HIS Radeon HD 4890 1GB and Diamond Radeon HD 4890 1GB XOC
The above-discussed GeForce GTS 250 cards cost about the same money as the Radeon HD 4850. The Radeon HD 4870 and GeForce GTX 260 are more expensive. These three graphics card models have been discussed in our earlier reviews, so I will proceed right to the next step: Radeon HD 4890 1GB.
This model is represented by two products in this review: one more card from HIS and a card from Diamond. Both come in small but nice-looking boxes.
Inside the cardboard wrapper there are smaller boxes that contain the cards and accessories.
The HIS card comes without the exclusive flashlight-screwdriver the manufacturer used to include with its products before. There are no games enclosed with either card.
These products are exact copies of the reference card and only differ from it with the stickers on the coolers.
Each card measures 244x100x35mm and has a dual-slot cooling system.
These Radeon HD 4890 from HIS and Diamond are equipped with a PCI Express x16 version 2.0 interface, two dual-link DVI-I ports with support for high resolutions, and an S-Video output. There is a grid in the mounting bracket for the hot air to leave the system case.
The connectors for CrossFireX mode are still at the top of the PCB (it would be hard to place them anywhere else, though).
