The HD4870 from Visiontek is a dual slot cooled card, meaning that the card takes two adjacent slots on the motherboard to install, a PCI Express Generation 2.0 x 16 slots, and the slot next to it. Visiontek uses the reference cooler which has the RADEON HD 4870 name, 512MB, and the company logo on the front. A 49-fin fan covers the rear of the front of the PCB, blowing air through the card out the grill of the front of the card.

The HD4870 is a PCI Express Generation 2.0 card. This means that the card has about twice the bandwidth available to it from the motherboard chipset to the card at about 8GB/second when an x16 slot is used. PCI Express 1.0 allowed about 4GB/Second bandwidth between the card and the motherboard chipset.

ATI has chosen to clock their reference 4870 at 1.8GHz for the memory with a 256-bit memory bus interface. Double Data Rate memory bandwidth is effectively doubled, meaning that the effective speed is 3.6GHz. The total memory bandwidth on the HD4870 card is 115.2GB/second, which is much higher than the HD4850 which uses 256-bit bus with only 1GHz speed.
