The graphics card with single-slot cooler clocks the processor at 575MHz, and carries 256MB of 1.20GHz GDDR3 memory. Based on the picture submitted by PowerColor, the Radeon X1900 GT is made using print-circuit boards for the Radeon X1800 XT or the X1800 XL with lower number of elements compared to the Radeon X1900-series boards.

The initial plan was to ship approximately 25 thousand Radeon X1900 GT units to computer makers worldwide. The relatively low amount of boards to be available could be dictated by the fact that some of the Radeon X1900 GT parts should utilize R580 chips that do not have 48 pixel processors fully-functional, whereas ATI did not have enough “partly-faulty” chips and had to use fully-fledged R580 chips – which could be sold for $500 per card – with some of execution units halted. It is unclear whether with retail availability of the Radeon X1900 GT the number of units to be produced will remain the same, or will increase.
