NVIDIA Shield Review: At the Crossroads of PC and Mobile Gaming
by Brian Klug on July 31, 2013 12:14 AM ESTBattery Life
NVIDIA's Shield includes a 28.8Wh battery, which is large for a device its size but small compared to what you'd find in a 10-inch tablet for example. The good news is that it only has to power a 5-inch 720p display, which makes the choice of battery size quite nice. Since Shield is a fully functioning mobile device, we put it through our current battery life suite. Normally we'd start with our WiFi web browsing test, but given the target market for Shield I figured starting with our 3D rundown test made the most sense.
Here we have a loop of the Egypt HD benchmark, capped to 30 fps, running on all of the devices with their screens calibrated to 200 nits.
Shield manages just over 6 hours of use on a single charge, putting it up there with some of the best mobile devices we've put through this test. Being able to support 6 hours of locally rendered gaming without plugging in is pretty decent I'd say.
Video decode is also quite important, especially when you consider the use case where Shield acts as a remote display and controller for games rendered on your PC. In that case, the GPU is mostly powered down and only the video decode block is used to display what's being rendered on your PC. Our video playback test might be a good simulation of this use case. Our test remains unchanged from previous tablet reviews. Here I'm playing a 4Mbps H.264 High Profile 720p rip I made of the Harry Potter 8 Blu-ray. The full movie plays through and is looped until the battery dies. Once again, the displays are calibrated to 200 nits:
Tegra 4's video decode engine combined with a tiny 720p display and a 28.8Wh battery results in awesome battery life here - almost 19 hours on a single charge. If you can deal with the small screen, Shield might make for a good companion on long haul international flights just for video playback.
Finally we've got our standard web browsing battery life test:
We regularly load web pages at a fixed interval until the battery dies (all displays are calibrated to 200 nits as always). The differences between this test and our previous one boil down to the amount of network activity and CPU load.
On the network side, we've done a lot more to prevent aggressive browser caching of our web pages. Some caching is important otherwise you end up with a baseband/WiFi test, but it's clear what we had previously wasn't working. Brian made sure that despite the increased network load, the baseband/WiFi still have the opportunity to enter their idle states during the course of the benchmark.
We also increased CPU workload along two vectors: we decreased pause time between web page loads and we shifted to full desktop web pages, some of which are very js heavy. The end result is a CPU usage profile that mimics constant, heavy usage beyond just web browsing. Everything you do on your device ends up causing CPU usage peaks - opening applications, navigating around the OS and of course using apps themselves. Our 5th generation web browsing battery life test should map well to more types of mobile usage, not just idle content consumption of data from web pages.
Once again, excellent battery life from Shield.
NVIDIA ships Shield with a 10W (2.1A) power adapter, capable of completely charging Shield in 5.45 hours:

I won't comment on the Ouya but it's not really true that the Shield has the CPU power to go beyond existing Android platforms.The Shield still doesn't have sufficient power to emulate the PS2 so it's limited to PSP, DS and N64 class emulation.
But the Snapdragon Pro already has sufficient power to emulate those at full speed (in fact, it's insufficient software optimization that holds back emulation performance). Actually even quad A9's can do it.
So the Shield is stuck at a halfway point where it doesn't offer greater emulation capabilities despite being more powerful.

Your comment seems contradictory to the CPU Performance section in the review, e.g. than not even Snapdragon 800 (itself significantly faster than Snapdragon Pro) can keep up with Tegra 4 in terms of CPU performance. Care to elaborate on your claims?Arbee - Wednesday, July 31, 2013 - link
Yes and no - it can do the existing platforms at a much higher degree of fidelity than the existing emulators, and it can run (ARM ports of) the best-of-breed PC emulators for those systems like bsnes and so on. It can run real current MAME instead of the gimpy circa-1999 "4All" version, it can run bsnes/higan instead of snes9x, and NEStopia instead of I don't know what. That in itself is a great upgrade for accuracy snobs like me, and then combine it with decent controls and it's great.I agree that a similar device with a Snapdragon Pro or Apple A6 wouldn't give away much in the performance department, but nobody's making one. Meanwhile, FedEx just showed up with my Shield :)

Sorry if I missed it, what are the minimum hardware requirements for the gaming PC to stream to Shield? You used a pretty beefy system that is definitely not representative of the average rig out there.PNN - Wednesday, July 31, 2013 - link
Nvidia GTX 600 series or newer is required.ssiu - Wednesday, July 31, 2013 - link
Pretty beefy hardware required. From http://shield.nvidia.com/play-pc-games> GPU: GeForce GTX 650 or higher desktop GPU (Notebook GPUs are not supported at this time)
> CPU: Intel Core i3-2100 3.1GHz or AMD Athlon II X4 630 2.8GHz or higher
> System Memory: 4GB or higher
> Software: GeForce Experience™ application and latest GeForce drivers
> OS: Windows 8 or Windows 7
> Routers: 802.11a/g router (minimum). 802.11n dual band router (recommended).

Apple has trademark the term Retina Display. Thus nvidia can not use itspigzone - Wednesday, July 31, 2013 - link
Likely developed as in in house remote terminal for the Steam Box, where it would actually make sense, it's release into the wild indicates Nvidia ultimately lost to AMD to provide that hardware, likely due to publisher/developer pressure to go with a console compatible solution an AMD HSA APU that they could port to easily and cheaply.chizow - Wednesday, July 31, 2013 - link
Looks like an impressive first effort by Nvidia, especially since it's almost 100% home-grown. Not interested in it for my own user however, not yet anyways, for the reasons below:1) Android gaming market just isn't enough on it's own to justify this for me. Phone and tablet are enough atm for minor gaming on my mobile devices.
2) I did not see any mention of this being used as a Windows Media Extender. If this were able to function as a streaming device, even for DLNA compatible devices, that would be a huge plus for SHIELD. It already has the mini-HDMI output and wireless capabilities, would just need the software.
3) PC streaming to local network connection is nice, but if this could be expanded to remote locations with sufficient network connectivity, I'd be sold instantly.
Overall I think Nvidia is building an impressive track record with their in-house hardware designs, I'm really hoping Shield does well enough that it warrants a 2nd iteration and improvements, but right now, I'm really not sure what it's future holds for many of the reasons cited in the article.

There are DLNA applications for Android in the Play Store. I don't know how well they function, but perhaps one or more of them might work for you. Alternatively, if you run the Plex media server, their Android app *is* good.
