Power Requirements

Power requirements when a laptop is 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 power. 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).

Power requirements are actually pretty reasonable, considering the components in the X305-Q725. The Alienware m15x we tested last year consumes more power when its 8800M GTX is active, so the 45nm quad-core CPU at 2.0GHz uses substantially less power than the dual-core 2.8GHz X9000 in the m15x. The Gateway P-171XL also has higher power requirements (it has an X7900 CPU), and naturally the Clevo D901C is in a league of its own.

Noise Levels

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

Despite the high-end components, the X305 remains relatively quiet during operation. The large chassis has plenty of room for air circulation, and noise levels are competitive with most other notebooks. The Alienware m15x with its smaller chassis is noticeably louder, for example. Temperatures are also quite reasonable for the X305, with the bottom of the laptop measuring 25-28C under load, except for the very back edge that reached 33C in places. Exhaust temperatures at load are much warmer at up to 45C, however, so you definitely don't want to block the back of the system. While many would assume that such a large, powerful notebook would be hot enough to fry eggs, the reality is that it often runs cooler than midrange options simply because of the size of the heatsinks and fans.

    "there are users that want this sort of system, and this review is targeted at that audience. Everything clear? Good, let's continue."
    these users need professional help!

    Why? It's that hard to imagine that there are people (as me) who are travelling a lot (and working in different countries) AND who want a system, what is good for work and playing with the latest games? Travelling with a desktop PC is rather difficult...
    The truth is that I bought this rig in a refurbished (but perfect) condition for 1800USD, and for this price I think it wan't a bad deal. I wouldn't have paid 2000+USD for it either...

    I for one find the Qosmio's shape horrible, but the computer is a decent one. That Clevo smokes it on most benchmarks though, and does look nice as well. Where would you buy one online?

  • JarredWalton - Sunday, March 15, 2009 - link

    AVA Direct, Sager, and WidowPC all come to mind immediately. Eurocom is another option. The last I looked, I think Sager was actually the cheapest place for a fully equipped Clevo D901C system, but that can change at any time. Also, as I mentioned in a blog post, Clevo is coming out with the D900F that will use Core i7 desktop CPUs, so if you want more performance that's an option come ~April.

    I'm away from home for up to 220 days per year, so without my Sager (Clevo 901C) I wouldn't be able to play the games I want, ever. My limited time at home needs to be spent keeping up the house/yard and with the family. I only get to game on the road, hence the utility of these types of notebooks - it's obviously a niche, but it seems like almost everything is these days.

    How come the specs of the laptops being compared against aren't all listed? It'd be nice to know what kind of hardware you're pitting this laptop against. It'd also be nice to perhaps put the CPU/GPU of each laptop next to its name in the charts.
  • JarredWalton - Thursday, March 12, 2009 - link

    If you visit the http://www.anandtech.com/mobile/">Mobile section of our site, you'll be able to find all the specs of recently tested laptops. Most of them are in the http://www.anandtech.com/mobile/showdoc.aspx?i=339...">gaming laptop roundup, and then there's a http://www.anandtech.com/mobile/showdoc.aspx?i=341...">couple more http://www.anandtech.com/mobile/showdoc.aspx?i=343...">laptop roundups. The http://www.anandtech.com/mobile/showdoc.aspx?i=337...">Gateway P-7811 was covered in a separate article. I suppose I could try to include specs, but the problem is with this many laptops included in results the specs page would get very long. I sort of assume people that follow the mobile articles have read the previous reviews and know what to expect, but that's obviously not the case all the time.

    Nice article, but I'd like to request that you put a "higher is better" or "lower is better", or whatever determines better for each of color graphs. Only the last one says "lower is better" and I'm completely naive to these tests.
  • JarredWalton - Thursday, March 12, 2009 - link

    All of the graphs are sorted so that the better scores are at the top of the charts. As for what the terms mean, I discuss that more in depth in an article I http://www.anandtech.com/displays/showdoc.aspx?i=2...">wrote a while back. In terms of what they should be, normally I'm fine with a maximum brightness of 200 nits, and a contrast ratio of 500:1 or better.

    Color accuracy and gamut are nice to have, but if you don't do image editing or color matching it often doesn't matter. If that's the case, good black levels might be more important than raw color accuracy. Watch a movie on a display with a poor black level, and even if the colors were accurate you'd likely be somewhat annoyed by the missing blacks.

    Hope that helps some.

    That makes it much easier. Maybe just a single line (if you don't want to put Lower/Higher is better) at the beginning of the section saying they are ranked from best to worst in each of the graphs? For instance, I have a pretty good understanding of calibration from performing maintainence on my RPTV, and so things like contrast, black level, color bleed into white, etc. I get. So I get that contrast ratio should be high, but didn't necessarily think the black level number should be low (makes sense now, but not when I was first viewing the charts).

    Anyways very nice review. I especially liked that you qualified the review in the first paragraph (and reiterated throughout) stating whom this laptop is targeted at which should (hopefully) limit the regular criticisms in the comments section against this niche market. I personally don't have a use for it, but enjoy reading about the new mobile pseudo-desktops, and certainly understand their value for several different professions.

    Now go and pressure Anand for the SSD roundup! :) Please...
