Windows 8 VS. Windows 7: Fight!
Windows 8 haters have already labeled the new OS as the second coming of Windows Vista, but those who can contain their bile know that Win 8 is likely to be far from the performance-sucking, driver-breaking Windows Vista in its pre-SP1 days.
To find out how Windows 8 compares to the lithe Windows 7, we took an Asus P8Z77-V Premium board; inserted a Core i7-3770K, a GeForce GTX 690, 8GB of DDR3/1866, and an OCZ Vertex 4 SSD; loaded up Windows 7 Professional SP1; and ran our benchmarks. We then took an identical Vertex 4 SSD, loaded up Windows 8 Professional, and reran our benchmarks. We used the same beta 304.79 GeForce drivers for both and the latest beta drivers available from Asus for our testing.
The verdict? We expected the scores to be nearly identical, and for the most part they were. As Windows 8 is built on the foundation of Windows 7, we didn’t expect a quantum shift here, but we did see some performance differences. The most glaring difference was in PCMark 7, where Windows 8 produced significantly faster scores in the creativity and computation tests.
Why such a huge difference? We suspect it’s the result of changes to Windows Media Foundation in Win 8. Windows Media Foundation is Microsoft’s replacement for DirectShow, which was implemented in Windows Vista. 3DMark 11 also showed a difference, but in Windows 7’s favor, by a smaller percentage, in the physics and combined score. The difference there is likely due to some efficiency with the Bullet Physics engine that FutureMark uses in the test. More importantly, the graphics score is the same between operating systems, which tells us there should be no difference when gaming in Windows 7 or Windows 8—at least on Nvidia hardware.
Windows 8 includes native USB 3.0 support, and we saw it smoking the stock Windows 7 USB 3.0 performance by a hefty margin. Our Asus board, however, includes a Turbo mode, which puts it within striking range of Windows 8. USB 3.0 performance on Windows 8, for the most part, is pretty awesome, though.
The rest of our tests were mostly a wash except in two interesting instances: Cinebench 11.5 and X264 HD 5.0.1. Both are multithreaded like mad, and both show about a 5 percent advantage in Windows 8. This could quite possibly be a sign of the improved scheduler in Windows 8.
Check out what we hope to see in SP1 for Windows 8 in our "What we hope to see in Service Pack 1" story.
To sum up, Windows 8 performance is generally the same as Windows 7, with a performance edge in anything that uses the Windows Media Foundation and likely anything that is heavily multithreaded. USB 3.0 is also markedly improved. We do note the issue with Bullet Physics in 3DMark 11, but we don’t think it’s a very serious issue. So all you haters better find something else to hate on.

Early Birds Get Preferred Pricing
Microsoft has simplified the editions and prices of Windows 8—at least compared to how the company initially segmented its first batches of Windows 7. However, folks considering an upgrade won’t want to delay for too long, as Microsoft is also offering early birds a significant discount on Windows 8.
Windows 8, in total, will arrive in four versions: Windows RT, the ARM version of the OS that comes preinstalled on supported devices; Windows 8; Windows 8 Pro; and Windows 8 Enterprise.
If you’re already running Windows XP, Vista, or 7, you can upgrade to Windows 8 Pro for $39 until January 31, 2013. That’s just for a digital download; retail copies will cost $69 until the deadline, when the Pro price will then bump to $199. There’s no word, as of this article’s writing, how much Windows 8 (standard version) might cost.
Still, compare that to the pricing scheme for the three major versions of Windows 7 currently on the market: $119 for Home Premium, $199 for Professional, and $219 for Ultimate. To Microsoft’s credit, the company did offer similar discount pricing for Windows users shortly after Windows 7’s 2009 launch—a final cost of $50, $100, and $219, respectively.
Playing on price is Microsoft’s answer to the inexpensive upgrades Apple enthusiasts have enjoyed for years now. It also might just be Windows 8’s ticket to increased adoption rates in the face of Metro’s heavier criticisms.
Minimize Metro’s Annoyances
As mentioned, Windows 8’s Metro isn’t the simplest of interfaces to navigate—especially if you’re stuck on a good-ol’ keyboard and mouse. However, there are still a few tricks you can use to streamline and customize your way through (or around) Microsoft’s “tablet” portion of the OS.
For starters, make sure you fire up Windows’ Default Programs app—found by typing “default” into the Metro UI—and use it to set Windows Photo Viewer and Windows Media Player as the default apps for all file types they can open. This allows you to bypass the annoyance of jumping into Metro Photos or Video whenever you click on a related file in File Explorer.
If you want to avoid Windows 8’s app management entirely, don’t pin your most-used apps as Metro tiles; pin them to your taskbar. The bottom of your desktop screen might get a little cluttered, but at least you won’t have to hunt down your apps within Metro.
One of our favorite tricks allows you to bypass having to jump into Metro from the desktop to run Metro apps. Make a shortcut on your desktop and type this in for the item location: %windir%\explorer.exe shell:::{4234d49b-0245-4df3-b780-3893943456e1}
Your shortcut will pull up Windows 8’s Applications window, which will let you launch Metro apps directly from the desktop.
For a more intense Metro transformation, check out the third-party app Classic Shell (classicshell.sourceforge.net). Not only can you bring the long-lost Start Menu back into Windows 8, but you’ll also be able to boot directly to Windows 8’s desktop instead of its Metro UI. Additionally, you can also completely disable a number of portions of the Windows 8 Metro UI: Hotspots, the Charms Bar, etc.
Windows 8 also includes a number of useful tweaks within its Group Policy Editor, including the ability to bypass Windows 8’s lock screen for faster logging-on. It won’t spare you from Metro, but it’ll at least help you get to your safe and friendly desktop even faster.

Windows 8's Applications window is the sure-fire way to launch Metro apps without first haivng to jump into Metro
Windows 8: Under the Hood
While the new Metro UI will be what catches your attention in Microsoft’s latest OS, there’s actually far more under the hood that offers tangible performance benefits.
USB 3.0 Native Drivers
Windows 8 brings native USB 3.0 drivers to the mix, so no longer will you have to hunt for USB 3.0 drivers after your clean install. Even better, USB 3.0 performance is greatly increased with the native Microsoft drivers, too.
Windows Acceleration
Windows 8’s implementation of Direct2D—the API for hardware-accelerating text, bitmaps, and other UI elements—offers a huge leap in performance over Windows 7 by relying on DirectX 11.1 to accelerate 2D graphics. Other improvements include 60 percent faster decompression of JPEGs and PNGs and techniques to make graphically intense chores drink less power.
DirectX11.1/WDM1.2
DX11.1 offers fairly innocuous changes from DX11, with the most noticeable being support for enhanced 2D graphics acceleration. DX11.1 also officially adds stereoscopic support, improved memory management, and better management of tile-based rendering for low-power applications.
Improved Scheduler
We already know that AMD says Windows 8 will give its Bulldozer cores an uptick in performance, thanks to an improved scheduler that can deal with AMD’s core design, but it’s apparently also a bit faster on Intel parts. See our performance analysis on page 32 for more info.
App Suspension
This applies more to the Metro side of the fence, but instead of Metro apps staying open and sucking up RAM, Windows 8 will suspend the applications to disk when not in use and also let the OS reclaim RAM easily. Even desktop apps, though, can be individually suspended or have components suspended when physical memory is running low.
Windows RT: What is it?
Even though Microsoft is planning to put the full version of Windows 8 onto its upcoming Surface tablet, the company realized it would also need a stripped-down version to run on ARM tablets and cell phones, so it has created Windows RT to handle those duties. Windows RT, which stands for Windows Runtime (we know, the name is horrible) is designed to run one thing and one thing only—apps from the Microsoft store. That’s all it will do, just like how an iPad or Android tablet only lets you add or remove applications. There will be no desktop, no file explorer, or any other trappings of a traditional Windows environment. Think of it this way: Imagine if Microsoft yanked Metro’s tile-based interface out of Windows 8 and created an operating system out of it; that’s Windows RT in a nutshell.
Now before you go getting your jimmies rustled, consider this: Using apps is all a tablet is designed to do. You’ll have an app for your email, web browsing, e-books, and so forth, so you should be able to accomplish most of what you can do on today’s tablets on a Windows RT device. You’ll even be able to be mildly productive, as Microsoft is bundling a free version of its ubiquitous office suite, tentatively named Office RT. And though you’ll surely be able to download some sort of media player, Windows Media Player will not be bundled with Windows RT. Hopefully, VLC will come to the rescue.
What can’t you do in Windows RT? You won’t be able to install whatever Windows software you have lying around, so put that USB key away for now. If it’s not in the Windows 8 store, you can’t install it. Good news, though—Maximum PC will have an app, so you can read all about the latest hardware anywhere you take your tablet (we won’t ask where that is).
