Underclocked headunit+os version? - Android Head-Units

Hi,
Just got new android headunit, this one https://www.aliexpress.com/item/4000808902548.html model T3-CP. advertised as 4-core ALL WINER T3 1.5GHz Cortex A7. But cpu-z says that processor is 1.2Ghz and actually runs on 1.0 Ghz. Unit works mainly as adverticed and expected, just a little bit slow but just wondering is there way to change cpu speed to 1.2Ghz which should be actual cpu speed? Also wondering what is actual os version on headunit? Kernel 4.9.118 says it is Android 9.0 but api level 27 says it's 8.1? Also does anyone know how to find developer options on those Prelingcar headunits? Far as i know it should be quite popular brand? Thanks

If you read the Aliexpress description carefully, it says it is a Android 8.1 with 1 GB RAM. The kernel version cannot be used to derive the Android version.
Yes, the Android Settings version information is faking to be Android 10 and 2 GB RAM. Never trust such a screen on these Chinese HUs.
CPU-Z is using the kernel interfaces to find out max CPU frequency and current frequencies of the 4 cores. Note that the kernel adjusts core frequencies on the fly, dependant on the CPU load. So you will not see 1.2 GHz often and should see lower frequency typically.

Actually device has 2gb ram, atleast displayed by cpu-z. Cheaper model T3 has 1gb, but this is T3-CP. Yes i know that unit do not have android 10 even it says so, but just wondering what version it actually has.

[Q] apps that monitor cpu

Anyone knows why all apps i downloaded (cpu-z, monitor cpu, setcpu) only show max mhz at 1300?
i have a sm-g900h with arm15 cortex r2p3 , i understand that is an octa core with 4 cores at 2.1 ghz and 4 at 1.5
It is a phone problem or all these app don´t support the system?

It's likely most app do no "fully" support this new octa-core. I would suspect they only show the little CPU 4 cores @ 1.5GHz, however seeing 1.3GHz as the max is weird. In S4 octa-core, the max frequencies was used by both CPUs and frequencies below 600Mhz where meant to be used by little core (600Mhz being 1.2GHz on the little CPU, 700Mhz being exactly that on the big CPU), so there might be some similar tricks on the new S5. This would mean the kernel would only show 4 cores at any point in time.
Have you tried Android Tuner, it can adapt to any number of cores automatically (a little down arrow allows to switch to multi-core control) ? If you try it, can you post a screenshot here? I intend to buy the Galaxy S5 with 8 cores for testing purposes, so I'd be interested by first-hand screenshots, if any. You can check and post screenshots of the main CPU tab and also the Times tab which will show available cores timings for each frequencies.

New Headunit Erisin ES9015

Hello,
I bought this HU,
http://www.erisinwholesale.com/spec...es9015v-8-vw-android-444-car-dvd-gps-413.html
Now is my question does anyone now it and it´s special Rockchip?
Im pretty not sure what it is, maybe tomrrow I can make some Screenshots.
CPU-Z tells it is an RK3066 with 1,4GHz.
It´s Tuner come with an working AF function.
I think it is the cheaper Rockchip 3066 T variant, the normal dual core and quad core works between 1.6 and 1.8 GHZ, the cheaper dual and quad core T cpu only runs on 1.4 GHZ.
If i look on the specifications i see strange things, they advertise a dual core bud showing a quad core cpu.
Very confusing
I searched on wikpedia an I thought it could be this one.
The RK3188T is a lower-clocked version of the RK3188, with the CPU cores running at a maximum speed of 1.4 GHz instead of 1.6 GHz. The Mali-400MP4 GPU is also clocked at a lower speed. As of early 2014, many devices advertised as using a RK3188 with a maximum clock speed of 1.6 GHz actually have a RK3188T with clock speed limited to 1.4 GHz. Operating system ROMs specifically made for the RK3188 may not work correctly with a RK3188T.[39]
Maybe someone nows if it is upgradebale with the RK3188 SOM Card.

Choosing SoC MTK 8127A vs PX 5 RK

Hello want to change my aunt and I am in big trouble
My choices are an Android device based on MTK 8127A from ATOTO but that come with 2 GB of RAM or a regular one based on PX 5 which come with 4 GB of RAM.
I understand that the MTK car goes devices are a little bit rare
So what to choose:
ATOTO with a MTK PROCESSOR and 2 GB of RAM, pretty good support and rom updates or a PX 5 ?
Which is faster and more stable?
Thank you

From what i have heard, MediaTek has better reputation than Rockchip. Which one is more stable / faster depends on how the SoC is integrated into the platform, how the Software Governers control the clock rate of the SoC. So this is difficult to answer strictly based on the SoC chip itself.
SoC Chip: MTK 8127A
Soc-based Quad-core 1.5Ghz Cortex A7 CPU
GPU ARM Mali-450 MP4 .
System Version: ATOTO AICE OS 9.4, which is developed & customized based on Android 6.0 Marshmallow OS;

PX5
8 core ARM Cortex-A53 (ARMv8) 1,5 GHz
GPU owerVR SGX6110 jusqu'à 600 Mhz (OpenGL 3.2, OpenGL ES 1.1/2.0/3.1, OpenCL, DirectX9.3)
Android 8.0

but there are also :
PX6 ! devices (but it's news no more info a this moment) :
Android 8,1
CPUX6 RK3399
2 Core cortex A72 2ghz
4 Core Cortex A53 1.5ghz
RAM: SAMSUNG DDR3 4 GB
https://forum.xda-developers.com/an...-android-unit-cortex-a72-four-cortex-t3847427
And A72 Core is a lot better than A53, and A53 is a little bit better than the very old Cortex A7
I agree with @mum1989 that A72 and A53 CPU cores have much better specifications than the A7. If the applications you run on the head unit can take advantage of the ARMv8 instruction set or if the workload can be distributed across the cores, then PX6/PX6 SoC may well perform better than MTK8127A. On the other hand, in my day-to-day use of ATOTO A6 Pro which uses MTK8127A, I have never observed it to be slow or stutter or otherwise show signs that older A72 Core was limiting the end-user experience.

Need an advice with processor selection.

Hi, last year i have bought HU with following specification:
SYSTEM (Android 6.0.1) 1GB/16GB
Allwinner QUAD-CORE T3 p3,
Mali-400MP2 .
Unfortunatelly it turns out horribly slow - I have rooted it and tried to speed it up, but without success.
Now I'm considering to buy another one (cheap), I need HU to normal use (google maps + music app + radar warning application) .
Here are my selections:
Android 8.1 1GB/16GB
quad-core T3 K2001M
GPU: Mali-600MP4
Android 8.1 1GB/16GB
quad-core MT8227L "1.3-1.5"
GPU: Mali-600MP4
Most units which I'm interested have these two processors some have also 2GB RAM. Which is better selection? Maybe i should choose someting with 8-core or 2GB ram?
Regards.
The processor is not the only thing that affects the speed, the amount of RAM matters too. Everything you listed has a gig of RAM, that is just too low for today's Android with all the services running in the background. Look for something with at least 2 GB, 4 would be better. The processors you're looking at are no powerhouses either. First they're all 32 bit and very obsolete. Also Allwinner is barely a decent processor for the money. Something from Rockchip or Intel would cost a bit more but you'd get more enjoyment out of it. If you have to keep it cheap maybe a PX30 with at least 2 GB RAM would be a good choice.

The man is completely right. Nothing with 1GB will perform.
2GB is enough. 4 GB is better.
I agree that 1GB is not enough for todays Android, but this is still car device, not phone. I don't really want to spend lot of money . How about this ?
OS: Android 8.1 Go 1GB/16GB
CPU: Intel 8-core 1.872GHz Intel IA processor
GPU: with Mali-T820 8-core GPU
OS: Android 8.1 2GB/32GB (i think they will be able to install GO version too.)
CPU: High quality MT8227L Quad-core 1.3-1.5 GHz Cortex-A7 processor
GPU: with Mali-600MP4 Quad-core GPU
both fit to my limit 150 $ .

a bit stubborn? The first is 1GB. If 2 persons advise to go for at least 2GB: what more advise do you need? If you had searched this forum in advance, you would have seen that everybody advises against 1 GB.
choose and suffer, or choose and enjoy.
That's a really low budget. A $150 will buy you a nice Pioneer or Kenwood traditional stereo or if you want more features get a cheapie Dual or other low end brand. At any rate you will enjoy your choice better then. Those Chinese Android radios have always been a bit of a kludge. It's only in the last couple years that they've been getting almost decent and that's from having a proper amount of RAM and better processors. The one thing that hasn't improved is build quality, they work ok but there's no telling for how long. OTH they're a lot of fun if you can afford it.
The second option you listed is definitely low end but might work good enough. Like Surfer63 said do your research! Don't expect someone else to tell you what to buy. For that HU you can start here. On that first page there's a link to 4PDA too.
Believe me 150$ for car radio is quite a lot in my country To be honest initially I thought 100$ will be enough for my modest needs... I know 4pda I have studied most topics regarding Allwinner and partially this mentioned above . I have some experience with such devices (with 1) I could try to flash it but I have no time for that. In the mean time I have found that there are HU which are fitted to car steering panel better than universal one so decided to buy another. I did not expect that someone tell me what should I buy, however all yours remarks are very valuable for me. Ok I'll read a bit more and buy something, and maybe give some feedback.

Which one is better? 8227L vs allwinner sun8iw11p1

Looking to get an android head unit. Visited a couple of local shops and ran CPU-Z on the android units. They're both same price (quite cheap) but I'm not sure about underlying hardware quality and future update possibilities/mods?
First: 8227L (ac8227l), Android 8.1 Go, Cortex A7-1.12 Ghz (quad), 1 GB Ram, 12 GB Rom, 5 band Equalizer
Second: AllWinner A23 sun8iw11p1, Android 9, Cortex A7-1.6 Ghz (quad), 1GB Ram, 12 GB Rom, full-band Equalizer
Apparently second one is better, however, I checked online and allwinner a23 is quite old hardware (from 4-5 years ago), but it is faster. Also, its running Android 9 but not the "Go" version, so it might be more taxing on the memory. I like everything about second, except that the Home screen has icons with white rectangle background so there is a lot of white on the screen and I fear it will be too bright to use at night.
First one has slower cpu and android 8.1 go, however, a lot of the posts I see on this forum are related to 8227L.
Which one should I go for? Is one better than the other in audio quality?
