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.

8 cortex a7 are the same power comsuption than 4 cortex a8, the same or less that 4 a9, and less that 4 a15, and have more ghz in total, so it would be a good idea to make this, mtk make cortex a 7 processors and the 4 cores device with it are the same speed as google nexus 4, so i think that it will be a good idea

Just think of AMD vs INTEL
More cores vs. higher performance per core
Don't get fooled by the market gimmick and I prefer the A9/Intel way any day.

sorry, but mediatek stoled my idea, they are doing an exellent job with not more cores, it is same performance with more cores with more battery saving and making a good architecture no like amd, amd isnt bad, they chipsets are wrong built, bulldozer stink
hello, I am ready to buy a android tv but now I don't know which to buy, there are 2 versions of mk808b, one is dualcore with a rockchip rk3066 cortex a9 1.6 ghz and the other is amlogic s805 cortex a5 quadcore 1.5 ghz, I know that more cores is not always better performance, please can you say me which is better and why? thanks in advance
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.
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.
Do anyone have a custom kernel for the mediatek cpu cores? I want to overclock max frequency for cpu, gpu and memory, and have no experience making my own.
My unit is A6YVW721PRB, pro 6 for the VW cars, with buttons.
The cpu is MTK 8127A Soc-based Quad-core 1.5Ghz with ARM Mali-450 MP4 GPU.
Android 6.0 marshmallow OS.
Edit: is this the wrong place for such request?
