Power Requirements

Power requirements with a laptop plugged in don't necessarily reflect power requirements when a laptop is on battery power. In particular, high-end GPUs run at lower maximum clock speeds when using the battery. Keep this in mind when looking at the following numbers. We test under idle conditions, with a 100% load placed on the CPU via Folding@Home SMP, and finally at maximum load by running FAH SMP at the same time as we loop 3DMark06 (at the native LCD resolution).

System Power Requirements

System Power Requirements

Our power measurements are with the LCD at maximum brightness, which isn't necessarily a fair way of doing things as some LCDs are much brighter than others. Unfortunately, we don't have most of the laptops around to retest. The Dell Studio XPS 16 uses 9W more power running at maximum brightness, which represents an increase in power draw of 33%. The Gateway P-7808u on the other hand only uses 3W more at maximum brightness. We can see that relative to the P-7811, idle power requirements have dropped, but tasks that place a load on the CPU - particularly on all four cores - tip the scales the other way.

Noise Levels

We also ran noise testing using an SPL meter at 24" under the same conditions as our power tests.

System Noise Levels

Gateway has clearly addressed some of the noise issues that were present on the P-7811, which never dropped below 35 dB. At idle and under low loads, the P-7808u fluctuates between almost completely silent (28 dB - or the limits of our testing equipment and environment) and around 31 dB. Once we load the CPU at 100%, noise levels increase to a range of 33-36 dB. At maximum load - or when running a modern 3D game - noise levels peak at 39 dB. Relative to other laptops, all of the noise results are good, generally placing in the upper portion of our charts. That's impressive for a laptop running a quad-core processor!

Temperatures

We didn't create any charts, but we wanted to give a quick rundown of the temperatures you might expect from the P-7808u. We placed a maximum load on the system for 60 minutes (looping 3DMark06) and then measured temperatures, so these results are something of a worst-case scenario. However, the testing environment was only 67°F, so in warmer conditions the notebook will likely run quite a bit warmer. Also note that the notebook was sitting on a hard, flat surface - you can use it on your lap, but if you block the ventilation slats temperatures may also increase.

We measured temperatures of ~45°C at the exhausts, which are the hottest spots on the chassis. Temperatures on the bottom of the laptop range from 25° to 40°, with most of the bottom measuring around 33°C. The keyboard and palm rest aren't quite as hot, ranging from 25° to 33°C with most of the keyboard staying under 30°. One of the advantages of larger notebook chassis is that they are better able to dissipate heat, we have seen quite a few smaller notebooks that run hotter than the P-7808u.

    I have a Gateway 7805u right as well but it has a Western Digital 7200 RPM 320 GB instead of the 500 GB 5400 RPM model.

    Lately in the past month or so I've had a few freezes that are exactly as you described in this article. I'm wondering if that issue is happening to a lot of other WD hard drives or is it just ours that are defective.

    I bought the 7805u a couple of months ago and I have to say that I am extremely pleased. Another advantage to that laptop is the 7200RPM hard drive as compared to the 5400RPM hard drive in this laptop that was reviewed. I don't mind the 1440x900 resolution, but I never saw the one before it. I just can compare it to other screens on laptops that I use and it seems alright. I do wish that the Fn and Ctrl keys were swapped though. I also feel that the speakers were a little lacking compared to other laptops from other companies. Some in the same price range had 4 speakers instead of 2, or a small built in sub, etc.

    I have thought about popping in a Quad whenever I feel that I'd need it, but for now I'm more than happy with the Dually that is in it.

    C'mon Gateway , pluck your arses or eyes or whatever you use to receive visual information , and see the product for what really is BEFORE you get it out the door .
    It seems that in the last few years the laptop manufacturers have a world championship :Who can shove the ****est panel in a laptop and and sell it for 1500 bucks .These displays do have a place on the market and it's called entry level or to quantify the 400-666 $ segment .
    Me ? I'll gladly send some more money to Dell for that sweet 16 . By the time I will save 1500 it will have Win.7 and ATI 4650M and it will be Purrrfect.

    What happened to the lower/higher is better in the screen benchmarks? I just got done praising you in the Dell review, and come to this one and see it's back to the old subtitles without telling us what is better/worse. Please bring it back!

    Sorry - had it on one of the charts, but it wasn't in my spreadsheet since I updated the charts directly. Consider me flogged... I'll go update the graphs and spreadsheet now.

    Hey if you want one from BB try the ASUS it looked pretty sweet. I actually bought the P-7811FX, and am reasonably happy with it. However, if I had the choice to make again I would go with a smaller lighter unit. Do not get me wrong the 7811 is great, but really how often do I game on it? The answer is not much. I use my desktop for gaming, and yes if I was on the road that may be different. But if I was on the road for work I think the time spent gamin would still be rather low. So lighter more transportable with power would be my pick now. This new unit I don't see the point much. Yes; it has a quad cpu but really what makes use of that especially that your going to run on a laptop. Even games don't make use of more than 2 cpus, then one is handling regular computer duty in the background maybe but I doubt it. I also think they should have done a 1600-1680 rez faster refresh display. So this package? Maybe if it was a full desktop replacement because I know first hand you can really forget mobility to the greatest degree.

    Re:

    [quote]drivers for the various pieces of hardware (touchpad, audio, GPU, Bluetooth, WiFi, etc.)[/quote]

    I watched my brother kill all of the processes/widgets associated with his 'drivers' for audio/video and it didn't stop the drivers from working just fine.

    I wish that it was made optional to have these widgets run when you install the drivers.

    Worst is printer drivers, I don't need 5 widgets running full time and locking up the system just to print. When will they learn?

    On topic:

    I think that for "gaming" they need to offer a 3 ghz dual core with a 98/112/128 SP card. (I am ashamed that they consider the 48 SP card a 9600GS on the desktop, and this "9800M" with the specs of a 9600GT is pitiful).

    I suppose that is nVidia's fault, but it would be nice if the laptop came with more graphics power. Although this is a decent amount of power for the money (Around $1,000 - $1,500).

    I like that they are keeping the chassis the same and focusing on what matters, the hardware.

    They should offer an OCZ or SuperTalent SSD, it would really make a noticeable difference in the computing feel for $130/209/345 more in 32/60/120GB capacities.

    I don't know if this lappy is set up for dual hard drives, but if it was you could spin down the HDD 80-95% of the time and run the OS and main apps on the SSD.

    Many of the driver widgets aren't 100% necessary and are merely system tray icons. However, rarely have I had any crashes that I would blame on touchpad, audio, keyboard, WiFi, etc. widgets. With 4GB of RAM, I just don't notice a difference between running with or without the drivers; some of the drivers are also necessary. Touchpad drivers as an example enable scrolling at the edges, I believe, along with some other extras (which you may or may not like). Another one that seems necessary for full functionality is the WiFi driver, though even there you can usually switch to letting Windows manage that connection and get rid of another app.

    As for printers... well, if all you need to do is print (as opposed to scanning, faxing, etc. with a multifunction printer), you can usually do a "driver only" install and ignore the manufacturer applications that tell you about ink levels and such. I hate those large driver suites almost as much as I despise the 5-8 processes created by most "Internet Security" suites.

    I like the Gateway® P-7805u FX Edition for $1,149.99.

    $1150 at best buy. It has a P8400 (2.26ghz dual core 3mb cache) instead of the Q9000, and a 320gb instead of 500gb HD. Otherwise, it looks identical.

    Well worth saving $550 over the 7808u!

    I also posted that before reading the final page of the review... ;)
