Taking It To The Limit, One More Time

AVADirect’s X7200: The GeForce GTX 485M SLI Mobile Graphics Giant
By

Gamers might be better served by Intel’s latest Sandy Bridge-based mobile processors, but Clevo’s LGA 1366-based X7200 remains the only chassis capable of supporting Nvidia’s hottest graphics modules in SLI. Capable of holding both Core i7 and Xeon processors with up to six physical cores, AVADirect equipped this workstation-class notebook with an enthusiast-class Core i7-980X Extreme.

Regular visitors will notice the recycled images. Nothing has changed about the X7200 since  last year’s introduction, though AVADirect made the thoughtful move to include a second power supply with today’s configuration.

Remembering that each of these 300 W power units is larger and heavier than a traditional facing brick, we were happy to find that the second power adapter is only required under unrealistically-extreme use scenarios (such as using FurMark and eleven threads of Prime95 simultaneously).

We’ve even discussed how the GeForce GTX 485M’s specs resemble those of an underclocked GTX 560 Ti, though we’re told it uses the older GF104 core with power-optimized BIOS and software. This power-saving design compares favorably to AMD’s Barts-based Radeon HD 6970M, at least on a specifications sheet.
