4gb Units?

Sorry if this has been discussed somewhere, but I cant seem to find anything..
I've seen quite a few of these units that have 4 gb of Ram. I'm assuming extra Ram is helpful for any lag that these units generally experience?
For example, this unit from XTRONS website
Why isnt 4gb as popular as the 2gb I'm seeing? what am i missing?
Does anyone have one of these units and can they confirm if the extra Ram makes a huge difference?
Thanks,

It's news
there is a topic about news device (dasaita) with 4Go Ram :
https://forum.xda-developers.com/an...aita-32g-rom-4g-ram-android-8-0-wait-t3702024
I don't know if 4Go ram make a difference,
I Think it's the Soc (PX5(8x Cortex A53)>PX3>RK3188 etc.... )
(there are 8" and 9" with 4GB RAM :

Maybe not a huge difference, but it is noticeable. The 2GB units have occasional audio stutter, which is entirely gone with 4GB (unless this is a coincidence and related to the ROM or MCU). The only remaining audio artifact is an infrequent glitch of a fraction of a second when switching between apps (but I haven't noticed it at all the last couple of days). I have never experienced a "lag" on the 4GB. I don't remember if this was an issue or not on the 2GB. And on the 2GB I tried to update apps while navigating with Google Maps; the navigation crashed and my guess is it ran out of memory. I suppose the 4GB are less popular because they are new and not available in all car specific models.

I see, thanks for the info.. I guess it hasn't taken off yet
Just noticed them showing up for the BMW E46 - looks like they were posted very recently
Does anyone know why Android 7.1 seems to be only offered with the PX3 chips, while the PX5 chips only seem to have Android 6.0 ? What's holding it back?
For example, this listing
- Octa-Core 1.6GMHz CPU, DDR3 4GB RAM, 32 GB ROM for Android 6.0 ;
- Quad Core 1.6GMHZ CPU DDR3 2G RAM +16G ROM for Android 7.1
Why cant the more powerful chip get Android 7.1 ?

mmm really ?
I think it's PX3<T8<PX5
PX5 is Cortex A53 better at same clock than Cortex A7(old) (T8)
PX5 :
8 x Cortex A53 up to 1.5ghz
PX3 :
4 X Cortex A9
T8 :
8 x Cortex A7 (@ 1.6GHz, up to 1.8GHz)
And T8 GPU is old : PowerVR SGX544MP1 GPU (almost old like RK3188 )
whereas the PX5 GPU : PowerVR SGX6110
Antutu benchmark comparison:
PX3:
Overall: 27808
3d: 1220
UX: 13079
CPU: 10293
RAM: 3216
PX5:
Overall: 39047
3d: 9019
UX: 13397
CPU: 12768
RAM: 3863
antutu benchmark of T8 ? ~22500 ...

T8 - SGX544 = 44,8 Gflops
PX5 - SGX6110 = 38,4 Gflops.
They're both 28nm so there's practically no difference in heating, the T8 is used for tablets too. Also software has some say on performance, https://youtu.be/LWVPuKsdkGE

Ordered one if these and seller said ships with 6.0, will send 8.0 when a little bug is fixed.
Received it today and appears it actually is Android 8.0 Oreo. I will post if I discover anything interesting about it.

Please post your impressions. My N7 setup is really slowing down and this unit looks promising on paper!

Thanks for the heads up mum1989!
Ordered the coika 7 " universal and I'm very happy with it. I too was told it was going to come with android 6.0 but it arrived with android 8.0 and with the interface shown. I can also confirm that EazyConnection and mirror link worked on both usb and wifi with a Note 8. Downloading a few apps and will get more into it later in the week.

Keep us posted! I am interesting in swapping out my Joying for one of those also.

Any chance you could review the unit? Would like to hear your thoughts before pulling the trigger.

And it's an MTCE_GS
And it's a lot, lot faster than my crap C200 (5.1) (waze,keyboard run fast, no lag)
I will review a little in few days

Those are NOT Android 8. The UI is a dead and instant giveaway. Android 8 has a ton of new CAR stuff in it, and it looks RADICALLY different than anything earlier.

I just ordered the xtrons te706pl which shows px5 with 4gb ram and android 8.0. I got it off Amazon for $269.99 with free shipping. I was going to go with joying as it's seems to be the most popular company but 4gb vs 2gb is just to good to pass up. I have 2 tablets with the same Cpu, one has 2gb and the other is a 4gb. The 4gb is so much faster and more stable. 4gb just gives the tablet an easier time it seems.

Joying Intel octacore 1.8ghz are little slow, can it be tuned up?

Hey I bought my first Android head unit for 2 month ago a Joying 10.1" IPS 1280*720 Android 8.1 4GB ram Intel octa core 1.8ghz SC9853i, I´m very happy for this headunit it works really great but I have some issues that annoy me a lot.
The speed of the android system on the joying unit is slow compared to my old Asus Nexus 7 2013 tablet, I had some greater expectation of performance because of the Intel octa core CPU 1.8 ghz, but maybe I have misunderstood something
Do any of you know if you can somehow tune up the reaction speed, the device feels slow compared to my old tablet ... Could I install another version of android that might make better use of the hardware?
Best regards Stig

I am having the same issue. Also, I am unable to run new TomTom Go navigation on the Joying radio.

newbie looking to buy an Android 10 head unit

Hi folks,
avid Android user here (mobile phone Samsung Galaxy series) for over 10 years.
I am now looking to buy an Android 10 head unit for my car.
I don't want to do anything fancy – or RAM heavy ? – (just Radio, Navigation via igo or maps, reverse and front camera, maybe torque) but I'm yet unsure whether to buy
Option A: Quad-Core, 2 GB RAM, 32 GB storage
Option B: Octa-Core, 4 GB RAM, 64 GB storage
My only reference point is that I've been using a 3 GB RAM phone for the past 6 years and it has always worked like a charm.
I wouldn't want the device to be heavy on the car battery either.
What would you recommend I get?
Option B, of course, has more RAM, but I've read contradictory information on how much battery quad-core vs. octa-core draw, sometimes that quad-core draws less and sometimes that octa-core draws less.
Also, let me ask: Option A comes with in-built carplay. Do I really need that to connect my Android phone? Would it not suffice to use the Screen Mirroring option?
Help would be greatly appreciated.
RT

I have a unit with quad core and 2 GB RAM( rockchip px3) It's damn slow especially if I'm downloading apps. Download speeds are okay but the installation takes forever.
If I were you I'd take the 4gb ram ( rock chips px5) version. Better performance. There's the 6gb ram as well ( rockchip px6).
Get the best one you can afford.
Do some research on the carplay/android auto features. Some are in built some you can buy a usb dongle to add the feature.

Thanks for the reply and recommendation!
Option A is an 8277L with Cortex A7 operating at 1.2 GHz, the amplifier is an IC 7388, radio chip ST7708.
Option B is a PX5 with Cortex A53 up to 1.5 GHz, amplifier IC 7851, radio chip TDA 6686.
I was looking to buy the one with more RAM, but hesitated, because
1) Option A supports video output
2) Option A has integrated carplay
and that alone had me wonder whether – even with lower RAM, ROM, and set of cores – this unit was the better one in terms of being tried and tested.
Now if you say, I should definitely take option B, I can get a dongle on top for android auto. Yet I was wondering if it's necessary at all because the head unit supports screen mirroring?

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?

Joying Snapdragon 625 vs Unisoc UIS7862 head to head

New user here.
The new Joying headunit with Snapdragon caught my attention, as it runs a Snapdragon 625 chip instead of the Unisoc UIS7862, and command a higher price (£55 diff) . So I did a little more research on their respective performance.
Against my expectation,, almost every metric and benchmark puts the UIS7862 ahead of the Snapdragon 625 by a decent margin, it is almost 4 years newer and on a more advanced 12nm node (instead of 14nm).
More to my suprise, Snapdragon 625 only supports upto 3GB ram, so the 4GB installed in the head unit would not be fully utilized.
Am I missing something blatantly obvious? Should I look at more than just specsheet and benchmark? I am very confused as to which version of the head unit would preform better in the long run. Which one would you choose?

Hi there.
I am currently going down the same rabbit hole, trying to get a new head unit for my 2011 Ford Escape. I even found the same comp pages that you listed in your post.
I have asked Joying support last week some of the same questions you asked here, and they didn't offer any useful details and their one-sentence emails about this topic are very cagey.
Mainly - why is the new Teyes-like UI that they have on the Snapdragon not available on the clearly superior 7862 units, and only on the slower Snapdragon 625? They didn't answer that. If the new UI was available on the 7862 I would not even be doing this research, really. That's the only thing that has me going back and forth. That, and the horrible USA LTE band support on the 7862.
The fact that the slower, less RAM 8xA-53 unit is more expensive than 2xA-75/6xA-55 unit is puzzling.
Saab Unleashed has excellent reviews of these units:
Snapdragon
7862
he reviews the 1920x1200 version, which is yet another dilemma for us
It seems that likes the Snapdragon version mainly for the UI, and in the comments he mentions that the performance is about the same as the 7862 version. Weird.
Since you wrote your post in November 2021 - have you decided on one of these? If so, what was your experience like?

I sold many 7862 unit without problem. Recommend 7862

I bought the UIS7862 version, it is running flawlessly with AGAMA launcher. My decision was simple: first, the Teyes launcher seems more buggy from other review, compare to AGAMA launcher which is tried and tested. Second, I am not paying 20% more for 25% less performance and 25% less usable ram. It just does not sit right with me.
I would personally avoid the 1200p as text and icons looks tiny on a higher res screen, which makes it very hard to use while driving.

That all makes perfect sense.
Thanks for the note about the AGAMA launcher vs Teyes. I ruled out Teyes unit itself but because I liked the look of that launcher I was still considering the Snapdragon Joying unit with the Teyes-like Launder. But the specs and price of that unit compare to the 7862 version just don't make sense.
I will be ordering the 7862 version as well.
Thanks.
