Mediatek MT6575 SoC - how good is it ?

Hello,

I have recently learned, that many high-end Chinese Android
smartphones are based on Mediatek MT6575 SoC, but after looking into
community's database I have found zero info about them.

And community's evaluated CPU database:
http://rhombus-tech.net/evaluated_cpus/

So...
1. What is the bulk-price of those MT6575 SoCs, and what are the main
parameters ?

2. Could AllWinner A10 work in smart-phones ?

New SoC, MT6575:

Currently i am using a 6575 phone, I9200, a galaxy note clone, it has
3200mHA battery, so i need to charge 4 or 5 days once, but usually i
don't play much with it, just normal daily usage. It works with dual
sim card, one wcdma and one gsm The pvr531 inside the soc's
performance is better than mali400, from my using experience, though
the ppt from arm shows that the pvr531 is worse than mali400. The 6575
single chip contains bandbase, bluetooth, wifi, gps and fm, very high
integration.

It's brother 6577, is a dual cortex-a9, and pin-to-pin compatible chip
with 6575.

Yes, but not A10, but sun5i, i am not sure if it's already on market.
If not, it will be soon.

Including the analog parts ? + Analog audio ?
GSM radio analog circuit is integrated into 6575 ?

GSM radio analog circuit is integrated into any Allwinner products ?

Allwinner A13 (sun5i) supports only 512 MB of RAM, which may become a problem.
Rumors say, that Android 4.0 is unstable on 512 MB of RAM, and kills
applications at random (due to lack of RAM).

Can anyone confirm or reject those claims ?

There is even MT6577 available, which is dual core Cortex-A9.

Both of them include 3G modem, GPS baseband. Graphics is SGX531.

Re: Mediatek MT6575 SoC - how good is it ?

Hi Alexey,

The biggest problem with MTK as I know is the source release.

As I know there is not any source release from MTK even for manufacturer.

MTK just provide PCBA limited information + Binary to manufacturer.


So there is not way to work with MTK.

 in a word, yes.  GPL violations on an endemic scale.  the taiwanese
companies have a habit of completely doing the design work, and all
the software (regardless of whether it's GPL'd or not) and all the
manufacturing, on your behalf.

 i heard that haralde welte has been working on an education programme
for taiwanese companies, for some considerable time.  the "policy" of
assuming total control over the entire product is borne out of a
complete failure of chinese companies to cope with or aid or assist
with the product development in any useful way.  the amount of
resources consumed by their "questions" is merely a financial
distraction.

 in the case of smartphones where the binary GSM Radio firmware is
running on the CPU (such as with the MT6575 and also with the ST
Ericsson U8500 "Nova" series and above) there is an additional
problem: FCC and other Certifications *require* that there be no
"modifications" made to the O.S.

 the fact that it is possible to hack into such phones very very
easily and do things like re-program the power output of the GSM Radio
ROM simply by poking a memory location, as is known to be the case
with some of the lower-cost HTC Smartphones, thanks to the
reverse-engineering done by xda-developers engineers, seems to have
completely escaped the FCC and other Certification organisations'
attention.

 but anyway: the Certification organisations are at least trying to
keep us "safe" from having our heads melted by radio waves, or our
ears blown off by lithium battery fire, and i kinda appreciate their
situation.

 bottom line is: using a smartphone CPU with an integrated Base-Band
for any mass-volume Software (Libre) Project is fairly unlikely, but i
*do* want to tackle it at some point, once there are enough funds
($Nm) to do so.
