low linpack scores:

I would like to understand why my own device, as well as many review samples, seem to score much lower in linpack that they're supposed to.

provided that for such a short bench it cannot be a throttling issue, I can't seem to go over 200-something multithreaded and 70-ish singlethreaded, while some people are reporting scores that are many times more than mine, with someone claiming over 900 (0? :P) in this very thread.

Antutu scores well over 20k, so it can't be a misconfiguration issue, and I'm using the performance governor while running the tests.

a quick search didn't lead me to anything so I wonder if anyone knows what's up with that.
[Nexus 4 General] trillo69:
Fast or faster means nothing while benchmarking. What matter are your rom mostly, and your kernel/oc. Of course you may need to tweak voltages because it may not be able to run antutu properly at high oc if voltages are too high or too low. Just see simms22 benchmark with a nominal chip.

And of course temperature, try to have your battery temperature below 35°C before start the benchmark. Otherwise it might throttle.
[Nexus 4 General] Ace42:
Since all chips are not created equally, is it possible that some chips have higher computational power than other ones? If voltage tolerance can vary then, isn't it possible for performance?
[Nexus 4 General] simms22:
yes.

just not from what its binned. the phones binning just shows what voltage table is best for that device, not its potential performance abilities.
[Nexus 4 General] SetiroN:
Absolutely not. Logically every CPU is identical and will perform precisely as any other one within a 2% margin because of extremely slight differences in memory errors. The performance difference between identical silicon in separate SKUs (I.e. Intel's core series) derives from different frequencies and enabled/disabled features and/or cache memory.

Every core i7 3770 performs exactly like another (unless you start overclocking), although it will be faster than the physically identical core i5 because of its larger amount of enable cache and hyper threading technology.

In the same way, every Snapdragon 600 performs identically and the only differences you see are due to software.
[Nexus 4 General] simms22:
not true, no such thing as exactly the same, unless we live in a perfect world(and we dont). there are other variables that change things.. when/where built, who built it, the tiny parts that were used to build it at the time it was built, etc. in the end, these things have an affect on performance.
[Nexus 4 General] simms22:
im averaging between 350-360 in linpack
[Nexus 4 General] Connor Baker:
I'm deferent definitely missing something then. I just got a 72 on a multi threaded linpack.

[Nexus 4 General] Ace42:
You're using Trinity kernel? On faux I get 170 linpack [MENTION=1247388]1.6[/MENTION]ghz and performance gov.
[Nexus 4 General] SetiroN:
Sorry to be blunt but you have no idea of what you're talking about.

The differences that you refer to have to remain within certain limits, above which ; the CPU logic has to precisely follow the guidelines, if it doesn't the part is considered defective and thrown away, or downgraded as a lower end component (if such part exists, for example core i7->pentium/celeron) by disabling the defective parts, so long as the remaining of the chip complies with such an eventual different SKU guidelines. There is a margin of error warranted from lowering the operating frequency or increasing the voltage, but the logic needs electrically work in the exact same way, otherwise it just doesn't. As I said before, the only possible +-2% differences can be attributed to slightly different error rates from the integrated caches and memory controllers that can be tolerated with error correction.

If you think your linpack result is proof of what you say, you're wrong, such large differences are obviously due to major software differences (like JIT not working properly, or Dalvik not working properly).

Need actual proof? Run linpack in native mode, i.e. without going through Dalvik like with stability test, and my score will magically match yours:
[Nexus 4 General] simms22:
my linpack score has nothing to do with this, it was for the other post.

and again, you are right, in a perfect world. the manufacturers do work this way. but the slight variations that do happen, do impact the devices performance, up or down.
[Nexus 4 General] SetiroN:
Let's just say that we agree to disagree.

What ROM are you using? Would you mind posting your build.prop?
[Nexus 4 General] simms22:
ok, i agree to disagree :)

im using rasbean jelly(the latest build), with trinity kernel tf133. heres my build.prop, the only things i changed was flash something for my lte connection(thats where the molesarecoming ro.build.display comes from, as well as the paranoid android stuff also) and added the last for lines to help with my hspa+ connection.
[Nexus 4 General] SetiroN:
So after trying out a few build.prop tweaks without reaching the desired result I went ahead to download rasbeanjelly along with the latest trinity kernel just to make a point...

downloaded linpack, forced 4 cores online and 18xxMHz while disabling thermal throttling and started testing: over 100Mflops single threaded, nice, let's run a few multithreaded ones:

300, 330.. black screen; weird sound out of the speaker, red led flashing on and off and windows continously repeating the "new unknown device" 'tuh-duh' sound. I instantly removed the usb cable, the phone was fiery hot.

After waiting a bit it wouldn't boot; I waited until it was cold, still nothing. No signs of life, inserting the usb cable would once again result in a flashing red led and windows finding a new unknown device.

I was pretty sure I fried something, which came as a shock as I thoght it wouldn't be possible at the relatively low voltage of 1225 at which trinity defaults.

Luckily, the bootloader key combination worked and I managed to boot normally from there: apparently the battery went crazy and reported 0%, because of the sudden spike in power consumption.

****ing hell. This is the last time I repeatedly tap the multh-threaded bench button.

---------- Post added at 12:07 AM ---------- Previous post was at 12:01 AM ----------

Anyway the conclusion is: although they share the same base, standard PA must have some optimisations missing that rasbeanjelly definitely has, as even at 1512MHz there's a wide discrepancy in the results: the latter consistently scores over 100MFLOPS single threaded.

What this translates into in real world performance remains to be seen, but the raw processing power difference is substantial.
[Nexus 4 General] simms22:
ahh, you experienced rlod(red light of death). and you fixed it the right way instead of freaking out :D my phone doesnt get rlod, instead it goes to 1%(instead of 0%). but its very common for many phones to get rlod(seems as newer models get it less often). btw, trinity has all four cores on by default already.
[Nexus 4 General] Ace42:
Rasbean has optimizations not related to the build prop, those can be found only in ROM source.

[Nexus 4 General] meangreenie:
asuming it's the gs3 snapdragon version (though i seem to remember both types had similar performance)........

cpu wise the dual core kraits put out about 2/3rds of the score in benchmarks such as antutu/quadrant against quad core kraits (s4 pro)

gpu wise.. the adreno 320's in the quad core kraits seem to be @ twice as fast as the adreno220's found in the dual core krait chipsets (3dmark for example)

..it's quite a rough estimate though, as different benchmarks will show varying differences.
[Nexus 4 General] krjadejesus:
Benhmarks do not totally reflect the actual performance of the device.
[Nexus 4 General] simms22:
thats right, they reflect random numbers that the device generates just for the heck of it, in no meaniful or useful order. anyways, if you noticed, this thread is for fun. theres no one performing complex scientific tests here. or do benchmarks not reflect actual fun/entertainment value that these people are having/had either?

Is there a ROM that's faster than rasbean????, I've certainly not found one yet : (
[Nexus 4 General] Fatherboard:
Some fine numbers here - My N4 is running bone stock, and it can't pass 4900~ in Quadrant (with a lot of hiccups & frame drops, looks like it's not optimized for JB 4.2.2, nor N4 in general), and 15,000~ in AnTuTu.

My friend's stock HTC ONE X seems to handle this much much better, and scores 7000~ in Quadrant. I presume I'll have to replace my ROM/Kernel in order to match or bypass his device.
[Nexus 4 General] simms22:
yup, change the rom/kernel to pass your buddy. the stock rom needs to be seriously optimized to do much better.

The last time quadrant was updated was in may 2012 for ICS. Antutu is far more accurate.

I get that. However, how would you explain the way higher Optimus G benchmarks then? And yes, we will have to wait and see, just trying to point that out,:good:
[Nexus 4 General] Harry GT-S5830:
Either hardware throttling

Or the 'development' software is a piece of crap running like an 2.6.8 Kernel

Also, has this got the Architectural Enhancements that we see in Krait cores? as this is pretty much Krait V2
[Nexus 4 General] jader13254:
Optimus G has been internal developed month ago, and is fine optimized and tested, as well as the fine but old kernel. Nexus 4 is expspected to reach more than Optimus G, since

1. 4.2 is faster, due internal optimisations in system, as always when new android arrives ^^

2. The new linux kernel which is expspected to be faster and stabler due its based on new sources and not froyo as my jb arc s is still based on ;)

@OP

Please add that this are pre-release phones, and update your thread after real benchmarks (which still aren't representive, because important is how the phone feels in starting apps and running games.

Benchmark can absolutely say NOTHING. I could modify Quadrant by an easy hack, and it would show complete C-R-A-P. What would you say if you just-looking-for-benchmark powered guys (some though) get trolled by google with an hack in system which always shows 100.000.000 Points in Quadrant ^^ OMG Nice ;)

Real important for me is that we get fast updates and no fu#@@#* Sony Facebook, Sony Live...

[Nexus 4 General] NODO-GT:
I'm really disappointed. I was sure it would perform much better than optimus g...

Yes I do care about benchmark scores. One can say that single benchmark is not showing real power of the phone, but when we are looking at lots of different benchmarks, and in all of them we have poor performance, this is really showing that something is not right.

Leave alone benchmarks, WTF is 22fps video recording @ 9mbps??? Video looks like ****.... I hope I'll manage to mod camera app as I did for sensation...

I'll defiantly postpone purchase of this phone. However I still have hope in google to update software and in xda community to tweak hell out of this device.

I would rather get optimus g, but sadly I cant afford it for now.

[Nexus 4 General] munkustrap:
I‘m pretty sure too without knowing anybody in google.:D From all the phones I've used, never had all those annoying "tiny" problems with nexus aosp roms as others had. Never figured out why and how those manufacturers managed to develop those "add-on" craps to make our lives harder.
[Nexus 4 General] jader13254:
If you had a panasonic phone once you know it ;) FUU
[Nexus 4 General] albundy2010:
It better be a software issue and not any throttling what so ever.

1. If the device has to throttle itself to run not intensive benchmarks like quadrant and antutu that is problem. I highly doubt that is the case. The same soc is in the optimus and runs fine. There should be no reason why it gets so hot it has to throttle itself running a benchmark that shouldn't even full stress the CPU in the first place.

2. Well I forgot really. But this thing just can't actually be getting thermally throttled running these test with stock speeds/volts etc. For that to happen on a hardware level I think lg would have had to forget the thermal paste on the heatsink.
[Nexus 4 General] chrisjcks:
Its defiantly a software issue of some kind, just check the speed of this thing.

If you look at early scores for N4 vs iPhone 5, the nexus shows its worth with geekbench
[Nexus 4 General] hamdir:
Nevermind the CPU guys, its clearly not yet optimized for the proper quad usage

the scores are more inline with dual krait instead of core

the worrying bit however is the GPU, the scores are seriously much less then expected

we really have to ask if Qualcomm underclocked the GPU for thermal or battery concerns

anyone managed to get similar Egypt scores to the Optimus G on the N4?

if anyone has access to the N4 please test specifically the Egypt tests, don't run the full set of tests like anand did

they said it themselves the entire test suite was causing overheat

just the Egypt HD tests on a cool and fully charged Nexus 4 should let us know if the Adreno 320 is underclocked or if it was simply throttling
[Nexus 4 General] jader13254:
I more think it was throttling because its not yet really optimised. Underclocking the GPU isn't really.. ..usefull for a finall version ;)

Wait for the Release & run a benchmark, lets see what happens, btw geekbench looks promising since its 3 times iPod 5, and iPod 5 is kinda fast ;) 2,5x iPod 4 and iPod 4 is faster than my currenct arc S means... Nexus 4 is 7.5 times faster than arc S (nice)

17k is @ the max you can get with stock rom at stock speeds whatever the kernel. the stock rom for N4 doesn't have the krait enhancements built in.

For consistent scores in antutu run cpu in performance governor mode (or any similar method) and also when it's cool.
[Nexus 4 General] simms22:
performance governor sucks :p

id recommend ondemand or interactive set at the same max cpu speed/min cpu speed(1512mhz high/1512mhz low for example)

[Nexus 4 General] simms22:
cool down the phone first, try a different governor/scheduler, or you can try changing voltage for that cpu speed. raise the voltage little bit at a time, until 1.7 works for you. if not, try lowering it a little at a time. if still it doesnt work, then your phone just cant handle it.

only thing i did was set governor on "performance" and put the phone in front of a fan. if the cpu gets hot, thermal throttling will go on and you will "only" get 15k~18k points.

also running benchmarks one after another will decrease score too, because there's not enough time for the phone to cool down even with a fan on it, and the nexus 4 has not very good thermal dissipation because glass likes to hold heat instead of getting rid of it.

I experience antutu closes automatically (at the very first step of the benchmark) when i try to benchmark my device at 1.7 or 1.8.

I'm using 1300mV on that frequency too as I thought it required more power. but antutu still forced closed. I know not all devices cant handle 1836MHz but i would of thought i would be able to run antutu at 1.7.

any suggestions guys?

EDIT: antutu closes when benching higher that 1562MHz
[Nexus 4 General] simms22:
that voltage seem very high, my phone freezes instantly at 1300mV. 1275mV is perfect for my phone at 1836mhz, 1250mV runs too. but for others 1200-1225mV is good for 1836mhz. also, my phone wont pass the first stage of antutu either at 1836mhz, unless i start the benchmark when my phone/cpu is 5C or less. if i start at 6C, it will kick me out. so, cool down your device first :)

Antutu & Quadrant Benchmarks - sigh.

When will they ever end?

We are seeing double priced Google editions of the S4 and the ONE which run no faster and no smoother (and actually have lag in the app launcher)

But to some people, a stock N4 at 18k Antutu compared to 24k or whatever it is, is still the holy grail of performance testing.

I can flash CM and get 23+k and still role back to stock as it just seems snappier - or at the very least, the same.

Bout time people gave up these methods of testing!

I can understand running 3dmark / GL as your actually seeing a proper intensive test & result that relates to something specific - but apps such as Antutu and Quadrant that are supposed to test-all are extremely inaccurate and in no way show how fast or smooth different devices actually are.

For me, performance is what I want - not a fantastic camera or extra features and performance benchmarks are not showing what I'm seeing with my own eyes.
