OMAP video decode.. - General Questions and Answers

Some weeks ago i was thinking in a Motorola Atrix to replace my old HTC Hero.
It's a good device but after some questions...

If you want to play H.264 high profile movie, DO NOT BUY Tegra2 based devices.
common 1080p(BDRips) are MKV(Container)+H.264 [email protected]~5.x+DTS/AC3 audio.
Tegra2 have hw limitations to play H.264 High profile.
My recommendations are
1. SGS2 : 1080p/1080i(it can de-interlace with HW)
2. Sensation(or Dualcore Snapdragon equipped devices) : 1080p capable but some shutter occur when you playing high bitrate movies.
3. Galaxy Tab(7inch) : can play 1080p
MKV container and DTS issues can be solved with Diceplayer.

My question now is:
How do OMAP 4430 'handles' MKV 1080p High Profile/high bitrate?
I've read that 'theoretically' OMAP should be better in 1080p decode that Samsung Exynos.. Is this truth?
Another question...:
Someone knows the difference between OMAP 4430 and Galaxy Nexus OMAP 4460 ?
Cpu i think it's the same.. probably its the mhz on PowerVR SGX540 right?
yes.. Droid Razr will be my next phone.
Thanks in advance.

Diceplayer does not support OMAP4 yet.
Samsung's video decoder implementation is much faster and powerful than TI's implementation. Samsung want to use Exynos to their TV and Settops. So Samsung AP's video decoder accept all of H.264 profile & level.
Exynos and Hummingbird support Zero copying rendering. it is much faster rendering than OMAP4's V4L2 overlay rendering.

Thanks for your help Juami..
That means that diceplayer dont run on android's with TI OMAP4?
Galaxy Nexus have a OMAP 4460.. i guess there will be support for OMAP in [a near] future right?
About OMAP4's V4L2 overlay rendering... is better then the rendering/decode engine on Dual Core snapdragons [HTC Sensation/ Sensation XE]?
Thanks

[Q] d2g processor?

hi everyone at these great XDA forums i have a quick question, what processor does the d2g have? ive seen several reports say that its a TI OMAP 3630 and other reports saying that its a 3640, and frankly i have no idea which it is.
On a similar note, whats the real difference between the 3630 and the 3040? ive read that the 3630 handles memory better than the 3640, i dont know if theres a way to tell, and i dont know if theres anything else that is different between the two processors.

TI OMAP3630-1200
from motodev website:http://developer.motorola.com/products/droid2global/
so whats the difference between the 3630 and 3640?

not sure exactly this is what the wiki has for them:
# OMAP3640 - 1 GHz ARM Cortex A8 + PowerVR SGX530 GPU + 430 MHz C64x+ DSP + ISP (Image Signal Processor)+IVA 2+ hardware accelerator
# OMAP3630 - 720 MHz ARM Cortex A8 + PowerVR SGX530 GPU + 430 MHz C64x+ DSP + ISP (Image Signal Processor)+IVA 2+ hardware accelerator
So it almost looks identical but the one used in the D2G is the 3630-1200 meaning it's stock clocked @ 1200Mhz (1.2Ghz) so I'm not sure what's ticking different on the inside.
thanks for the reply newk, i didnt think much was different
I was actually told the D2G has the same cpu as the DX and M2 and not the D2. The different actually being D2 doesn't have 720 video recording ability, unlike the DX and M2, which have it possibly because of the cpu.

I can tell you the D2G does not have the ability to record in 720p or for now. We can only record in 420p.
I would love to see someone modify the video camera app to allow us to use 720p but I also think we may be limited by the camera sensor.
Milestone 2, which essentially is Droid 2 hardware wise with a GSM radio can do 720P. CPU is weaker than the one on D2G (3630-1000 on the MS2 vs 3630-1200 on the D2G). Camera sensor is the same on both. 5MP sensor is more than enough resolution wise not only for 720p but even for 1080p. I guess we will see some hacks in the future regarding 720p recording on D2G. Give it some time. I won't be surprised even if Motorola makes it official with some of the next updates. But, honestly, 720p video on most phones today sucks enough not to be worth it anyways. Doubt MS2 (eventually D2G) will be any better.
i believe its the camera sensor itself that doesnt support 720p, being the same sensor as in the droid og and all

Qualcomm's Dual-core cpu inferior to others?

So I visited www.phonearena.com yesterday and saw the news about the HTC Pyramid.At first I thought wow,Qualcomm and HTC won't only get left behind but will have about the same technology and will run at higher frequencies.
But then I remembered something that troubled me.I remember reading somewhere that Qualcomm's dual-core CPUs will be based on the current-gen Cortex-A8 by ARM,while others,like Samsung's Orion,will be using the next-gen Cortex-A9 that is superior in both perfrormance and consumption,while being designed especially for dual-core CPUs,unlike the A8.
What's your take on this guys?
No one?

Strongly agree
i hope this isn't true. tegra 2 outperformed old cpu's with only one core running! that's because it's Cortex-A9. now, if it was Cortex-A8, i don't think there would be much of a difference.
In fact i think it is superior to the tegra 2 or Orion plat form despite being an cortex A8 architecture, but it is not a long term solution point proven as Qualcomm is developing it A9 counterpart the MSM 89xx
How it is superior? Well between A8 and A9 architecture to my knowledge there isn't much of a difference, the major one is enhanced soc and the capability to use DDR3 ram instead of being limited to ddr2
But how these two doesn't matter in the short term, well the first one is obvious because Qualcomm doesn't use just a Normal Cortex A8 architecture ( was used on the first gen of snapdragon) as the second generation MSM8255 used on the desire HD for exemple has an enhanced soc and cach point proven when compared to a lets say Omap 3 or hummingbird in every cpu benchmark i believe the MSM comes on top(correct me if i m wrong).
The second point which is about Ram, i don't believe we will be seeing DDR3 ram on smartphone anytime soon so at this it is a kinda useless advantage.
Now add to that if the rumors are correct that one cpu can be switched off if the charge is low then while the on tegra 2 which use a dual core architecture and not a dual cpu architecture.
Edit: this is true + Asynchronis clocking for each core!
Also in terms of graphics, the MSM8x60 comes with adreno 220 which is definitly faster than the adreno 205 almost as fast as the SGX540 and which is rumored to be faster than the GPU in tegra 2, the geforce, as for the Orion is believed to get the SGX543mp2 but Orion is not coming anytime soon, and probably will hit the market once tegra3 and MSM89XX is almost there (which comes with Adreno 300)
Hopefully this does help you, i know that not everything i mentioned is accurate, but i ll invite you to watch this

Synthetic benchmarks like that though don't gauge real life performance though.

I do agree with you, but they do give a scal for the performance especially when there are different types that relies on a different system to test the perfomance.
In real world you have to agree that MSM8255 is the fastest CPU out there atm just look at how the Desire HD is a screamer! or even the G2/Desire Z with the same CPU but clocked 800mhz does a pretty great job even compared to the latest omap3/hummingbird phones.
Definitely, the MSM8255 45nm matches the old MSM8250 65nm even when the stock clock in the Z/G2 is only 800 mhz, versus that extra 200 mhz. The gpu is lacking compared to others.

No,the GPU of the Desire Z/HD only lacks against the SGX540 of the Galaxy S!

As lotis said the only GPU that is faster than the Adreno 205 is the SGX540 and by a very slight marging in 3D while the Adreno wins in terms of 2D. The thing with Adreno GPUs is that they are clocked with the CPU and i believe the comparaisons were done with a G2 vs SGS + lagfix and froyo , i believe the GPU on the Desire HD does have a higher clock than the one on the G2 and thus perform better but again is this a fact or just another rumor if someone could confirm this..
But for a fact we all know that a stock G2 on pure android does 1600-1800 Quadrant score and a pure desire HD does a 1900-2100 on Android + sense out of the box

i m looking forward to the pyramid hopefully HTC will show it on the MWC (but im afraid there is a chance that they won't because they've just released the desire HD counter part in the US aka thunderbolt and inspire 4G) or else i might be tempted by the Motorola Atrix
whats up with all the fear and worries ? quandrant for tegra2 is a mere 1911 . it will get its a** kicked by anthing qcom makes in 2011 .
that said , there is a low possibility quandrant only runs single core enabled on quadrant , but what makes u sure that other apps will run dual core then ?

Nothing!That's the thing!
At the moment there is no software that takes advantage of both cores.I think that Gingerbread also has problems.So we have yet to see the performance gains by dual-cores.

I didn't think it was possible for an A8 to be dual core
The dual core cortex a8 qualcomm is building is a heavily customized version. It has features from a9 built into the cpu.

My laptop already is for surfing the net only because I prefer the large keyboard(it's a 17 incher after all ).Everything else I do with my smartphone,which has a 25% share of my gaming time.I also have a ps3!
Now,quad-core CPUs will first be for tablets(August 2011) and then for smartphones(Fall 2011?Maybe).These will pack some things like 12-core GPUs etc.Tests have already shown that they beat many dual-core x86 CPUs.What's next?Dunno,but I surely wanna see!
The next computers is possible, but relatively weak computers per say. But can any of our phones run crysis or crysis 2? Are they even remotely capable of generating over 10fps of it? Even the MALI 400MP, Tegra 2, adreno 220 or power vr SGX543 can't manage that. I don't think we'll be seeing any SoC's with that sort of power until maybe two years?
Point being, phones will never hold the same amount of power a computer can output. So computers will stay. Who's to say computer SoC's haven't been improving? sandybridge, quantum processing, six cores core i9, 48 cores? No one cares for computer news anymore?
Anyways onto the topic, looking at the new gpu benchmarks posted of the dual core snapdragon, 1.5ghz. They're making the other cpu's look bad. So maybe the SoC isn't that bad after all. looks like it was a prototype also so the finished product could be even better. Source:

texas instruments omap 4470 and MKV videos

So i know the tegra 3 processors can handle 720p mkv files with ease, so i was wondering how does the texas instruments omap 4470 handle them? I heard this new processor in the BN Nook HD+ is supposed to be faster
thank you for moving it!
I am going from a nexus 7 to a nook HD+ and i heard the 4470 is on par or faster with the Tegra 3. I just want to make sure i can run my 720p mkv videos after i root it
thanks!

Adreno 225 at 720p and mali400?

Hey guys was hoping you could help me out since I am a big newbie when it comes to the mobile world
I am looking to buy a new phone, and one of the phones I've choosen to buy has adreno 225, 1.5ghz krait and 720p 4.7" screen (its the pantech (or SKY) a830l ).
Was hoping you guys could help me and let me know which games and/or apps (if any) I wont be able to run because of gpu bottle-neck on this resolution, and how future proof the adreno 225 will prove to be..
additionally, my alternative choice is htc One X
One X is almost twice the price of the pantechm , so I want to know whether its really worth it in terms of cpu and gpu power (ignoring the better screen for a bit).
Also, I've noticed that many 'very' powerful cell phones have mali400 (including galaxy note (1) and SIII). I've heard people say that adreno 225 is better than mali400 AND that SIII outperforms in games cell phones with much more powerful graphics card. So now im really confused. Am I missing something?

mali 400 easily outperforms adreno 225... that's why it is in galaxy s3
and it has capability upto 4 cores so it is better
more comparable to it would be adreno 320!
the "pantech" one is a good choice if pricing suits you! You'll be able to play many games but i assume 1.5 ghz krait is either dual/quad core!! If yes you are good to go!

thanks for the reply, really appreciate the clarification.
Ive seen a couple of benchmarks but benchmarks are just benchmarks. Based on current games an apps, how many games and apps are there that wont be able to run because of the gpu? and can you give me some examples? hope I'm not asking too much :angel:
the pantech 830 is Super IPS LCD 720p (4.8"), krait dual core 1.5ghz and adreno 225
Samsung galaxy Note (N7000) is Super Amoled 720p (5.3"), cortex A-9, mali400, about 25% more expensive than the pantech
HTC One X is about twice the price of the pantech (and I really doubt I need the quad core)

Well the pantech phone will run almost all games.. Games which have state of the art graphics like nova3,wild blood and latest nfs, asphalt releases might be a problem.. But those can also be made working by rooting and enabling hardware acceleration
Note and one x will run all games but i understand they are costly
Then again it comes to u, how much u want to pay!

thanks for the reply..Im willing to spend more but I just dont want spend money on hardware which I wont be utilizing. Id like to game on my mobile, but not dying do and dont mind if a few games dont work. Prefer gaming on my PC in any case.
Just want to confirm that all apps would work and I could run 720p videos on the pantech smoothly.
