MagyarATI Mobility Radeon HD 3850 X2
The ATI Mobility Radeon HD 3850 X2 is a notebook graphics solution by AMD that consists of two Mobility Radeon HD 3850 chips in crossfire combination. Each of the two GPUs render alternating frames (called AFR) for an overall better performance than a single Mobility Radeon HD 3850. Still, the performance advantage varies from game to game depending on driver support.
According to AMD, the performance of the Mobility Radeon HD 3850 X2 should be similar to a GeForce 8800M GTX SLI setup. In our tests, the AMD solution showed better 3DMark results but had slower framerates in Bioshock and Crysis compared to the Nvidia solution. Regardless, demanding games of 2007 like Crysis (27 fps from AMD versus 36 fps from Nvidia) and Bioshock (65 fps versus 75 fps) should be playable in medium to high settings.
The features of the X2 are similar to that of a single HD 3850, including Avivo HD for decoding videos (MPEG-2, VC-1, and H.264). The current consumption should be about twice that of a single Mobility HD 3850 card, meaning only larger laptops with powerful cooling solutions can accommodate the Mobility HD 3850 X2.
