HIS Radeon X1800 XT ITurbo
HIS may put stickers with its logo on the cooler and the fan, but beyond that, the hardware follows ATI's reference design. The large cooler covers both the graphics processor and the memory. Warm exhaust air is pushed out of the case through the ATX shield at the back of the card. Due to the cooler's size and weight, the card takes up two expansion slots and requires secure mounting. The X1800 XT's performance is very good, which stems from the fact that HIS configures the card to run at higher clock speeds out of the box - an iTurbo sticker on the package promises a 700 MHz GPU clock and a memory speed of 1.6 GHz. The board supports Pixel Shader 3.0 and HDR rendering with simultaneous anti-aliasing. The XT version is the fastest chip of the X1800 family, and offers adequate performance for complex 3D games.
The HIS Radeon X1800 XT iTurbo features two digital DVI connectors and a video jack for S-Video or HDTV.
