Windows Phone 7: The AnandTech Guide

The SoC
Given our transistor filled nature, one of our major concerns was discovering what System on Chip (SoC) lies at the heart of WP7S. This is especially the case given the strict, uniform hardware requirements stipulated for virtually all hardware manufacturers (it's like an iPhone made by 4 different companies?).
The basic hardware requirements are (as we mentioned earlier) the following:
- Capacitive Touch
- 4 or more contact points
- Sensors
- A-GPS, Accelerometer, Compass, Light, Proximity
- Camera
- 5 megapixels or more, flash required, camera button required
- Multimedia
- Common detailed specs, Codec Acceleration
- Memory
- 256 MB RAM or more, 8 GB Flash or more
- No external storage support (no SD cards)
- GPU
- DirectX 9 acceleration
- CPU
- ARMv7 Cortex/Scorpion or better
- Screen
- Two Supported Displays
- 480 x 800 WVGA : Aspect Ratio 3:5
- 320 x 480 HVGA : Aspect Ratio 2:3
However, we've dug up some more hardware details that are entirely new. Microsoft told me personally they've definitely already chosen a particular SoC, but aren't ready to state what it is. There's a dialog that takes place between OEMs, Microsoft, and carriers to decide on both the clocks and optimal performance/battery target for the device. My understanding is that this dialog is ongoing, and that the software giant will make a final announcement when it's settled. Although Microsoft has not announced whether it's the case, Qualcomm has already made an announcement of its own that Snapdragon lies at the core. We should know soon, but Tegra or any other choices are looking highly unlikely at this point. Speculate all you want, no amount of pressing would get Microsoft to disclose what they've chosen. We'll just have to be patient.
Hopefully Microsoft has chosen its WP7S SoC with the future in mind - the landscape will likely have changed significantly by Q4 2010, and Snapdragon as we know it today will be old news. Both the single core 8X50A Snapdragon at 1.3 GHz, as well as the 8X72 dual core Snapdragon at 1.5 GHz will likely have made their debut and start arriving in products by Q4 2010. It's entirely possible that one of these is the choices, but we just don't know yet.
The GPU
There's some interesting stuff going on with the GPU on WP7S. Although we don't know anything about the specific silicon, we know a lot about the software implementation that needs to be rounded up thoroughly.
Let's start from the beginning. Remember from the earlier article how WP7S runs code across two separate frameworks - Silverlight, and XNA? Each of these have their own set of hardware accelerated functions that directly leverage the GPU. Furthermore, you cannot mix and match Silverlight and XNA frameworks at present, something Microsoft hopes to eventually reconcile, but not, you guessed it, in this release.

MS will push the upgrades, not the carriers.shady28 - Sunday, March 21, 2010 - link
Wow, you know there are (were) really only 5 platforms in the smartphone space - Windows Mobile, Palm WebOS, Blackberry RIM, iPhone, and Android. All of them were unique in their own way and had their own 'fanbase'.
Now MS has removed their uniqueness. Rather than improving on WinMo, they've decided to try to go head to head against the iPhone by attempting to match up against the iPhone's strengths (ie, interface, ease of use, MP3 player integration, app store, etc).
Naturally they've failed to best the iPhone in those categories by a long shot. Instead they essentially have made a device that is 'less than an iPhone' rather than a better WinMO device. I'd say this is the move that will kill off WinMo.

Whatever you think of S60 and Maemo, Nokia still have a large share of the smartphone marketAzsen - Sunday, March 21, 2010 - link
Does Microsoft seriously think that home screen user interface looks good? It looks flippen hideous!! Give me iPhone UI any day.straubs - Monday, March 22, 2010 - link
No kiddding! Look at the Pre and then look at WP7S and tell me that doesn't look like something someone drew up in their basement in 1978. The single color and square corners are awful, not too mention huge amounts of wasted space everywhere.melgross - Sunday, March 21, 2010 - link
One thing that wasn't clear to me is whether or not music and books will be available without going through the marketplace. Apps can only be gotten there, so ok. The same thing is true for my iPhone. But I can get books, video and music onto the phone that weren't bought through the App Store or iTunes. Would that be possible here as well?The article didn't touch on that from what I saw. Anyone know?

I touched on it, but only very briefly ;) partly because it's, you guessed it, not totally finalized. Microsoft wants everything to go through the marketplace, so that means yes, music, videos, and games are all marketplace purchases.A lot of developers were asking whether there was any API for them to do in-application commerce, and the answer was that this was still being worked on. Think the same way you can buy additional levels or addons in-game on the iPhone that are billed through the App Store. It isn't present in the builds of WP7S - yet.
It's another one of those things they haven't fully fleshed out yet, and haven't decided whether they can finish in time for release.
I didn't hear any mention of books at all, that's a great point. I'm not sure whether there's any strategy there.
Cheers,

It looks like there is some complex sync process to transfer special types of file.You can't just plug in the phone, open it up as a storage device and drag files to and fro, as you can now.
Instead you probably need to install special sync software.
My advice: avoid and get a phone that is recognized as a storage device and has a usable file system.

Maybe it behaves like my ZuneHD. i just put music and audio books into my music folder and videos into my video folder. then it shows up in the Zune app. if i want to auto sync pics, vids, podcats and music it can or I can manually drag stuff the the ZuneHD device icon. oh you can either encode videos yourself or the app will do it for youMrPIppy - Sunday, March 21, 2010 - link
iPhone apps are sandboxed, but they are *not* managed code. Objective-C is compiled into ARM binaries, and garbage collection is not available on iPhone.
