Alienware's M17x: Mobility Radeon HD 5870 CrossFire Is A Go
By

The M17x was originally scheduled to go up against AVADirect’s Core i7-820XM notebook, but arrived with a faster Core i7-920XM processor. In order to make this a fair comparison, we held onto the system until Eurocom’s i7-940XM units arrived. Today, we get to see how well Alienware’s $3900 configuration fits between $3100 AVADirect and $4100 Eurocom competition.

Each notebook manufacturer customizes its graphics drivers to fit the unique designs of its graphics modules. Though Alienware’s driver appears older than Eurocom’s, it was still the released version available at the time of our September tests. Its parent company Dell therefore takes the credit for any effect the lower-numbered driver has on gaming performance.

Bear in mind that AMD now offers universal drivers for its mobile products, following Nvidia's example. These aren't always guaranteed to work, though. On two different occasions, we've been unable to install the GeForce drives on Clevo-based notebook models. Most recently, this was the case with the GeForce GTX 480M tested here. You're of course welcome to try these universal packages when they work, but to keep our comparison even, we used the latest driver from each system vendor at the time of writing. Note that Alienware released a newer driver after testing on its unit was completed. With that said, you'll notice that Alienware already dominates the benchmarks, so performance can only get better from here.

We also retained the desktop performance data from our first Mobility Radeon 5870 review to see if high-end gaming notebooks can reach the performance expectations of mainstream gamers. This is no trivial feat, since notebook components must be designed to generate minimum heat. The desktop platform is based on a Core i7-920 CPU, Radeon HD 5850, and 6 GB of DDR3-1333 CAS 7.
