I figured I would run quadrant stand and see what I got and I got some interesting results. I got a score of 1830 which is a little bit less then what people have gotten on my phone the Samsung Galaxy Prevail which is a lowend single core 800 MHz Qualcomm MSM7627-3 plus the phone only has 384megs of ram. On top of that quarant says the device only has 1 core so Im not sure whats going on with that
I really don't care for quadrant -- at all. It provides far too divergent results on different devices of the same model/SW, it often does not use all available resources to test a device, and I find its results far too inconsistent to be worth regarding as anything other than a random grouping of numbers.
Im just wondering what other apps see the cpu as 1 core and not the dualcore it really is like quadrant does.
This section is not for discussions like this. This is more suited to the general section.

The Nook Tablet usually turns off the second core in order to conserve battery power. I don't know what the conditions are wherein it will spin up the other core.
hmm could be why some apps are a bit slower then others. and why a lowend smartphone is getting better quadrant scores then this dualcore of a monster

Mine got 2140. And a phone with a 800 mhz processor cant reach that unless it is rooted and overclocked. Only on CPU i got around 1500 points. So that means with custom rom the graphics can be improved and with overclock i think it will be able to reach at least around 3500. And quadrant its not so accurate either.
If you check this thread you will see a couple of people that are running CM7 have gotten 1900-2100 scores

Hello XDA,
I was just wondering if anyone else have encountered the same issue (not sure if it is an issue).
When I run Quadrant Benchmark, there is only 8 CPU showing. I have googled and have seen a few videos shows 12 CPU during a Quadrant Benchmark.
I have attached screenshots of the information Quadrant Benchmark shows.
Also Quadrant seems to only show 1 Core in System Information.
Not sure that the device being a refurb would have anything to do with it. But I just want to make sure that I am getting the most out of my phone, and may be also possibly increases by benchmark scores to the 4000-5000 range as even with just 8 CPU I am averaging between 3000-4000 benchmark points.
Any clarification and assistance would be greatly appreciated.
Thank you in advance!!!
I think you're quite confused . The "8 CPUs" are the number of tests it runs to test the CPU portion. Could be as simple as they previously used 12 tests but have now managed to test the same things with 8 tests. You phone doesn't have 8 CPUs
Quadrant often only displays 1 core because the other "sleeps" when not needed. Once the demand for more power is there it'll wake the second core.
If you want higher scores you can overclock, change governor, etc. but really benchmark scores are meaningless
Quadrant was updated several months ago and the number of CPU tests was reduced to 8 from 12. See this post (its a june 2010 post) http://www.aurorasoftworks.com/products

Thank you
Hello All, Thank you to the both of you for the clarification and guidance. Much appreciated!!!
Have a great day/night.

You have to wait for one of the mod's to close it. Maybe they'll close it, now that you've requested it. Or maybe it'll just stay open and get buried, which is fine too.
Pm a mod and request it to be closed.

Hi,
I want to see the power of Snapdragon 800 in terms of chess engine copmutation - droidfish chess app (stockfish 4). Usually on my Note 2 i get ~800knps, galaxy s4 got ~1000knps and i wonder if this new powerful phone as all say it will pass 2000knps mark...
All you need to do is to install droidfish (free) from google play store. Configure it to use 4 cores ("threads" section) - then pick some random chess positions and press 'M' and "Analyze" - that runs the stockfish chess engine to evaluate your position - look at the bottom of the screen - the eval line there contains the knps number (kilo nodes per second) - pls publish it. The higher the better...-
Thanks
From the new game position I'm getting nps: 171k
Verizon LG G2
Hope this helps

171k is too low and does not make sense...
Please make sure you configured 4 cores in "threads" section. Also - move some pieces to let it work...

Very weird...Can't be my Note 2 is stronger in that.
Can you try this position - let it run 10 seconds on it. Maybe it is somehow limited so you need to enlarge hash table size..?
Clock starts high then throttles down to 1200 or so, knps at 411 now.

Very Very low. For my position i attached it is steady @ 700knps. IF that is true it is very very bad performance.

Look at this thread - someone complained similar issue on S4 4 cores version (Snapdragon throttling issue??)
http://forum.xda-developers.com/showthread.php?t=2264209
Please check when using 4 cores - what's the actual cpus speed....!?

~650knps (again, galaxy note 2, 4 cores, hash table size does not change anything)

As I said before, it seems to throttle CPU speed down to 1200 after a little bit.

So 4 cores can't run at 2.26GHz all together....What a shame..
BTW, which tool do you use to see all cpus speed?
Can you check if setting threads to 1 - if it runs at 2.26GHz? Since i get also 171k (starting game position) on 1 thread on weaker cpu....
UPDATE: Just checked with System Monitor App - no cpu speed down on note 2 even regardless number of cores used (1 core runs @ 1.6GHz, 4 cores runs at 1.6GHz (each) either...)
Looks to me like a bug in Snapdragon 600/800 in this kind of load. I never saw LG claim they can't run all 4 cores at 2.26GHz each.
I am using System Panel. When I set threads to 1 it oscillates between 1200 and 2200.
I have seen up to 609k since rebooting.
My Nexus 7 (2012) is a bit slower.

I am contacted also to Droidfish programmer to check this weird behavior - maybe this is related somehow to the SW behavior but i doubt it...
Yes I meant 609 on 4 cores.

This is screenshot of cpus clock speed on my note 2 which look good as expected (constatly set to max clock rate on each core)
So if we gather all finding so far - the version of galaxy S4 that uses octa-core (NOT snapdragon) also performed WELL on 4 A14 cores - result was ~900-1000knps which is good and higher than note 2 as ecpected. Snapdragon 800 should have beaten both...But it performs poorly - and this is real life scenario for chess players...
It all looks like snapdragon issue or droidfish is not optimized to run on snapdragon - don't know. Yesterday I sent emails to LG & Droidfish developer to comment on that since something is wrong here. No response yet.
It's probably a combo of the gov and scheduler. Difference between the 2. From Samsung. This phone doesn't need to ramp up that high to perform better. And gpu takes a lot off it. Your comparing two completely separate arch and govs

Hi guys, i will buy this tablet because i loved it but, i have a doubt, i have been searching in internet and i read that it has 8 cores (4 to 1.5GHZ and 4 to 2.0GHZ) so, it will work with all the cores? i mean, if for example, it is not in use will work with 4 cores to 1.5GHZ or it will work with all 8 cores, if 4 cores to 1.5GHZ are full, it continues with the rest of them? (the other 4 cores to 2.0GHZ) i dont know if you understand hahahaha
Example:
Aplication: Facebook
Cores working: 4 @ 1.5GHZ
Aplication: Youtube
Cores working: 4 @ 2.0GHZ
or
Aplication: Benchmark
Cores working: 6 (4 @ 1.5GHZ and 2 @ 2.0GHZ)
I hope you can understand this weird question, Greetings
I've been asking myself the same question! I've come to the thought that the tablet will use as much resources as it needs at the moment for its current operation. For example you are just browsing the web: reading some stuff. It will use the 4 x 1.5 Ghz, if you start a big 3D game it will use its full capacity. Sorry if I'm not giving you the most expert explanation. Anyway, have a good one!
Based on Qualcomm specs, 810 is 8 cores.

I'm only going on what I remember reading, and none too recently...
Also, I haven't read much info on the Qualcomm 810 specifically, but I believe it is based on ARM's 'big.LITTLE' architecture, as are Samsung's Exynos 5 'Octa-core' processors.
I believe the Exynos SoC's can make use of (at most) only 4 cores at a time, but in any combination. However, since the 810 is significantly different than previous 'big'LITTLE' SoC's (namely in being 64-bit), I guess it's possible to have 5+ active simultaneously.
Running on all 8 cores makes my wonder about heat restrictions, though. And considering that the slower cores are mainly useful in reducing power consumption, I'm not sure how much more additional processing power they might provide.
All this in a tablet with a 1600p IPS screen (power/processor hungry), quite thin (less mass available for heat dissipation), and a 6000mah battery (a bit small, perhaps? even if Sony is very good at battery usage.) Off Topic: Anyone remember Sony's audio-cassette Walkman that ran (and ran) on only one 'AA' battery?. Regardless, I want this tablet!
Um...sorry if this post was not too useful, actually.

This should give you a good insight into how 8/multi cores work on Android and how it's benificial: http://www.androidauthority.com/fact-or-fiction-android-apps-only-use-one-cpu-core-610352/
I've read that the 16Gb Redmi Note 2 has the GPU running at only 550Mhz while the Redmi Note 2 Prime has its GPU running at 700Mhz. Is this correct?
If it is, it's a much more significant difference than the 0.2Ghz in CPU clock.
I posted the exact differences somewhere (here).. you can look for it.
