NVIDIA Shield Review: At the Crossroads of PC and Mobile Gaming
by Brian Klug on July 31, 2013 12:14 AM ESTCPU Performance
Tegra 4 features the fastest ARM CPU configuration of any device we've ever tested. There are four Cortex A15 cores inside running at up to 1.9GHz. Note that 1.9GHz is the max CPU frequency even with all four cores active. Tegra 4 is an absolute beast. Do keep in mind that the Tegra 4 is actively cooled via a fan inside Shield, which does give it a bit more thermal flexibility than what we'd normally find in an Android tablet.
CPU-Z incorrectly identifies Tegra 4 as Tegra 2, the cores and frequencies are accurate though
Looking at even our limited CPU performance suite, the combination of ARM's first 3-issue out-of-order architecture, incredibly high clock speeds and a big chassis to dissipate heat is extremely evident. SunSpider performance is in downright low-frequency Core territory, and it just blows away anything else we've seen from any device running Android or iOS. The comparison in Google's Octane benchmark is still strong, although the Nexus 10 comes very close. Finally, we see great performance in Kraken as well. It's a shame we haven't seen Tegra 4 used in more places, because honestly this thing could make for a killer Windows RT device.
I threw in some of our early Snapdragon 800 performance data, and it looks like Tegra 4 still pulls away with a win in that comparison as well. ARM's Cortex A15 is just insanely quick. Again, there is a fan in Shield - that definitely helps make this possible.
For what it's worth, there's no funny CPU clock boosting going on upon launching any of these tests.

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
