This is all speculation of course, but who says I guy can't hope?

Well higher clock speed usually require higher voltage which shorten battery life and increase heat. I actually know nothing about the architecture of this processor and how efficient it is at stepping (I'm presuming it has a dynamic clock). Anyways I wouldn't mind either seeing some data on the impact of higher clock (both perf and effect on battery life) and perhaps having a user option to set it low or high or something to that effect (I'm assuming the impact on battery life is significant but that might be a bad assumption on my part).

If all things were equal, you're right - no such thing as a free lunch - so running faster means using more juice and lots of it goes to wasted heat.

In this case (for Evo users) - it's using a more advanced manufacturing process where the stuff in the SoC (transistors, etc, etc, etc...) are smaller and closer together - lots smaller. Smaller stuff takes less power to run than the same stuff when bigger.

So - in this case, if you put an Evo side by side with an equivalent made with the newer process, the newer one will be more power efficient - enter the Thunderbolt. In that case, tho, they made the battery smaller, so on that one, there wasn't the big gain in advantage.

In this case, the silicon is made with the smaller manufacturing process (45nm vs. 65) _and_ the battery is bigger.

The SoC - the MSM8660 - in the E3D does indeed have a dynamic clock like the Evo (it's pretty much the rule now).

And - we tend to expect a dual-core to run any given process at lower speed than if run on a single-core (providing things are optimized sufficiently for dual-core use - we won't know that until it's here).

Downside - higher resolution. With more dots to update on graphics-intensive tasks, more processing is required at the end. More pixels also mean more control transistors on the display itself (by definition for LCDs).

There are just too many factors to know in advance if this will act same, worse or better than an Evo on power.

It could be way more power-efficient - or it could be worse - we'll have to wait and see.

Could anybody tell, from the pics that had already been taken of the EVO 3D, if the batteries for the current EVO could possibly be used for the EVO 3d OR are the battery dimensions different this time around?

I consider the 3D aspect to be a gimick, I'm not sure I see all phones having this feature in the future, but even as a gimmick it's one I'm keen to try out.

The whole "3D at home" market is still in the early stages and I don't know if it will catch on, but one things for sure; if you can make your own 3D content then you're likely to consider a 3D tv.

I'm sure it won't be long until movie making software offers support for 3D media and that could be the thing that really drives it forwards; not Hollywood 3D movies, but 3D home movies of your kids parties, days out, etc. At some point watching them on your handset won't be good enough and you might then consider a nice new shiny 3D tv...

I concur. The 3D aspect of the phone is definitely more gimmicky than most of the other features of the phone. That aspect provides a wow factor easily seen. But the true wow factor for me is the muscle behind it. I can't me having the same attitude for this phone as I do for my 21 month old Pre in 22 months, either.

I just want it already. I don't know of any other Sprint devices coming that appeal to me as much, and I don't know how long I can resist turninig my Pre into a human launched projectile...

I'm really surprise a release date has not yet been given. I wonder if the 3d aspect is causing delays. Isn't the sensation basically the same hardware but without the second camera and software for 3d; or does the 3d feature actually require a different display technology beyond just software tweaks ?

The display itself is different plus 3D software on top of that.

Maybe you can inform me - what are some of the things you anticipate a dual-core phone being able to do better than a single core phone? I understand how dual-core processors help with parallelization, but what sort of apps would actually benefit from this? I suppose if you have widgets/apps running in the background it would allow them to work and your foreground app to still process data, possibly leading to a "snappier" feeling phone.

I've also heard that Android doesn't currently have very good support for parallelization - is this true? To what extent?

Multi-media stuff, including the Sense 3.0 UI. Games will benefit from the dual-core processor significantly as well.

Why all the dual core talk? You guys do realize every version of Android is written for single core and its going to be about a year before dual core is even utilized right? Bringing it up all the time is silly since its a non issue as of now.

You seem to have fallen for some FUD out there...

Excerpted from someone else:

Quote:
The Dalvik VM maps Java threads on Linux (native) pthreads 1:1, so SMP performance and behavior is just what the Linux kernel provides. IMHO Linux can distribute threads across multiple cores very well. If you want to know more, this is a good intro: http://oreilly.com/catalog/lin...

The point is that app developers have to do their homework and make use of threads whenever it makes sense. The Android API provides great tools to do that. Apart from the usual Java thread handling there are APIs to make it even easier for Android devs like for example AsyncTask (http://developer.android.com/r...

So I think Android is very well prepared for multi core hardware. It's just not true that Android doesn't support multi core processors.
Not to mention the lower voltages required to do the equivalent task on a single core. There's the improvement in power consumption as well (longer battery life).

My understanding is this: (big grain of salt required; I am not an expert)
- Android has supported SMP since 2009, though I don't know which OS version numbers that corresponds to
- Android supports multi-tasking, this should result in smoother performance in general with dual cores, and a slight single-app performance boost
- within-app SMP support is supported in 3.0+ and upcoming 2.4 releases; I can't easily determine whether e.g. the 2.3 series supports it

So you may be correct that few apps, and possibly none when run in 2.3.x, utilize dual-core within the app. As such, single-app performance gains from dual-core on this phone may be minimal until later Android releases.

But saying Android is "written for single core" seems a bit strong; heck, it's built on the 2.6 Linux kernel, which isn't exactly weak in the multi-core support department.....

(Edit: novox77 quoted a link which pointed right to threading support in API level 3, which corresponds to Android 1.5! So my original reading was incorrect; looking deeper, I may have been reading something obscure about supporting multi-threaded apps on single-core processors. So ignore that part.)

No, I don't realize that, honestly and not sarcastically.

Dual-core, general audience apps? Yeah, ok, that will take a little bit.

But at the heart of Android is Linux. In fact - take Linux, add the Dalvik Virtual Machine (that apps typically run in) and that's Android.

Android apps - within the Dalvik VM - are small and compact because they all call common system services - in other words, they call the Linux stuff.

And Linux has been multi-core aware and capable for some time.

All it really takes is a little kernel and system legerdemain and that dual-core will be giving immediate benefits.

And the HTC-customized Sense 3.0 is probably using the dual-core - and I have no doubt whatsoever that the 3D feature requires it in this case.

Maybe see also - http://androidforums.com/htc-evo-3d/305679-evo-3d-speculation-specs-3.html#post2617934

Anyway, my opinion is that it's far from silly and far from far future needed.

PS - Wow. A salvo response.

novox77 - have you considered rounding up the many good replies hereabouts for the wiki?

Surely these questions will all arise again when the phone is released.

definitely. i've taken some notes but haven't updated the wiki. maybe i'll get some of this dual core stuff posted.

A lot of what's in these threads is speculation, but whenever factual stuff is posted, I do note it. you want to author some stuff? could use the help.

I do get anonymous edits and additions, which is good. I could use someone who is very into the hardware specs of the phone, particularly CPU/GPU stuff; that's where I'm kinda weak.

Sorry, but you guys are wrong. Android is written for single core use only as of now. Go ahead and Google it. Here is just one article explaining it. Its capable of handling it, but Google doesnt even write Android for dual core and its probably about a year off.

So - it said we were exactly right.

Except for the part that Smartbench walks on water - I'll never agree to that.

In fact - leave out the benchmarking malarkey, and simplify the wording, and you've got my post above.

Yes but there are pretty much no apps written to take advantage of dual core, so whats the point? Its like having a 4G capable phone in a 3G only area. It wont matter.

Once more - apps are not monolithic in Android.

One part runs within the Android bit of the OS - the heavy lifting is done by the underlying Linux services, and this is most especially true for media-processing apps.

Apps may not be dual-core optimized yet - but if you provide that for the parts of the heavy-lifting services, immediate benefits accrue.

And nothing prevents native - read: non-Dalvik - apps from accruing those benefits, either. See: Sense 3.0 and 3D processes.

And then any apps that go on to engage in dual-core optimization simply continue the benefits accrual.

So - it's more like getting an immediate 3.5G while you wait for the 4G completion for some things, and total 4G for other things, all right away - and not like getting nothing as you state so far.

Immediate benefit:




Yes, this is the ideal. But as explained by previous posts, the linux-side of things will utilize the dual cores to some extent. You therefore get some reduction in power consumption that would not show up in any speed test benchmarks.

FocusFreak, I am an Android developer and you are mistaken on this issue. I would say that the vast majority of apps will benefit from dual cores. You do NOT need to write apps specifically for two (or more) cores. The Android OS will automatically take advantage of multiple cores assuming your app uses more than one thread.

Current best practices for Android development heavily rely on using background threads. You are not supposed to do ANY heavy lifting on the main (UI) thread, as this will stall the users' interaction with the device.

Android has specific APIs that even make this very easy. My apps all use background threads.

See this Google IO video from last year for more info on what I am referring to:
YouTube - Google I/O 2010 - Writing zippy Android apps

Even if the app you are currently running happens to only use one thread, if you had, say, Pandora playing music in the background - that process could spawn threads on the other core - making life easier on the app you have in the foreground.

Please stop spreading misinformation.

Well I think the problem with verizon and LTE phones is they can't decide how they want to deal with them. I suspect the 'outage' last week (and delay in the charger release) is related to something or other they will be announcing soon.

Btw any clue how the sensation screen will compare to the evo 3d (not so much dimension but fidelity; conversely does the hardware to support 3d make the screen nicer or less nice for 2d ?)

There may not be apps today that are specifically written for dual-core processors but that will change quickly; after all why would a developer write for something that isn't available? It's like the iPad2, it has only been out short while and there are already some apps that require the new dual-core chip.

Jensen nailed it. In the Android environment, you can't do any process intensive tasks on the foreground thread which processes GUI, otherwise you will end up with super-unresponsive apps. By this nature, you are pretty much forced to go multi-thread. As long as the version of Android used in the phone is SMP enabled, both cores will work at these threads independently, hence experiencing performance gains.

It is true that most apps of today won't utilize both cores to 100% all the time since the workload isn't split symmetrically, but still, a benefit is a benefit. Apps like Smartbench 2011 (I am the author) does symmetrically split workload within the app - I currently split the workload equally into 4 threads hence Smartbench 2011 will utilize 100% up to 4 cores when they become available.

Android is not iOS. Few of a the major development houses are putting any resources into Android at this time, and there is no sign of that changing due to androids fragmented environment.

Infinity Blade is an example of where iOS is going in terms of development budgets and resources from software development houses

However, we can count on ten more versions of Angry Birds and more fart sounds, which I am pretty sure doesn't require dual cores.

June 12th or the 19th most likely. Going to be a good day when it finally drops.

I'm really interested in seeing what content Sprint has planned for the Evo3D. Will they work with Netflix? Blockbuster? Youtube? What about Sprint TV?

I've seen quite a few 3D films in the last 12 months and will probably see many more this summer. A similar experience on a phone would be slick.

Video is all about field and sub-field processing - basically, what it takes to display a full frame of vid in that 24 or 60 frames per second you hear about.

For the processor, performing 3D field calculations and screen updates is basically a kinda doubling of that load (I'm simplifying to say that two things are processed for 3D in place of every one for 2D).

Because there ain't no such thing as a free lunch (TANSTAAFL), when doing 3D, the hardware can manage 720p - but when doing 2D it can manage 1080p.

The stuff on the motherboard can manage it all, but it seems some trade-offs must exist to support 3D at this time, and the trade-offs are on the 3D side, not the 2D side.

So for final image fidelity, that will come down to the actual displays used in the Evo 3D and the Sensation - and for that, we'll have to trust our eyes to make the final decision on the answer to your question.

I don't think I asked the question correctly. I meant for things like web browsing and general usage. Does having hardware support for 3d impact how well the screen handles 2d (not just processing power but sharpness; tonal range an so forth).

I'd wager yes.

The beefier 3D capable hardware should have no issues with 2D tasks, and make for a speedy user experience.

How much of an appreciable difference it will make over say, an Epic, or Thunderbolt is still unknown, but I wouldn't expect a massive bump in 2D performance due to the limitations of android and current apps.

By the time the apps and android catch up to the hardware, we will be talking about 2012's Evo.

Don't know - that will come down to the display itself (and how it was modified for 3D and how it implements qHD) - it could be a mess and a total dog or could be crystal clear and totally fantastic.

There are various ways to achieve no-glasses 3D - and we have no idea which way they're employing here - so we can't draw any inferences yet for 2D (normal, web, text, etc) performance.

I've charged that published benchmarks are not always valid because people quote them out of context - or what it is they do is not clear to end users and that it takes expert, objective help to interpret benchmark results properly (hence my crack that Smartbench doesn't walk on water earlier(*)).

Can you share - or provide links on your site to - info that might help us understand how to understand what your benchmarks mean and how to interpret the results?

(*) I used to write benchmarks for vector performance and compiler optimizations, back in the day, that were adopted by Cray Research; some of that old code made its eventual way elsewhere - and from that viewpoint, I feel qualified to say no benchmark walks on water, without it being personal to you, the author in this case.

Ok; I thought someone said hte display had to be physically different to support 3d; maybe I was mistaken.

Btw bestbuy employee told me the price was $200 on contract and $600 or $800 off contract. I suspect they just made up a number but maybe it will prove to be accurate. (I asked them if they knew the release date and they did not).

Thanks for correcting me guys. The iPad is a good example. However, I have had both the first iPad and now the iPad 2 and I still have yet to see any real differences in speed. I understand the benefits of dual core but in most real world cases, the benefits are not easily detected by the user.

It definitely has to be different - but there are many ways to achieve that difference.

One is to essentially have a kinda secondary lcd screen that overlays the primary, and the secondary does the chicken dance to achieve 3D, then goes fully transparent for 2D. Hypothetically, that could look great.

Other schemes could look great, too.

But others can be physically set or imprinted with surface lenses to achieve 3D and those might look bad when the content is 2D only.

They're not even throwing us buzzword bones on how they've achieved 3D here, so we can't even make a wild guess one way or the other intelligently.

I want to believe that they didn't do anything really stupid here - but the proof will come when users can see it and report results.

Ah - ok.

Android is based on Linux, so that uses what we call pre-emptive multitasking (just like Mac OS X, actually).

iOS as used on the iPhone/iPad uses what we call cooperative multitasking.

iOS apps ARE monolithic, unlike Android apps, and everything they do is basically self-contained - that's why an iOS app is typically bigger than its counterpart on Android.

In that iOS system, because the app does its own heavy lifting, each individual app may need to be re-done to really get the advantage of the iPad2 dual-core - the Apple stuff, including the app management, on the iPad2 is likely taking a lot of advantage of it right off, but you're not necessarily seeing it on many apps yet.

All of this increase on the Android side is predicated on the phone maker providing the system updates under the hood to make the Linux/GNU parts capable of using the dual-core stuff. From what I'm reading, some phone makers are doing a better job of that than others.

Because iOS apps are monolithic, a given app maker can actually optimize like crazy and develop absolute-performance, no-compromise dual-core apps - do not expect this in Android.

Because Android apps share common resources, all sharing rules are in effect.

Because there isn't sharing in iOS, perfectly ok for an iOS app to hog the heck out resources, it won't affect its sibling apps. (FWIW - it's this kind of app structuring that leads to Apple's products having different memory structuring, and requirements for more memory than Android for an overall capability equivalency.)

If this helps:

iOS multitasking is basically like that used in Win95.

Android multitasking is basically like that used in Win7.

The trade-offs are: Android, more even playing field for all apps to exploit dual core; iOS, more opportunity to have more advanced specialty apps than Android.

~~~~

The type of dual-core expansion that we call SMP (symmetric multi-processing) is really not terribly advanced or the most efficient way in the world to use multiple processors - but it is highly effective as a simple architecture. I wrote about half of an SMP operating system back in the day (in assembly!) that was used for defense avionics stuff, so I know.

Great explanation, thanks. I guess to make a dual core processor worth paying more to me, I would have to be wowed by its performance and see a big advantage in speed. Guess we will see when the 3D comes out.

OK - I did some searching, and came up with this Sense 3 demo.

Pop this out to full-screen 720p - and when the camera and the demo gal aren't moving around - screen looks very clear in 2D.

YouTube - HTC EVO 3D Sense User Interface Demonstration

From time to time, there's a sort of Fresnel-looking pattern on parts of the screen - I suspect that's just a video artifact from filming the display, it acts like an artifact - not part of the display itself.

And is it just me - or in the closeups, does the text seem to NOT have any of the artifacts associated with a pentile layout?

The white lettering edges just looked way too sharp to be pentile, but maybe I'm wrong.

Opinions?

Do you think there would be a pentile on this? While it's possible, it seems pretty unlikely. I can't think of any other HTC phone ever using pentile.

Are you considering the possibility it could be pentile simply because the Atrix shares the same resolution and has a pentile?

Personally I would be shocked if HTC suddenly decided to stick a pentile on the EVO3D, it wouldn't really make sense.

In the case of the Atrix, I don't believe it was any sort of limitation, but rather Motorola just being cheap.

......I typed that word entirely too much.

You've nailed it 100%, just taking the opportunity for a look-ahead to be certain.

PS - I think the AMOLED ones like the Dinc were pentile, but can't recall exactly. No big deal, that was an earlier generation supporting pentile only, if true.
