The X1800 Crossfire Edition is based upon ATI's R520 chipset. This has 16 Pixel Shader Processors compared to 48 on the X1900 card, and 8 Vertex Shader Pipelines. The X1800 was the first ATI card to use their 90 nanometer process, and had 321 million transistors. The clock speed of the X1800 Crossfire edition is 621MHz for the core and 1494MHz for the memory.

X1800XT TOP card
ASUS's X1800XT TOP card was provided last year for Crossfire testing. Unfortunately, due to us not having a Crossfire Edition Master card, the review was delayed till this year. ASUS's card is overclocked above the standard X1800XT and has an external power brick. For purposes of testing, I used the ASUS X1800XT TOP card with an ATI Crossfire Edition Master card.

Installing the ASUS X1800XT TOP card in Crossfire mode is simple. Install the master card into the indicated slot on the motherboard, install the ASUS card into the other. After hooking up the Crossfire cable to both cards, and power cords, turn on the computer. Upon installing the Catalyst drivers off ATI's website, an option for Crossfire mode will appear on the menu. Check the check mark, enable Crossfire and you're good to go.
