Noise, 2D Quality
Unlike the typical coolers used on the Radeon X1800 XT and Radeon X1900 XT/XTX graphics cards, Sapphire’s Toxic liquid cooler cannot adjust its performance depending on the temperature. Users can only regulate the speed of the fan – low-speed is 2000rpm, high-speed is 2500rpm. The former setting is utterly quiet and provides enough thermal performance to cool down the board at default settings (provided that the computer case itself is properly cooled too). The latter mode can be heard, however, it is not as loud as that of the original Radeon X1900 XTX cooler working at 85% of its speed…
As we mentioned above, all the Radeon X1900-series graphics cards are generally produced at one facility, hence, they comply to quality and reliability standard that ATI Technologies defines. While there are some drawbacks with such approach, the indisputable advantage of this is very high production quality, which means that virtually all Radeon X1900-series boards should function without problems and provide exceptional quality of 2D image.
Our expectations regarding fine 2D quality were completely justified: the Toxic Radeon X1900 XTX demonstrated exceptional quality if image even in the highest resolutions that our Dell P1130 and P1110 monitors support – 1800x1440@75Hz.
Overclocking, Power Consumption
Given that the Sapphire Toxic liquid-cooled Radeon X1900 XTX already comes pre-overclocked, we did not have hopes for any further potential to run at even higher speeds. Still, we attempted to add some more muscle to the board. Unfortunately, just as expected, the part did not show any significant speed boost – about 10MHz per core and something like 20MHz for the memory is not a truly good result.
However, we should point out that we had an early revision of the Sapphire Toxic liquid-cooled Radeon X1900 XTX, therefore, retail versions may overclock better, especially if end-user turns the turbine to the max and increases voltage settings a bit.
ATI Radeon X1900 XTX is widely known as the “champion” when it comes to power: this board consumes about 120W and if you are planning to acquire it, you have to ensure that you have a quality power supply unit.
