To test claims of faster booting and lower memory usage in Windows 8, I installed a fresh copy of Windows 7 on each of three different computers of varying vintages—a Dell Latitude E6410 with 8GB of RAM and an SSD, a Dell Latitude D620 with 2GB of RAM and an HDD, and a lowly netbook with 1GB of RAM and an HDD. More complete specs for these systems can be found on this page, in which I discuss the computers on which I’ve been running Windows 8. Each computer had the most recent drivers for all of its hardware installed.

Startup time is defined as the amount of time between when the power button is pressed and when the Windows login screen is ready for input. POST time is defined as the amount of time between when the power button is pressed and when the “Starting Windows” boot screen first appears. After measuring all times in Windows 7, I reformatted the hard drives, installed Windows 8 and any needed drivers, and measured boot times in the same way.

Windows Cold Boot Times

Microsoft claimed that Windows 8 featured improved boot times, and that claim is definitely true—boot times vs. Windows 7 are down across the board. These reductions are due to some architectural changes that Microsoft has made—a Windows 7 shutdown would completely purge the OS and all running programs and user sessions from memory and then re-load a fresh copy at next boot. Windows 8 unloads the user session and running programs from memory, but saves the core OS to disk from RAM as it would do if the OS were hibernating. The result is a much faster startup time all around, even on mechanical HDDs. If, for whatever reason, your system doesn’t support hibernation (or if you’ve turned it off), these boot time advantages will evaporate.

But what's that, you say? How is a netbook that barely meets the minimum system requirements booting more quickly than a late-model Dell Latitude? Perhaps these numbers will clear things up:

Test System POST Times

This is one of the instances where hardware designed for Windows 8 will probably have an advantage over older hardware that has been upgraded—as you can see here, a computer’s time to POST is a larger than ever percentage of total boot time. Thanks to its newer hardware and SSD, the Latitude E6410 only takes four or five seconds (!) to boot to the login screen in Windows 8, but its nearly 22 second POST time means that both the Latitude D620 and the lowly netbook are ready to use more quickly. Systems designed for Windows 8, especially those configured to use UEFI instead of legacy BIOSes, can have drastically shorter POST times, and new computers equipped with SSDs may well go from powered-off to ready-for-input in just a few seconds.

To test claims of reduced memory usage, I took the same machines and let them idle at the desktop with only the Task Manager running. Both the Windows 7 and Windows 8 installs used the same drivers, so any background processes running on one OS were also running on the other OS.

Memory Usage

We see marginally lower base memory usage in Windows 8 compared to Windows 7 on the two Dell laptops by a noticeable but not staggering amount. The netbook, with its 1GB of RAM, sees about the same base memory usage under both operating systems—because of the extra caching and preloading that's going on under the hood, my experience has been that Windows 6.x's memory usage increases when you give it more RAM to work with. That computers with 2GB and 8GB of RAM would have a higher base memory usage than a machine with 1GB of RAM shouldn't be surprising.

These slight savings won’t keep you from needing to upgrade your RAM if you’ve been thinking about it, but it’s impressive that Microsoft has been able to hold steady or slightly decrease the amount of RAM used in spite of the additional features (and remember, since Windows 8 includes both anti-virus and anti-spyware protection built in, these numbers should look even better after an install of Microsoft Security Essentials or another anti-virus package on the Windows 7 machines).

    Yes it will.

    As Andrew said it will run fine on AMD hardware. I've been running the Developer Preview since September on my Phenom II X6 1100T & Radeon 6970, which I then (side-graded?) to an FX-8150, and then upgraded to the Consumer Preview.

    The only BSOD or crash I've ever had was when I tried to install the AMD USB filter driver under the developer preview - it warned me the driver was unlikely to work, I gave it my usual "I know better than you" and promptly got to see the fancy new Win8 BSOD screen.

    Haters gonna hate man. I'm sorry people have blown up on you for no reason.
  • Andrew.a.cunningham - Tuesday, March 13, 2012 - link

    It's cool - mostly I'm just confused about it, but the constructive comments have far outnumbered the trollish ones at this point. :-)

    Either way, I'm working on getting an AMD system for future use.

    Don't worry about it. He tested enough systems, and you can make a guess as where AMD would stand in those systems. I agree that a lot of people use AMD - it's all I buy for friends and family as the Microcenter deals are too hard to pass up. I don't think it effects the review at all - Windows 8 won't look any different on an AMD system.

    I too just created an account today. Ive been reading anandtech for a while now but havent bothered to make an account. But today i had too.

    There is absolutely no reason for you or anyone else to blow up on Andrew for only using intel systems for this review, a review of a preview at that, when his reasoning was extremely simple. He just didnt have an AMD system on hand. Who are you to blame anyone of being biased when you know nothing about them.

    I'm disappointed that i didn't read these comments until today (monday) or i would have commented sooner. I was so pissed off after reading these comments i messed up two different captcha's when making my account just now. I hope you're just saying this to try to feel some sense of superiority over someone who actually has a job on a real tech site, and not because you actually think andrew is that biased toward intel. Because that's just stupid.

    Thanks. :-)

    I don't see how anyone who's spent so much as five minutes along with Windows 8 on a normal desktop computer--let alone hours--could say that the new start menu system is even remotely an improvement on the old system. It is unequivocally worse. It creates a jarring, disjointed experience, with an interface that is less versatile and consequently makes simple tasks more difficult.

    Why must I jump through hoops just to shut my computer down? Or if I'm not sure Windows considers what I'm looking for an app or a setting, why do I have to do multiple searches, when previous versions of Windows would show me all the possibilities?

    It would be so simple for Microsoft to solve all these numerous (yet minor) annoyances: give a legacy desktop option. Just one little checkbox to where a user can specify that they would rather boot into the desktop than the Metro BS, and to restore the start menu to a Windows 7 state. You can't tell me that would be difficult in the least, but MS would rather be obstinate jerks, trying to force users into a "new experience" that they don't want, don't like, and that actively works to make their workflow more inefficient.

    Change isn't a bad thing, but only when that change is an improvement. Going from the XP start menu to Vista's added functionality and made things easier. Going from 7 to 8, though, is a step backward, and users shouldn't have to suffer just because MS wants to push their little pet project.

    I'm glad I'm not the only one. I find myself having to move left to right across the screen to do stuff that a simple rightclick/clcik would do previously.

    Having to use the keyboard for stuff that a mouse click did previously as I cant work out if there is a mouse equivalent or if it exists at all.

    No visual clues as to how to use it. Just clicking on all the empty space in the hope something useful happens.

    I see one thing makes the desktop bit shrink to a small size in the middle of the screen. I have no idea what that is for.

    I think Metro is fine for folks that have never used a computer for real day to day office work that brings home the bacon. You know the types.

    Assuming MS doesn't reverse course on their "Abandon the Start Menu" decision, hopefully by time the RTM version rolls out, they will include some sort of tutorial the first time you switch into desktop mode.

    Really, though, the whole ordeal reminds me of when Apple made the iPod Shuffle without any buttons on the physical device, and insisted on making users learn a sort of Morse code on the remote to accomplish anything. You could argue that a single button makes things "simplified," but that doesn't prevent it from being an inane, unproductive input method.
