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.
Sent from my Incredible 2 using XDA
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

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

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)

I suggest you flash faux's kernel.
It can oc to 1.6GHZ for most user~
and it support s2W!
I expect many users will be aware of this information, but just in case you aren't.
Anyone overclocking should be aware that this will usually lead to higher power consumption which leads to more heat produced and lower battery life.
Especially if it is necessary to overvolt to acheive higher clock frequencies with stability.
Power consumption is proportional to Voltage squared, so small increases in core coltage can result in larger increases in power consumption than mught be thought.
Needless to say this can have negative impacts on battery discharge time and overall life (due to higher temperatures).
Plus there may be some throttling back of frequency if high temperatures are reached. Also possible that frequency may be reduced to 1Ghz maximum when battery voltage is low (i.e when discharged)
Hope this is helpful (first post here)

CPU throttle starts at 85c with thermal TJ-max of 99c.
also there is many debates about this, higher speed need more power which drains battery, but that said it means work gets faster meaning it can idle faster saving power, same the other side slower speeds save power but take longer to get work done using more power.

Go to Faux123 and read the opening post
http://forum.xda-developers.com/showthread.php?t=1647993
it will teach you about Tegra 3 variants.
Flash Faux123 latest kernel to know what variant you have.
You can have 1.5ghz quadcore minimum, except if you have the poor variant0 of the Tegra 3, and 1.6ghz quadcore max if you have variant 3
So the overclocking you can achieve depends on your Tegra 3 variant, whatever the kernel, don't trust the figures in kernel threads titles, they just give the max if you have variant 3. And the majority of people have variant 1 so limited to 1.5ghz quadcore and there's nothing to do about it, no future kernel can change the way your CPU was manufactured.
Just, SetCPU can display 1.6ghz or more, but if you have variant 0 or 1 it will never use it (CPUspy will say 1550 and 1600 are unused frequencies)
Variant 1 can go upt to 1550mhz but not for quadcore, so who cares....! Same for kernels claiming up to 1.7ghz, it's in single/dual core, so once more, who cares?
What is important is what max speed you can achieve in quadcore, nothing else, and the limits are clearly defined by your Tegra3 variant
"all chips are not created equal" was a silly bull**** invented more than one year ago as an easy answer to noobs claiming they couldn't overclock their dual core at their max. Now, on the One-X and because of Nvidia unstable quality"all chips are not created equal" is sadly the truth.
PS: wrong=> to say that overclocking means more voltage, undervolting a custom kernel a little can surprisingly reduce heat when you push your CPU to its max,I can have both 1500mhz quadcore and less voltage than stock, as well as less heat (I was surprised, really, on the Sensation I had always found undervolting kinda useless)
PPS: true=> thermal throttle will always come pretty soon and reduce your max speed......

Your argument makes sense, but unless the governor is very efficient at controlling the CPU speed very quickly, in most cases your argument doesn’t hold true. For example when playing a game or running a CPU intensive application (where overclocking has any use) the processor works at full speed for the duration of the application.
EDIT: Frankly I don’t see any point in overclocking a phone like One X. I don’t play many games, but the few games I have played ran very smoothly. And if people are overclocking because of the (barely noticeable) laggy UI then overclocking is not a real fix anyway. Installing a custom ROM (perhaps JB), a different launcher, tweaking background apps/services are some of the more sensible and effective things to do instead.
No disrespect to the devs who are working on overclocking, but IMO HTC and nVidia must have spent a considerable amount of time and effort designing the CPU and deciding the optimal operational parameters to maximize performance while minimizing battery drain. Therefore anything out of those parameters (in theory at least) should impact either stability, or battery life. Perhaps the values HTC has decided are not the maximum possible values , because I assume they would have designed the phone to handle few exceptional conditions (i.e: extremely hot weathers). But I think over clocking would probably cause more problems in the long run than whatever the little gains you experience in short term. Just my 2c.

Qualcomms hotplugging in the kernel uses 2 cores for most tasks. Its only when it requires a lot of processing power it kicks in all 4 cores. This saves battery and creates less heat.
It's part of the new smart philosophy. Uses cores depending on use to save battery.
I kind of like the LG Optimus g feature of ECO mode. Switching between 2 or 4 cores anytime.
Thanks, I thought that, but wasn't sure.
According to HTC website, the SnapDragon 810 in the M9 is supposed to be clocked at 4x 2GHz cores, 4x 1.5GHz cores.
Both CPU Stats and CPU-Z report a max speed of 1.5GHz...
Are we being sold underclocked devices?
I know about the supposed "thermal issues" but to advertise a device at 2GHz but ship it at 1.5Ghz is a bit naughty.
Can anyone confirm their device is running at 2GHz?

Indeed, that's why I want to know if others have devices running at 2GHz and this is just an error in these apps. But, if they are clocking at 1.5, they shouldn't be advertising it as being 2 on their website and everywhere else.

Good spot, installed Antutu and it recognises max speed of 1.9584GHz so it does look like it's not underclocked.
Running benchmark now - done, and it didn't get hot
" The new phone has a processor that’s theoretically faster, a higher-resolution camera, and other things that should make the new phone an upgrade from last year’s model. But early reviews suggest the new camera doesn’t take stellar photos, the battery life isn’t great, and in order to keep the CPU from overheating HTC recently pushed out a software update that reduces the clock speed… which means the new phone’s probably not much faster than last year’s model.

Mine is a tad slow playing Football Manager Handheld 2015 which is much quicker on the Note 4 and M8. I think this may well be due to tinkering on HTC's part as during the game the phone is quite cool, but doing other tasks it gets quite hot.

Understand that both of those other phones have 32 bit processor's, most apps are probably not optimized for 64bit. So that may be why that app is slower.
And yes you can be quite sure this phone has a thermal throttle, but don't be mistaken. So does every other phone out there.

@LeeDroid which cluster is 2ghz the A57 or A53?

That's the A57 mate.
None of the CPU stats Apps on the market offer support For octacore as yet, they will see that we have 8 cores but won't be looking at them directly

in power saver mode the 1.5ghz cluster minimum reduces from 600mhz to 300mhz and the 2ghz cluster gets disabled, so according to this information the A57 cluster gets disabled completely in powersaver! the slow down is very evident in the camera
Nomal mode:
633mhz to 1958mhz
first 4 cores A53 cluster hover around it's maximum 1555mhz (capped)
second 4 cores A57 cluster around 700mhz idle, it goes all the way up to 1958mhz
CPU powersaver:
300mhz to 1552mhz
first 4 cores cluster A53 hover around it's maximum 1555mhz (capped)
second 4 cores A57 cluster disabled
GPU Adreno 430 speed between 190mhz and 600mhz, not affected by CPU powersaver, drivers [email protected] ([email protected])
when the device is warm (downloading non stop over wifi) battery temp around 39c, a little less load and the battery temp is around 36c

Yeh that would make sense mate, dropping min freq on the a57 would likely cause freezing, power save bumps us down to a good old 1.5GHz QuadCore, camera is Damn resource hungry so the imminent slow down would also make sense.

how does 1.5ghz quad A53 compare to a 1.1ghz quad Krait400? if we are comparing powersavers M8 vs M9
also some correction:

All that was tweaked is the interactive governor, it was too aggressive, none of the core clock speeds have been reduced

that's not true, they also added thermal throttle to the GPU, all the way from 600mhz to 300mhz which also brings it down to M8 land (once throttled)
Ah indeed!
Hadn't considered the throttling, I don't tend to use power save a great deal however happy to do some comparisons when I have time
