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.

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 hope you're right!!

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:

Adreo 220 vs Mali-400..which one is faster and more powerful ??

guys..which one is faster and more powerful..Mali-400 or Adreno220 ??
my sensation running Android Revolution HD.. CPU overclocked to 1.5GHz and GPU overclocked..
i can't get scores like GS2 (stockROM) or better than him !!

If I'm not mistaken, the Areno 220 can push 1080p stereoscopic 3D.
The question is whether the manufacturers wrote drivers to help with the hardware acceleration, which is what Samsung did with the Exynos-Mali400. =)

This site is also very informative http://www.droidgamers.com/index.ph...1661-dual-core-beasts-the-decision-to-buy-one

Mali-400 MP4 is better.

i have htc Sensation and i think Mali-400 is more powerful and faster
i installed Fruit Ninja HD Crazy (modded version to get alot from fruit in arcade mod) so in htc Sensation even with overclock i get lag..in SGS2 without custom rom it's so smooth
in quadrant i use advanced edition in 2D always i get like 330 and 3D i get from 600 to 1000 with overclock..in SGS2 without anything in 2D get 800 and 3D 1200 !!!

OMAP video decode..

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] Difference between 800Mhz Cortex-A5 and 800Mhz ARMv6

Hello,
I already have a Samsung Galaxy Pro with a 800 Mhz Cortex A5 processor and I was looking up the Sony Xperia tipo and found that it has a 800 MHz ARMv6 I want to know what is the difference between the two processors.
Thanks.

Thanks bbrad! I was just about to ask the same question!!

What? All the new phones are armv7,
And the majority of older and cheaper phones are armv6. Its a completely different thing from cortex. Cortex a8 is what's in the sensation and gs2, cortex a9 or a hybrid of it is in the gs3 and all the current generation phones, and cortex a15 is not in any phones yet but there are partially a15 based phones. Each generation is said by arm to be twice as fast and efficient than the last. Anything armv6 is probably old and won't be able to run as well as an armv7 device. However while they are related armv6 is not the same as cortex a6.

The ARM Cortex-A5 is ARMv7 and is newer and better than the ARMv6
The Samsung Galaxy Pro with ARM Cortex A5 has a faster graphics output and memory bus so will performe better than the Sony Xperia tipo ARM11-ARMv6
so Samsung Galaxy Pro has the better processor
http://en.wikipedia.org/wiki/List_of_ARM_microprocessor_cores
The ARM Cortex A5 ARMv7 is intended to replace the ARM11-ARMv6 for use in devices. Compared to the ARMv6, the Cortex-A5 offers the advanced features of the ARM v7 architecture over ARM11-ARMv6 architectures e.g VFPv4 and NEON advanced SIMD. It also allows devices to run current software

Overlocking GPU??

recently i came across overlocking GPU.. in sense4a built by derefas made GPU overlocked to 220 n he mensioned that its safe.. is i dont think it wont create any problem.. some problem ll exist.. can anybody know that problem?? and overlocking to 220 means now we have adreno220 ?? is it like dat?? n i google it but i saw that for adreno220 it clock speed would be 1.2Ghz to 1.5GHz(acc. to this site - http://en.wikipedia.org/wiki/Imageon). so that rom has gpu overlocked n cpu optional, it means iguess it make some problem.. can anybody explain me pros n cons..:fingers-crossed:

No, it ain't like that. The chip is embedded, and can't change.
Our Chipset is MSM7225A (according to http://pdadb.net/index.php?m=specs&id=3073&c=htc_explorer_htc_pico) and the GPU supported is Adreno 200 (enhanced) according to (http://en.wikipedia.org/wiki/Snapdragon_(system_on_chip)).
The Adreno 200 was said to support the following in the wikipedia site.
Adreno 200 (AMD Z430) inside the QSD8x50 (1 GHz) and MSM7x27 (600 MHz A11+L2 cache). It offers a programmable function pipeline and streaming textures with support for OpenGL ES 2.0, OpenGL ES 1.1, OpenVG 1.1, EGL 1.4, Direct3D Mobile, SVGT 1.2 and DirectDraw. (22M triangles/second, 133M pixels/second, clock speed up to 128 MHz).
Click to expand...
Click to collapse
Even some googling didn't help in finding the clocking speed of our GPU. According to wikipedia, it supports 128 MHz.
Note that it was for the devices QSD8x50 (1 GHz) and MSM7x27.
But, an enhanced GPU is supported in our Chip. So, I got the following info from the Qualcomm website.
Adreno™ 200 is the first OGLES 2.0 GPU with unified shader architecture and makes maximum use of the graphics processing power of the GPU. This GPU is a leap forward in visual graphics quality from OpenGL-Es 1.x, which enables developers to implement effects that were previously a daunting task. APIs supported include OpenGL ES 2.0, OpenGL ES 1.1, OpenVG 1.1, EGL 1.3, Direct3D Mobile, SVGT 1.2 and DirectDraw. The Adreno 200 delivers streaming textures to combine Video, Camera, SVG and other image surfaces with 3D graphics. It also enables concurrent CPU, DSP, Graphics, and MDP and includes a programmable function graphics pipeline.

And, so, I summarized that an enhanced GPU, in our chip, has a normal clocking speed of around 200 MHz, and it can be overclocked. How this is done, and all the other stuff, the developers might help you. And, if its safe... I also read that overclocking a little wouldn't harm. So, I guess it's safe.
Anyways, the Pros are that you would get a little extra fps, so you could "expect" a little improvement in gaming and video playback.
The Cons... Well, anyone using an overclocked GPU for long might know.

When overclocked the textures are rendered little quicker than normal clocking. It won't double the frame rate as some guy doubted. Look at the details of our CPU and gpu.
