The Radeon HD 3830 was a graphics card by ATI, launched in April 2008. Built on the 55 nm process, and based on the RV670 graphics processor, in its RV670 PRO variant, the card supports DirectX 10.1. The RV670 graphics processor is an average sized chip with a die area of 192 mm² and 666 million transistors. It features 320 shading units, 16 texture mapping units and 16 ROPs. ATI has placed 256 MB GDDR3 memory on the card, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 668 MHz, memory is running at 828 MHz.
Being a dual-slot card, the ATI Radeon HD 3830 draws power from 1x 6-pin power connectors, with power draw rated at 75 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Radeon HD 3830 is connected to the rest of the system using a PCI-Express 2.0 x16 interface.
