Gateway NV58 (Intel) - Futuremark

Performing a few quick system/graphics benchmarks, let's see if there are any major differences between the Windows operating systems. As always, Vantage requires Vista/Win7 so XP gets a "0" on those tests (which is not to say XP fails - it's just the way we have to do things with our graphing engine).

Gateway NV58 Futuremark Performance

The 3DMark results aren't quite as close this time, other than 3DMark05. XP trails in 3DMark06 by around 19%, and Vista leads in 3DMark03 by about 13%. Unlike the NV52, 3DMark Vantage scores almost twice as high as Vista with Windows 7 on the NV58, so perhaps Intel has invested some extra effort into improving their Windows 7 drivers. Of course, 3DMark Vantage barely worked on the NV58 and Vista, where it failed repeatedly to run anything other than the Entry test suite, so improving on that result shouldn't be too hard. Hopefully it's not simply a case of app detection and driver hacks to improve the score, though it looks rather suspicious. Anyway, we all know 3DMark isn't a game and as such you should take the above results with a grain of salt. PCMark05 also has XP in last place, but the 2D Transparency test again skews the results, so look at the table below. Meanwhile, PCMark Vantage again shows Windows 7 being Windows Vista, this time by 15%.

HDD XP Startup (MB/s) 9.661 8.158 8.14

Memory Latency (MAccesses/s) 8.207 8.108 8.012

As with the NV52, the PCMark05 composite score muddies the waters and makes it look like Vista is superior to XP and Windows 7. This time, 2D Transparency is 32 times faster on Vista than XP and 17 times faster on Windows 7. That score alone is able to drop Windows XP to the back of the pack in overall score, but it leads in virtually every other category. The 3D Pixel Shaders result favors Windows 7 and Vista over XP and Win7 is the fastest, potentially giving support to the idea that Intel has improved their graphics drivers under Win7. On the other hand, Win7 trails in the Physics and 3D test by 38% relative to XP and 51% compared to Vista. Maybe the 3DMark Vantage result is just a case of driver optimizations.

As before, we calculated our own composite score among the operating systems, with and without the 2D Transparency result. We didn't weight any of the tests, and our average of the 11 tests puts Vista at 278% faster than XP and Win7 139% faster. Remove the 2D Transparency score from the average and XP suddenly jumps up to 11% faster than both Vista and 7, which end up in a tie. We're not trying to say that 2D Transparency is worthless, but it does account for deflated PCMark05 scores on Windows XP.

Gateway NV58 PCMark Vantage Breakdown
  Vista SP2 Win7 RTM
PCMark Vantage 3397 3911
Memory 1896 2237
TV and Movies 2482 2613
Gaming 1999 1998
Music 2851 4206
Communications 3774 4033
Productivity 3039 3156
HDD Test 2643 2867

PCMark Vantage gives the lead to Win7 by 15%, with individual results ranging from a tie in Gaming to a 48% lead in Music. Unlike the NV52, the TV and Movies suite doesn't show a major difference, nor do the Communications and Productivity suites, but HDD and Memory show a larger benefit to Win7 on the NV58. Ultimately, PCMark Vantage still confirms that Windows 7 is faster overall than Vista, even if the only area that appears to benefit by a large amount (i.e. regardless of platform or hardware) is the Music suite.

    I'm not sure if it's possible at this point, but if you can, would it be possible to try out a copy of the 9.10 Alphas that are available? They should hopefully fix some of the intel driver regressions.

    Also, as an FYI/diagnostic, there's a CPU speed applet that is available in Gnome. Right click the top panel, select 'add to panel', and then somewhere there's a cpu speed monitor. That can be used to see if SpeedStep/Cool'n'Quiet are working correctly. You can even take it a step further, and change the permissions of the applet to allow you to change which CPU speed governor is active if you find that the CPU is running at full speed constantly.

    By the way, you should not use external sites during your test. The fact that you said "perhaps a Flash ad server was temporarily down" means you are doing it wrong.

    Different flash ads could be very different in CPU usage.

    What you should do is snapshot/save the complete pages loaded from the websites you want, put them on a standardized webserver under your control, and then get the browsers to load the pages from that webserver. Disconnect the test network from the internet to prove that the page loads up fine without requiring external connections (css etc). You may need to include a test DNS server that fakes the replies, or stick to using IP addresses to access the test pages e.g. http://10.5.5.1/site1/testpage1.html">http://10.5.5.1/site1/testpage1.html http://10.5.5.1/site2/testpage1.html">http://10.5.5.1/site2/testpage1.html http://10.5.5.1/site3/testpage1.html">http://10.5.5.1/site3/testpage1.html

    Once you have standardized on a set of pages, this means you don't have to redo the tests on all computers weeks/months later when you have another laptop to test. You only need to test the new device - since the pages are the same. Don't change the webserver too much either (but given the low loads it's unlikely to affect things much - unless it's really really slow).

    Already in progress, after my round two Internet testing still proved too variable. As noted elsewhere, though, I want the content to be as close to realistic as possible. Law of averages says that most of the ads will balance out. It's also possible my home wireless phone knocked out my home WiFi a few times, which would mean several minutes (more?) of non-traffic. Many times I'm not around while letting the battery drain, since that's a bit of a waste of time.

    I need a new home phone for sure, though. The 2.4GHz model I bought several years back wreaks havoc on my 802.11n network.

    You need a home phone at all?
  • JarredWalton - Wednesday, September 23, 2009 - link

    Babysitters might need something to call us, yeah. Could leave a cell with them I suppose, but I also use it for business/fax.

    I highly recommend the Uniden DECT6.0 models. The kit I got about 6 months ago to replace crappy old units was ~$110 for 3 units. Additional units (if your manion requires :) can be added easily to the setup for another $30-40. No wireless issues whatsoever. And it's the first phone I've been able to use out to my curb without issues (brick exterior with plaster walls = bad signal). The only gripe I have is there doesn't appear to be a way to change the caller ID name when it comes in. You can program your own numbers in, but when you receive a call it always shows only how caller ID recognizes it.

    Got mine from the egg.

    on my Atom based laptop. Flash is mostly used for annoying advertising. And it eats CPU, makes the budy slow.
    Booo to flash...
    M.

    If Adobe merely added a button to freeze all Flash animations or even just freeze all Flash in non-active tabs, then like a hundred power plants could have been scraped…
  • JarredWalton - Tuesday, September 22, 2009 - link

    Which is what FlashBlock does. :) Of course, Linux browsers by default don't normally auto-play Flash I don't think. I enabled that with Firefox and then used FlashBlock to stop it, just for an "apples-to-unoptimized-apples" comparison to Vista.
  • bigboxes - Monday, September 21, 2009 - link

    Whatever. I use adblock plus and see few ads. Flash, however, is a part of how we view the internet. It's a part of our experience. If you want a text only internet please feel free to step back in the wayback machine to 1988.
