The Sapphire HD 4870 X2 uses the long form factor (~ 30 cm), that we know from the HD 3870 X2. A large metal plate covers the memory chips on the back. As expected the card uses a dual slot cooler to be able to keep the two GPUs cool.
The card has two DVI ports, basically the most common output configuration these days. In case you need an analog VGA port you can use the included DVI adapter. When using an HDMI adapter (also included), you will also have access to HDMI+HDCP+Audio, which allows easy setup of a media PC. All recent ATI Radeon cards have a Realtek HD Audio device integrated inside the GPU silicon. This means that you don't have to connect any additional cabling to the graphics card for HDMI Audio. A new feature of the HD 4xxx Series is support for 7.1 HDMI audio, the older HD 3xxx cards supported only 5.1.
Here are the front and the back of the card, high-res versions are also available (front, back). If you choose to use these images for voltmods etc, please include a link back to this site or let us post your article.
