NVIDIA Shield Review: At the Crossroads of PC and Mobile Gaming
by Brian Klug on July 31, 2013 12:14 AM ESTGFXBench 2.7.0
While GFXBench 2.7 (formerly GLBenchmark 2.7) doesn't yet take advantage of OpenGL ES 3.0 (GLB 3.0 will deliver that), it does significantly update the tests to recalibrate performance given the advances in modern hardware. Version 2.7 ditches classic, keeps Egypt HD and adds a new test, T-Rex HD, featuring a dinosaur in pursuit of a girl on a dirt bike.
Scene complexity goes up tremendously with the T-Rex HD benchmark. GLBenchmark has historically been more computationally bound than limited by memory bandwidth. The transition to T-Rex HD as the new flagship test continues the trend. While we see scaling in average geometry complexity, depth complexity and average memory bandwidth requirements, it's really in the shader instruction count that we see the biggest increase in complexity.
The fill rate tests put Shield significantly behind the iPad 4 and about on par with the Nexus 10. Looking at Triangle throughput we see Apple hold onto an advantage there as well, although Tegra 4 does show impressive gains over Tegra 3.
It's really in the pixel shader bound tests that Tegra 4 really excels:
As promised, Tegra 4's GPU manages to outperform the iPad 4's PowerVR SGX 554MP4 in GFXBench 2.7. The 50% performance advantage is appreciable, and should be very nice on a high res display. It's a shame Shield is stuck with a 720p panel. Note that we're also half way to the performance of Intel's HD 4000 here. The Adreno 330 comparison is, once again, extremely close. Qualcomm pulls ahead by 8% and that's without a fan in a tablet chassis.

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.
