Radeon X1950 XTX has just been launched and we’re working hard on our review of this card that should appear soon. Until then our overclocking guru and graphics card editor Marcus “Kinc” Hultin has been playing around with ATI’s latest graphics card but also taken the time to set a new world record with ATI’s previous flagship Radeon X1900XTX. Kinc has with a completely air-cooled system reached over 16 000 points with 3Dmark05 using ATI’s reference card of Radeon X1950 XTX and this together with Intel’s X6800 processor clocked at 3.94GHz, up from 2.93GHz (on air!) while Radeon X1950 XTX has been pushed to 776MHz GPU and 2280MHz memory. Also this using just air cooling!
The bottleneck is not the hardware despite the cooling but the overclocking tools that are available for the X1950 XTX that doesn’t allow any higher graphics memory frequencies. But a final score of 15 917 points with 3Dmark05 has to be considered very impressive as it is all being cooled by air.
X1950 XTX – 16 088 points with 3Dmark05
When the OC tools became a bottleneck for ATI’s new flagship Kinc turned to ATI’s previous flagship, Radeon X1900XTX, using some more extreme methods. An ASUS-made Radeon X1900XTX graphics card got its cooler exchanged for a two-stage compressor cooler which forced it down to -80°C and moved the frequencies up to a whopping 909MHz GPU and 1800MHz memory. Intel’s X6800 processor was equipped with a similar two-stage setup with temperatures down to -100°C and this resulted in a frequency of 4.69GHz using a 11x multiplier and a 1706MHz processor bus. This monster system scored 17634 points with 3Dmark05 which is a new world record for single-GPU systems and shows that the X1900 series still has a lot to offer. More detailed information about the world record systems and both overclocking projects can be found below, more information about X1950 XTX will published with our review soon.
