ATI chose to use a single slot cooling solution with their reference HD 4670 video card. While cards like the HD 4870 X2 and GTX 280 require massive cooling solutions. The mid-range and mainstream markets are marked by the ability to run the video card in a small form factor PC or without extra external power. ATI says that their HD 4670 has a maximum TDP of 59 Watts which is less than the 75W the PCI Express slot provides to a video card and therefore the card does not need an extra power connector like many video cards do.

The card is short in comparison to the 9.5 inch video cards like the GTX 280 the card is about 6 inches long. This gives a freedom to install the card into a case that has a short distance between the mounting holes and the HDD cage. The HD 4670 has a heatsink/fan that is mounted on the graphics chip and effectively cools the graphics chip. The heatsink covers ĺ of the card length and the fan is a small one.

There are four 1024Megabit memory chips on the back of the PCB, meaning that the card has 512MB of GDDR3 memory. ATI clocked the memory chips at 1000MHz, which when combined with the 128-bit memory bus meant the HD 4670 has a memory bandwidth of 32GB/second. This pales in comparison to the memory bandwidth of the HD 3870 but is in line with the bandwidth of a sub-$80 video card like the HD 4670 is.

ATIís reference card has two Display Ports for connection to the new Display Port monitors that have replaced the HDMI monitors and DVI monitors on the market. There is also a Dual Link DVI port on the IO area to attach a DVI monitor to. You can use an adapter to run two DVI monitors with the DisplayPort ports as it is backwards compatible with dongles for Dual Link DVI. The top of the card has a pair of Crossfire bridges necessary for running two or more ATI graphics cards to improve performance.
