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.

Nice review as always and good to see Shield and Tegra 4 finally shipping.I am curious though as to what has led to the (so far) low adoption rate of Tegra 4, especially in contrast to the almost performance-wise equivalent Snapdragon 800. Was it just a matter of time-to-market, or was it deal negotiation issues, or as some say (without providing conclusive evidence) that Tegra 4 is inferior to Snapdragon 800 in power efficiency?
Does anyone have more insights (as opposed to unsubstantiated rumors) into this?

Previously mentioned Amazon reviews for the Toshiba Excite Pro indicate overheating issues and poor battery life. That's not as good as a proper analysis but I'd hesitate to call it unsubstantiated.fteoath64 - Saturday, August 3, 2013 - link
A lot of people are curious about this same question :"Is Tegra 4 is inferior to Snapdragon 800 in power efficiency?". I would agree that it is a yes but not by much. The issue for both chips are that they are overkill (in battery sapping rate) for phone implementation and more suitable for large tablet and console use such as Shield. I think the issue of T4 is its TTM just kills the market opportunity and also the fact that Qualcomm has had multiple solutions to match/counter the old T3 design wins and hence snags them all!. It is a pity for Nvidia but the market is rather brutal due to fierce competition. Even Intel cannot muscle themselves in with the new Atom chip. Not that it is good enough or low priced (huh!). This T4 device at least gives the market some sort of benchmark in comparing its performance in detail over the coming weeks. The S800 tablets are not as forthcoming as we hoped so there is plenty of time to determine some much wanted data.It is interesting to see the SnapDragon S4 Pro chip being used in Nexus 7 and Moto X, new Droid range as well especially when the flagship S600 was doing so well. Is there a radical price difference , I wonder ...

Didn't see it in the review, but I'm curious how well it performs streaming PC game to Shield to HDMI cable plugged into a TV. Cabling get in the way? Problems with battery life in this scenario? How well does the high-res PC compress down to stream to the Shield, then upconvert back to 1080p for the TV? What about transition from sitting on the couch with the cable plugged into the TV, then unplugging the cable to walk into the kitchen, any glitches with transitioning back to the in-device screen?marraco - Wednesday, July 31, 2013 - link
I wish I had a PC client for streaming, so I can run my GTX 670 and play on my laptop/netbookmarraco - Wednesday, July 31, 2013 - link
That would rule out AMD cards for mepandemonium - Thursday, August 1, 2013 - link
I just don't see the point in spending money on a mobile gaming device any more. With all of the smartphones and tablets out there, this is going to be a difficult sell to anyone but the most enthusiastic of fans.Also, my PC is built for gaming and the ecosystem isn't really going anywhere (contrary to popular belief that it's been dying for years and years...). Plus, there's consoles.
It may be awesome, but not for the current day and age. If this came out in 2006, it would've made a killing.

The only comment I have is that when I played around with this at PAX East 2013, the screen mechanism felt VERY flimsy. I'm not sure if it was because of the fact that these were demo units that were (obviously) very used at that point or what, but I felt like if I closed the screen the hinge would make the screen break in half. It just didn't provide a good feel as it closed, like the hinge was too tight. It reminded me of my MSI GT70's screen at times, where I'm very careful closing it since it is rather delicate.All that aside, it did seem like a good device and was fun to use, but I just don't feel I'd use it as much simply because I enjoy having a tablet for real use.

so.. its got a screen, it has speakers, it has a a mic, it has wifi..so it just needs 3g and you can stick it next to your ear and start making calls ?D
