Introduction & Specifications

ATI has been on tear the past few months, releasing a number of new and interesting products. Since late September / early October of this year, we've been presented with Radeon X850 CrossFire and requisite CrossFire capable dual-PEG slot motherboards to go along with it, a whole series of products based on the new X1K family of GPUs, and most recently the All-In-Wonder Radeon X1800 XL. Not to mention a handful of other products we can't tell you about just yet. It seems the company is doing all it can to keep the folks talking about ATI as we head into the holiday buying season.

Today the company is introducing yet another new product, the Mobility Radeon X1600. As its name implies, the Mobility Radeon X1600 is a mobile variant of the 12-pipe Radeon X1600. We recently met with ATI in NYC to take the Mobility Radeon X1600 for a spin using a brand new notebook from Asus, the A7G. The experience turned out to be quite enjoyable.  Read on for our quick-take on ATI's new mainstream mobile GPU. You may be surprised by what you see.

The Mobility Radeon X1600

The Mobility Radeon X1600 is the first mobile GPU to come from ATI to be based on the company's recently introduced X1000 graphics technology. This part is designed for high "Performance per Watt" and is targeted for use in Performance Thin notebooks. It features ATI's new AVIVO video engine and an enhanced version of "PowerPlay", which is a specific set of featuers meant to lower power consumption and extend battery life.  We should also note that the Mobility Radeon X1600 will be fully supported in the Catalyst Mobility driver suite, so notebook users won't be left waiting for driver updates.
