Graphics Processor - Windows Phone 7 Development and Hacking

Does the new hardware call for a graphics processor?
I know that Steve Jobs never sells a piece of hardware without a dedicated graphics processor, such as in the iPhone (PowerVR MBX-Lite graphics processor), or the Macbook (NVIDIA GeForce 9600M GT).
In windows machines, it is always an after-thought.

Snapdragon includes a perfectly reasonable graphics chip.

It just needs to be utilized with good drivers.

Like everything else, we'll have to wait for MIX. But with their massive push into gaming and focus on XNA, I have no doubt that the graphics capability will be at least as good as if not light years ahead of iPhone.

I sure do hope. But history says otherwise. MS never pushed for a graphics card with any of it's products as a "required" item. If the same happens here and Apple develops a new iphone 4gs with an even more powerful processor and as usual combine a dedicated graphics processor, then WP7 will be in the same boat as now.

What part of WP7 is like WM6? It's entirely different. Microsoft had practically no hardware requirements before, now they're being super strict. Gaming is a huge portion of their focus. We should know more next week at GDC. Besides, Snapdragon includes full 3d acceleration. There's no need for a discrete graphics chip as far as I'm aware.

What?! No, I said Snapdragon includes a perfectly reasonable graphics chip. How on Earth did you interpret that as meaning the exact opposite of what I said???
Snapdragon is not just a CPU. Snapdragon is a chipset, an entire mobile phone platform that consists of several separate chips. One of them is the CPU. Another of them is a graphics chip (or, if you prefer to phrase it that way, a "dedicated graphics processor") made by ATI/AMD. Honestly, have you never seen the Electopia demo running on a Snapdragon phone? The graphics are really quite impressive.
Yes, the Snapdragon GPU is somewhat less powerful than the one in the iPhone 3GS, but it's not an order of magnitude difference, and the faster CPU in Snapdragon (coupled with improved NEON instructions) somewhat compensates. Certainly the Snapdragon GPU is way more powerful than the one included with MSM72xx, and even that can run Xtrakt quite happily; it's miles ahead of the one in the iPhone 3G, too.

And thats for qsd8250.
Newer generation of snapdragon(msm8xxx and dual core QSD8672) has 4x greater performance than the snapdragon1. Don't know how's msm7x30 graphics performance. Besides we don't know which snapdragon chip will be used in windows phones.
It could either be qsd8650a which is 30% faster than the one used in HD2 or it could be the new msm7x30 or it could even be the high end msm8xxx which supports 1,3Ghz CPU, 1080p video and 4x faster GPU - hopefully it won't be qsd8250 which is manufactured at 65nm but something newer at 45nm. Power efficiency is very important, besides those newer chips just like tegra should be able to shutdown unused parts to minimize power consumption.

Out of curiosity - What's stopping WP7s manufacturers from using Tegra chips? I know Microsoft is working closely with Qualcomm, but does that automatically disqualify Nvidia as a supplier?

Well MS clearly stated that qualcomm is first chip supplier for Windows Phones. Probably in the future they will allow tegra, omap and probably samsung chips too.
For now we are stuck with snapdragon which isn't that bad IMO.

Drivers. MS isn't giving the OEMs as much control over the lower level OS and is developing all of the drivers themselves. No more will we have the problem of HTC deciding that 3d drivers aren't needed.

It will be sick if they annouce the msm8xxx being required and that's why HD2 isn't supported. I'd take that trade off.

Not all Snapdragon variants are actually intended to be used in phones. Most of the more powerful ones will only ever end up in netbooks and devices like that.

The decision to exclude Samsung processors surprised me a bit. Samsung's "Hummingbird" CPU is easily the equal of the current generation Snapdragon, and Samsung has been a major supporter of Windows Mobile in the past. I guess MS wanted to limit itself to writing drivers for just one platform - allowing Samsung or OMAP processors would mean also allowing other GPUs, other GPS and Bluetooth hardware, etc.

It's always sounded to me like they just picked one to launch with and will support others going forward. Writing drivers and testing other platforms at this point doesn't really give a good bang for the buck.
We should know on the 10th (the first GDC windows phone sessions). I would think the graphics capability would be something they would share there. But then again, they've shown an astounding ability to just say "wait for MIX" so far so they very well could keep that up.

I imagine that they want WP7 to be as smooth and hitch-free as possible to start out with. That means not allowing for any unknown variables such as different hardware, drivers, software.
It's the same for Iphone or any of the console game machines. It's one piece of hardware that is always the same making it easier to plan things for and develop things for. Which ends up meaning a higher perception of quality from the consumers due to lack of glitches and crashes.
Hence Apple's commercials saying how often PCs crash and stuff. They crash because PCs have way more variables as far as hardware and drivers than Macs have making many more incompatibilities.
Microsoft will probably allow other hardware once WP7 has a good name going in the consumers eyes.

You're right. QSD8672 is targeted at smartbooks but msm8xxx is designed to power both smarphones and smartbooks. Besides OMAP4 and tegra2 are powerful but still we can expect smartphones based on those platforms next year.

I think so too. More hardware platforms mean more work to do. So I think that support for other hardware platforms will come after they'll finish V1 of WP7 - this way they will just have to port complete full OS from snapdragon to other platform.

Google Earth in Windows Mobile?

At iPhone 3GS there is Google Earth with 3D view of some places mainly monuments, buildings and streets. In Windows Mobile there is Google Maps which is not so powerful.
Is there Google Earth to Windows Mobile? Please inform.
If not, is there some limitation in Windows Mobile devices to run Google Earth?
Thanks.
Remember that the iphone 3GS has the new generation of arm chipsets, just like Palm Pre (coretex A8 or something along those lines). The next generation of HTC products (some rumored to come out this year) will have similar chipsets, some of them more powerful if I'm not mistaken...
There's always been a problem with 3D graphics on this generation of Qualcomm chipsets due to the question of proper drivers. So I don't know if the current chipset is capable, but even if it were, I doubt it'd handle Google Earth without the proper drivers.
I don't know if the mobile version will suffer from it, but the full PC version of google earth has never been stable and has cause lots of PC's to blue screen.
OP: nope- looks like there's no Google Earth client for WM.

Well, the Google Earth app runs on the iPhone/iPhone 3G as well, which has a 412 MHz ARM11 CPU and a PowerVR MBX-Lite GPU (a lot slower than the 3GS' Cortex A8 CPU and PowerVR SGX535 GPU). The Qualcomm MSM7200's ATI Imageon GPU hardware is actually theoretically faster than the MBX-Lite, but the implementation is, for whatever reason (drivers, etc.), a lot slower.
So yeah, I'm inclined to think that Google might be concerned about graphics limitations here, because even Google's own Android OS doesn't have a Google Earth client yet-- presumably because most of the popular Android devices are HTC phones with the same MSM7200 internals.
I have Pro 2 and in general I'm satisfied with it. But also I have access to an iPhone 3GS and I can assure that iPhone is a very fast device, far faster than Pro2. So, I don´t understand:
1 - Why iPhone has no video call?!!!
2 - Why iPhone is so faster compared with Pro2?!!
3 - Why HTC is disable to put graphic part of CPU working?!!!
On the contrary than it´s said, there is an application that permit iPhone to be a multi task device.
Racing car games on iPhone run so well like a PC, and the same with Google Earth. It's incredible the speed of iPhone in all applications. Also there are hundred of applications to iPhone.
However I don´t know why iPhone GPS only works properly with Navigon and not so well with Tomtom!!!
If iPhone had video call, a better GPS and a 800x480 screen (it's only 480x320 - 3.5"), it would be by far the best device in the market mainly due to the speed of it.

There are a few reasons for this- first, the iPhone 3GS has far superior processing power compared to the TP2, and second, WM can't even make full use of what power the TP2 does have.
To address the first point, the 3GS has an ARM Cortex A8 CPU at 600 MHz (867 MHz underclocked for heat/power savings). Cortex A8 is twice as fast, clock-for-clock, as the ARM11 architecture. The TP2's Qualcomm MSM7200 CPU has an ARM11 at 528 MHz, so in raw processing power, the 3GS is 2-3x faster. Further, MSM7200 lacks ARM11's VFP option, so all floating-point operations are done by software, while the Cortex A8 has the NEON floating-point accelerator. As a result, the 3GS is 40-50x faster than the TP2 at floating-point operations, which iPhone OS X uses quite heavily.
On the graphics end, Apple chose to pair the Cortex A8 with a PowerVR SGX 535 GPU, which blows away everything short of Tegra (about 40% slower than Tegra's GPU, but Tegra's CPU is a slow 600 MHz ARM11, so 3GS' CPU is >200% faster). The SGX 535 is even faster than the Qualcomm Snapdragon's GPU (an ATI Imageon Z430), and from what's been seen so far, the 3GS' GPU is often 10-30x faster than HTC's implementation of the MSM7200 (in TP2/TD2/G1/etc.).
Now onto the second point- Windows CE, which underpins Windows Mobile, only targets the ancient ARMv5 instruction set, so it can't take advantage of newer CPU features, like hardware floating-point units. In addition, WM lacks a composited desktop- so while the iPhone/Pre/Android OSes all use GPU acceleration to handle their UI, WM relies on the CPU, so it can never be as smooth, for the same reason that Windows XP's UI can never be quite as smooth as Vista/7 (which have GPU-composited desktops).
So the result of that is that even if you feed WM a lot of processing power, it won't perform as well as other mobile OSes due to its ancient architecture. See the Toshiba TG01, for example- its 1 GHz Snapdragon CPU (whose architecture is even faster than Cortex A8) is over 60% faster than the 3GS', and its GPU is almost as fast, yet in many cases the 3GS still blows it away in usability and app performance.
HTC saved money by going with the same old Qualcomm MSM7200 chipset for the TP2/TD2, but in reality, even a Snapdragon chip wouldn't solve WM's architectural deficiencies. That won't change until MS moves beyond CE5/6 (probably with WM7 in late 2010).
Stock iPhones can't multitask beyond Apple's own included apps (iTunes, Mail, etc.), but if you jailbreak the phone (a simple 5-minute process- much simpler than flashing a WM ROM), apps like Backgrounder let you multitask. Apple thoroughly optimized its software to extract the most out of its hardware, and it really shows if you push the phone hard-- even the original iPhone/3G perform quite well given their hardware.
As for video calling, no US carrier supports it, and even in Europe, usage rates are abysmal and the quality's usually poor, so it doesn't make too much sense for Apple to integrate until it can guarantee an iChat-quality video experience.

Actually, the OS targets ARMv4 so it's even worse, but makes it great to backport the OS to ancient devices.
However, the OS can take advantage of hardware FPU (detects for it even), but NO ODM will turn on the necessary OS support for it even if they ship a device with FPU in it, such as the S3C6410 in the OmniaII/Acer *900, and all the Snapdragon devices. They're all really lazy and enforces that if MS doesn't hand it on a silver platter to them, they won't make it themselves. They rather make more money shipping as many shoddy devices as possible (HTC).
So WM is a pretty poor platform to be on especially with a MSM7200 cpu crippling everybody. Google would be smart to dump HTC/Qualcomm's shackles and move to a modern platform for Android, and WM won't get there first.
It would be especially smart to just stop buying ANY device with a MSM7200 cpu in it unless all you want is feature-phone capabilities.

Snapdragon's GPU hardware is almost as powerful as the iPhone 3GS' (though driver implementation is still less than optimal), so I'm sure it could handle a Google Earth client. That said, Google's unlikely to release one for WM at this point...
Wow. Now that I am thoughly depressed that I paid 4x as much for my slower and less useful TP2 than for an iphone, I am going to have a hard time paying hte bill on this thing!

WP7 minimum requirements

WP7 calls for a minimum of 1ghz processor.
That does make me think - how come the competition is able to provide smooth UI with 600mhz phones? ie. android / iphone / palm pre?
Is the WP7 so much processor hungry? that is calling for trouble...
your thoughts please.
The demo shown was using non-final build of the OS.
Something like BETA version, not yet final version.
There you would expect: bugs, glitch, errors, etc.
But still, it is quite impressive.
We can only judge the "perfectness" of the OS later when it has been "OFFICIALLY" released.

It's about more than just the basic UI. Lots of background stuff going on. All those live tiles need CPU power to populate. The Zune HD with a similar UI is only 600mhz. Microsoft is just setting the bar high so that the entire device is snappy. Compare the experience of an Android phone on a Snapdragon to that of a lesser CPU and there's a big speed difference. Microsoft is just demanding the best and it gives them more room to grow. If they set the bar low, the devices will be obsolete much sooner. Besides, faster stuff will likely be out by the end of the year and 1ghz will be somewhat commonplace. Apple's iPad is 1ghz and if they release an updated iPhone later this year I'd bet it will be 1ghz as well.
who's to say it needs all 1GHz? i think they're doing a great thing by setting that as minimum. our devices would be up to date much longer or at least it will feel that way. It's a good sign for those who don't like upgrading every year, no?
Besides, the Nexus One is 1ghz.... Supersonic will probably be 1ghz..... Everything will be 1ghz by the time wp7 comes out, if not more.

What he said. It's set because it's very doable.. at the end of this year, which manufacturer would expect a new device to be competitive using an old processor? Setting a bare minimum as the minimum would mean that you have 7 Series phones which perform much crappier than others.. a situation they want to avoid.
Plus it's mobile XBox.

the new qualcomm 1.5 ghz chip is not meant for mobile devices till now it is used for mini notebooks the one which will be avaliable for devices is the 1.3 ghz version same specifications as the 1ghz processor but with 45 nm technology( uses less power ) same graphics performance but with 300 mhz over clock speed nearly same performance but less power consumption
Where does it say 1GHz is required? Right: Nowhere.
An ARMv7 processor is required. iPhone/Pre/Droid all have ARMv7 processors.

i think 1ghz is enough for a mobile os (the win xp runs on 500mhz processor and on 128 of ram )
It's not all about the clock rate. An ARMv7 processor at 500MHz is about twice as fast as an ARMv6 processor at the same clock speed.
(that's why the iPhone 3GS is so much faster than the iPhone 3G, despite only having 200Mhz more)
Windows XP doesn't run on ARM processors at all.

Well I'm sure they could, but Microsoft wants there to be very high minimum specs that developers can expect so that all apps can take advantage of the hardware to its full extent. An example would be the way WinMo apps are now. Most 3D apps aren't very good because the minimum of what developers can expect in a device isn't very high; thus, they have have to make it use as little resources as possible.
Based on what I'm hearing most current 6.X phones will be unsupported unless they pack a Dragoon. I hope the scorpion CPU is used in a win7 phone.

Snapdragon can run at lower clock rates as well (e.g. 768Mhz in the Acer Liquid).
They also have slower processors besides Snapdragon (though I don't know whether the 7227 is ARMv7, I don't care about low end devices ).

Any CPU can be underclocked. The "normal" speed for Snapdragons is 1ghz.
Qualcomm specifically mentioned that the Snapdragon had been chosen for WP7.
How about the famous HTC graphic acceleration driver?
I hope this time there will be no more missing graphics driver for WP7!

Gaming on WP7S

Watch this amazing video
http://www.youtube.com/watch?v=LQv_3fwopo8
The guy plays from PC to WP7S then continues to Xbox360. Codes on different platform is almost the same!
Wow, that's cool. Not much of a game of course, and I don't know if real game developers use Visual Studio, but that's the kind of synergy that's really a theoretical killer feature for the WP7 as a platform.

Real devs of all types (besides *nix I suppose) use Visual Studio. There's plenty of "real" games already using XNA as well as community games. It's rapid (ie cheap) and yet still rather powerful. Yea, you lose a bit in performance since it's managed but it's not too far off.
The guy mentioned that this is the entertainment scenario and he also said that he has shown the productivity scenario. Could this mean that you can seamlessly work from your PC to your Phone and vice versa?
Just curious, How fast the Zune HD Tegra processor compared to 1 GHz Snapdragon chip (for example: HD2) ?
Anyone know any good benchmark result?
I don't have any hard numbers and I doubt they exist. Mobile platforms vary so much it would be hard to get a fair comparison.
But judging from what I've read, th Tegra would be pretty close when it comes to 3d rendering and video however the Snapdragon would eat it's lunch when it comes to general purpose stuff. It's running the newer ARM architecture and is clocked much higher. The Tegra seems at home in media stuff (Zune HD, portable game consoles, etc) but Snapdragon wins on phones which make more use of the general purpose ARM CPU core instead of the graphics hardware.
Thanks Rusty,
I read more now and I think the main reason would be that Snapdragon has cellular communication and GPS built-in, proven and being used already. While Tegra does not have that, but more powerful on media.

Will future versions feature multi-core processors??

Hi,
Not to long ago samsung released their new dual core processor "Orion" with has some amazing specs. They says it will be up for mass production in frist half of 2011.
Both qualcomm and lg has also new smartphone processors coming next year.
Will future windows phone 7 devices feature this? The snapdragon in the current devices is kinda outdated...
My ultimate windows phone 7 phone would feature:
512 meg ram or more
at least 1GHz Orion or similar dual core processor
800 x 480 or greater super-amoled multitouch screen
4" screen
Sleak design in aluminium
Yeah.
WP7 will get put onto all the new software as its needs to compete with Android and the iPhone.
Although the 1GHz snapdragon is a little outdated now i think some people don't realise that it is still a beast of a processor, and WP7 has been specifically designed to run perfectly on it as it was the minimum requirement for Hardware Manufacturers don't forget.
Having Qualcomms "Still in Development" 1.5 Dual Core inside a device would be fantastic, but it's not going to happen anytime soon (2012 at the earliest) and for the time being that doesn't bother me the slightest as my HD7 runs smooth as anything with what it's got. I doubt a dual-core processor would increase the usuability of any of the WP7 Phones, the only thing it would do is reduce loading times of App's/Games/etc, which is currently only seconds anyway.
Agreed, I believe in Q2 2011, the processors will finally be available for manufactures

True but what about Samsungs Orion then?
The other reason why im waiting for a New wp7 device is the lack of exchangeable storage on all devices...
my only concern is about the compatibility of the Phones with LTE technology as Verizon's LTE network will be up in my area by the end of the year.
i'm waiting 1G ram with using nvidia Tegra 2 cpu + 5-7 point mutil touch
CE7 supports multi-core ARM CPUs. There are plans to move WP7 to CE7 (it's currently on a CE6/7 variant) later on. That should happen before dual core chips are a reality so there's no reason Microsoft won't move to it. I would guess that would come with a major software and hardware spec update, maybe WP8. There's no point in tossing the current WP7 on much more powerful hardware because the software won't take advantage of it. Games and apps will still be targeted at the 1ghz SnapDragon so basically things will just load faster.
People really need to get out of this hardware spec mentality. It doesn't matter if the phone had a 100mhz CPU if it performs well. I know that's hard if you're a techy but you have to focus on the end result, not the pieces that make it happen.

Is this for real? Why would you need 5-7 touch points? Can you even fit 7 fingers on a 4in screen?
I sure as hell hope that Microsoft won't allow this on Pad devices.
Sure the idea with Pad devices might be good, but not with an OS built for a 4" display.

yeah, if MS comes out with a pad, I hope they alter the OS or make a new one optimized for a pad sized screen.

All these quad core android leaks, What MS needs to do

I am seeing all of these crazy quad core android leaks now and windows phone will get even more behind in specs. Look i know that most apps wont even utilize the quad core, there are barely any apps that do dual core but Apollo better be groundbreaking and allow quad core cause that is where MS needs to compete. At this rate i think the next iPhone too will be outdated on release.
wp7 doesn't need quad core, in fact, 99% of the smartphone users don't even need a dual core.
you'll see these quad core phones with a huge price tag, low battery life and performing the same as single/dual core devices.
it's completely unnecessary. it's not like you're running lightroom and premiere on your phone.

My concern is with heat dissipation with all that processor power. In addition to my DVP, I have a MyTouch4G Slide - 1.2 ghz dual core - and it can get hot when you are using it. I am curious to see what the longevity of these 1st gen dual cores are based on my experience with the heat. My DVP seldom gets hot, neither did my nexus one for that matter. Just a thought...........
smoked by a windows phone
Haven't you seen any of the Smoked By Windows Phone challenges? A Windows phone is faster than any of the android or iphones out there with dual core processors. IMO thats saying something.
I'm kinda fed up by these donkheads using Android who talks about nothing but specs. You can put WHATEVER you want in that ****ing OS and it will still not run smooth because IT IS NOT OPTIMIZED FOR ****.
aren't these new procs supposed to be more efficient and cooler than the previous batch?
Its stupid that android is desperately trying to become more and more like a desktop PC.

Quad cores are nice and stuff but they suck up a lot of battery power add that to the already 4G sucking up most of it and you get a phone that you have to charge every few hours a day. It's like a laptop with a cell phone battery.

This comment is ridiculous when you remember windows phone 8 is a desktop OS on a phone. well at least the kernel.
Quad cores however, are not needed on a phone at this point of time. Tablets yes, phones no. But to all that worry, Apollo is coming out this year

well u know what I mean, I meant it by the hardware standpoint.
I do think that Windows Phone needs to enter the dual core market for the gaming segment. Quad core is not necessary now and I suspect the Android market will not be dominated by quad cores in 2012.
But we do have to face facts, if (and I am not saying this is indeed a fact) the consumer wants a dual core then sales will not be where you want them to be if you are pushing out single cores. And so on. Imagine an OEM only making 3.2MP point and shoot cameras because that is enough to print on 8.5x11.

It's exactly what I was going to say.... Xbox live titles are pretty good and they are getting better but, still not even close to some RPGs or Rage on the iphone or Android for graphics detail, quality and game play.
Xbox live is a brand that is known for great games, As a gamer, I am disapointed in the offerings given on my WP7 device. They are good but, not great.
Quad cores are just too much (battery and heat are the big ones), crap, to do better games, just give a better GPU, no quad core or even dual core is needed in most cases.

absolutely agree, this is exactly why my device thats near on 2.5 YEARS old still kicks the balls off devices made yesterday
However, graphically intensive tasks are hampered by its aging Adreno 200 GPU
I believe the younger brother of my phone the HD7 had the Adreno 205 which gave it a significant bump, personally, i want the S3 Snapdragons, not for the multiple cores but the new Adreno 220/225.
The old S1 processor in my thing is still standing true, shoving 3 or even another 1 core in it is going to make the square route of bugger all difference in my every day needs.
The only reason for WP7 to have more CPU power is for gaming (and for the spec sheets of course). I am sure Apollo will bring multi-core support which will enable even better games. As it goes, some of the xbox live titles are fairly impressive, but there are games on other platforms which are significantly better due to the power available.
The only thing I have seen mentioned in this thread that is worth having more power for other than games, is 1080p video recording. It definitely does make a difference - I have a camera that does 1080p and it is very very nice. Cant wait for that, although I have a sneaky feeling that the second gen devices could do it if the software allowed it - correct me if I am wrong.
Yes, don't change Windows Phone! Keep it as it has always been. The first Gen devices from two years ago are sufficient, so there is no need for improvement! You see how great they sell!
Maybe quad core is a bit much on a phone (whereas I could imagine having one in my tablet), but if it improves multitasking, saves battery at the same time and makes speedier cameras, faster web browsing and better games possible- then fine, give the people the chance to buy these devices. Not everyone may need them (they buy the middle class models with the last gen hardware) but there definitely is a market.
And yes, imo Android devices are way faster than WP7 devices, equally smooth and offer a superior interface which looks better and offers far more options - a matter of taste!

You ignore the fact that most sales people completely ignore selling WP7 over the easy sell of Android and iOS.

Sorry... seen way too many laggy Android ROMs and devices to fully believe this statement. Whereas, every WP7 device has been consistently smooth. Superior interface is purely subjective.
