The Card

Like the HD 4890 reference design, the cooler uses two slots. Unlike the reference design it only cools the GPU and not other components. Due to the cooler design there is some airflow going to the PCB which helps with cooling.


The card has two DVI ports, the most common output configuration today. If you want to use the card with your big TV screen you can use the included HDMI adapter. In case you need an analog port you can also use the included DVI adapter.
For HDMI Audio, NVIDIA requires you to feed an external audio source, for example from your motherboard's on-board audio, to the card via SPDIF cable. AMD on the other hand has integrated a sound device inside their GPUs which is the easier solution for most users.


You may combine up to four HD 4890 cards in CrossFireX for better performance and image quality. It is also possible to combine HD 4890 cards with HD 4830/4850/4870 but you will take a performance hit because of the mismatched CrossFire configuration.


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.
