Laptop Performance

With the different power and performance characteristics of a laptop (not to mention the battery!) we’re going to break out our laptop results from the rest of our desktop data.

If you have seen our OS Mobility Explored article, where we compared laptop usage across Windows and Linux, then you should have a pretty good idea of what you’re about to see. The following is a selection of the most relevant data from that article, using Gateway’s very similar Intel and AMD power laptops: the NV5807u and NV5214u respectively.

Starting with the NV52, our Athlon 64 X2 laptop, we see some immediate advantages for Windows 7. In terms of battery life it edges out Windows XP in all situations, and clearly surpasses Vista, particularly in DVD playback. As laptops have been one of Vista’s most troublesome areas, it’s here where Microsoft needed to see some real improvement, and they have delivered.

Meanwhile performance in our limited suite of benchmarks is largely tied. Vista wins in PCMark 05 only due to higher scores in the transparent windows test (something we suspect is a product of the WDDM 1.1 memory optimizations), XP takes 3DMark 03, and Win7 takes PCMark Vantage. Our tendency is to put more weight in to PCMark Vantage, since it’s quantifying the improved laptop performance that we’ve been experiencing, but aren’t necessarily seeing in other benchmarks.

Finally we have boot and hibernation times. Microsoft has been putting some effort in to bringing down the boot times of Vista, and it shows here, although XP is too tough to beat. Hibernation is a similar story – it’s easier to resume from hibernation when you have less stuff to load.

The NV52 paints what’s probably going to be the average picture for Windows 7 on laptops. It’s as fast (if not faster) than XP and can pull off a slightly better battery life, but it’s not going to be able to beat XP in booting/hibernating.

Next we have the NV58, our Intel C2D laptop.

With battery life, we see some things similar to the AMD based NV52, and some things are different. Vista is still a loser, but Win7 doesn’t manage to build any kind of lead over XP in DVD playback, letting XP take it by a small margin. Battery life in our internet testing does go to Win7 however, once again with a small margin.

As for performance, we largely have the same results as with the NV52. Win7 wins PCMark Vantage, the test we care the most about, and pulls near-even elsewhere. 3DMark Vantage is an outlier this time, but this seems to be related to the Intel integrated graphics in this laptop.

Finally boot and hibernation times are similar to what we saw with the NV52. XP is still faster to boot and faster to return from hibernation, the benefit of an older, lighter-weight operating system. Win7 does handily beat Vista in all cases, however.

    Anandtech really needs someone that's better experienced at Linux.

    Now, I'm neither a Wintard or Freetard, but there's no balance whatsoever everytime I see them bring Ubuntu into the comparisons. I often wonder whether they broke their Linux install with the numbers they obtain.

    I don't have Win7 yet, but there's no way Ubuntu 9.04 boots that slow. I've seen it boot faster on 3 yr old laptops. I've not tried Ubuntu 9.10 yet (I'm mainly a Debian user), but from al the tests I've seen, it should blow away Win7,Vista,XP in the boot speed department.

    I agree that laptop battery life on Linux isn't as good as Windows out of the box, but a install a couple of apps (available on most distro repositories) and most people can get equal or better life on Linux. My Asus eeePC can run 8+hrs with on Arch Linux after minimal tweaking (I never got that much from XP even when the battery was brand new).

    I seriously hope AnandTech finds someone who knows Linux better (at least someone with comparable levels of knowledge that AnandTech seems to have with Windows). I've met highschool students with better Linux Know-how than this place... which is a shame, really, because other than that, I think very highly of AnandTech.

    Just my 2 cents

    Cheers~

    "I agree that laptop battery life on Linux isn't as good as Windows out of the box, but a install a couple of apps (available on most distro repositories)"
    Well the vast majority of home users don't know which apps that would be and won't find out about them

    And ArchLinux is a really sleek distribution, last time I checked the GUI wasn't even part of the standard installation. The same goes for self compiled kernels and similar things - certainly possibly but irrelevant for 99.99% of the users.


    It's the out of the box performance that's interesting for the majority (after all they didn't do anything for Windows as well), the users who enjoy playing with their PC usually already use Linux and know the advantages.

    FWIW, I worked with a "Linux Guru" -- a Senior Linux guy at a big OEM heavily involved with the ArchLinux community -- and we worked to run some additional tests on the NV52. So far, we didn't manage anything significantly better, but you can probably blame ATI's drivers as much as anything. We'll be working to expand Linux coverage (with him doing more of the work) in the future.

    Honestly, though, after spending the better part of two weeks going through numerous settings and trying to tweak ArchLinux to get significantly better battery life... well, I'm just not seeing it. I'm sure it's possible to do with the right hardware (i.e. NOT ATI!), but Linux is hardly a panacea. If you want good mobility, it's going to be tons easier for 99.999% of users to skip Linux (or get a netbook with Linux pre-installed).

    "The concern we have is that all of these auto-elevating programs are an obvious target for a local privilege escalation attack to accomplish something similar, if not the same. Imagine finding a way to make the Display control panel execute a 3rd party application with admin privileges, for example."

    Well, the same could be done in Vista... The control panel applets aren't auto-elevated, but anyone who plans on doing anything useful with them is going to elevate them anyway. So UAC in Win7 should be as effective in Win7 as it was in Vista, granting administrative privileges only to applications that really need it.

    Also, the fact that UAC is less annoying is going to be a huge security improvement on its own since fewer users are likely to turn it off. Many users are good enough with computers to figure out how to turn off UAC, but don't know enough to realize that they compromise security by doing this. They think it's condescending, always questioning the user. In fact, the prompts are there to prevent malicious software from gaining sufficient privileges to compromise the computer system, not to prevent the user from performing the tasks he/she wants. That's why Server 2008, as well as OSX and almost every Linux distribution has a similar feature.

    Of all things, multiplayer pc gaming is not mention in windows 7 (10,000 beta testers they say), and apparently Punkbuster is the defacto use for pc multiplayers and the majority of the developers.
    Consumers will like windows 7, the level of shine and sleek looking is pretty close to MacOs even themes,background on win7 is enjoyable compare to the years of dull blue windows.
    but what the crap, how long will i have to wait for a patch for this punkbuster.

    it seems to me that if Linux did what MS does with marketing, we'd have a new major Linux version every year :-) (under Linux I mean a distro like Suse or Ubuntu).

    too much hype about too little a change. basicaly they are milking $$$ out of people for performance that should have been in Vista and naming it Windows 7 ... yeah ... More like Vista SP1 that this should have been.

    anyway I don't see a reason to upgrade from XP (moving to Linux completely on my next new HW build anyway).

    Also, to the folks complaining about missing codecs, mail client and whatnot. MS is essentialy stupid. If they followed the Linux distro model, they could just sell the core OS to OEMs and let them create distributions with any applications the OEMs like. This way they get around the anti-trust issues and also get rid of supporting the distributions. but guess they are too stupid to do that.

    Yeah, because the distro vendors make so much money! Oh wait...

    In 1995 I remember talking to an older guy that worked at Radio Shack about Windows. He said he'd never upgrade from Windows 3.1 to Windows 95 because he said the memory usage was wasteful, and because even the OK buttons took up 16K of memory each.
    Over the years have I often wondered if he is still running Windows 3.1.

    Problem is, he was right...

    It's wasn't so great to watch your decked out 4mb 386 that worked well in win3.11 choke horribly just trying to load the win95 taskbar.

    Then again, it didn't really help that Microsoft was saying win95 worked fine with 4mb ram. Note fine doesn't imply being able to use more than one application at once.

    heh, no the real question is if he is still running win3.1 exclusively

    I have Vista... And from what I can see in this article, there is no point in upgrading to Win 7

    I'd upgrade for $20 or so, but anything more seems a waste of money
