Confused with Quad core and Octa core

Please help me to choose ....should i buy a 2.5GHz processor quad-core Qualcomm 8974 Pro or an exynos octacore (Quad 1.9GHz + Quad 1.3GHz) variant of s5?

You should buy the model that best fits your needs. Each one has some advantages over the other. The primary determinant for most people would be which model is best supported by their carrier.
Speaking only for myself, I would never buy the Exynos (octacore 900H) because there are many more Qualcomm models (quadcore e.g. 900F) and as such they are much better supported by custom ROMs and Developers in general.
There have been countless threads about this, full of useful informarion. It's a good habit to search before posting. Have a look and you'll learn a lot about the phones that you are contemplating.

I have to agree with you, in the most pain full way. I had no choice and I bought Exynos. For 4 months I have been waiting for a custom rom. I continue waiting. There are only two or so, samsung debloted roms.

Qualcomm quad core better... More Dev support.

[Q] [DISCUSSION]Note 4, 64-bit, and Android L

Hey guys.
I was searching on internet about Note 4 and I found an article about note 4 and Exynos 64-bit processor. Immediately I jumped xda to talk with you about this. (Link to article)
I've just found a topic here which is nearly same, but I have some other questions to discuss. (Link to the other topic)
So as you guys know there is two versions of Note 4 which is Snapdragon and Exynos. As far as I know Exynos processor version is accually 64-bit. (I'm not sure if it's true or not.) We all know that Snapdragon version is way developer friendly so it will have more custom staff. In the other hand we might have a 64-bit processor which is marketted as a 32-bit processor by Samsung. (Again as far as I understand from the article above.)
So here is my concern. I don't know if devs wil work on snapdragon or Exynos but do you guys think that Note 4 Exynos can be used as 64-bit by the customizations done by devs since Android L supports 64-bit?

SoM board upgrade from RK3188 to RK3288

Now that Joying seems to be pretty close to the release of their RK3188 version of Android 5.1.1 lollipop, do you think we could start some kind of petition to them to upgrade to RK3288? maybe it wont be so hard after all the development done to bring 5.1.1 over RK3188, since RK3188 dont have official support for lollipop they are using an old kernel and more than likely RK3288 code that has official lollipop support from Rockchip, like other custom lollipop roms for the RK3188 out there.
May be if we show them that there is a real demand, they will go for it, after all, the demand for lollipop made them create this hybrid rom for backward compatibility with their existent hardware, wich could be a lot harder that work on an already officialy supported SoM with and SDK.
I know that SoM swaps have been done before from Rk3066 to RK3188 and the gains where huge... so why change the whole Head Unit when we just need a new SoM, also I've heard of providers that actually sell the replacement SoM from RK3066 to RK3188... so why not try between many of us to ask for this next step from Joying, with faster Boot times(this is a must), more CPU processing power, more RAM and better GPU?
What do you think?

I'm very curious about this as well

Excellent idea. I just sent away a Facebook message to Joying asking them about this.
RK3288 would indeed be a major upgrade. Cortex A9->Cortex A17, Mali 400 -> 700 series, dual channel DDR3, eMMC4.5 and most likely Bluetooth 4.x support etc.

If you want a real upgrade, get them to move away from Rockchip all together.

Joying doesn't make the SoM's, it's Rockchip that places them on the market . basically no head unit manufacturer can make more than a carrier board, they do not have the knowledge for more.

They sell RK3288 SoM upgrades: https://www.aliexpress.com/item/Firefly-RK3288-Reload-CoreBoard-Quad-core-A17-1-8GHz-Support-Ubuntu-Android-HDMI2-0-4K/32626693047.html?ws_ab_test=searchweb0_0,searchweb201602_1_10000560_10000606_10000561_10000073_10130_10000074_10000608_10000709_10000660_10000704_10000703_10000175_10000509_10000507_10000505_10000558_10136_10000068_10000552_10000369_10000063_10000365_10000367_10099_10000663_10000665_10096_10000669_10000569_10000097_10000094_10000337_10000723_10000090_10000147_10000091_10000726_10000144_10000339_10000729_10000150_10000679_10084_10000678_10083_10000676_10080_10000153_10000673_10082_10081_10110_10111_10112_10113_10000535_10114_10000534_10000089_10000086_10000710_10000083_10000349_10000690_10000135_10000716_10000693_10000080_10078_10000717_10079_10077_10000688_10073_10000684_10000140_10070_10122_10123_10126_10124_10000546_10065_10068_10000746_10000782_10000743_10000132_10000033_10000786_10000030_10000026_10000126_10000023_10000129_433_10000123_10000696_10060_10062_10000699_10056_10055_10054_10000632_302_10059_10000738_10000120_10000774_10000734_10000020_10000778_10000013_10000117_10103_10102_10000016_10000114_10000111_10052_10053_10107_10050_10106_10051_10000621_10000384_10000763_10000629_10000766_10000101_10000100_10000576_10000770_10000579_10000104_10000045_10000578_10000375_10000108_10000377_10000758_10000612_10000390_10000613_10000042_10000750_10000592_10000754_10000594_10000039_10000587_10000036_10000389_10000187,searchweb201603_9,afswitch_1,ppcSwitch_5,single_sort_0_price_desc&btsid=ef5e601f-b560-425f-a799-d4145b3ca2f9&algo_expid=54085468-96d0-47dd-9e78-ef975803d812-1&algo_pvid=54085468-96d0-47dd-9e78-ef975803d812 Couldn't you just swap them without any trouble?

Would that fit a Rk3066 800x480 MTCB unit?

HU with 2gb w/o Intel Sofia

Hi everyone,
I'm looking to buy my first HU and after reading the forums for a while I'm undecided what to pick.
It looks like the Intel Sofia platform is the current recommendation - it comes with 2gb, the CPU is powerful enough and it has some support for fastboot. However from what I can tell there's no custom ROM for it (Malaysk is only for RK3x88 series) which is kinda of a big minus for me (since one is at the mercy of the seller).
Am I missing something? From what I can tell the RK3188 and Sofia CPUs are more or less identical in terms of performance, the RAM being the big difference.
I'm looking for stability (not going to play games or videos on the HU - I just want waze and probably the radio) first so a slower, older CPU with a solid community and ROM behind it fits my list.
Any suggestions?
Thanks,

Theres no "current recommendation", its all down to personal opinion. The Sofia units are ok (both MTCD and "009" versions), so are the Rockchip RK3188 MTCB/C/D ones which bring the benefit of custom ROMs. The Rockchip ones dont come with 2GB as standard and (in Lollipop guise at least) they need it, but that can be added relatively easily. However, the latest MTCD versions and Klyde's versions (probably MTCC but no ones sure at the mo) use the octacore Rockchip PX5 (RK3368) so should offer better performance than the Sofia or RK3188 units.
Your only option for custom ROMs at least at the moment are the RK3188 units. Another benefit of the MTCB/C type is that theres a particularly good audio mod that gives control of the audio chip to Android, although youd have to be able to solder to do it.

Thanks for the reply. Soldering extra RAM is not something I can do easy - I lack expertise and getting hardware in EU tends to be expensive and slow; I'd much rather pay extra (and wait) to have it built in the factory.
I'll keep an eye on the RK3368 boards.
Any idea whether these would be ROM friendly ?

I m in the EU and I got my RAM for about $30 in the group buy, theres a thread open at the mo, they took 3 days to arrive. It would just be a case of finding somewhere to do the soldering for you, thats what most people have done.
If the Klyde PX5 units are MTCC it should mean that anyone with an MTCB or MTCC unit currently could simply change their SoM for a PX5 one, we just dont know yet (the original MTCB units were dual core RK3066 and a lot of people just upgraded their SoMs to the quadcore RK3188). Well, we dont know until someone buys one - theyve been on sale since November, but if they are MTCC an upgrade to a PX5 would be possible if you bought an MTCB or C RK3188 and upgraded the RAM, then youd be able to sell your RK3188 SoM with 2GB RAM as it would be quite sort after due to the extra RAM . . IF theyre MTCC that is.
All that may be a bit long winded for you but at least youd have access to a custom ROM as you wanted with the possibility of upgrading in the future to a version that is more likely to have support from current MTCB custom ROM makers (I m assuming theyd eventually upgrade to PX5 units themselves and start making ROMs for them).
Or you could just buy a Klyde PX5 unit now and have the most up to date unit, but with no custom ROMs support yet :

If I sound MTCB/C biased, well I have 2 so I am. But from what I ve read the Sofia MTCD and 009 units are good too and at least theoretically easier to make a custom ROM for because Intel release their source code, unlike Rockchip. But no custom ROMs exist as yet.

Thanks again!

Klyde's unit indicates support for Android 6.0.1 while Intel's on 5.x and most MTCB on 4.x. Reading the forums I thought a MTCD board is required for android 5.x but it looks like that might not be the case - I guess in the end it depends on the manufacturer.
Btw, I read that one nice thing about Sofia is the fastboot feature which is not present on RK31xx/30xx units - not sure whether this is SoM or MCU specific. Do you have this feature on your units?
I like your idea about using an existing, tried-out platform (RK3188) with upgraded ram and custom ROM - it was my initial plan but the whole prospect was off putting.
I'll ask around to see how complicated/expensive would be to do the soldering.
Cheers,

Lollipop has been out for MTCB/C for about a year, this applies to ALL manufacturers and all RK3188 units, Klyde are the only ones who do Lollipop ROMs but the ROM can be used on ANY MTCB/C RK3188 device because they all use the same SoM. Some people find it laggy (I dont) but the 2GB RAM sorts that. Boot time is 20 - 30 seconds depending on what ROM you use, but there is no specific fast boot feature.
I did a group buy as ordering just 2 modules is expensive, but read the second RAM group buy thread in the MTCB hardware mod section and pm the guy who did it I think there may be some left.

Ownice Octa Core 2gb/32gb

Hey everyone!
I am looking to buy this Ownice model but I am torn between it and the Joying 2GB Intel model.
Here is the Ownice Octa Core I am specifically looking at:
www dot aliexpress dot com/item/7-Full-Touch-Quad-Core-Android-4-4-Unversal-2-Din-Car-DVD-Player-GPS-Navigation/32376821907.html
Here is the Joying that I am torn between:
www dot aliexpress dot com/item/2G-32G-New-Android-5-1-Quad-Core-Universal-Car-Audio-Stereo-GPS-Navigation-Double-2/32753889718.html
The other Ownice thread seems to be more about the quad core version so I thought I should start a new thread dedicated to the Octa Core model, as they seem to have quite a lot different about them.
I am hoping people can give feedback about both models to help me make a decision to commit to. What are the pro's and con's you are experiencing. What pitfalls should I watch out for.
These 2 models seem to be the most popular machines on XDA right now, if you guys think there are different units I should be considering, please mention them.
Thanks in advance again for your help.
