The NVIDIA SHIELD Tablet Review
by Joshua Ho on July 29, 2014 9:00 AM ESTCPU Performance
As the first Tegra K1 device the Shield tablet is especially interesting. For those unfamiliar with the Tegra K1, NVIDIA integrated four ARM Cortex A15r3 variant cores along with a fifth companion A15r3. While on the surface it seems the CPU configuration it’s largely similar to the Tegra 4, there are some substantial differences. On the process tech side, the move to 28HPm adds SiGe source and drains for PMOS transistors, which dramatically improves drive current and makes it possible to bump clocks up to 2.2GHz for the CPU cores. The new revision of Cortex A15 also means that there’s better power management which should help with power efficiency (and thus battery life). The result is that peak CPU voltage drops from 1.4 volts in Tegra 4 to 1.2V in Tegra K1, and peak clocks are higher in the K1 as well.
Of course, the truly interesting aspect are benchmarks, as those will really show the differences between Tegra 4 and Tegra K1. It will also help to establish how Tegra K1 fares against the competition.
Despite the largely similar clock speeds compared to the Snapdragon 800 we see that the Tegra K1 is generally a step above in performance. Outside of Apple’s A7 SoC and x86 SoCs, NVIDIA is generally solidly ahead of the competition. Of course, as a gaming tablet there’s a strong need for GPU performance, so we'll look at that next.

I think the tablet on its own is decent. Although it is very heavy for its size (Which BTW this review does not mention its weight anywhere).The controller is what I end up scratching my head over. In their release photos they show a girl gaming with the tablet, but sitting like 3ft away. As if being that far away would be enjoyable.
One other thing that is not clear, if the tablet is NOT on wifi, will the controller still work? The article makes it sound like you have to be on wifi.

WiFi *Direct* is a straight connection between the tablet and the controller using the WiFI protocol. It most certainly doesn't need a network to work.Stuka87 - Tuesday, July 29, 2014 - link
Hm, ok. But he specifically said it depends what type of wifi network you are on.lmcd - Tuesday, July 29, 2014 - link
That's for the connection band. Meaning that if one of the two Wi-Fi bands is in use for Wi-Fi, then the other one is the one that'll be used for the Wi-Fi direct.halca - Tuesday, July 29, 2014 - link
Really? That's it for the directstylus review section? I'm disappointed. I hoped to see more comparison between the old and new, and compared to wacom's tech on samsung note line.scbundy - Tuesday, July 29, 2014 - link
Shame about the screen, but with my old Nexus 7 broken and me looking for a gaming tablet replacement, this one appears to fit the bill perfectly. Especially since my gaming PC has a 780 GTX. Can't wait to try it out.dabotsonline - Tuesday, July 29, 2014 - link
"In essence, this device is already ready to serve as an Android TV device."I thought that Google are mandating a very specific UI design for Android TV devices - one which is very different from this? Do you have any inside info regarding the final version this fall / autumn, Josh?

I think he means nvidia can eventually add an android TV mode when connecting via hdmi just like you can get a console mode.SpartyOn - Tuesday, July 29, 2014 - link
Personally, I love my Shield Portable (or whatever they're calling the 1st Gen device). Sitting in bed or on the couch streaming the game I just turned off at my desk is fantastic. It's also the best Android emulator device out there.The recent updates to allow outside the home streaming (which this article incorrectly states as only allowing in-home; please change) and 1080p Console Mode streaming via wired Ethernet, have made this a killer mobile gaming device. Instead of carting my mITX build back and forth when I want to play a game via controller on my HDTV, I can now simply hook up the Shield and stream the game, in full 1080p, to the TV and can hook up an XBOX 360 wireless controller with USB OTG. No more hauling a computer around the house or having to settle for a laptop! Seriously awesome.
My wife and I continuously fight to use the Shield when heading to bed, she for her emulators and me for streaming from my gaming rig. I REALLY want to pick up another one so that she can have her own, so I was hoping this was going to be a self-contained device like the 1st Gen, just with the K1 and maybe some weight balancing, an extra miniUSB port, and a 6" screen with less bezel (the bezel with the 5" is HUGE and I'm sure they could creatively get a slightly bigger screen in there).
Unfortunately, the new Shield device as a tablet is... underwhelming. Sure it has snazzy bells n' whistles for a tablet, but with the larger form factor and lack of handholding ease, this really kills a lot of its portability. I prefer the fully contained controller/screen of the original; plus, it was different and really created a new market. Now it's just another tablet in a crowded field. Seems like a dumb strategy to me.
Until they release a refreshed Shield Portable with the K1, I'll be keeping my money. Kudos to NVIDIA though for the 1st Gen device - I love it.

Unfortunately, you're probably in the minority at this point and I do understand why some would prefer it that way. One of the reasons I didn't get the original shield is because you couldn't do much else with it besides gaming. Even though I loved the hardware and software, I wanted something that could encompass more. Something I could use for both work and play on mobile. The new Shield Tablet fits that almost perfectly.
