[Q] Allwinner a10 vs cortex a9

Hello everyone
I want to buy a budget tablet and of so much research i have found two tablets in my budget
1. Ainol novo 7 tornados
2. Ainol novo 7 advanced 2
The screen size, processor and most of the hardware are same and both run ics. The only difference is that Advanced 2 has a allwinner a10 processor and tornados has amlogic. The allwinner is based on cortex a8 while the amlogic is based on cortex a9. The following site compares them but i am confused that if a8 is better than what is the use of a9. Isnt the cortex a9 successor of cortex a8
Actually i cant post link because of restriction so do a google search for allwinner vs amlogic and click the link of "slate 4 sure blog"
Please recommend me that which one should i buy and is the comparison true.(i.e A8>A9)

Hey...check this website out. i don't know why XDA developers haven't dug into everything Ainol since they're cheap and powerhouses. i would suggest you ask there but in my experience the a9 is a successor and it's much faster. here's the lnk http://www.slatedroid.com/forum/341-ainol-amlogic-cpu-devices/ and there you have all the devices. unfortunately the Advanced 2 is in the upper thread since it's a bit older! I got my Tornados for only 71 USD off of ebay and it regularly ranges to 100 USD...so if you gotta spend the extra couple of bucks for newer software ..then why not...if i helped press the Gracias ( thank you) button

if I could relight this one briefly so I don't create a new thread: can one of you more knowledgeable guys explain to me: for a single core Cortex-A9 implementation like an AW or the AGPtek / WM8850 unit, does it matter much how generous internal memory is? 512mb sounds like enough for such simple design but I do not yet understand how the memory controller manages memory especially to feed the graphics processing unit. for the little cost, i'm prone to want to go "more is better" route: 1GB of internal...

Are both tablets with the same AP? If not then more may not necessarily be better. Let me explain - if one of them has a dual channel memory controller, pick that even if it has lower memory. The reason is that in case of dual channel memory controller the arbitration overhead is lower so memory fetch latency is lower for all components.
If they both have a single channel memory controller, pick the one with the 1GB RAM. Hopefully answers your questions.
As far as how the memory feeds the GPU - usually it is the other way round. It is the GPU that fetches the data from memory. The implementation is very different from GPU to GPU and therefore from AP to AP.

Allwinner has bigger community and 1GB is better!

JXD S7300 (Just a friendly FYI)

This is a 7 inch gaming tab with built in game pad. It comes pre-rooted with Android 4.1.1 a Dual-Core Amlogic MX Cortex A9 @1.5GHz, a Quad-Core Mali400 MP GPU, and 1024MB DDR3
Set to launch sometime in 2013.
They have current models out that are single-core 1GHz, Quad-Core Mali400, and 512MB DDR3.
JXD S7300

looking forward
Very exciting. I've been looking for a gaming tablet and there are a few on the way that look great. The archos is my favorite so far.
On the JXD, are those specs accurate? I'd say it would have a price advantage, if so. That brand is usually very affordable.

[Q] Mira 2 Tablet rom

Heelo
i have a LC-Power Mira 2 10 Inch Tablet and i search for some better rom for it.
Computer type Tablet Computer - Tyon Series
Operating system Android 4.0
CPU 1,2 GHz A10 - ARM Cortex A8
GPU Mali 400MP
RAM 1GB DDR3
Memory 8GB NAND-Flash
Dimensions display 26,65 cm / 10,1"
Resoultion display 1024 x 600 pixel
its an ARM Cortex A8 Prozessor is there an identically constructed Tablet which rom i can use ?
i searched a lot but dit not find anything right.
has anyone an idea ?
thx
tmelord

I also bought Mira-2 last christmas and now that I have gotten to know the thing a little bit I would like root it. Now I have read much of guides on how to make custom roms, but all the articles make whole ordeal seen a little bit overwhelming. I'm not just asking anybody to do the work for me, but some advice would be much appreciated.

[Q] Tegra 3 GPU ULP GeForce Question

Hello,
I have a question that I've been scouring the internet for ages for but have never found the answer,
I own a Nexus 7 and a cheap Tablet that utilizes the Mali 400-MP.
In my expirences with general gaming (and benchmarks) the Mali 400 outperforms the tegra by a long shot.
My question is why this is the case, I checked the specs of both chips and the tegra has 12 cores vs the Malis 4 cores, the Tegra even has a higher clock rate so I just can't understand why the Tegra is less powerfull.
Is it just that the games I play are optimized for the Mali better than the tegra?
My thanks to anyone who can shed some light on this

chip are different as Pentium dual @3Ghz = core 2 duo @1.6Ghz
Both have 2 core, but since the first is netburst an the second core architecture they don't have the same way to calculate, manage tread etc etc

Thanks

Wow that was fast! thanks for responding so quickly,
im still a little unsure, the Tegra 3 uses the ARM Architecture and so does the Mali so i don't think its that simple, i could be wrong i guess...
if it is just for that reason, how would you go about comparing the two to find out which is better when looking at the specs?
Edit: ive just checked, they both use The ARM v7 Instruction Set, and i think they are both variations of the ARM Cortex-A9 chip,
plus what im looking for is more a comparison of the GPU where as i think Architectures are more to do with CPU's.

SIMD's and MAD's
I've been scouring the internet and came across the fact that the Mali 400 has more SIMD Units.
Could this be why the Mali is better? I must admit that I'm not really sure what a Single Instruction Multiple Data unit does performance wise.

Bump.
Recap: my question is why a GPU with more cores and a higher clock speed has less GFLOPS than a GPU with less cores and a lower clock speed

[Q] Android: Exynos 5250 (A15 dual core) vs Rk3188 (A9 quad core)

I was going to buy a tablet for uni, and as i have some experience with computers i decided to compare the tablets and buy which was best for me, however i realized I'm a complete greenhorn in terms of phone/tablet hardware.
I found that these two processor was the ones i had to pick from:
Samsung Exynos 5250 - A15 Dual core @ 2 Ghz
Has an excellent GPU T-604
Rockwell Rk3188 - A9 Quad core @ 1.8 GHz
Has an decent GPU Mali 400
I know that the Exynos has a MUCH better GPU and has the newer A15 architecture, clocked at higher speed but is a dual core.
But the Rockwell is a quad core but has a older A9 architure and has the worse GPU.
I tried to search for a comparison but came nil because I was comparing between different release date/architecture.
Could you guys people explain to this newbie the advantages and disadvantages of each processor, and which one i should pick?
Which Processor is better? why is it better? Better by how much?
Which processor would be better at Nds emulation? I know android nds emulator support multicore and GPU support
Rk3188 (quad core) vs exynos (better GPU, architechture)
Which one has the lower battery consumption?
Thank you for your time.

at first is it Rockchip RK3188 , not Rockwell .. 2nd, A15 is faster than A9 even A9 is in A9 quad core state, for better compatibility support for apps and games .. take exynos chip but the price is hinger than rockchip RK3188 tablet... battery comsumption are vary depnds actual MAH on the tablet + how the user usage on it's tablet + version ROM that perform

Tablet is not only about processor, build quality, screen, speakers - its a package.
As you did not mention exact models under comparison, it depends on what you look for and budget.
For price/quality top score, you can't go wrong with one of Cube u9GTV (quad) tablets :
Retina, aluminum body, IPS, HDMI, stereo speakers and 9+ hours of battery.
I have one myself, and I used the dual core (old model) for a year, so I know they last well and are robust.
One of issues to consider is that having ADB over USB to Cube tablets is sometimes a mess, so I'm using ADB over IP to debug things, which might be not the best solution for a developer.
Best luck with your choice!
