Paul Thurrott of Windows Supersite reports that Windows 8 is finally taking hardware acceleration seriously and will utilize the GPU across all applications. This hardware acceleration should make Windows 8 perform better and consume less power than if the setup were running Windows 7. With Microsoft finally willing to adopt modern hardware for performance and battery life I wonder when they will start using the GPU to accelerate tasks like file encryption.
It is painful when you have the right tool for the job but must use the wrong one.
Windows has, in fact, used graphics acceleration for quite some time albeit in fairly mundane and obvious ways. Windows Vista and Windows 7 brought forth the Windows Aero Glass look and feel. Aero was heavily reliant on Shader Model 2.0 GPU computing to the point that much of it would not run on anything less.
Washington State is not that far away from Oregon.
Microsoft is focusing their hardware acceleration efforts for Windows 8 on what they call mainstream graphics. 2D graphics and animation were traditionally CPU-based with a couple of applications such as Internet Explorer 9, Firefox, and eventually Chrome allowing the otherwise idle GPU to lend a helping hand. As such, Microsoft is talking up Direct2D and DirectWrite usage all throughout Windows 8 on a wide variety of hardware.
The driving force that neither Microsoft nor Paul Thurrott seems to directly acknowledge is battery life. Graphics Processors are considered power-hogs until just recently for almost anyone who assembles a higher-end gaming computer. Despite this, the GPU is actually more efficient at certain tasks than a CPU -- this is especially true when you consider the GPUs which will go into WinRT devices. The GPU will help the experience be more responsive and smooth but also consume less battery power. I guess Microsoft is finally believes that the time is right to bother using what you already have.
There are many more tasks which can be GPU accelerated than just graphics -- be it 3D or the new emphasis on 2D acceleration. Hopefully after Microsoft dips in their toe they will take the GPU more seriously as an all-around parallel task processor. Maybe now that they are implementing the GPU for all applications they can consider using it for all applications -- in all applications.

So Microsoft has officially stated in a blog post that their upcoming Windows 8 operating system will indeed be called “Windows 8” upon release and will come in four SKUs, three of which normal people will have use for and care about.
The three consumer oriented distributions or SKUs will be Windows 8, Windows 8 Pro, and Windows RT [previously Windows On Arm]. The fourth SKU will be Windows 8 Enterprise and it will take all the features of Windows 8 Pro and then sprinkle in some IT management and volume licensing goodies to keep the majority of their customers (businesses) happy.
Windows 8 (non Pro) is essentially the same feature level of operating system that Windows 7 Home Premium is now. On the other hand, Windows 8 Pro is what Windows 7 Ultimate is today. Both new Win 8 OSes are x86 and x64 based and will be the two consumer options available to upgrade to from Windows 7. Windows 8 delivers about what one would expect, media and general desktop features, multi-monitor support, media player, media center, Windows Defender, the Metro UI, Storage Spaces, and the updated Internet Explorer (among others). One interesting addition to Windows 8 (and Windows 8 Pro for that matter) is the ability to switch languages on the fly -- a feature that was previously reserved for the Ultimate edition of Windows.
Windows 8 Pro then incorporates all the features of Windows 8 and adds some important tools for worker bees and students including Group Policy, being a Remote Desktop host, BitLocker (and Bitlocker To Go) encryption, and the ability to join a domain (necessary for some students, depending on university). There are a few other goodies in the Pro version, but one nice touch is that the Pro version will be able to include Windows Media Center with an additional “media pack” download.
Windows RT is the third important SKU, despite the odd name. This new entrant is the official name for the ARM version of Windows 8. This version will only come pre-installed on certain computer systems (who have partnered with MS) meaning that Raspberry Pi users are out of luck and consumers will not be able to purchase Windows RT separately and install it on their own. This version will include the Windows desktop, language switching, multiple monitors, a VPN client, Windows Defender, device encryption (but no BitLocker), and a slew of Microsoft Office apps with updated touch-oriented interfaces. Windows RT takes many of the features of Windows 8 Pro but strips out a few things here and there to trim down the OS.
I’m glad that the previous rumors of approximately eight separate Windows 8 SKUs turned out to be false! Beyond that, I’m still absorbing the announcement and trying to figure out why they are calling it Windows RT (why not keep it simple and call it Windows On Arm). What are your thoughts on the announcement? Are you ready for Windows 8? A Microsoft chart with more information on the feature differences between the various SKUs can be found here.
