Hello,
I read lots of articles about how the Tegra 3 only scores well in benchmarks because of its 4 cores, which are overkill in almost all real world scenarios. So I was interested to find out how the the Tegra 3 would do if you made it a Dual Core, like the S4.
I ran Antutu three times, running stock everything (except root), and the lowest I got was 7114.
I know it is not very reliable to use one benchmark, but in my opinion, neither is using quadrant which is made by Qualcomm.
I find it interesting to see that the Tegra 3 scores considerably more than the S4, even with the same number of cores.
What are your thoughts? What do you think caused this? What does it mean?

not too sure why it would still win hands down *shrugs*
How does the real world speed with 2 cores disabled though?
And does it seem to save any battery if you've had it going for a while.
I've had it set to two cores only for a few days. It makes NO difference to anything but benchmark scores (even antutu still shows 60 FPS in the graphics tests). Games like Dark Meadow THD run exactly the same as before.
I'm not too sure how it has affected the battery life as I installed a mod that lowers the auto brightness at the same time. All I can say is the combination of the two has dramatically increased the life of the battery
So the GPU is bottleneck (surprise)
Which GPU are you referring it?
maybe the benchmark tests are yet to be fully optimised for 4 cores?

My guess is the reason the Tegra 3 with 2 cores running scores lower than the Snapdragon S4 is because the Tegra 3 has 4 A9 cores, whereas the Snapdragon has 2 cores that are closer to the A15 architecture, which is a faster chip. A15 will be quicker than A9 if the same number of cores are being used in each chipset.
My One X scores around 11000 with four cores and, as you can see, 7114 with two cores. In just curious to know why with two cores it scores around 1000 more than the S4 version?

I think you misunderstood, the Tegra with two A9 scored greater than the Snapdragon. If you were correct, I would not be as surprised as I am and would not have started this thread.
Out of curiosity what are you using to lock the 2 cores?
Wouldn't mind trying it out myself
Open root explorer.
Go to sys/kernel/debug/tegra_hotplug
Open max_cpus in text editor, change 4 to 2 or 3 (Single core does not work).
Open it again to check it has saved properly and it will go back to 4 the next time you reboot the phone.
You know Tegra 3 has 5 cores instead of 4 cores in the A9 architecture right? So you basically did the benchmark with 3 cores instead of 2.

5th core is just a low clock speed / power to run idle tasks?
Doubt it would do much to a benchmark test.
Correct me if I'm wrong but the companion core can only be used on its own while the main processor is shut off. Even if it could 'assist' the main processor, it's only around 300mhz and would make very little difference to the score of a benchmark.

From what i know the 5th companion core is invisible to the system so 2 would be correct in the max_cpu edit.
I refer to my previous question which was why is the dual core tegra 3 doing BETTER than the dual core S4? Is it down to the GPU?
well that's revealing indeed, what's more interesting is how the included governors work
on-demand quad max 1400mhz conservative in jumping to max
interactive three cores only 1400mhz max jumps more often
performance three cores only locks at 1200mhz and jumps to 1400mhz on stress
glowball frame rate suffer badly when running less the 4 cores
you can see at default ondemand tegra3 is always juggling on 4 cores but rarely peaking to max clocks
While it indeed sucks as a useful tool, you should be aware that Quadrant is not a Qualcomm program...perhaps you're confusing it with the antiquated NeoCore benchmark. Vellamo is Qualcomm as well.
Sorry Vellano is Qualcomm not Quadrant. My mistake.

If you are referring to the s4 in the htc one s then id like to know where you got your information indicating that the tegra is still faster in dual core when in quad the s4 still out performs it. The s4 scores over 12000 compared to 11500 that the tegra does and well over 7000 that it does in dual core mode....
The older a9 however found in older phones such as the sensation is another story with that chip scoring in about 6500

I would overclock my HOX...in a block of ice. Or...well, in real life i dont want to overclock it because it would smoke out in my hand
Overheating is a big problem even without overclocking, imagine it running on 1,6ghz...

Can't really see why you would want to overclock the One X, the phone is blazing fast anyway, 4 cores at 1.5 is enough..
But like everybody else said, the phone would probably burn up..
I wouldnt overclock my device - at least not at the stage we reached now.
Why?
a) As long as there is no way to lower the voltage this might toast your device - its a unibody, keep that in mind!
b) 100 MHZ more would have literally no effect - its a 6 GHZ device, even if you boost it up to 6,4 - you wont notice, it will just drain your battery.
6 GHZ is WAY enough...this is smartphone...I mean...seriously...its got more power than my 4 years old 1K €uro notebook...

well first of all you can't just multiply the frequency by the number of cores. I'd much prefer an actual 6Ghz single core processor over 4x1.5Ghz because it won't have any compatibility and efficiency issues. Assuming they are of the same architecture and power usage of course.
Also the ARM low power SOCs probably don't have comparable number of commands per clock cycle as an x86 high performance CPU, even if it's 4 years old.

i agree.. when the multi-core CPUs first came out intel said doubling the core number would give as 47% boost in total performance (not x2 like apple says as they do not know it) lets assume that to be %50 to make the math a little bit easier..
so basically we can make the math here as; 4 cores at 1.2Ghz (when the all 4 active the clock is 1.2Ghz) gives us 1.2 x 3/2 x 3/2= 2.7 Ghz single core performance.. this value for SGS3 is; 1.4 x 3/2 x 3/2= 3.15Ghz
and here we can say dual core at (X) Ghz gives us (X) x 3/2=2.7 thus the (X) = 1.8 Ghz.. so, if you overclock any arm9 based Dual CPU to 1.8 Ghz you get the same performance "on paper".. if you want to catch up with SGS3 we need to OC it to 2.1 Ghz which is impossible at the moment i guess..
what makes the difference here is the lower loads or multiple loads on the CPU.. corecontrol users probably would have noticed; sometimes when the all 4 core are active the clock is only 480 or 640 Mhz (even 320 sometimes if i remember correctly) .. the same amount of load could be taken care of by a dual core at about 720 or 960Mhz.. but here the quad core system stays cooler with a little less energy consumed (or wasted) (as long as all the cores are in one uni-body structure, putting 2 or 4 single cores phsically together is not the case for our smartphones) this is how apple made sure about the smoothness of the ipad 2, new ipad and the iphone 4s.. they used lower clocked 2 power vr 543 GPUs.. when the load is little they can clock down to very low speeds and share the load..
and also you can always find an emtpy core waiting for new task when the others are busy..
so, long story for short; if we were dealing with a little amount but hard processes, having a single core at 2.7Ghz would be good since the quad core design would not cut one task into 4 pieces... as long as we were not thinking about the battery life and the heat.. but since we are dealing with lots of tasks which all could be handled by 1.2Ghz power having 4 cores is better for battery saving and having an empty core for a new task to run parallel with the other running tasks in the background..
It is OC out of the box I think Nvidia OC them for us and it's already pushing itself at the very edge of what is possible for it to do based on temperature, I seem to remember Hamdir saying something along those lines once upon a time...
Why bother to OC it's fast enough as it is.
---EDIT---
hamdir said:
only faux kernel betas allow OC
big warning OC is bad for the HOX given the thermal envelope
you are risking both you battery and processor if you OC
i know you are used to OC from other devices but those had headroom, it is not the case this time, T3 is operating at its max thermal capabilities on the HOX

the snapdragon 2 on the Arc had a lot of headroom
the chipset is rated @ 1.5ghz stable!
not the case with T3 its milking the very maximum of the 40nm process
in other words Nvidia is OCing its T3 out of box because their chips are designed to survive massive amount of heat (sadly it doesnt mean the battery or other components would survive)
it is already Overclocked lol
sometimes you have to listen to the "science" of it and surrender

I am a big fan of benchmarks but are there are really important
Please say what Kenel are you using.
No.

I would love to help you, but help yourself first: ask a better question

It really depends what you find important and what's useless. Its just for the certain few enthusiasts who like tweaking their devices and testing out different values to achieve a higher benchmark score and brag about it. I'm one of them although for the Note 2 I see little or no difference in performance when comparing between an over clocked and a stock setting.

Some people are disagree with overclock some not, benchmark are high only with overclock but if they are not important what are the reason?
I personally think that having a benchmark with a phones overclock settings turned on is the best way to see the true strength of a phone.
Some phones being overclocked do not even come close to other phones with out it being overclocked

So overclock or no overclock?
What you prefer?
When it comes to mobile phones, be it a ultra top end smartphone, absolutely not.
Swyped from my GT-N7100
for me, benchmark is only for fun and push it to the best performance of Note 2.
but for daily i still overclocked, 1.8GHz
it was stable and response very well..
Good way to compare devices. Although I do not overclock for my daily usage.
They are not for everyday thing but they tell their stories. For example I am a GPU comparison addict. I believe the GPUs are the first aging parts of the chipsets and if the GPU is not enough no matter what CPU or phone it is, it will fade away quickly. So when I am choosing a product I take one of the Nexus devices as a reference. For my Note 2, my referance was Nexus 7. Sİnce it will be getting at least 1.5 year support (the worst scenerio) Note will run any game for that time period.
So GLbenchmark comes in. Then it lets us to compare Nexus 4 and Note 2. What we can learn from it is, for example, Mali 400 is better for higher resolutions since 1080p and 720p results are same. Mali 400s quad core processors are so powerfull that they can not be effected by MSAAx4 or higher resolutions where Adreno 320 tenst to slow down however it has a bottle neck on the pixel processor side and it gets stuck on the Egypt 2.5 test no matter how much we OC it. So newer games will be a problem for Note 2 we can say. For the more older-coded games which are still close to the Egypt 2.1 side Adreno barely has %5-7 advantage over the Mali 400 so no problem for a long time.
Thanks for reply:good:
So, I was wondering if it is possible at all to overclock the Nexus 7 (2013). When I go to the app to overclock it (Yes, already rooted and installed busy box) I am unable to change max CPU's frequency higher than the default 1.5ghz. I also can't change the GPU's frequency over 400. Was wondering if there's like a limit to it or something. I was hoping I could overclock to 2ghz. Please help, thanks

Not to be mean or anything. But you really should not be overclocking your device at all when you don't even know what is required to over clock in the first place'. Let alone 2ghz.

Everybody has to start somewhere.
The kernel linked above should work fine. I would recommend backing up in TWRP/CWM before installing in case something goes wrong.
Why would you need to overclock this device? It already runs amazingly smooth with no lag whatsoever. What is it that you need the overclock for?

I am currently using stock rom with elementax kernel, cpu @1,72ghz and gpu @450mhz. When i tried 2ghz oc, everything worked fine, but it got really hot while gaming. So i´m asking me how dangerous it is to use such high oc values in daily life. How much could it decrease the lifespan of the components?

We can only guess. Keep it at 2ghz, and let us know how long from now before your CPU is baked, then we'll all know for future reference.

Actually it is an underclocked snapdragon 600, but i didn't know that this cpu supports a clock speed until 1.9ghz (thought 1.7ghz would be standard clock). So i think up to 2ghz there shouldn't be any problems and it's okay for everyday use. I've also heard of some rumors that our nexus 7 2013 contains a "second choice" snapdragon 600 chipset, which didn't fullfill the predetermined requirements and that's why it was rebranded as an s4 pro... but this is really unimportant and just speculation.

omg you certainly shouldn't overclock it because the SOC architecture is designed to run at optimal clock speeds... by overclocking it, you might shorten the lifespan of your device and you might even damage it permanently as well

By default, yes. However I used TricksterMod to upgrade it to a Snapdragon 800. The device is absolutely flying now :good:
You can't "upgrate" S600 to and S800 , the S800 is a newer cheap - uses a newer Krait 400 cores which are more optimized and power efficient and on top of that it has a newer more powerful gpu - adreno 330 vs 320 on the S600/S4 Pro , also the S800 has a newer DSP embedded so it can decode 4K content.
clock to clock the S800 would be faster, and as the S600 wasn't design to run at 2.26GHz (highest bin of the S600 is 1.9GHz on the S4 , then the 1.7GHz on the HTC One, and finaly there is the Nexus 7 Which uses underclocked S600 with different branding) the S800 would be more power efficient .
