Force GPU rendering...

To enable, or not to enable.. What do you guys think and why?

Why would you want to?

Well I read mixed information about how it could benefit how your apps run.. Just wanted some other opinions

Not really sure. On the Galaxy S, forcing GPU rendering yielded marginally better performance and battery life. You could assume that any graphical rendering is best left to the GPU, and as such you'd get better performance and a quicker return to sleep. However, the CPU could be enough (combined w with a power-hungry GPU) that it's more efficient to let the CPU render when it can. Only time and experience will tell. I have it enabled.

Isn't the new N7 the same spec as the N4?

Isn't this just practically the same spec as the N4? Same CPU, same amount of RAM, GPU etc. etc.?

Yes

With a better display resolution ofc. Is that a good thing or a bad thing for you? Because I think It's awesome to have a tablet like that at this price tag. I'll refresh my Nexus 7 with the new one as soon as I can since it's extremely affordable.

I have a Nexus 4, no Nexus 7. Have an iPad 3 but want something more portable so don't know if I should get the new N7 or wait for an iPad Mini update. Tied into both ecosystems, but if I go all Android, there's a lot of money wasted on iOS apps.
Also, how do you change names? My girlfriend set this up but doesn't use the account anymore - or is it best to just start a new account?

You can either use multi-user functionality or detach current Google account from tablet and set it up with a new one again.
Nexus 7 is also really portable. It fits into my back pocket and I'm going to everywhere with it without any hassle. iPad 3 in the other hand it's a gigantic device compared to Nexus 7 because it's bigger than 10" and also it has a 4:3 display makes it even more harder to carry around with ease.

So can one use the Steps to Flash the Android 4.3 Build [Clean FLASH or Retention of Data /w Flash], for the N7? IOW: Will this N4 procedure work on the N7?

This thread is discussing the new nexus 7, however many nexus operations are similar, so I don't see why it wouldn't work. Just make sure to use the proper filenames for your device.

You could try asking an admin, but your best bet would be to just create your own account.

I would say yes but this devicenis more capable. I know LG is known for thermal throttling on their mobile phone line. Those constraints won't apply to this new device. Its able to run hotter longer. So even if not stock, once Roms come out, this device/processor can be pushed alot more than in a phone.
Btw, I disabled thermal throttling. On my LG optimus G pro with Snapdragon 600 and Andreno 320. It runs great. So the S4 can be easily pushed past stock limits with no problem.

Eh, its smooth enough. Really no lag at all, but then again, I never had the 1st Nexus 7, so I don't know if that lagged at all. Overall, I couldn't care less whats inside as long as its smooth and fast for the user (me). The ipad mini has 1/4 the power of this, and it runs just as smooth.

Snapdragon s4 pro (1.5GHZ) = uses krait 200 cores
snapdragon 600 (1.7GHZ) = uses krait 300 cores
Nexus 4 SOC - (APQ8064) = four Krait 200 cores + 2GB LPDDR2 RAM +Adreno 320
Nexus 7 SOC - (APQ8064–1AA) = four krait 300 cores which are underclocked + 2GB DDR3L-1600MHz SDRAM + Adreno 320
so basically the New Nexus 7 uses a underclocked Snapdragon 600

I read something like this already, but I'm a bit skeptical about it. Why would Google advertise the lower spec than they actually are?
If this is true, than it's a gamechanger as krait 300 cores are some 30-40% faster than their older (krait200) brothers.

Yea we have an underclocked S4 600. So its faster then the N4. Also the memory bus has been increased.
The N72 is faster then the N4 but probably nothing noticeable right now. Perhaps with KLP, the additional memory bus and newer CPU instructions might distance the N72 further away from the N4, but who knows.

S600 after all ?

Post on Gsmarena:
"The motherboard has a Qualcomm Snapdragon S4 APQ8064-1AA chipset, which as it turns out is a downclocked Snapdragon 600 chipset – four Krait 300 cores (rather than Krait 200) at 1.5Ghz and Adreno 320. There are also four Elpida 512MB RAM chips, SK Hynix 16GB eMMC storage, a Wi-Fi a/b/g/b and BT4.0 capable Qualcomm chip and an Analogix SlimPort transmitter."
PS: Sorry if this piece of info was clarified somewhere else in the forums, I did not found it.

Yes it is a downclocked s600 which comes with krait 300 and lpddr3 ram.

It's not exactly a 1.9GHz SD600 (APQ8064T, APQ8064AB) downclocked, but a Krait 300 variant (APQ8064-1AA) that is intended to run at 1.5GHz, so overclocking I'd imagine would come with plenty of throttling and battery consumption.
It really is the perfect HW for current generational need, it's not like we can do pro-grade stuff that needs Core i5 power, so it's best using the stock clock which is well balanced between performance and battery life.

I can't imagine overclocking to 1.7 would drain anymore than a percent or 2 of total battery consumption. With the current setup it looks like it can even be done with the same voltage settings to me.

I mean, I'm not the type to OC obsessively. I mean, underclock = better battery... But if we could bump up to "stock" it prob wouldn't be that bug of a difference. BUT apparently this model of the S600 is supposed to run at 1.5. I'll probably keep it there.

On Wikipedia it says that the APQ8064-1AA has a way faster memory speed than the S600 in the HTC One (1600MHz DDR3L 12.8 GB/sec vs. 533MHz LPDDR3 8.5 GB/sec).

Underclocking doesn't necessarily lead to a better battery life. It depends on the efficiency at the actual frequency. If you underclock, the chip needs less current but needs more time to finish the work load because it is slower. So what matters is total energy consumption: W = U * I * t (Voltage * Current * time). So to save energy, the current has to decrease more than the time increases for a given workload. Also we can see that decreasing the voltage (undervolting) also saves energy (in this case we don't loos calculation speed because the frequencies are untouched)

Unoptimized cores?

My nexus lag when playing asphalt 8, when I go to YouTube I saw people with nexus 7 2012 playing it smoothly, I downloaded the Tegra Overclock app, in the core count section it showed that only 2 cores are active, I selected 4 and there was a noticeable increase of framerate and the cover is less hot when playing games so I think normally my nexus uses only 2 cores and they heated up pretty fast while other 2 cores do nothing. I hope this help people that have the problem like me

It is quite normal that only 2 cores are active.
Most games only use 2 threads, making the extra cores useless during gameplay (well, not totally useless. They can still do some stuff sporadically like syncing without interfering with the game).
My nexus 7 also runs asphalt 8 quite fine, but it starts to drop framerates drastically when it gets hot.
If I compare this with my other devices:
- An S2 drops framerate after 10 minutes of playing (but less noticable compared to the nexus 7)
- A Note 10.1 keeps going on full force. And even if it goes into a thermal slowdown (after 1 hour of playing!), it is not noticeable (even here 2 cores are disabled during gaming, the 3rd or 4th core only come online when something else is happening on the tablet, like an incoming mail notification)
Could it be that overclocking makes the Nexus 7 hotter, making it to go into thermal protection quicker (and actually slows down the device)?
Can you try the device without overclock?

I'm using stock and I didn't overclocked it
I really don't know, cpuspy shows that the cores clock at 1200mhz way more than before
Glad that I tried though

They do not have the same processor. They do not have the same cores either.
Simply put the nexus 4 has krait 200 cores. The moto x has krait 300 cores.
The krait 300 cores are faster clock for clock than the 200. They also of course have a clockspeed advantage too.
All of Qualcomms crazy naming scheme aside. The moto x has basically a dual core S600 at 1.7ghz. Think HTC one m7 with two cores. And those two cores run at the their max frequency quite a bit often to boot....

User psx on nexus 4 and compare them
Sent from my LG-E975 using XDA Premium 4 mobile app

Quick summary:
N4: APQ8064 Krait 200 quad core @1.5ghz
MX: MSM8960DT Krait 300 dual core @1.7ghz
2013 N7: APQ8064AA Krait 300 quad core @1.5ghz
S4: APQ8064AC Krait 300 quad core @1.9ghz
S5: MSM8974ACv3 Krait 400 quad core @2.45ghz
(the fact some are S4Pros and some are S600's means very little, it's mostly K200 vs K300)
The moto x / 2013 N7 / S4 are pretty closely matched perf wise, which makes sense as they're all the same platform.
If you jump two steps between S4Pro -> S600 -> S800 -> S801 then there's a fair sized perf change, much less so with a single step jump.
At stock clocks I dont feel my S4 or 2013 N7 are dramatically faster then my N4.
It's merely that the N4 has the shortest battery life of the 3 (both relative and obviously absolute)
If you OC your N4, you could easily catch up in raw cpu power (if you ignore the fact that you could OC the other device too).
I wouldnt be too surprised if a K200 @~2.0-2.2+ ghz would equal a K300 @1.7-1.9ghz, though you'd shorten battery life even more on a already short life device.
If you could magically OC a N4 to ~3ghz, I wouldnt be surprised if it could keep up with the S5, I also wouldnt be surprised if it dies in 5 mins.
The N4 is very disadvantaged when it comes to thermal throttling, since once it hits the heat ceiling it drops like 20% in performance so it doesnt overheat.
You could also do the heatsink hardmod if it was really important, it's a rather easy mod (if you dont mind the fact you need to take it apart to do)
All devices have a thermal ceiling, but the N4 is usually disadvantaged when it comes to that. It's far easier to hit it on a N4 then any other device.
You could also do the qcom dalvik+bionic mod, it improved benchmark scores on my N7 by 15% (but much less on my N4, also I said benchmark and not "performance", it's very hard to quantify general performance/smoothness)
I think there was a F2FS mod for the n4, if there is and it works you could dramatically improve storage speed if you use that.
Finally you could always throw random build.prop mods, placebo effects are always the best as far as cost/performance goes.

Moto has generally simply been spinning for marketing.
The fact of the matter is that the MSM8960DT is basically varient of the APQ8064AB/Ax that has 2 cores instead of 4.
Devices newer then the MX also have similar coprocessors now to offload idle sensor work, it's a general part of the S800/801 platform.
There's nothing stopping a manu from including them with any equivilent quad core soc,
which is essentially what qcom did with their own coprocessors in the S800/801 platforms.
Battery life on it is about equal to it's APQ8064Ax cousins since they're obviously the same cpu.
Depending on the rom/kernel, you can turn 2 cores off on the N7/S4/whatver,
but you cant turn 2 more cores on the MX.

The moto x has a slightly faster cores and clock speed but as there are too less cores it is slower. The reason it seems faster is the software optimizations Motorola have included on the moto x. Things such as optimized dalvik and bionic and using F2FS. If you install these on the nexus 4 i think it will be quicker.

The nexus 4 is just not quicker no matter what you do.
Quad vs dual is irrelevant. There aren't hardly any workloads on mobile that even require four cores let alone max them out. And if you do its going to throttle very quick anyways.
Krait 300 cores are faster period. The moto x is faster period. The hardware is just faster.
http://www.anandtech.com/show/6747/htc-one-review/11
No software optimization or trickery. Krait 300 is just faster. It doesn't seem faster. It's faster.
Krait 200 was already a old core relatively speaking when the s4 pro came out. It is the same core as the last gen SoC in the s3 class devices. Just with a newer gpu basically.
Can't believe people are still having this silly discussion.

Yes krait 300 is faster than 200, around 20-30%. The fact the nexus 4 does have 2 more cores does make it faster and just because "There aren't hardly any workloads on mobile that even require four cores let alone max them out" doesn't mean the moto x is faster ( at least by my definition of the word). The nexus 4 already beats in benchmarks but if the moto x does beat the nexus in things such as UI its because of all Motorola's software optimizations like i mentioned before.

In the majority of benchmarks that moto X wins. It even beats the quad core s600 devices in many of them as well. Even giving up 50mhz on the gpu to them.
Throttling is a big deal. Those chips throttle quicker and their clockspeeds go way down. The moto X spends more time at the highest clocks.
http://www.anandtech.com/show/7235/moto-x-review/7
Overall no matter how you try and slice it. In the majority of use cases, real world and benchmarks. The moto X is faster
And it doesn't beat it in stuff like ui because of some optimization. It beats it because it is a significantly faster clock for clock and has a clockspeed advantage. And browsing around the ui doesn't use for cores on top of it all. You can easily show that on your nexus 4 with a custom kernel and setting it to dual core only.
It's faster because the platform is faster.

What benchmarks are these? I know the motox has great GPU performance (mostly as it's one of the few snap 600 with a 720p screen) but in CPU performance it usually is lower than quad core s600 devices. For example in geekbench. But yes the moto x is faster than many in real world performance but this is largely due to all Moto's software optimizations.

The article tells you what is used in it. Also for the gpu test many of them have offscreen testing as well which negates the resolution difference.
Again it's faster in many cases because the hardware is just faster period. Just as taking a HTC one m7 and a custom kernel with 2 cores disabled would be faster in real world performance as well compared to nexus 4.
Real world performance is not some micro level threaded benchmark test.
