Chinese subsidiary of ASUSTeK Computer this week unveiled the EAX1800 XT TOP graphics card that is based on the ATI RADEON X1800 XT graphics processor and features increased clock-speeds, something which was expected to be made by ATI’s add-in-board partners in an attempt to catch up with the performance of the GeForce 7800 GTX 512. 

ASUS EAX1800XT TOP clocks RADEON X1800 XT graphics processor at 650MHz and 512MB of GDDR3 memory at 1550MHz, up from default speeds of 625MHz for the visual processing unit (VPU) and 1500MHz for the memory. The board from ASUSTeK is equipped with reworked cooling system that resembles those made by Arctic Cooling company. Furthermore, to guarantee stable operation, ASUS will equip its ASUS EAX1800XT TOP with external power supply.

The manufacturer calls its development “unique” and claims that the part is going to become the world’s highest-performance RADEON X1800 XT-based solution. However, the company reveals no information about pricing and availability of the product. Earlier this week it was reported that some makers of Powered by ATI graphics cards consider overclocking the RADEON X1800 XT part from stock speeds.

RADEON X1800 XT is currently the highest-end product by ATI Technologies. The graphics processing unit features 16 pixel processors, 8 vertex processor, a brand-new architecture that supports Shader Model 3.0, high dynamic range (HDR) lighting and other innovations. Graphics cards based on the RADEON X1800 XT clock the chip at 625MHz and the memory on 1500MHz.

ATI Technologies’ RADEON X1800 XT 512MB graphics card earlier this year beat nearly all performance records in currently shipping games leaving behind NVIDIA’s flagship GeForce 7800 GTX product. However, NVIDIA Corp. recently managed to update its lineup with the GeForce 7800 GTX 512 that featured very high clock-speeds and increased amount of memory, which helped the company to dethrone ATI’s offering. Currently the GeForce 7800 GTX 512 is the fastest performing gaming solution on the planet.
