I/O Benchmark results - Nexus 7 General

hi, could someone please post benchmark results of the nexus 7?
I am particularly interested in I/O benchmarks such as Androbench and RL Sqlite benchmark.
I want to know this because Asus is having problems with I/O performance on its transformer line on ICS which causes loads of lag and ANR messages....
thanks in advance

I posted mine here

thanks.
the scores on the nexus 7 are way better than on the prime.
did some research and it seems the nexus 7 uses the same memory as the transformer prime ..

must be a software thing ......

Only thing I can think of is the crap 2.6 kernel on the 201, cause both are stock aside from my cfq scheduler on Prime. I thought the T30 was supposed to be better than the T30L.

yea it must be. have posted this info to motley kernel thread.
found the n7 kernel source in his GIT. maybe he is already looking into it or he is developing a N7 kernel too

he is developing for N7. just take a look at the Nexus 7 original developement section. he already has made a sick motley kernel for this device. overclocked to 1.6ghz. happy to see familiar faces over here also. hopefully we ALL can have a better asus experience here..lol

Any update on this? These are my quadrant, IO are the lowest it seems

Tegra 2 overclocking

I already postet this in the Atrix 4G section, because they have a thread there about this topic. But they are discussing more about the locked bootloader than about overclocking and as we don't have such a thread here, I will start this one.
Perhaps you think overclocking actually does not make much sense on this device atm, as it is really fast, but I always like to get most out of my hardware that is possible.
I dont think, I would enable overclocking for everyday use now, but it would be cool to be able to do so if needed. At 1200 MHz as Nvidia had planned for the Tegra2 3D the Phone would for sure even beat the Omap 4 in Optimus 3D.
I am totaly new to Android and also to Linux, so I am not sure if this is helpful, but I have seen something very interesting in the Optimus 2x review at Anandtech.
I dont know where these variables are stored and what is needed to, but for me it looks as if we are able to change them, overclocking should be possible on the Optimus 2X.
It would be great if some oft the developers here could look into this when the Optimus Speed finally has been shipped…
I was wondering the same thing. So i checked other Tegra2 powered devices. And as far as i know none has been overclocked yet. Correct me if am wrong.
So far no overclock is needed since this phone is reaaaaaaalllly fast.
But I am sure as soon as it needs some extra power developers will figure out how to do it
Michael Huang (author of SetCPU) has just overclocked the Xoom tablet today. Now, while the Xoom is a Tegra2 device, its kernel is (apparently) Google based whereas others are nVidia based.
In overclocking the Xoom from 1GHz to 1.5GHz though, he saw about a 1/3rd increase in performance on Linpack and Quadrant. Looks promising so far.
Watch the video here http://www.youtube.com/watch?v=cLNjHyAi8BI and follow Michael on Twitter here: http://twitter.com/coolbho3k
The Reason to Overclock the Atrix in my opinion is as follows
The Linux Based Webtop is slow in reviews
So when pluged into mains power it would be very usful to overclock the device to make the most of the webtop with less lag issues making the device far more usful if you need/want that feature.
Maby possible to make a custom dock (stick fan on it) and clock higher
I'm more interested in underclocking, especially when screen is off with a screen off profile in SetCPU. What do you think is the lowest possible frequency I could set it at?
You can put all the way down. I use the same settings in both my N1 and the 2x. Saves some juice. What I really want to see is custom kernels, pref undervolted if its possible.
Sent from my LG-P990 using XDA App
According to the SetCPU changelog, overclocking/underclocking is now possible:
2.1.1 - Fixed an issue with profiles backup in CM7.
- Added support for the Motorola Xoom, Atrix 4G, and other Tegra 2 devices.
- Fixed various bugs.
- Tablet optimized UI and more profiles coming soon!
2.1.1a - Fixed the 0 MHz display issue on some devices.

How can you overclock with SetCPU then on o2x? Believe only the powersaving underclocking on demand is working.. overclock needs more work i believe.
The Xoom has been overclocked, but apparently the kernels are from google, which made it easier.
If anybody knows more about this, please correct me
The kernel must be adjusted to make overclock work. I got to read myself into this, but perhaps someone else knows already everything to it .
GPU
i wonder if the gpu can be overclocked, would be nice if it was possible too just OC the gpu and compare the results. Or do you think that the CPU and GPU clock speeds are somehow linked???
Any thoughts?
bumping cause im curious. Can any one please answer ?
well this is arm so id day they are linked
are we able to read the clock speed of hte gpu. does is change?
Look at the date mate
The GPU is not linked with the CPU. The GPU is overclocked in different kernels. Spica's kernel allows on the fly overclocking of the GPU.
After having this device for over a year, the only time i needed OC is for 720P Youtube or Youtube HD app. No OC on the GPU has ever been needed. Yes i have been playing around with 1.2 and 1.4, but they just consumed battery more than giving a better experience. I would go so far and say undervolt it and put it on 900Mhz.

Quadrant and AnTuTu benchmark results

Guys,
Looking for some feedback on stock ROM and Kernel 3G or Wifi Only Dell Streak 7 benchmark scores. I normally think benchmarks are pretty useless, but curious to verify a few things vs a custom kernel to ensure there's no performance losses vs the stock kernel. If there's no problems found, in a few days there will be a custom kernel with CIFS, TUN, etc available thanks to Mashi. Anyone interested in that, please help out with some benchmarks here. The kernel will be in another thread, just some sanity checking of performance here.
So far Quadrant Standard is about where I saw folks in another thread.. 1950ish. i didn't see in there where it broke down the 3D score, as I'm curious a bit about that.
Run it after a fresh boot, don't run it multiple times please.. I hear that really clouds the results because it's just running out of cache, etc..
AnTuTu score for my device is 4750. I'll break down the scores here to compare line by line, if people will help out there it'll be appreciated. Same with Quandrant, if you could run this one time after a fresh boot.
CPU Int: 1095
CPU Float: 982
2D: 411
3D: 1172
Database IO: 365
SD Card: 6.9 write, 9.4 read
There is already a thread like this (For noobs who don't know).

For one, nice URL fail. Second, that's for a COMPLETELY DIFFERENT DEVICE.
Get a clue.

Additional CPU governors

Guys,
doesn't anybody wonder why we only have 2 governors? I googled on how to create one myself and found an example source code, but I don't have the whole android coders kit pro elite 5000
My question, why didn't anybody thought of any additional governor? smartass, interactive, ondemand, conservative, lulzactive and so on...
If anyone is interested I can share the source of the interactive gov...
I hope anyone is able to code a new governor??
Greets
I think it has to do with the governors being hardwired into the Tegra SOC. Correct me if I'm wrong.
The SGS2 has about 10 govs and its also Tegra...dunno though I can be wrong...^^

The SGS2 is not Tegra, it's Exynos and the T-Mobile variant is Snapdragon.
Tegra doesn't accept governors like the other platforms do. Even the 2 you see in e.g. cyanogenmod don't have any effect whatsoever.
yup, rmcc said thait governors don't do anything on tegras.
Aaaaaww maaaan...what a pity...:/
OK I think this thread can be closed then...I'll report it to the senior mods..

As topogigi said, tegra as several governors, but the p990 tegra drivers are bad programmed, so we have only one hw governor. His Xoom as other governors on stock kernel.

whoever topogigi is, he's wrong. 2.6.32 tegra does not use governors, they were introduced into Tegra by Google for HC.

So they are "emulated" governors, right?

I am Topogigi, pleased to meet you. Xoom has Honeycomb by default, another kernel, same cpu. So, I don't really understand what was wrong in my answer. Bad driver in 2.6.32, no effective governors: is that wrong? I was only unsure if actually the two governors that are exposed in userspace (performance and powersave) could have any effect. From your answer, I could assume they have not. Don't still understand the reason why two governors are exposed in userspace, but I will live even ignoring that.
Last line, I'm not so sure why Google should bother writing drivers for Tegra and HC. My guess is that Nvidia did it, but that doesn't matter at all.

Hi there;
It's not a bad driver, it was a stupid design decision by nvidia which google changed for HC (along with the userspace nvrm transport and odm_kit).
The dvfs stuff is implemented and working as intended by nvidia, the intention was just misguided.
The current implementation is Google's (mostly by Colin Cross), as you can easily see by looking at the source history at both nvidia's and google's source repositories, and radically different from nvidia's original work.

Ok, TY very much: this is the end of the story. Now all is much more clear in my head.
My project the vorkKernel has some "pseudo" govenors in it. Basically not a real govenor, only a limiting thing. The powersave and performance govenor is limiting the freqs to 3-4 steps. So Performance 3-4 higher freqs step and powersave 3-4 lower freqs. Govenor is still the same but atleast something, hehe

Overclocking the 8.9 Galaxy Tablet

Hey guys,
Posted under general questions and to my surprise not one reply in a week. So, I'm curious to know somethings about overclocking these tablets. What settings are you using? Have you had any issues with overheating and shutting down?What settings are recommended for web browsing, gaming etc? Let's talk linpack and benchmark testing. Where do you rank and how did you get there? Let's talk SetCPU benchmark scores, what kind of results can you squeeze out out of your device? How does someone pull off 41916.7 MFLOPS?! (Nexus) I'll start......
GT-7310 Running 3.2 / Motley Kernal / SetCPU
SetCPU Scores
Long Bench @ 178ms / Native @ 621.5ms
Linpack Scores
Single thread @ 42.4 MFLOPS / Multi thread @ 83.2 MFLOPS
Obtained running 1504MHz max / 216MHz min
Note: I have overheated and shutdown at 1504 web browsing. At 1400MHz I have had no issues. I see some scores are through the roof. I'm not to familiar with Overclocking and just would like to hear what you guys have to say. Thanks in advance. I may of posted this in the wrong area and I apologize. I would like this to be a thread on the topic rather than a Q & A.
Well I personally run my tab @1200Mhz with -25mV on the 1000&1200 steps, but anyhow, due to the interactive governor the most used setps are 216, 456 and 1200. I don't undervolt the lower test for stability reasons as I mostly work on the tablet so I don't want to test yet how low uV can go, don't have the time to test it right now. (Even though I'm pretty sure -25mV even on lower steps is still largely stable)
As for the set CPU test I tried them out on 1504Mhz: 150 and 595ms. I once pushed the tab to 1600Mhz but it ended up in an immediate freeze so I will skip on trying that again.
I don't have linpack but tried running GLBench 2.1 Egypt and the score was pretty embarrasing
Thanks for sharing. Since my post I have flashed aokp-34 galaxiansoup with v-3 of the Motley Kernal. Running 1400 on 216 no undervolting and am seeing a tiny increase in numbers. I'm still stumped on these linpack scores. This thing runs great. No complaints whatsoever. Anyone want to chime in on the best bench testing app or what the stock numbers on these 7310's are?
everyone will tell you that benchmark scores aren't very representative!
run the test 5 times and each time you will get a slightly different score.
i don't really care about benchmarking, as long as i feel that my tab runs smooth (which i think it does) im pretty happy. im normally at 1,4ghz and everything is smooth and stable!
Thanks for sharing. I couldn't agree more. My tab runs great at the same speed settings as yours. I just don't understand the numbers and how certain device's have like 100 times my mflops......I'm a numbers guy by nature, I like to see it on paper....but I am content with my device. Just always looking to make it cleaner and faster.....you know the addiction I'm sure.
Are you happy with this kernel? I found it stuttering and laggy...

Yes, I've not ran into any issues. Totally impressed and content with v3 motley. If there is a better kernel out there I'd love to hear about. I have yet to look, no need.
Been running a few custom profiles via Setcpu peaking @1.5GHz on B37 for a few weeks now. Other than a force close or two and an occasional browser freeze, which is normal with these roms, this thing is running pretty snappy. Gotta watch the temp though.

I sure hope that you've set up your profiles so that your tab overclocks to 1.5Ghz only occasionally, it's a thing that you HW can handle it, but will it on the long term?
Also, I regret that you can't overclock the bus frequency to get an overall performance boost (the GPU could really use it..) as on the Galaxy S
Yeah, I'm only pushing 1.5 on occasion, per profile. I normally run 1.4 all day everyday for the last 3 months with heavy use and no issues. Just gotta watch the temp. I've had mine to 113 degrees which kinda scared me.

How do you OC your device?

I am pretty new to OC so I cant figure out how to do it for 1.5 or 1.6 GHz.
Even when undervolting A1 kernel it is so unstable and cant pass antutu benchmark without crash and reset.
My best values are attached. Its A1 kernel, performance and cfq at 1.4ghz
I hope you will give me advice how to do better cpu benchmark values.
http://oi47.tinypic.com/2ia4ug7.jpg
You need a kernel that supports it. Look for one that is specific to your device.
God promised men that he'd put beautiful women in all corners of the world. Then he laughed and laughed and made the world round
My experience with undervolting is that the gain, battery wise, is nominal, hence I don't care UV.
I remember I got ~7300 in Antutu running CM10 @1500 with interactive governor. But benchmark
isn't everything, and I'm most happy with stock ICS with A1's 1.8.3c @1400 (interactive). I would
prefer running it @1500, but it tends to get a wee bit warm when doing this.
Of course I use kernel designed for my device.
In game overclocking for high performance are numbers important. Every 20pts in antutu benchmark (3d section) does matter in ingame fps (in my case shadowgun deadzone) and you can See it. So nobody has better score? :'(
I believe this is around the highest I got. No, you can't get too much higher. I am quite frustrated at this devices development - the xoom gets much better development and optimisation.... It is all about optimisation.
