The HD4850 card is a single slot card, which is a welcome improvement for the high-end video cards. Diamond has put a skull with fangs on the front of the PCB. For those that care about the look of the video card front in a case the skull is pretty cool with a Diamond logo under it. There are capacitors on the rear of the front of the PCB as well as a single 6-pin power connector. The power requirements for a single 4850 are lower than either the GTX280 or GTX260 cards.

The rear of the card has tons of circuits for the memory chips and the mounting bracket for the ATI graphics chip. There are also stickers for the ATI Engineering Sample and the serial and part number stickers. ATI really knows how to design a clean graphics card as the card is very similar in appearance to the HD3850 from last year. The card itself is about 7.5 inches long or about as long as the HD3850.í

Input/output on the card is the standard Dual-Link DVI thatís been found on many a video card over the last few years. The use of a Dell 30Ē Widescreen LCD monitor and its 2560X1600 resolution in dual monitor mode is only possible with two Dual-Link DVI connections. You can also use HDMI connections via adapters or D-Sub connections via adapter. The HD4850 that ATI sent didnít have the adapters but the retail packaging will.

There are 8 1024 Megabit memory chips on the board bringing a total of 512MB of GDDR3 memory rated at 1GHz. GPU-Z reports the memory clock at 993MHz, a slight under-clock from ATIís claimed 1GHz memory speed on the HD4850, but not significant. With a 256-bit memory bus that brings the total memory bandwidth on the HD4850 to 63.55GB/second. The HD4870 will have GDDR5 memory with a 256-bit memory bus, but the clock speed will increase the bandwidth relative to this card.
