This is a hardware question, I have a friend who owns a Desire HD, now he goes on and on about how Single core phones are just as powerful as Dual core phones because, and this is his theory, a Dual core phone that says it is clocked at 1 GHz actually has either core clocked at 500 MHz, whereas the core in a Single core phone is clocked at 1 Ghz flat.
This just honestly seems like a frankly rubbish argument that doesn't make much sense to me, however I want to know if he's right, is there any literature out there that proves either way. Is he right? Or is he just being a boner?

long story short, he is wrong. keep in mind dual core s different from dual processor. the processor of a dual core simply allows 2 instructions to be carried out at onece adding performance to programs that have lots going on at the same time, but is still the same otherwise. They seriously help with multitasking so on android they would really help .

Correct! It allows 2 different "threads" to be computed at the same time. Your friend isn't all wrong though. Any app has to fully support dual threading. If it doesn't you will see the same performance from a 1ghz dual core phone and a 1ghz single core. Also remember the architecture of the CPU is important. In many cases a 1ghz phone may perform better than a 1.2ghz phone.

Well, almost.
Dual core means there are two independent processing units on the same chip. The chip itself operates at 1gigahertz, and that generally applies to anything on that die.
so your friend is wrong, as both cores run at 1 gig, but a lot more factors relate to actual performance.
In most cases, single core will not perform as well as a dual core at the same speed. (assuming they are the same arch)

Some dishonest Chinese sellers will do things like this.
Some places you'll see dual core NEC EV2 based tablets as "1ghz" even though it's two ~500mhz cores.
Other places you'll see a single core device deceitfully advertised as "dual core" as it includes a GPU in addition to the CPU.
They'll then add the GPU and CPU frequencies together and sell a 1.1ghz device as 1.5ghz.
(And don't get me started about seeing "Cortex A10" in the specs)
So long as we're discussing legitimate specifications, your friend is wrong
The most important thing is.... To tell your friend he is totally true.. When he revises his theory somedays later, then listen to him.

It really depends on the apps that you are running. Gingerbread does not fully support dual core processors but the Android (linux) kernel does. So if the apps you are running are written to take advantage of the extra core, they will run faster on a dual core phone. Where it does help to have an extra core is multitasking, with a dual core phone you will be able to smoothly run more apps at one time. But if you benchmark an app that only utilizes one core on both a single core and a dual core phone, the results will not automatically favor the dual core phone.

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?
Sent from my Desire HD using XDA App
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

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

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.

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:

I read something in the internet that says Infuse processor is the same as the Captivate.
Samsung just overclocked it so they can still use the Captivate's Hummingbird 1ghz processor instead of throwing it out on the recycle bin? I just can't find the link again and will try to find it and update the link here.
Anyone can confirm?

Sent from my SAMSUNG-SGH-I997 using XDA Premium App
from what I have seen samaung may have intended for this chip to run at 1.2 in the first place. I believe it is even the same part number.
it is very common for a manufacturer to release identical processors with a variety of clock speeds, cache ram, active cores, and other features. turning off features and releasing the chip as a lower model is a way to increase production. eg I have a 3 core processor in my pc but in bios I have overclocking options, when selected my chip becomes a quad core. this is because the processor is actually a quad core that the default settings turn off one core, my chip may have had one core that was sub par or it may be
perfectly good and been marketed as 3 core to fill in the demand for a cheaper processor.
this has been done with clock speeds and other features as well. and the snapdragons chips have 1.3 and 1.4 ghz versions but despite a differrnt part# are the same core. they have potential to go up to 1.7ghz or more. a few hummingbirds have potencial for 1.4-1.6.
Hi,
i recently return my samsung (4th time) galaxy s2 becouse of various defects , i been looking at the sensation however i have a few questions , firstly for all its issues i like how fast and responsive the galaxay was however when i tryed the sensation i noticed its not as smooth as the galaxy or that much smoother then the desire hd.
One possible reason for this i noticed was that the sensation uses a asmp cpu , which seems a bit cheeky to me. I mean im buying a dual core phone so i would like both cores to work at the same time as opposed to one working then the second kicking in when the first is loaded. From what ive read ics should have better support for this setup , so i was curious does anyone think we will see that much of a difference bearing in mind the sensation is asmp.
I notice there`s a lot of talented devs from the desire development and hd which is encouraging so i was hoping to learn from various users how much of a performance increase there seeing in custom roms ie is the browser jerky like stock ??
Appreciate any / all feedback thank you
I'm interested in some more more info on this topic as well.....
Sent from my Sensation using xda premium
Read up!
ok so aSMP doesn't really work in the method of core 0 gets loaded then core 1 kicks in, thats way off.
basically SMP cpus like Tegra and Samsung's both cores run at the same speed, so core 1 follows core 0. This doesn't mean that core 1 is actually processing anything. In most cases due to gingerbread the phone is still mainly running on one core unless the app supports multicore.
aSMP allows the cores to run completely independent. This is great for battery life. Core 0 can do things like play games and stuff at full speed while core 1 handles background data.
so playing angry birds while syncing photos on flickr:
core 0 could be running at full 1.5Ghz
core 1 could be running at 500Mhz just do handle the syncing
This is basically the idea. We will get better support with ICS for full and proper support for multiple cores and the kernels will only get better as devs learn.

As i say thou im not expert i can appreciate theres other factor to take into account such as kernal etc, im just going with hands on usage and trying to evaluate the future potential for both devices before making a decision to which i should choose

The sensation's CPU works in a much more power efficient way, while still offering the speed of any other dual core CPU. It allows different clock speeds for different cores so applications using only a single core will be able to clock it differently to those using the other in the background. Computers, especially laptops work in a similar way, as there is a need for power efficiency. Realistically the Galaxy SII runs smoother due to it running a much less resource hungry skin on top of android, but both the CPU of the sensation and the Galaxy SII are both of a similar calibre, so it is very difficult to say which is better.
again thanks for the reply , defintly understand how this asmp buisness works more now which has given me some stuff to think about

Neither architecture, SMP or aSMP, will commit both cores to one task unless the app is multithreaded and it currently needs the use of both cores. This is the same way that multicore pc's operate. That's why when quad core CPU's first came out people said that they didn't feel any faster than comparable dual core chips - most existing apps at that time were written for single or dual threaded use so the third and fourth cores largely sat unused. The pc doesn't just force the use of the extra cores just because they are there (regardless of how they scale, aSMP or SMP).

Also the new firmware has made it smoother due to extra optimisations. Web browser is not as good as the galaxy S 2 due that being GPU accelerated. Power wise the Sensation you will get somewhat more out of your battery life wise.

If you look at my thread and see the post:
MSM8x60:
Adreno 220 GPU
2x Cortex A8 Based Cores
512KB L2 Cache
45nm
upto 333Mhz LPDDR2
Exynos 4210:
Mali 400 GPU
2x Cortex A9 Based Cores
1MB L2 Cache
45nm
support for LPDDR2/DDR3
Tegra 2:
ULP Geforce GPU
2x Cortex A9 Based Cores
1MB L2 Cache
40nm
support for 600Mhz LPDDR2
So the biggest thing is is that the Exynos is based on a new core micro-arch then the Snapdragon 2, also it has the ability to support DDR3 memory. To go into more detail about ARM Cortex.
Items that A8 and A9 have in common:
Jazelle RCT for JIT Compilation
Neon SIMD Instruction Set (Optional)
Thumb2 Instruction set
VFPv3 Floating Point Unit (Optional)
Cortex A8:
Superscalar Dual-Issue Micro-Arch
2.0 DMIPS/Mhz
Cortex A9:
Out-Of-Order Superscalar Micro-Arch
2.5 DMIPS/Mhz
Jazelle DBX for Java Execution
Dual-Core Processing Built In
The SGSII has a new generation architecture as so does the Tegra
This thread is iteresting. I want to continue that.
my cpu0 and cpu1 arrive at 1,7 ghz. so cpu1 doesnt arrive up to 500 mhz
Are there really that many things out there that can take advantage of a dual-core cpu? It seems to me that a decent cpu/gpu can go really far, but idk.
I'd imagine it'd be similar to a desktop. It will initially help with general smoothness of the user experience. Eventually apps will catch up with the hardware and be multithreaded.

More cores = better efficiency = longer battery life. It's not all about performance.
On any os aside from android, no.
Currently no. Seeing as software has yet to catch up to hardware, and really never has in this technological era. >.>
So with such info, one can make the statement to say the latest hardware is never needed, atleast in its time. Sooo... lets all throw away our core i7's, 1080p displays, Radeon HD 6990, and go back to the good ol' pentium 4 with integrated Intel graphics.
the new android os (ice cream sandwich) is supposed to support dual-core processors. If this does end up happening, it won't be long till there are apps such that do make use of the dual-core as well.

Dual core most people will tell you quadcore is faster than dual core this is false. Just because you have two more of something doesn't mean anything if you can not use it properly. This is why tegra 3 as you see gets beat by Qualcomm krait (dual core) and Ti omap 5 (dual core). Its not about how many cores its about efficiency. Nvidia pretty much doesn't know what they are doing still in the phone market.
Quad core on a phone is not required imo.
I would stick with a dual core (My Galaxy SII has never given me any trouble) - quad core is pricy and no real need for it at present. But you can always do a future investment since you will eventually want a quad core.
I am personally waiting till my quad core phones drop in price and are required.

The thing is, the HTC One X in the UK can be brought for £28.50 a month - I would have to pay more than that for the Galaxy Nexus. Quad core phones are no more expensive to buy than dual core - phone manufacturers realise that at present, they simply don't have a market for constant £41 on free prices.
For the people who say quad core means less battery are wrong. Nvidia is still using
A9 architecture and 40 mn. Ti omap5, exynos (5, something), Krait, all beat tegra 3 quad core technology. Ti omap 5 and krait are using 28mn and exynos supposedly using 32mn. All of these processors are a15 which pretty much destroys nvidia a9 architecture. They also use less power voltage and completing the same task. Compared to tegra 3.
Quad core is pointless if you don't have the battery to back it up. The Razr Maxx has a 3,300mAh battery. That should have been available a long time ago. Companies keep designing phones with bigger screens, more powerful processors, and energy-draining 4G LTE. This is all fun and well, but the battery is the most important part and need to be worked on more.
In some cases dual core processors can actually be faster than processors with quad core.
