Is it possible to have a partially working processor?

It has come to my attention through benchmarks that my CPU is not performing anywhere near where it should be. It also has a -1C reading on Core 2 (technically the third core) in Synapse that occasionally flickers a temperature that is MUCH lower than the rest of the chip (like if the rest of the chip says 70, it will say 40 and it idles at 27C while the other cores don't go below 33C).
My AnTuTu is 62k and my AnTuTu beta is only 76k. In the AnTuTu beta, even the One M9 is destroying my chip (I only beat it on RAM score, Multi-Core, and 3D) - the UX scores are all about 25% under the throttled Snapdragon 810 and in the beta, the Note 5 should score almost 84k. The only benchmark that my phone is beating it on is the 3D benchmark (14602 to 13929).
If my CPU IS damaged... How on earth would I even go about getting T-Mobile to understand what I'm talking about? I mean the phone performs admirably anyway but if this isn't the performance I should be getting, I don't want to have a defective phone...

Is your phone working properly when doing phone things? Is it modified?
What software version are you on? Kernel?
We need all that.
By the way......scores don't really mean anything as It's a cellphone, not a gaming rig but understandable people want to test performance. Do you use your device mostly fire gaming? If so do you get any lagging dieing play now compared to before?

I just got a note 5 from t-mobile today and my antutu benchmark is 41022. Under the Note 4. Im thinking I should take it back. And I did a system restore.
Gonna be fun explaining this at the store.

1.6 GHz max and only using 6 cores...

Hey guys,
i just got my LG G Flex 2 here in germany for christmas and im very happy with it
But there is 1 but important (for me) problem.
It only uses 6 out of 8 cores and the max clock is ONLY 1.6 GHz...
in Antutu im even behind the LG G4 with that "SLOWER HEXACORE" ...
Can someone help me and tell me how to get rid of those 2 problems and get 2 GHz for the Big Cores?
Also, how to easily root my german H955 with Android 5.1.1 ?
Thanks for answers and help
Edit: I got "V15-c-EUR-XX"
Edit2: GPU runs 600 MHz max instead of 650 MHz ...what did they do with my phone
Edit3: I already checked temps, before you ask. 35-40°C max.... i dont think it should throttle at that low temperature.

Okay, now, on the next day it shows up to 1950 MHz for those 4 cores.
Seems to be a temperature problem at only 35 °C ...
Whats the easiest method for rooting the flex 2 (V15-c-EUR-XX) ?

I am not sure if for this phone is the same, but sometimes if u have low battery the kernel switch some core off.

Its normal,sometimes it underclocks the CPU and not always is phone running on 8 cores.... And what about GPU? Well,i have same distribution (DEU) and max is 600 MHz,but currently i have it on 305 MHz. Personally,i never saw higher clock of the GPU,and i own this device for almost month.
Edit: the GPU underclock may be caused by Energy saving mode. However,this has no impact on CPU,CPU-Z shows 1,96 GHz even in Energy saving mode. I had same problems too,CPU-Z showed 1,56 GHz maximum,after restart 1,96 GHz max.

Thanks for the responses. One last question. Why do i get only 60k in Antutu where others get 75k+ without fridge or such?

Well. about an hour ago i ran Antutu test and got 68 000 points. However,it was much worse before (first antutu test had 48 000 points and i was shocked). There are many things that can influence the score. For example-power saving mode,current RAM status (how many apps you got in background),battery percentage and temperature. Maybe best time for test is cold start,when you jump right to Antutu after start (of course not right after,phone needs some time),because you have lowest temperature,highest free RAM and no background apps. If i did such test, i would score more points i think. And last thing-the performance drops significantly when you do many tests in in a row (i mean 1st test and then in about 10 secs other one)

Yeah my performance also seems to increase over time. Weird.
And yes this soc throttles easily. But it doesnt get as hot as my nexus 5 was sometimes with benchmarks and is still faster when throttled. Would not call this processor a fail at all.
Still hoping that the SD820 will be better in thermals though. But this chip is still more than what I need.

How is the battery life when it runs on lower clock speed?
Can someone please use the phone with underclocked cpu (1.6 or 1.8GHz) for some days and post the experience on battery, temperature and phone responsiveness? Thanks.

Battery life is not improved when the phone runs in 1.6 GHz mode. I usually get about 3 h screen on time. The phone heats up a lot under load. I never saw my phone using the full potential with this Snapdragon 810 CPU. It always runs at 1.6 GHz and that seems to be fixed by the ROM on mine.

why is this processor so battery hungry?

I previosly owned a Moto X Play and it didnt consumed more than 3% and at redmi pro is minimum 12% . Data and wifi always enabled

There's definitely something with the thermal management of the processor, as evidenced by the difference in Antutu scores hot vs cold where I see 30% difference, low 70000 versus > 100000 - and by "hot" I mean after 10 minutes of browsing, not playing intense games.
That said, compared to a similar spec phone like Elephone S8 the Redmi Pro looks pretty good. With a similar battery rating and X25 if I leave both idle the Redmi Pro still has 35% charge when the Elephone S8 hits zero. Yes the Elephone has a larger screen, but by idle I mean mostly just sitting there with the screen off.
Can't comment on the Moto X Play but if the Snapdragon 615 is anything like the 625 in, say, the Redmi Note 4X then battery life will blow it out of the water and performance will remain pretty much constant (it never gets "hot hot"). But... so here's the thing, in Antutu the performance never reaches the heights of the X25 at it's hottest/worst.

This Mod on a Google Pixel 2?

With pubg mobile and fortnite being released, I've found myself gaming more on the device than I thought. It gets fairly hot and to my understanding it doesn't have the GPU performance of a Galaxy 8, 9 or Razer phone. I still hit a pretty good frame rate most of the time and I have no idea if there's thermal throttling happening.
More of a "what if" than a serious inquiree.

Use an app to monitor temperatures?

[Benchmark Scores] (reduced after MIUI10 update)

Hi, today after updating my Poco F1 through miui10 OTA update ,I've noticed benchmark scores are reduced marginally as compared to the score on miui9. Still I don't believe in benchmark but I found it unusual!!
On antutu I didn't found much of a difference but
On Geek bench it's way too less as compared to previous Benchmarks in miui9. I ran Geek bench for multiple times but no use!! That score came out to be way less which is not at all close to a SD845 device used to produce.
And I'm using Poco F1 6/64gb varient
*****Please post your Geek Banch scores here*****
I've included screenshots of Geek banch scores for miui9 and also miui10 for the comparison!! [And also included antutu screenshots whete I found no difference at all]

Make sure you're in a cold room. Temperature makes a huge difference

Benchmark on MIUI 10 for Poco F1 (India) - 8.10.25
I don't have AC and even then there is no heating issue that could affect benchmark results significantly, as 2-3k is normal deviation at this level of scores(i.e. 1-2%).
My antutu score improved after updating to miui 10 (8.10.25 currently) it was 265k on miui9 and it is 282k in miui 10.
As for the geekbench i have to test yet allthough i have tested 3d mark if you are interested.
I cant link to post I made on instagram when I tested it because i am new user. search akshay_rajvir user name in instagram and you will find images.
hope it is useful.

just keep in mind mate. Antutu is just a number , I also facing same problems like you but for me , The performance , battery life doesn't change at all.
But if you like to see your performance based on your scores . just try to install sphinx kernel. tell me the scores when you done.

My problem is a converse of yours. i am getting too low CPU scores...around 70k in Antutu. And almost similar in geekbench. Heavy throttling I see. Some users have said their CPU temps go higher than 90 but mine hardly goes above 60. it is throttled at 60.

Hey..... Why is it that after every update geek bench scores keep going down....... Now with 10.3.6.0 people are getting 1400 single core and 4400 multi-core thats shameful for a SD845 but on the other hand antutu score are nice and high 290k so no problem there...... So what is going on,...... And apart from that after every update internet is plagued with users review of worse battery performance...... Is this intentionally being done by MI to push newer devices ???????
