Is there any hope for the ATM7029?
Recent firmware upgrades for my Hero II have brought some speed improvements; Can Actions Semicondutors squeeze more performance out of it? Or is this CPU doomed?
ATM7029: an ARM Cortex A9 or A5?
I've heard rumors that the quad-core CPU of the Actions ATM7029 might not be an ARM Cortex A9 as claimed.
It could be an ARM Cortex A5, perhaps modified and improved...
What does this mean?
Well, the A5 is more energy efficient, but also older and slower per core and per clock (A9: 2.50 DMIPS, A5: 1.57 DMIPS).
Therefore, applications that don't take full advantage of all CPU cores might actually run faster on a real A9 dual core.
How can we find out if it is an A5 or A9?
Benchmarks should be able to tell. Also, if you have an ATM7029 based tablet, take a good file manager (doesn't even require root) and open the file /proc/cpuinfo.
Or from a terminal, you can run the command "cat /proc/cpuinfo" to display the contents of the file.
Here's what it looks like on an Amlogic AML8726-MX (dual-core Cortex A9):
The "CPU part" number identifies the CPU type. The ARM Cortex CPUs should have 0xC0? with "?" being the type number, e.g. 9 for an A9 or f (hexadecimal) for an A15.
The ATM7029 supposedly reports 0xc05, thus an A5.
Can anyone here with a Hero II confirm or deny this?

You can't expect too much from it, treat it as a dual core with a useless GPU. Useless because unless the soc won't use a popular GPU game support will suck.
If you don't care about aosp ROMs and games it could be an alternative to other dual cores.
Just to let you know, ainol and zt amlogic MX based have 4.2 aosp ROMs since December after the source code has been pushed on Google's repos

Unfortunately this. If you don't need a tablet for gaming and dual-core performance is sufficient, the ATM7029 is pretty okay. Basically, I just wanted a 7" 1280x800 tablet with microSD slot for running Perfect Viewer which is why I got the Venus. Its resemblance to the Nexus 7 chassis-wise also played a part. If you actually care about gaming performance, etc, the ATM7029 should be on the "must avoid" list.You can't expect too much from it, treat it as a dual core with a useless GPU.

Got it really cheap. I don't care much for 3D gaming and I don't need GPS. I use my S3 when I need GPS. Don't need the bluetooth either so the Venus quite fits my needs for a tablet.
hi to all, greetings from Bolivia!, I read all your posts about the Venus cpu, the ATM7029 i was excited about it but now i decided not to buy it, you have open my eyes xDD i want a tablet for playing video games, good looking and 7 or 8 inches. i understand the Rockchip RK3066 is the best for that at the moment, is that right ? if not what cpu and brand do you recomend? under the 200 $uS
Thank you sooo much and sorry for my poor english. my native language is spanish

To get thread back on topic I posted my answer over here:So what?
http://www.slatedroid.com/topic/56314-arm-chip-clock-speeds-temps/
oh, how can I buy a tablet without gaming experience? Quad-Core turn out to be Dual-Core with a useless GPU, it's so ridiculous tablet from Ainol.
the RK3066 is a nice chip, but depending on the tablet (elf ii & crystal) it gets hot really hot when playing gameshi to all, greetings from Bolivia!, I read all your posts about the Venus cpu, the ATM7029 i was excited about it but now i decided not to buy it, you have open my eyes xDD i want a tablet for playing video games, good looking and 7 or 8 inches. i understand the Rockchip RK3066 is the best for that at the moment, is that right ? if not what cpu and brand do you recomend? under the 200 $uS

so which kinda games are you going to play on it??
by the way I speak Spanish in case you want to PM me.
Ainol tablets don't have RK3066.
Ainol uses mostly 8726-MX chip for their dual core tablets. They do not use any RK3066 chips. Later,the RK3066 is a nice chip, but depending on the tablet (elf ii & crystal) it gets hot really hot when playing games
will exist a custom ROM for ATM7029?
I've just noticed that the official actions web page says ATM7029 it's 1.3, Ainol says 1.5 Ghz but maximum speed on my tablet is 1 Ghz http://www.actions-semi.com/en/productview.aspx?cat=98&id=108

Antutu has updated to new version 3.1.2 which will block more chinese chipset makers cheats. It's known that eaven Amlogic overclocks when it notices Antutu is run.
Once again Antutu is crashing in Actions ATM7029 Ainol Venus.... they cheat.
Eaven the startup page of Antutu says this tablet is cheat.

Amlogic does not "overclock". It basically switches to performance mode when certain benchmarks are detected. I don't consider this a real cheat as you can activate performance mode yourself any time. As I said elsewhere, even Windows does this - it automatically switches to the "high performance" energy profile whenever the "Windows Experience Index" (WinSAT) benchmark is run.It's known that eaven Amlogic overclocks when it notices Antutu is run.

And Antutu's new red warning message "your phone is fake" is just caused by wrong build.prop impersonation/fingerprint settings, as far as I know.
I thought I had my "soon to be purchased" tablet down to just a couple, but after reading this thread, I have to re-think everything.
Thanks a lot! Hmmm, that sounds sarcastic, but I mean it.

Go Samsung Exynos 4412/RK3188/RK3066 and you really can't go wrong at the moment with any of those. Don't get a retina display. At most, only get an 1920x1200 10.1" tablet and ONLY if it is using either the Exynos 4412 or RK3188. Otherwise you won't be happy by performance for gaming or 2D intensive applications. 1920x1200 is really pressing it.
My personal favorite as far as combination right now actually is.... drum-roll...
RK3188 + 9.4" 1280x800 screen and 2 Gb of Ram (I.E. NO COMPROMISE on Battery Life or Performance, still a nice compact package, and at 161 PPI the screen is still super-sharp). The Ramos W42 is a good similar Exynos 4412 option however beware it lacks HDMI out. I am using the PiPo M8 Pro. Loving it.
If you want something cheaper (and many of us do) you could pickup an 8" RK3066 powered device with a 1024x768 screen and at least a 4000 mAh battery (preferably don't get less than 5000 mAh)
You will have excellent performance, still have a 160 PPI so a good screen will look excellent, have a nice compact package but still much more usable than a 7" device and decent if not amazing battery life. Personally I like the Teclast P88HD (the RK3066 version) a lot because the build-quality is phenomenal.
That is my 2-cents. I have now "hands-on" tested an Action ATM-7029 chip device and while the Android Jelly Bean experience is surprisingly good, app compatibility is really poor and you can pretty much forget about gaming (i.e. playing anything beyond like... Temple Run) and will probably find yourself frustrated as common applications that work on other platforms won't work well on your device. My experience was NOOK magazine reading is broken.
When you can get an RK3066 for "similar" pricing, albeit a bit more... it just doesn't add up. Heck, you can still get AmLogic Dual-Core MX devices for practically free (once again, if you are looking at two devices and there is only a $10 - $20 difference I would tell you to just spring for the RK3066 as it is a significantly better chip vs the MX). I have never used an MX device but I am sure app compatibility is pretty decent and it uses the Mali-400 GPU which helps A LOT.

Regarding compatibility issues of the GC1000, developers are likely writing code to run well on the Mali 400 GPU that happens to be in their devices rather than programming to comply to the Open GL standard. On the issue of slow benchmark results, benchmarks optimized for Mali 400 devices may not fully utilize the performance modes of the GC 1000. I'm not convinced that Actions was somehow cheating on the Antutu benchmark, even though the GC1000 scored low on other benchmarks/games. It's possible that these other programs use libraries which favor the more familiar Mali 400 due to non-standard Open GL programming practices.
Actions are already cheating by selling their A5 CPU as "Cortex-A9 family". If Antutu attests the ATM7029 a CPU or GPU performance that it shouldn't have according to other benchmarks and real-world apps, then there's clearly something fishy going on...I'm not convinced that Actions was somehow cheating on the Antutu benchmark, even though the GC1000 scored low on other benchmarks/games.
ATM7029 is ARM Cortex A5 SoC, it's 99% becouse on the site of Actions there is

And Cortex A9 can have ONLY VFPv3, then Cortex A5 can have VFPv4, but in allmos all devices it hav VFPv3
