8.4 do not have hmp - Galaxy Tab S General

just wonder about that.
some say exynos 5420 support hmp by theory, yet samsung disable it, while 5422 / 5430 / 5433 support in reality.
i check it by cpuz, it clearly shows cluster switch and only 4 cores can be use at the same time.
5433 (note 4)

5430 (samsung alpha)
5422 (ODROID-XU3 Lite System)
5420 (note3)
even note3 get lollipop update, kernel is still a 3.49, no hmp will be given, it shows only linux about 3.10 can support hmp.
and i don't think samsung will update kernel for us.

Heat and battery-life wise I do not reckon they would enable this.

What is hmp?

Ah this conversation again. The exynos5420 was supposed to support hmp but ended up being broken and as such will never work. Sorry guys.

Yep. According to AndreiLux it is impossible to be implemented for our Exynos5420. He has stated the exact reasons why in various posts on the Web.
I have seen evidence of working HMP on Samsung Exynos5420 at one of the developer shows a year or so back though, but doesn't necessarily mean a software patch will make it work here. Hardware needs work too, which we can't change. ...

CPU-z
i just noticed something else wrong with my galaxy tab s 8.4 the CPU-Z info "http://i.cubeupload.com/3LpKj0.png" the exynos 5420 suppose to be with 4 slow cores at 1.5 and 4 fast cores at 1.9 but on this info from CPU-z it shows them all as 1.9 somehow , and also here "http://i.cubeupload.com/vUgZnP.png" it shows the screen dpi 320 instead of 359 . is it the same on your device as well ? can you share any screenshots or info thanks im using CPU-z 1.1 btw

Either the app is wrong or you have the later model with Exynos 5433.

TYTN 2 Kaiser MSM7200 faster than Samsung 500Mhz?

After quick view from some website , I found that the MSM7200 which is assembled in Kaiser is faster than Samsung 400Mhz and 500Mhz Processor.
Samsung 500Mhz(P3600i), Samsung 400Mhz(Dopod D810),TYTN II(MSM7200)

Below is my summary of the test statistic above.
CPU Index
SAMSUNG 400Mh - 13XX
SAMSUNG 500Mhz - 14XX
MSM7200 400Mhz - 15XX
Graphics Index
SAMSUNG 400Mh - 9XX-12XX
SAMSUNG 500Mhz - 12XX
MSM7200 400Mhz - 3XXX
According to the statistic, seem the MSM7200 is faster than the Samsung 400 and 500Mhz CPU £¬ especially Graphics Index¡£ But in real world , how come it is underperformance and slower than 838Pro ? especially gaming , video and Emulator . Is the software optimization issue? direct draw issue or the test results are fake?

Who knows what exactly these tests are actually testing. Everything, but the msm7200 devices, are certainly using their ATI chips.
Didn't MSM7200 had like a duo core type of working???
And cause not working 100% is cause of lack of drivers. But will be fixed end March.

The driver is not a driver to enable ATI imagion.
Hopefully the new "Driver" can much improve 2D rendering performance for gaming , video and WM GUI.

Do you know if it modifies kernel or interferes with setCPU?
I sent them a message about it, let's see what they say.
No it don't mess with kernel, I also don't think it adjust cpu frequency as I think it would need root permission, which this app don't require.
Sent from my HTC One X
yepp, I installed it, and looks like what it does is that it organises when apps connect for sync and update, which sounds really good, and others don't do that.
yep, they said:
Thank you for your enquiry.
BatteryGuru does not modify the kernel or CPU settings in and way.

[SOLVED] Overclock over 2.89GHz - possible?

Hello,
I'm making custom kernel for Z3 and Z3 Compact,
and I tried to get overclock to 3.0GHz.
I edited msm8974pro.dtsi according to Faux123's commit
and also edited msm8974.dtsi in this commit (later I changed to 3.2GHz but didn't changed).
"3033600" should be appeared in CPU freq,
but all I get was "2899200", which I didn't write in the code.
Strangely, there is 3033MHz in CPU voltage adjustment.

Is this hardware limit, or software limit which we can break?
I don't really need 3.0GHz, but I want to know the limit.
[EDIT]
Now there is possibility for over 2.89Ghz!
Thanks flar2's patch.

I'm not really sure it regards to the above. However, due to overclocking PC hardware myself, there is always a synthetic limit.
For example:
Some devices will be able to reach higher clocks than others.
How do other Snapdragon 801 devices perform, LG G3, Moto X 2014? Take that as benchmark.

This is the LP Kernel Repo. I also added GPU OC in case you care, just check the commits
Actually the 2.89GHz Value should be 3GHz, as it also get's refered to on the Voltage Table in Faux Clock (3033MHz) but the Clock only goes up to 2899,2MHz. Don't know what this is related to.
BTW: The main work for this was done by @faux123 for the HTC One M8, I just adopted it for the Z2 @AndroPlus Let me know when you found a solution, I am glad to fix this for the Z2 too.
Now I found solution of flar2's commit!
We can go over 2.89Ghz... but it's not stable.

Could someone explain to me what the third value in < 2265600000 1120000 738 >; in msm8974.dtsi means and how this third value is calculated? Thanks in advantage

top 10 in 2013 VS 2014
Why note 4 in 4th
And why it score only 44669
exynos 7 better than this
Shame in real life the Note 4 (Snapdragon version) is a lot slower than the benchmarks would suggest.
Sluggish OS performance and sluggish game performance put's it well below it's place in the benchmarks in my book.
HTC One M8 at the very least frankly shows it up when it comes to speed and fluidity.
A rom, debloat and tweaks makes model f a bit more smooth. But it's sad that you have to. Old N5 or M7-8 is another league, so it's down to TouchWiz. For some this a deal breaker and for some not. I hope that A5 will change this a bit.
You never know

Pftt...nonsense antutu score of only 44k. I'm getting around 51k on my N910C exynos version.
Under 45000? People must be bench marking in a sauna. I will always get 49xxx-50000.
This was at room temp and device temp was normal.. Not sure what was going on here but I mostly get around 48-49000
Sent from my SM-N910F using XDA Free mobile app
Stock N910C
I get 49000 to 51000, stock rooted, 910c
N910F stock nk4.

That's scary! Did you put it in the freezer just long enough for it to reach 0C and then get the phone out to do the test....
My Exynos was always at 49k, now after the ultimate kernel and 1080p resolution it gets 52k every time. 45k? That must be SnapD.

LOW BENCHMARK SCORE ONE UI 3.0

After ONE UI 3.0 the geekbench benchmark of the S20 FE 5G SNAPDRAGON 865 is very low, comparing to the past ONE UI 2.5
The multi- core is the worst.
Been getting results like
SINGLE CORE: 851
MULTI CORE: 2783
Weird that when Europe gets the first samsung with a snapdragon version available, it gets bottleneck like this?
Seems more like samsung is trying to hide the performance difference between EXYNOS and SNAPDRAGON. The multi core performance now looks like exynos 990

Unfortunately... Not so global... Especially for the US.
Although your multi-core score is a bit under 300 less than mine, your single-core score is only 13 less than my S20FE running OneUI 2.5. It could very well be cases of testing anomalies, installed software or testing environment causing differences. Or... It's probably just a case of new OS version that hasn't been entirely ironed out. You still appear to have slightly better scores than Exynos 990 (about midway between Exynos 990 average and my average on multi-core by the look of it), so unless you notice a significantly worse battery life, I wouldn't assume that Samsung has succeeded in dumbing down the SD865 to Exynos levels yet. Have a good one!
i'm having the same issue, i posted about it on reddit.

i'm only getting 2600 for multicore (base s20 - snapdragon 865). previously i got 3000
