ATI Radeon HD5450 1GB DDR3 Graphics Card With HDMI Support

The HD 5450 is available with both 512MB and 1GB of video memory. It has a core that is clocked at 650MHz and a memory clock speed of 800MHz. Although it uses DDR3 RAM, its memory bandwidth has been limited to 64-bit, which is below par. Like the other 5000 series cards from ATI, the HD 5450 supports DirectX 11 and ATI's Eyefinity technology (that allows one card to output to multiple displays).

We got a reference card from ATI, so the design is sure to change in the hands of different manufacturers. The reference card had a small fan embedded in a heatsink over the core and three ports- VGA, HDMI and DVI. The card is slim and small and will fit into a regular cabinet without any issues. The card also does not require any additional power so there is no input port.

The card also has low power requirements -- 6.4 watts at idle and about 19 watts during regular usage. Owing to its small size, it runs silently and has no temperature issues. At full load in an open setup, the core temperature went up to 47 degrees while at idle it dropped to 35 degrees. All in all, the HD 5450 is perfectly designed to fit into an HTPC.
