Our most attentive readers must remember that the version of drivers catalyst 6.11 makes possible to unite in regime crossFire two video card of families radeon x1950/x1900, based on the chips r580 or R580+, without the aid of master- cards or special interfaces. Strictly speaking, for these video card earlier it was possible to only get one version of work in regime crossFire: with the use of the corresponding master- card and special external cable (dongle).
The new version of driver made possible to unite in regime crossFire two slave video card (slave), and the need for the master- card was eliminated. Associates from the German site decided to show to what extent was great the passage to program CrossFire in the case of use of two video card the class radeon x1950 XTX with the resolution 1600 X 1200 in regime 4xAA/16xAF.
We united together the results of tests to one table. in Red color noted those games, in which the drop performance exceeded 10%, in green color was noted those applications, where the drop performance was minimum. On the average efficiency was reduced by 12%, but under other conditions and on another system this value can be deferent. If we are limited only to hard games the result will be good but if we look to lower hungry game so the defrence becaume smaller.in any case it is desirable to obtain system universal from the point of speed,and it has sense to spent on master- card. Especially because in the case of Radeon x1950 XTX master- card has the same frequencies and price, as the slave.
