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 guess it depends on your setup or what steps you're willing to take. I have an Asus Z77 wifi mobo so I use the Asus Wifi Go app a lot, which allows me remote desktop access and mirroring in an easy package. Haven't invested in a Bluetooth mouse or keyboard, but using USB OTG has worked out just fine for times I've hooked the Shield up to a monitor with M&K.I've done some video editing in Adobe Premiere remotely this way, along with working with Excel files, so I'd say it can actually do work just fine. Does it require some additional cables/accessories to maximize that professional potential? Sure, but then again, I'm not going to be doing any serious work on an 8" Shield tablet without hooking it up to a monitor as well.

Much of the activities I do require me to be away from the home so a shield with a gamepad attached to the screen would be a bit awkward. The tablet fits more with my requirements.SpartyOn - Tuesday, July 29, 2014 - link
I think there's room for both devices for those that buy into the Nvidia brand and who understand/utilize the gaming features; however, the tablet space is a very competitive market for Nvidia to try and enter, with numerous players, especially for work and professional devices.An additional thought on the gaming side, since this really is the target audience: Does it pass the eye test? If I'm a gamer, and I see someone with a 1st gen Shield, I immediately know that it's a gaming device and might inquire what it is. I also can look at pics when shopping and know that it's a gaming device. If I see someone using the 2nd gen Shield, I just see another tablet out in the wild and when shopping online, it would have to come down to specs/features comparisons.
I guess the overall point I'm trying to make is this: the original Shield was so insanely different that over time it had a chance to succeed, especially with yearly refreshes. Now it's just another tablet that can't even stand up on its own (literally and figuratively) ... how do I balance a tablet in bed or on the couch (or in a plane, train, car?!) when I have to fiddle with a controller and the screen itself. Seems cumbersome for gaming to me and in my opinion actually makes you MORE tethered to a stationary external monitor/HDTV instead of the handheld.

If there is enough demand for another Shield1 type device, then you may yet see it, but from what's been gathered, there wasn't. Although I do find it also an interesting device, the gamepad agnostic nature of the Tablet gives a better experience with 3rd party pads. Some of which are attachable albeit a bit weight slanted. And it gives console mode an advantage of not having to use another controller.aamir147 - Tuesday, July 29, 2014 - link
I believe the tablet is just another addition to the shield family, this is not to replace the shield portable. This is what the mod in the nvidia blog said.savagemike - Tuesday, July 29, 2014 - link
It would be trivial to make a frame to hold the tablet and controller together for use as you'd like. Meanwhile I was never attracted to the first Shield because gaming is not my number 1 interest - just something that would be a nice bonus.What I'm saying is this more modular approach could easily be made to work as the original Shield but the original Shield cannot be made to work as a stand-alone tablet. So for me this is a much better design.
Especially with the advent of 3d printing. It will only take one clever person to design something to hold the tablet and controller together to mimic the original. If you don't see it pop up soon for easy purchase then it isn't that wanted as it would be simple to do.

I think you should consider the directstylus modes. I'm sure the wife (if the tablet isn't too heavy) would love that. lus she could read and do other tablet stuffs... if she can get around the horribly dull screen ofc.schizoide - Tuesday, July 29, 2014 - link
You can pick up a refurb Nexus 7 (2013) for $140 from an authorized seller on eBay, or $230 full price and new. The shield tablet costs $300. What do you get for twice the money?From a tablet perspective:
- Slightly larger, but lower quality screen
- Stylus
- Dramatically improved speakers
- 28% heavier
- Maybe slightly snappier? Much faster in benchmarks, but the Nexus 7 2013 is fine for browsing and tablet stuff. I haven't seen anyone compare them in interactive use.
From a gaming perspective:
- Shadowplay, if you have a nVidia GPU in your gaming box and want to plug a tablet into your TV. Better off getting a haswell chromebox and installing steam for linux on it.
- Grid streaming, if you're in northern california.
- A couple Tegrazone games, primarily 10 year old PC ports.
- All the android games built for the lowest common denominator that play on your Aunt's Galaxy S2 will play here too.
In my opinion, the Shield tablet doesn't make a lot of sense as a tablet or as a gaming device. If it was priced competitively with the new Nexus 7, then certainly it would be interesting. If you want to buy a small android tablet and don't care about the $70 (or $160 for the refurb!) I guess go crazy. But will they sell a lot of them? No way.
Now if nVidia could get something like their GTX 860M and crunch it down to fit in a tablet TDP, and slotted it in alongside an atom CPU for a tablet running real Windows, with its massive software library, that could be truly attractive.

Shield tablet is already #5 in the Amazon.com best sellers list for tablets: http://www.amazon.com/Best-Sellers-Electronics-Com...Nexus 7 is a great tablet too, but the difference in SoC performance is quite large. Shield tablet has 2x higher CPU performance and 3x higher GPU performance in comparison, with a much more modern GPU too.
Note that many of the people getting the Shield tablet are upgrading from the original Nexus 7 tablet, so the difference for these people will be like night and day.

Yeah, it's beating the ipad air and mini. It just came out. You think that'll hold up?
