I am looking to buy a tablet I come across 2 tablets which have intrigued me the xperia z3 compact and the nvidia shield k1. I liked them both for the specs and low price. The tablet will be used for surfing the internet, youtube, Facebook, games, watching movies things like that so I was wondering if someone who has both or has had experience can recommend me which one is better or if there is another tablet that is better suited for me.

I bought the Shield yesterday because I want to play games with.
But If I was not in this situation (more video/internet/app usage) I will definitively go for the Sony because despite the smaller battery she has better battery life and not a little it's like 10 hrs more in certain condition so very well optimized rom from sony.
But maybe I can fix the shield battery with a custom rom will see
The z3's bottleneck is the GPU.

If you set the Shield power mode to just 2 CPU cores, you'll get much more battery life.

And the shields interface remain smooth?
No problem for watching video and stuff or it start lagging?
It still runs smooth. You may sense a difference with highly demanding games. Or when you transcode videos.

thanks you for all this information
You cannot disable cores on the k1. You can verify this with cpuz. Also the z3 compact tablet has a terrible processor combo by today's standards and doesn't come anywhere near the k1. It also does not have nvidia specific games, console mode, or gamestream (although this can be done with a 3rd party app call moonlight streaming). The speakers are also not as good and it will probably never get another update, ever. There is no reason to buy the sony tablet over the shield.

Then cpuz is apparently showing wrong data, I'd say.
Plenty apps have compatibility issues with a myriad of Android devices.

Unfortunately cpuz is accurate and you cannot disable any cores on the shield tablet, despite what the UI might be telling you.

Ill run antutu for you right now, 2 and then 4 cores, and post the results. I assure you the cores will all be active no matter what. They are always firing no matter what you do.
The benchmarks do indicate that there is a performance hit, surprisingly. I ran a total of 8 benchmarks to be sure. I am not sure exactly what is happening, but the cores are not being turned off, that's for sure. You can verify this with any CPU monitoring app, I tried 5 different ones and they all said the same thing. I think maybe when you force the CPU into 2 core mode, it may under clock two of the cores or something, but not disable them. It's helpful to know that the option at least does something and is not just there and fake lol. However like I mentioned in another post of mine, setting the performance mode to custom to enable only two cores, will perform worse for battery like than just using optimized. Forcing two cores for individual games, might be helpful however, but probably not by much. As you can see from the following benchmarks, the scores are not halved by disabling half the cores, they are only slightly reduced. Not exactly sure what's going on, but may look into it further in the near future.
Benchmark 1 - two cores enabled:
CPU: 18378
Benchmark 2 - two cores enabled:
CPU: 18374
Benchmark 3 - four cores enabled:
CPU: 22660
Benchmark 4 - four cores enabled:
CPU: 22409

Under what kind of conditions would that be? Engadget's review says 13.5 to 14 hours for their continuous video loop test, and they estimate 10 hours in "real world" use conditions.
https://www.engadget.com/2015/01/11/sony-xperia-z3-tablet-compact-review/
I get around 7 hours of screen-on time with my Shield, running stock and not messing with the cores.
The Sony tablet's battery life is impressive, for sure. But to say a 10 hour difference, is probably an overstatement.
This thread makes me wonder (yet again) where are the tablets? I know the tablet market is pretty stagnant, but its still a bit ridiculous that we are sitting here comparing a tablet from 2015 versus one from 2014. NVIDIA shelved its plan to update the Shield tablet this year. Not much else on the market. On the higher end, Samsung neglected to update its Galaxy Tab S2 this year.

So under what circumstances will you switch to 2 core mode to save battery? The tablet has great battery until it fires up a game and there's not much you're going to do about gaming battery life.

Switching over to 2 cores during a movie will likely cost you battery due to the fact that the minimum clock speed for custom is much higher than the minimum clock speed for optimized.

i checked this during heavy gaming
The 2.1ghz cores appear nowhere
I'm not convinced you understand how this works.
Let me ask you a question, if the other cores "worked", would you notice ANY difference in your game? The answer is no. Why waste more power to do the same thing?

The lower cores of 1.5 are used for more mundain things and lighter usage. The higher cores of 2.1 kick in for more demanding activities such as heavy multi tasking. Gaming etc

To further what reubenskelly1992 said, 4 of the cores are optimised for lower power usage for general day to day tasks (think of a laptop, all nice and cozy, not doing too much because it's for on the road shizzle), and then you have the other 4 cores which are for beasting it through intensive workloads like games (think gaming PC, "Ecofriendly?!?!?! Energy conservation?!?!?! I GOT ENEMIES TO KILL!!!!!"). I had an Alienware laptop once that had two graphics cards. For much the same reason. An intel one for low energy, high battery life for when out and about. And an Nvidia card which I could switch to with a macro, to say good bye to power savings, hello frame rates!!
might have some thing to do with the governor also think its set to interactive as my s6 edge was set to that but rooted it and changed it to performance and the a57 kick in alot more
Ondemand is worth a try too
I bought the phone today, but I think it's way slower than it should be. I know that the LG G Flex 2 has a Qualcomm Snapdragon 810 with 2.0 GHz quad core and a 1.5 Ghz quad core (octa core) CPU, but after i have runned a couple of benchmark tests in Antutu, I got a score between 35000 to 40000! That's way slower than Samsung Galaxy S5's Snapdragon 801! I thought that it whould get a score over 50000 When I see info about my CPU in Antutu after bemchmark test, it stands that the first four cores has a frequency of 1.5 GHz, while the other four cores has a frequency of 0.9 GHz (two of them are "sleeping" a lot)! Is it possible to fix that? I hope so. I've got the 16GB version with 2GB of DDR4 RAM. The device is upgraded to 5.1.1 Lollipop. (Sorry for bad English, I'm from Norway)

i got mine at Tuesday. I can pretty much say i never experienced a lag before even tho i had many apps in the recent apps tab and also i was playing high quality games and it got a little bit hot but still it was working flawless, very very fast. What i did after i updated to 5.1.1 i did a factory reset, then i downloaded only the apps that are indeed from lg apps such as calculator downloads quickremote (because most of them are useless and slow down the phone) and then i downloaded a custom launcher and greenify. Also use the google keyboard from google play store. better to use google's apps rather than lg's. Since then i never experianced any lag before. try it out. If u need more help tell me
That is really low. Go into settings and into battery saver and check if you maybe turned it on, and also see if you checked option to optimize battery in games.
Try restarting the phone and run antutu again, after a couple of minutes..

You are from a cold country so it should help. First try let rest the phone and launch antutu when it's at room temperature.
Then try with an ice pack on the back. It can be ice pack for injuries (kind of thick gel in plastic bag) or for cool box or ice chest, whatever you call it. But don't use it too long, you may have condensation inside the phone and it will trigger the humidity sticker (for your warranty).
Don't launch antutu after a reboot, as it's warm after a reboot. Or reboot and let it cool down first.
It has come to my attention through benchmarks that my CPU is not performing anywhere near where it should be. It also has a -1C reading on Core 2 (technically the third core) in Synapse that occasionally flickers a temperature that is MUCH lower than the rest of the chip (like if the rest of the chip says 70, it will say 40 and it idles at 27C while the other cores don't go below 33C).
My AnTuTu is 62k and my AnTuTu beta is only 76k. In the AnTuTu beta, even the One M9 is destroying my chip (I only beat it on RAM score, Multi-Core, and 3D) - the UX scores are all about 25% under the throttled Snapdragon 810 and in the beta, the Note 5 should score almost 84k. The only benchmark that my phone is beating it on is the 3D benchmark (14602 to 13929).
If my CPU IS damaged... How on earth would I even go about getting T-Mobile to understand what I'm talking about? I mean the phone performs admirably anyway but if this isn't the performance I should be getting, I don't want to have a defective phone...

Is your phone working properly when doing phone things? Is it modified?
What software version are you on? Kernel?
We need all that.
By the way......scores don't really mean anything as It's a cellphone, not a gaming rig but understandable people want to test performance. Do you use your device mostly fire gaming? If so do you get any lagging dieing play now compared to before?

Hello,
It's been 10 days that I have a Z5. After testing all, I told myself I was going to test the core of Snapdragon following the "problems" of the z3 +.
I am quite troubled. I use Folding @ home to test the operation of cores. The 8 cores It Works together have only a few seconds. 6 core (4 A53 and A57 both) Few minutes. And after-3 minutes, only 4 A53 and 1 A57 at 800mhz Work. In games it is a bit the same. To this are normal ? For me it is not a true OctoCore. Do you think there will solutions to force the use all core ?
Thanks

In simple terms; it is down to the app to decide how many cores to use. The app is programmed in such a way to utilize X amount of cores. When you run older apps what were written for 1 and 2 core processor phones they will use 1 and 2 cores.
So yes, not using all cores is normal. When everybody is using an octo-core processor phone, apps will use all 8 cores at the most efficient level.

Thanks to you answer. But i kown that. Folding is an app that use all core. I think Sony quickly disables core to avoid overheating. For me it's not normal. Z5 never use 8 core more than few secondes

Antutu will use all cores available to it but try running successive benchmarks and you'll soon notice that the scores drop lower and lower as the phone heats up. Now I don't know if cores are being disabled or the clocks are just lowered but either way, you can't use all 8 cores at full speed for long...

Yes agree. i'm slightly disappointed on this point. That all ^^
See now I just recently got the Z5 over my half broken z3 cause it's a 8 core vs the 4 core in the z3, but even with Antutu it only uses 4 cores, even when they're completely maxed out. I've pretty much gone from a 2.5 ghz cpu to a 1.5, it is they programs are not reading it or they're just not being used?
It's kind of infuriating really, if they won't be used ever I will send it back and get a higher clocked 4 core cpu phone.
Some times core 4 is used, slightly, would a custom rom be able to fix the issue with core not being used??
Benchmarking software should be able to max out all cores on a cpu.
Hi,
Need some advice here. Two phones for sale, both same brand/model however two separate specs and I need the one that will draw the least battery as I use the phones screen time for 8 straight hours a day (satnav) so the less battery draw the better. I do not care about anything else!
1) Snapdragon 625 - 14nm but 5.5" 1080p Screen
2) Snapdragon 435 - 28nm But 5.0" 720p Screen.
So the first phone has the newer 14nm CPU however has a bigger screen area (5.5") and Full HD.
However the second phone has a smaller screen area at 5.0" and is running less resolution @ 720 but has the older 28nm CPU which draws more power.
So which setup, in theory, would use less power?

It comes down to usage I suppose. If the task at hand requires a lot of processing power but is less taxing on the screen/GPU then the SD 625 is better. If its the other way around then choose the device with the SD 435.
What about battery capacity, are those the same as well?

Yup both phones have the same battery capacity, they are both identical in most respects, one is the note version the other is not.
The usage is 100% satnav (Waze) no other apps will be running. Any ideas on the usage of Waze?

I'd go for the newer/more efficient 625. As things such as GPS, Mobile Data and WiFi usage are embedded in the SoC. Screen brightness and density can be easily be adjusted to reduce power consumption. And you can also underclock the CPU (or turn on some sort of power saver mode) to squeeze out as much juice out of the battery as possible. The difference between a 720p and 1080 p device isn't that much anyway. But the improvements of the 625 over the 435 is far greater.
