Toshiba X305-Q725: Quad-Core Gaming Notebook

Gaming Performance
We've chosen to focus on "reasonable" settings for the games below. That means we run Assassin's Creed and Company of Heroes in DX9 mode at maximum detail setting - DX10 reduces performance by quite a bit in AC and by a much larger amount in CoH. We run Crysis at Medium settings (for reference, High detail drops performance almost in half: 18.3FPS). The remaining games are at maximum detail settings, but without any anti-aliasing. Some titles can certainly handle higher detail settings - Fallout 3 for instance will work fine at up to 1920x1200 0xAA and maximum detail, and the same holds for other games - however, we chose to focus on 1680x1050 performance because of the X305 LCD and because that resolution offers more consistently playable performance on gaming laptops.
We do run into several situations where the detail settings create system bottlenecks, but overall the SLI 8800M GTX configuration in the Clevo laptop is clearly superior to a single 9800M GTX.
Assassin's Creed likes CPU performance almost as much as GPU power, so the lower clock speed of the Q9000 definitely has an impact here. DX10 performance is acceptable as well and helps to reduce the CPU clock speed penalty, but the overall look of the game isn't substantially changed and performance is still better in all cases under DX9. Enemy Territory: Quake Wars, Fallout 3, Mass Effect, Mirror's Edge, and Unreal Tournament 3 are all in a similar situation. The GPU advantage of the D901C does allow 1920x1200 game play in all of these titles and should increase the margin of victory, but most of these titles are hitting other bottlenecks.
Company of Heroes, Crysis, Devil May Cry 4, Far Cry 2, Oblivion, and GRID all show a greater than 50% performance advantage to the Clevo D901C notebook relative to the X305-Q725. Again, keep in mind that these two notebooks are priced quite similarly, so if you're after raw performance and don't mind a slightly heavier (and perhaps less attractive) chassis the D901C is the clear winner. The dual-core 3.0GHz CPU is a much better choice right now in gaming, though you could install up to a Q9550 if you prefer quad-core processors for non-gaming purposes.
Of all the games we tested, only one title shows any advantage to the 9800M GTX over the 8800M GTX SLI: Mirror's Edge. The advantage is further limited to situations where PhysX support is enabled; otherwise the 8800M SLI is slightly faster. We have not yet confirmed with NVIDIA whether this is a driver bug or is caused by a lack of appropriate hardware on the 8800M GPUs, but we would assume it's a driver issue. The PhysX effects do look nice at times, but even the X305 hits plenty of situations where performance can drop dramatically, and we'd recommend leaving PhysX disabled on these laptop GPUs.
Update: We discussed the Mirror's Edge PhysX issue with NVIDIA and they recommended a manual install of the PhysX drivers just to ensure they were working properly. It looks like the unified graphics/PhysX driver failed to work properly, although the system seemed to think the drivers installed properly. We uninstalled PhysX, rebooted, and installed the drivers again, and that cleared up the performance issue. As you can see, the performance of the D901C is now where you would expect, coming in 33% faster than the X305-Q725.
In the past, we've been hesitant to strongly recommend any laptops with dual GPUs, simply because the drivers were not updated frequently enough to make that a viable solution for long-term gaming pleasure. NVIDIA has now addressed the major stumbling block for SLI in a laptop, so for the mobile gamers we would definitely recommend an SLI notebook over the X305-Q725. In a best case scenario, dual GTX 280M GPUs (with the appropriate CPU) should end up providing around 50% more performance than the 8800M GTX SLI represented by the Clevo D901C, and potentially more than twice the performance of the single 9800M GTX in the X305-Q725.
Before you get too excited about the potential for mobile gaming, we do need to give a few words of caution about relative performance. The GTX 280M may be the fastest current gaming solution for notebooks, but at its core the GTX 280M is nothing more than a mobile version of the GeForce 9800 GTX. The desktop GTX 280/285 (and Radeon HD 4870) are well out of reach of anything a laptop can achieve and should remains so for some time. Short of external cards that connect via ExpressCard adapters, gamers looking for maximum performance will want to play on a desktop, and ExpressCard adapters are hardly a panacea - is anyone really going to get a laptop only to add a secondary device that requires a separate power source? I can't say the prospect is very appealing to me at any rate.

"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.Globemaster - Friday, March 13, 2009 - link
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.vj8usa - Thursday, March 12, 2009 - link
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.7Enigma - Thursday, March 12, 2009 - link
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...
