Snapdragon vs. Hummingbird vs. OMAP - the mobile CPU war beyond 1GHz

Texas Instruments OMAP4:

Bear in mind that all those generations of the Snapdragon family, plus the Hummingbird and Apple's A4, are still based on ARM's Cortex-A8 architecture despite being heavily customized. Even the dual-core Snapdragons will be a rehash of Cortex-A8 with 45nm technology.

One of the current big players, which announced a Cortex-A9 chipset that will be available for smartphones, is Texas Instruments. TI's current A8-based OMAP3 family can be found in various phones running the gamut of mobile operating systems. Its most popular reincarnations are perhaps the Motorola DROID line, and the Nokia N-series. The new DROID X has an OMAP 3630 chipset inside, clocked at 1GHz and produced with 45nm technology. Power management of TI's current flagship seems to be outstanding given the DROID X's claimed 8 hrs of talk time.

The OMAP4 generation is where it gets really interesting, but we are yet to hear for a handset with these A9 chips to be announced. Cortex-A9 is a completely different animal, focusing on multiple core operation, dual-channel memory controller, efficient instruction handling up to the application level, and overall superior power management. OMAP4 should offer what dual-core Snapdragons do, plus even better battery life, universal hardware decoding for playing any media file you get to it, and TI's superior image processing and stabilization technologies.

The OMAP4 family, however, doesn't come with an integrated baseband modem as Qualcomm's Snapdragon solution. The TI dual-core OMAP4 chipset is also running at the slower 1GHz speed, but knowing how prone to overclocking the OMAP chips are, difference in raw speeds should be negligible. In fact, TI itself is listing the cores as 1GHz+.

ST-Ericsson U8500:

There is another dual-core Cortex-A9 based smartphone SoC besides OMAP4, and from a very worthy contender. It is a creation of ST-Ericsson – a joint venture between Ericsson, whose wireless chips are found in more than half of the cell phones worldwide, and STMicroelectronics. The chipset is called U8500, supports up to 1.2GHz dual-core CPUs and, similarly to OMAP4, takes advantage of the rich SMP (Symmetric Multi-Processing) functionality that Cortex-A9 has to offer.

Considering all design awards U8500 received from Nokia, it might end up powering its Symbian^4 devices, but has been tested on Android and Linux too. The dual-core Snapdragons are said to be very similar in features to the U8500, which is rated for 12 hours of full HD video playback on a single charge of a standard 1000mAh battery, so hopefully this would be achieved in the latest Snapdragon chipsets as well. An advantage of the platform is that it integrates the baseband modem as Qualcomm's solution does.

finally a well thought out and written article on PA. The only thing that constantly bugs me is the abreviation of million. mln? Can ya just use M like most people.. I constantly find myself sounding it out... lol. cant wait for the next gen. If the next hummingbird has a 30% jump in battery life, that should put it inline with the A4/hummingbird, not past it. My vibrant gets almost a full day with me rarely putting the thing down. How many snapdragon handsets can do that? lol

Indeed - as I said over and over again - and continue to say once more - smartphones are the future. In several years almost every phone will be a smartphone. And the difference between the phone and the PC - aside from the screen size - will be minuscule

I agree with it all except for the screen size, especially with the 4.3 inch Droid X being about 1/3rd the size of my netbook screen. Albeit a netbook and PC are different I think smartphones will soon turn into 'Computer-Phones' with more user-friendly software for their slightly smaller size. PC's getting shrunk and smartphones going no more than 5ish inches. Just my .02

Yes well, you still will want to have that 50" screen in your flat to view stuff from your couch. But indeed - smartphones are the future. And everyone claiming that just because most people still use simple phones today and thus it is better to focus on them - needs to understand the above this.

mmmmm.. what a beautiful article. This site would be top notch if they are not so biased towards apple's Ios in their phone reviews.Especially if it is a close contender. Well done Phone Arena. (I hope you are reading this !!)

It's always cool to see my articles listed as sources, thanks! :) I will say this, my "Ruminations" post (your "more" source link) missed the mark on a few things (essentially, I was wrong about why the 45 nm OMAP 3630 in the Droid X was performing so well in Quadrant) but I explain my mistakes and some new findings based upon an article on AndroidAndMe here: In addition, I encourage anyone who is interested to check out's review of the Droid X's SoC, it's VERY well informed: (Page 4 cuts to the meat about the hardware) Also, an older article about the Nexus One covers Snapdragon pretty well: (Again, this cuts to the important stuff on page 8) And I'm looking forward to their review of the Galaxy S phones and the Hummingbird SoC. A lot of new information has come out since I wrote my Hummingbird vs Snapdragon article in April and I'm sure they'll be able to uncover even more secrets that I couldn't tease out of technical whitepapers.

Yes, can't wait for a Cortex A9 handset with TI's new chips to be benchmarked against the 3rd gen Snapdragons!

Did anyone notice that galaxy s is the best on the benchmark on any phone in the world, since the htc glacier isn't out yet. Samsung has really done a good job and can't wait for see what froyo would do.

I also remember a year ago the folks at MIT were working on technology that would offer a 3-10x increase in battery life. I think people are pretty habituated to charging their phones once a day or every other day, so combining these two things we'll see larger screens, smaller or more unique form factors, and even more processor-intense features.

Really good article. Had alot well put together information. Smartphones are the future, and like someone said above the only difference in a few years between a PC and smartphone will be the screen size.

Good general article. However, comparing battery hour between SoC is at best misleading. A poorly written driver can eat up all the battery no matter how good the SoC is at managing its power consumption. That is one of the reasons Apple does not support true multi-tasking + every application has to go through their inspection. Additionally, "Significantly improved battery life over the current generation" is not a guaranteed. At the transistor level, leakage power become dominant and is not easy to control. On top of that, newer generation of SoC has much more transistor than the older one. Take A9 for example, it has more transistors that the A8. Beside, compiling an A9 at 1.5GHz would nearly double the gate count compare to the same core at 1GHz. As software is not yet consolidated (various OS, graphic standards etc), SoC is still being built with many extra functions to cover all customers. As such, software role in manage these unused resource is critical in managing power consumption. Phone with the best software will win, and I think Apple proved that today.

Apple proved that their software wont win? because that's all I say in the iPhone 4 plus i get better battery life out of my droid than my sister gets out of her iPhone 4 and im a power user

As a young man growing up in the Bronx, an impoverished place full of youth that rather have the most expensive sneakers and phone than a good meal or diapers for the baby, am inclined to say that yes, a phone that can eliminate high tech peripherals is awsome. But, these companies should be working on cutting cost for the consumer, not lining their pockets with the blood of the poor. There are probably more smartphones in low class urban areas than in the whole world. This article is supurb in all its facts and actually giving people the information to make an educated decision. Yet I will add that as a capitalist society, these huge companies should invest more into educating the consumer on money mannagement. The more expensive gadgets are purchased the higher the crime rate goes. Food for Thought.

Very nice article - best I've seen on the subject - thank you The writing has been on the wall for some time - but this article provides the outline for play out over the next 12-18 months as one poster stated - all the computing power needed by most people will be available in 'phones' with an hdmi (wireless?) to a bigger display (hdtv, monitor, pico projector, etc) - input can vary between a folding bt keyboard, kinect, etc desktop/laptop is not dead - I still need 3d CAD (e.g Solidworks) or eagle for pcb's, etc - but 'phone'w/ exte4nal display will be fine for majority of users in coming years

I was researching about mobile phone processors and your article was of great help. There's not much info about mobile CPUs available on Internet, especially for a layman like me. Thank you so much.. Keep posting interesting stuff. There's one more detailed article about mobile CPUs and I would like to share the link -
