"Intel Bulverde 520 MHz"
The one in the Universal
OR
"Qualcomm MSM7201A 528 Mhz"
in the new HTC HD unit
I feel they are the same. Am I right?
qualcomm is much better
Its similar the difference between a 2.5ghz Pentium 4 and a 2.5ghz Core2Solo
i don't think that core2solo and pentium4 with ht much differ

Google up "Instructions per second" and you'll understand.
The Netburst architec of P4 is one of the worst example in history of it. A failure by engineering standard.
The PXA270 Processor in the Universal actually runs at 624mhz and is underclocked. The HTC X7500 uses the same CPU running at 624mhz. It is clearly the better CPU.

Very, very wrong.
I wouldn't say that the Intel two processors are exactly the same, with one just being underclocked via software. Notice how intel puts out multiple pentiums of a given generation at different speeds? Would you venture to say that all those chips are the same too?
Also, clock speed is a poor metric when comparing chips from different companies. PDADB.Net says that the Intel chip has a ARMv5TE instruction set and the Qualcom chip has a ARMv6 instruction set. The Intel is a generation behind.
Comparing
Wikipedia says
Main article: Megahertz myth
The clock rate of a computer is only useful for providing comparisons between computer chips in the same processor family. An IBM PC with an Intel 486 CPU running at 50 MHz will be about twice as fast as one with the same CPU, memory and display running at 25 MHz, while the same will not be true for MIPS R4000 running at the same clock rate as the two are different processors with different functionality. Furthermore, there are many other factors to consider when comparing the speeds of entire computers, like the clock rate of the computer's front side bus (FSB), the clock rate of the RAM, the width in bits of the CPU's bus and the amount of Level 1, Level 2 and Level 3 cache.
Clock rates should not be used when comparing different computers or different processor families. Rather, some software benchmark should be used. Clock rates can be very misleading since the amount of work different computer chips can do in one cycle varies. For example, RISC CPUs tend to have simpler instructions than CISC CPUs (but higher clock rates), and superscalar processors can execute more than one instruction per cycle (on average), yet it is not uncommon for them to do "less" in a clock cycle. In addition, subscalar CPUs or use of parallelism can also affect the quality of the computer regardless of clock rate.

Sonus you are correct about the Mhz comparison. However, the PXA270 in the Universal can be safely "overclocked" to 624Mhz because the chip is designed to max out at that speed.
I would still like to see some benchmark tests between the 624Mhz PXA270, and the 528Mhz Qualcomm MSM7201A.
Generations aside, I can't see the Qualcomm chip outperforming the Intel Chip by much, if any. Also, it should be noted that the PXA270 can be scaled, not sure if that is true for the MSM7201A.
The other catch phrase is "Performance per watt". I bet the MSM7201A has a huge advantage over PXA27x in that, mainly due to newer manufacturing process.
That may be true wuzy, but considering the PXA270 is almost 5 years old and still being used in new devices should tell you plenty about its capabilities and performance.
Not really... It does, however tell a lot about the stinginess of device manufacturers.
As for the overclocking, not every Universal can run 624 MHz without crashing because the CPUs are going through a selection process after manufacturing and there is simply no reason to use the best ones for a device that doesn't need them running at full speed.
The crashes are usually the result of the type of program used to overclock and also the rom. For the most part, people have found that 624mhz is pretty stable, inlcuding myself. Some have even pushed it beyond that speed, but that's another story...
Also take this into consideration:
The Universal has been on the market since 2005, almost 4 years now. By industry standards, it should be obsolete. Why is it not then? Simply, it is quite inexpensive compared to the newer devices having similar features, sometimes less. When it comes to performance vs. price vs. features, you just cannot beat the value of the Universal and its blistering fast 520/624mhz PXA270 CPU! The PXA270's performance is only rivaled by its bigger brother, the 800Mhz PXA320 which has made its way into some newer devices already.

Try out a Diamond/Touch Pro with Opera9.5 the next time you see one and notice the speed difference.
On MSM7201A compared to our PXA27x it's a lot more smoother.
The lack of driver for MSM7200 on a lot of devices released last year tainted our perception on the new generation chips I think.
Touch HD vs. ASUS Galaxy7 at end of the year... hmmm
I think you're missing the point wuzy.
I know there are newer devices out now that can deliver slightly better performance in some areas than the Universal, but considering how old our device is, it is to be expected. All I'm saying is that given the age of the Universal compared to what's out there now, The Universal has held up well. Furthermore, with all the new cooked roms popping up, you can expect the Uni to live even longer!
Take a look at H.264 decompression and real high performance tasks and the PXA270 looses so badly against the PXA320 that it is not even funny anymore...
Why does the Uni keep up with most software? Because most programs are written for the old ARMv4 instruction set, thus wasting a lot of CPU cycles on newer processors that have already moved on. Apart from that the average application simply does not need that much CPU power to begin with.
The Uni held out well in a market that is very slow to adapt new technologies to begin with. The Axim x50v had a dedicated graphics chip at the end of 2004 - how many applications make use of that today? Only some games (ports, emulators) and media players. For those alone the Axim has held out better than the Uni though as it is still one of the best performing PPCs on the market.
Our little one will be around for quite a while, but it is far, far away from what nowadays devices can offer and it shows if you run anything beyond mail and office apps on it.
Which Processor is faster & better
I feel from your input above that "Qualcomm MSM7201A 528 Mhz" has higher performance, clock rete, Instructions per second, & Performance per watt when compared to the "Intel Bulverde 520 MHz" about 2:1 am I right ?
Another Question:
What is the highest speed Processor available for the PDA industry today?
Best Regards.
IMHO the ARM Cortex processors are very far up the ladder when it comes to performance and energy consumption. The Pandora makers claim 10 hours of runtime for their device. Together with its media chip this little bugger is capable of decoding 720p HD video streams (take a look at the Archos 5)
I am not sure if the MSM7201A chipset's CPU alone reaches twice the performance of the Uni, but you will see a huge difference in apps that support and need the latest in CPU architecture (media players & games). If (one way or the other) the 3D capabilities can be put to use you will probably see more than a 2:1 performance boost.
The sad truth is the Universal is one of the slowest VGA devices around. Especially considering lack of the graphical accelerator (which was even present in prototypes).
Too bad the dedicated 3D chip didn't make it into the final design. But it's still better than having a 3D accelerator without drivers! I have a Sharp EM-ONE here with a GoForce 5500 that could theoretically accelerate many video formats. The sad truth is that because there are no drivers no media player can make use of the chip. Even worse: Because the graphics chip still controls the display video is even slower because the optimized X-Scale drivers can't be used. It's like Sharp and NVidia wanted to punish users double So, as bad as it is, the Uni is not the worst device out there!
x86
I wonder why there´re no x86 cpu´s placed in mobile devices yet. maybe because of the high power consumption? x86 cpu´s running at 528mhz would be more powerful than arm cpu´s. furthermore the device could run x86 os like xp embedded with more features and capabilities...
x86 CPU enabled systems are still too much power hungry and too much complicated to be used in such a small device (sounds weird when talking abut HTC Universal, doesn't it).
Why would a phone need it? Wouldn't battery life just suck?
Sent from the key to my world.
Sure, if you want a portable console lol.
The response speed would be great thought, and camera will be able to record in full HD without trouble. But, the software will need to be programmed to take advantage of the dual-core processor.
As for the battery, not necessary. The cpu will throttle back its speed a lot, and a dual-core might be able to drop really low and remain fully operational which will require less battery. Also the new dual-core cpu nanometer architecture would most probably be lower which means better battery consumption but at full load (like when playing graphically intensive games) battery probably won't last long. Still thought, new battery technology will need to be manufactured soon to keep up with this new phone technology. Next you'll see are dual-gpu phones lol
I'm waiting for the 2011 CES to see if anything dual-core will be announced before dropping $800 on a phone as I would love such a device, just for fun.
CES is just next week right?
They've already announced one phone to run it, I just think technology is getting crazy with portability. My computer still has a 1.6ghz processor, these new phones will undoubtedly surpass my poor system. Ha.
Sent from the key to my world.
One thing that the makers of the chips take into consideration, is power usage. And it's easy to see that too. I'll use desktop cpus and laptop cpus for example. Intel and AMD's 6 core designed both have a TDP of under 125W. Old single core pentiums had a TDP higher than that, and were much bigger in nm range. Laptop cpus now only use at the most, 1/4 the tdp of a desktop cpu.(Not as fast though)
Other than that, right now I can bet that there is no multi-threaded apps available, and is Android really able to take advantage of a multi-core system? Probably not on it's own.
HAPPY NEW YEAR people!!
Yeah, CES is just next week. I know they announced some phone but I would like to know when they are coming so I know if I should buy the best thing right now or not.
I wouldn't have a clue if Android can handle multicore processors but maybe the new Honeycomb version of Android will enable this? If this is the case then maybe this phones will come March/April....sigh
And yeah, TDP of this chips will be lower then current chips. I bet they are working hard to make the best use of the battery.

A multi core cpu does not necessarily use more power than a single core cpu; it's mostly dependent on the architecture.
NVIDIA talks about benefits of dual core:
http://www.engadget.com/2010/12/08/nvidia-touts-the-benefits-of-multi-core-processors-for-smartphon/
I think there is a definite need for Dual-Core Processors in phones. Gaming is making a mainstream shift from dedicated handheld gaming consoles to Smartphones. In order for developers to make more robust and graphically appealing games, they are going to need more processing power. Another point is that Dual-Core Processors will help browser rendering speeds. With HSPA+, WiMax, and LTE we are getting some serious downlink on our devices. But if you notice, a smartphone getting 3mbps down and one getting 10 mbps down renders a webpage at the same speed. Right now the processor bottlenecks webpage rendering, not our data connection. With these faster processors it helps eliminate the bottleneck to provide a gratifying web experience to the end-user.
It'll help if the application has multi-thread support. But if the app can only use 1 core/thread, then that's where dual core is useless. Also gaming isn't the main focus of Smartphones, there's probably a huge minority of people using their Smartphones as a serious gaming machine compared to people who are using their smartphone for work, talk, text, or other multimedia.
I know i'm gonna get burned at the stake for this one, since this is a tech forum, but dual core is just overkill AT THE PRESENT MOMENT. It's like computers. They are all now dualcore, most come with almost 4 gigs of ram. What in the hell would 95% of the population need AT THE MOMENT with something more powerful than that? LIke a quadcore with 8 gigs? NOTHING. It's just a ploy to get more money. Our 1ghz phones can run everything just fine. This isn't like the early days of android where it always felt like more ram and raw power was needed. We have hit a plateau where the current cellphone landscape fits MOST peoples needs. Can i really be the only one who thinks that it's just unnecessary?
Remember, xda only represents .0000000001% of actual real world use. I am talking about the layman who is actually gonna fall for the "OMFG ITS GONNA DO EVERYTHING SO MUCH BETTER AND FASTER", um no it's not. Most people dont even max out there current hardware.
Edit: Seriously people get a grip on reality. I'm not pushing my views on anyone. It's a ****ing forum, you know, one of those places where people discuss things??? The debate that has come out of this has been fantastic, and i have learned alot of things i didnt know. I'm not gonna change my original post to not confuse people reading the whole topic, but i can now understand why dual core does make some sense. Quit attacking me and making stuff so personal, it's uncalled for and frankly i'm about to ask a mod to close this topic cause it's getting so ridiculous. Learn how to have a debate without letting all the emotion get in the way or GTFO. YOUR the one with the problem, not me.
Xda doesn't care. We like specs, maxing out our devices, and most of all, benchmarking

Well as do i! I'm talking about the uneducated masses.
more cores mean;
more threads
meaning better apps
meaning better FPS
meaning HD everything
meaning more capabilities
meaning more fun with less devices.
Do you remember the days you had a cell phone, a PDA, an MP3 player, a digital camera AND a laptop? All that was missing is your bat symbol and cape. I like not having to have a utility belt of gadgets on my person.
I would rather see them work on battery saving and density technologies to eventually allow for one week [heavy usage] times.

Hard for you to believe, i know, but that's what having a multi-core does, it helps improve battery life (both in standby and in usage). Sure it's not a definitive answer to our battery problems, but it's a first.
Hey Lude219, I thought I'd post this as I thought you gave a good explanation on battery life and usage (fifth one down).
It really all comes down to the person's requirements. If someone requires to run several apps at once, or requires to watch movies at a higher frame rate, or requires to have the 'best phone on the market', then they'll buy a dual-core phone, no-one else will care (much). Most people I talk to agree and think that Dual-Core in a phone is unnecessary ('dual-core phone' it even sounds ridiculous lol), but, I must admit that I was surprised at how laggy my DHD was out the packet, and don't get me wrong, I know once it's rooted it will be much better just because the SW is cleaner, but most people will not even contemplate rooting their phone, so if it's not an option for them, dual-core will surely help.
Dual-core procs don't have a higher power consumption than single-core procs (or at least they won't if they design/implement them properly), so it shouldn't (fingers crossed) make power consumption any worse.
Personally, I'd also rather they put they're time and effort into making better batteries and improving general power consumption.
It'll be the next marketing point after the dual-core hype has ebbed (Now with Three Days Standby!! YEY!!)
Well i think most people who do buy these "powerful" devices have one important reason to buy, and that is to future proof themselves. But ey, i'm looking at the perspective of a tech savy guy, I suppose the masses simply want the next best thing.
But you are right however, it is a ploy to make money, but everything in business is, so there's no difference between dual core, one core, 8 mp camera, 5 mp, 720p. 1080p, it's all business. If there was no business then.. well, where'd we get our smartphones?

I can easily go into why you're wrong, but I won't waste the calories. Other things besides just adding a core are done to get those gains. If more cores equaled more power savings, ULV cpus would be octo-core.
Just a matter time when they get battery life ironed out in smartphones and to the OP i would agree in some aspect, but they are smartphones why not just keep improving them. Else if someone never thought outside box we would still stuck with dumb phones =no fun.
here a link for next gen snap dragons sounds promising.
I won't lie, right now dual core is overkill. But in time like everything else has computer wise, it will be the normal and will be the way all devices go, that's not just considering dual core. I'm talking pure multicore threading. It's not just the number of cores you're buying as well, it's the difference core to core when you compare say arm cortex a8 to the Tegra II's Arm Cortex a9, single core the a9 will be faster and more efficient and also produce less heat thanks to the die shrink, which then also means less power draw per core. Right now for phones, dual core is futureproofing a bit for when we do have android that is fully multithreaded, and apps that are as well.
There's also something you need to remember, XDA isn't really a big fraction of people using android devices and what not, but not every android user is on XDA. I also disagree with everyone maxing out their hardware, just running my Evo with a few of the aosp live wallpapers my evo runs terrible, and web browsing isn't the greatest either depending on the website.
Oh dude you should so post this one overclock.net, the beat down you would get would be hilarious. But anyway back one topic, as for phones, well for some people dual core is nice, for example me and my friends, when we head off to lecture, all we can do is browse the web on our phones, all of us, for some odd reason like to have at least 6-8 tabs open at the same time and for the phones we have (I have an iphone 3gs, theres a couple captivates, Droid Inc 2, and some others), they sometimes tend to slow down with all of the tabs open. Also when you open up numerous applications, you have to sometimes close out of some of them because the one that is open starts to slow down. Thats a couple reasons that dual core is nice, with massive multitasking. But with the computer part, where you say that no one needs a quad core processor, well think about it, there are a lot of people who want performance (not just XDA, theres overclock.net, techpowerup, EVGA, HardOCP, etc) and just random people who want fast computers for reasons such as video processing, gaming (this is probably a big reason), ridiculous multitasking (I fall into this category cause I have over 125 tabs open in chrome right now and I actually needed to upgrade to 8 gb's of ram because it was saying I was running out of ram with only 4), and some people that want just plain snappiness from their computer. So I would not say that a quad core processor is overkill for most people as the demographic I mentioned above does include a decent amount of people.
Oh and I forgot to mention watching Hi def videos, your average intel integrated graphics card cannot play a 1080p video without issues so thats why you might need a faster processor and a faster GPU to play those videos in an HTPC.
But yes for your average everyday joe, a simple nehalem based dual core would suffice for everyday tasks such as web browsing and such but it cannot do much else.

I completely disagree. The difference between dual and single core for mobile devices is *huge*. There is a *huge* difference between everything running "fine" and everything running "great". The biggest difference is for games and web browser, which most people absolutely care about. There is also the wide range of more powerful apps it enables, which for now is more important on the tablet, but that will come to phones as well.
Dual core is not overkill, for one, its future proofing your phone, most ppl buy the phones on contract and in a couple of months dual cores will be the standard for high end smartphones, second, it allows for better GPU performance which leads to better games and overall experience, there are many benefits to it, too many for me to list...

Yea, it's better if you don't, because I dont think you have any substantial knowledge on the matter to go against the research and knowledge of all the computer engineers out there.

It'll be interesting at least to see what develops. See if they'll start doing proper separate GPU Die's or if they'll dedicate GPU cores on the proc (i.e quad core chip with 2 CPU cores and 2 GPU cores).
Hope people don't start to get burnt when they begin maxing out/overclocking their cores.
Funny, if you stop developing you get nothing because you are satisfied with nothing.
Us at XDA are techies and you give us more core more ram more battery we will figure what to create with the new abilities. That is how progress is done.
As far as the masses, let marketing depts do their thing to them........we do not care, never did. As for me, I have a 12 core motherboard with 32 gigs of ram.etc and I jack it to 85% demand almost every day, and I am sure that there are very very few computers that have this capabilities.
The funny thing more innovation make more efficiencies my computer under a full load uses less than most of the gaming rigs out there and has 50% more muscle.
On the phone dual core allow one to create algorithms that will make the battery use way more efficient.
More cores more ram === win win win for everyone, but us in XDA and other forums like this it is just great great great for us.......... don't worry we will use what ever is created 110% and make it better.
If dual core in your Nokia 3210, yes it's overkilling, but if dual core in your cad workstation, it's been overkilled. All depends on the user, usage, and design of the device.
Actually it's an arueable question whether dual-core cpus are an overkill today, they have several advantages but most of those can be applied to netbooks and tablets rather than phones.
1. When there are several CPUs, multi-threaded applications can be really run concurrently (and basically, even if one application is performing, the scheduling overhead for multi-core system is lower and background tasks like gui/hardware drivers can be executed on a separate core).
2. Another use case (although this is a misuse and abuse of CPU anyway) is the use of multi-core systems for encoding/decoding media. It brings absolutely no advantages to the end user, but when the CPU is powerful enough to handle the media stream, one may use it instead of a proper DSP processor which Google will likely be doing for VP8/WebM
3. SMPs can be useful in tablets and netbooks - for example, tegra2 will outperform intel atom in most cases (first of all, it is dual-core. and secondly, it has a very powerful GPU). I am personally using debian on my tablet (in chroot though) and many people are using ubuntu on toshiba ac100 - arm SoCs are a fun to hack and give an incredible battery life. But this is IMHO only acceptable for geeks like us and I think dual-core (or x-whatever-core) ARM CPUs will be useful for consumers (hate this word but whatever) if some vendor releases a device which will run a full-fledged linux distro with LibreOffice, math packages like octave/maxima, development environments like kdevelop so that it can be used as an equal replacement of an x86 netbook.
As for the popular arguement about power consumption - surprisingly, but there is little correlation between the number of cores and power drain. Newer SoCs are more energy efficient because they have improvements in technical process (literally the length of wires inside the chip), more devices are integrated into one chip, more processing blocks can be put to sleep states. Even if you compare a qualcomm qsd8250 running at 1GHz with a GPU enabled, it will use less power than an old 520 MHz intel pxa270. Besides, as I have already mentioned, a multiprocessor system can execute tasks concurrently which means that the computation will take less time and the processor will spend more time in a power-saving state.
Basically multi-cores are a popular trend and is a good way to make consumers pay for new toys. For me personally the reasons to change a device have always been either the age of the device (when it literally began to fall apart) or the real improvements in hardware (I updated from Asus P525 to Xperia X1 because ever since I had my first pda I was frustrated by the tiny 32 or 64 mb ram and awful screens with large pixels that were really causing pain in eyes if one used them for long) but unfortunately the situation now is the same as it is in the desktop world - software quality is getting worse even faster than hardware improves. Hence we see crap like java and other managed code on PDAs and applications that require like 10 Mb ram to perform simple functions (which were like 100 Kb back in winmo days). I do admit that using more ram can allow to use more efficient algorithms (to reduce their computational complexity) and managed code allows for higher portability - but hey, we know that commercial software is not developed with the ideas of efficiency in mind - the only things corporations care about are writing the application as quick as possible and hide the source code.

That and yields for Nehalem 8 cores aren't so high. Bulldozer yields are working out okay so far, but then again it's not a real 8 core cpu...
Are really stupid. Between the governor differences, ram differences, thermal limit tweaks and whatever other little tweaks per phone/soc, what is the difference between Samsung or x OEM modding their phone to run full throttle and the consumer putting the phone in performance governor and running it full throttle? The benchmarks between phones with similar soc's have less merit than guaging against phones with different SOC's and checking performance against different generation SOC's. I think it is best that OEM' tweak their phones to run full throttle on benchmarks as it leaves less question about what is better/best. The benchmarks aren't all that scientific anyways with all the variables anyways. It was funny at first when people were crying about it but now it's just frustrating and another stupid first world problem for all the peeps with little weiners.
Now I do have a problem with tweaks that aren't available as a preset like running a cpu or GPU above frequency that the soc isn't rated for. That itself is deceiving. But running benchmarks similar to running a performance governor I have no problem with. Some of these big review sites need to get together and come up with a standard that leaves little question if the OEM is running the benchmarks above spec. Just smdh. Simple solution.
To me Samsung just makes the phone do what the so called benchmark app is supposed to do anyway...make the phone run full throttle. There is no difference than setting your gov to performance and running the test.

As there are much newer technology,some of them are enough for us or even overpowered.But the main problem is,Do we really need more than 4 cores?
Yes,some of them are about marketing,but i promise it won't be to much. From i know people around me thinks more cores means a better,faster phone...
There,Let's discuss why quad cores are better(if you stand at octa it's fine,just a little technical discuss),And why market prefers.
So we use a more simple way to explain why octa core is not better than a quad core phone.
"Uses a right,lower power processor to do some simple jobs"
No go away please.If 2/4 cores could handle flawlessly,why do we need those spare cores for?
Energy Consumption
Yes,refers to above,useless cores wastes more energy and your battery will drain faster if system/cpu governor is not totally optimized.

Actually,not many apps could take all 8 cores,and because based on big.LITTLE,those 8 cores can't be running at the same time.
But,It still have advantages:
Maybe,Benchmarking.
Yeah probably you will get a higher mark on core benchmarking,but so what?Experiences is on your own,benchmarking means nothing.
Using android as a workstation
Yeah that Maybe helps if you are using adobe clip editing tool on an android phone...
And Marking side makes more complicated.
Most of users which doesn't have/or having very little tech skills will just prefer an octa core phone because they will think the performance on a 8 core chipset is doubled.
And it may sounds cool,but there's too much drawbacks.
So,Conclusion:
Since nowadays phone are having too much spare power,and "fast"includes a lot of other parts in the chipset or phone like GPU,RAM,EMMC..etc
NONONO....We doesn't need more core,we need a BETTER core.
Think an apple i6 .Although i hate it,but there are only 2 cores and they performed pretty well.
And last,optimization is important in the first place,because if you even have 1000 cores,fail optimization makes it useless.

The problem is that application development in order to use the extra cores is difficult. Multithreading in applications increases complexity a great deal, introduces hard-to-reproduce bugs and worst of all - trying to use more cores may actually make the app slower.
While multithreaded applications might be able to get a boost with extra cores, I think the real benefit is better handling of multiple tasks (such as playing music and running navigation, with Bluetooth audio). I'm not sure that having more than four offers all that much benefit, though. I've certainly found quad-core phones to be more responsive compared to the dual-core models I've used.

Based on big.LITTLE,You could just split works to 2 different designed cpu,one is high density and one is more "Energy saving"(Actually it was just 4+4)
And for your example,i have found out that Bluetooth audio(Because communicating with more components on the phone,so it is considered as a high density work)
Also same as navigating.It is hard to program these applications to use the lower power cores.
