In the test 15 years ago: ATi CrossFire was better on the second attempt

After Nvidia introduced SLI with the GeForce 6000 series, ATi had to follow suit and delivered a mediocre product with the CrossFire edition of the Radeon X800 XT. The second attempt in the form of the Radeon X1800 XT CrossFire Edition (test) succeeded better, but could not come close to two GeForce 7800 GTX 512 in terms of performance.

CrossFire only worked with an expensive special card

As with the first CrossFire generation, commissioning a multi-GPU combination was more complicated than just twoTo install graphics cards. So there were still normal Radeon models and special CrossFire editions. For multi-GPU operation, one of the CrossFire editions had to be combined with a normal Radeon - ideally with the same GPU. The CrossFire edition then acted as the master card, coordinating and merging the images into an output stream. The master card had a special external CrossFire connection to which the second card was connected via a DVI output and a proprietary cable. In addition to this unusual structure, CrossFire had another disadvantage: the Radeon X1800 XT CrossFire Edition cost significantly more at 580 euros than a conventional model at 490 euros.
