AVADirect D900F Review

Performance and Benchmarks
It is almost difficult to describe how fast this notebook is in normal operation. With the Intel Core i7 975 processor, 6GB of RAM, and OCZ Vertex drives in RAID 0, the Clevo D900F blasts through any task you can think of. Installing software happens abnormally fast, boot and shutdown times are very quick, and game load times are phenomenal. Going back to my ThinkPad T60 to type this review felt like I was transitioning to my parents' 10-year-old desktop. To give you an idea of how fast this processor is, the previous "fastest" notebook in our office was an ASUS W90, scoring 23.5 seconds in wPrime when overclocked to 3.3GHz. This system finishes wPrime in an amazing 7.2 seconds! PCMark05 also increased significantly, jumping nearly 6,000 points over the ASUS W90.

HDTune had trouble reporting the full speed of the two OCZ SSDs in RAID 0, so we are also including ATTO to better show what these drives are capable of:

Gaming performance was excellent, even without SLI or CrossFire graphics. For our review we ran Call of Duty 5, Left 4 Dead, BioShock, and Crysis: Warhead. We ran each game with high detail settings (Warhead on gamer mode), in both 1280x800 and 1920x1200 resolutions. Call of Duty 5 played between 85 frames per second (FPS) and 90FPS depending on the amount of action on the screen at 1280x800 resolution, and slowed to 45-55FPS at 1920x1200. Left 4 Dead had much higher framerates, which had greater variance depending on the amount of action on screen. At 1280x800 resolution framerates varied between 200FPS and 240FPS. Switching to 1920x1200 resulted in varied speeds between 130FPS and 180FPS. Bioshock at 1280x800 showed speeds between 120FPS and 130FPS, and at 1920x1200 slowed to 66FPS to 72FPS. While those three games were fairly easy for the AVADirect D900F to handle, Crysis: Warhead proved to be more of a challenge for the D900F, running at slightly lower speeds than the ASUS W90 with CrossFire graphics. With Crysis: Warhead set to "Gamer" detail mode at 1280x800 resolution speeds ranged between 30FPS and 35FPS. At 1920x1200 framerates dropped to 17-22FPs, still kind of playable, but some tweaking would be needed for longterm gameplay. Overall while speeds would be better with two graphics cards, the D900F still proved to be more than capable for all of the games we tested on it with a single GTX 280M.

Heat and Noise
Fan noise was above almost all the other notebooks we have reviewed, having four high speed fans to cool the various internal components. The processor has two fans to itself, one for the system memory, and the forth for the graphics card. Under light use most of the fans are off or spinning very slowly. Under stressful activity such as running benchmarks or gaming the fans kick on loud enough to be heard in a decent sized room. Gaming in a classroom would be possible, if only because the battery wouldn't last long enough to annoy those around you.

Heat output is substantial while gaming, but the constant flow of air from the four cooling fans keeps the chassis temperature within reasonable levels. The pictures below show the temperature readings off various spots on the chassis after stressing the system for 15 minutes. The palmrest and keyboard are kepy fairly cool, with most of the hotter parts along the back edge near the processor and GPU. After gaming with this notebook on my lap for one night I can say I wasn't burnt, but the weight on my legs was just as bad.

Battery
I do have to admit that the first time we saw the specifications for this notebook, we bet it would probably get between 15-20 minutes when unplugged. For a notebook that consumes 75 watts at idle, the battery is more like a battery backup. With Vista set to the Balanced mode, screen brightness at 70%, and wireless active the AVADirect D900F stayed on for 1 hour and 8 minutes before abruptly turning off. Very impressive given the Core i7 975 desktop processor inside this notebook.

Conclusion
Overall the AVADirect D900F 17" gaming notebook proved to be very capable of handling modern games, even without dual graphics cards. Compared to the ASUS W90 it has slightly less graphics performance, but clearly leads in raw processing power. For encoding video or working with CAD applications the Intel Core i7 975 Extreme Edition would give you workstation level performance, without the bulk of a 30lb desktop case. While the $3,900 price seems steep, most of it comes from the processor and SSDs in our review unit. Going with a more reasonable Core i7 920 would save you nearly $800 by itself. Bottom line, if you want the most processing power out of a notebook, there is really nothing else that is faster than this with an Intel Core i7 975 Extreme Edition packed inside.

Pros:

• Intel Core i7 975 Extreme Edition inside a 17" notebook
• Smoking fast
• Very speedy SSD RAID 0
• Over and hour of battery life with a Core i7 inside

Cons:

• Chassis could use a face-lift
• Loud cooling fans
