no other players really have.

    Even with that, I don't think the market is large enough to support one player.

    If I use a receiver and send the audio via bitstream to the receiver, will it play or not? I don't see why bitstreaming of audio requires a license? I thought the license is only required to actually decode the audio on the device and play some downmixed version of it.

    Try convincing Dolby, DTS and NVIDIA together :) I am with you on this one, but NVIDIA says licensing is the issue.

    How does it handle external storage of apps? Android has typically been OK about reading media from an SD card, but it's recently been more and more restrictive about how apps can interact with external storage. Does Android TV (or some Nvidia custom magic) solve that problem? With only 16GB internal (and surely less user accessible) it will quickly run out of room if you want to install games. Recent experience with an Xperia Z3 and Nvidia Shield Tablet have not been promising on this front, at least without root access. The Xperia will copy some data to the external storage device, but still leave some on the internal, and the Shield Tablet is really picky about what games it will transfer to external storage. I'd want to just plug a 2TB portable drive into this thing, have it install everything there, and never think about it again, but based on past experience I'm worried that won't work.

    I know they want people to use GRID, but until data caps go away that won't be practical in many places.

    The SATV can handle apps on SD cards. In fact it has a feature to automatically move newly downloaded apps to the SD card in order to better utilize the space it provides.

    Application support is going to be the biggest item. Will it be updated to run current Amazon Prime, Max Go, HBO Go, CW streaming, etc.

    Currently none of the Android TV type devices have parity to the number of streaming video apps that my phone does.

    I didn't have much interest in this product or any of the previous Shield products, but with Windows Media Center's impending doom with Win10 and the prospect of Silicon Dust's HD HomeRun DVR as a viable replacement, I may have to look into getting one.

    It certainly seems to pack a lot of value and possibilities into a very small price tag of $200. I'm just not sure on the naming/branding, but I guess they think the Android TV aspect may have a higher demand than some of the gaming initiatives they are slowly building upon.

    they really should make a $150 version that is just the console. Probably would increase sales quite a bit... Although, the controller and stuff is probably well under $50 to make however.
