The Radeon HD 3850 AGP was a graphics card by ATI, launched on January 3rd, 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. Since Radeon HD 3850 AGP does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. 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 paired 512 MB GDDR3 memory with the Radeon HD 3850 AGP, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 668 MHz, memory is running at 828 MHz.
Being a single-slot card, the ATI Radeon HD 3850 AGP draws power from 1x 8-pin power connector, with power draw rated at 75 W maximum. Display outputs include: 2x DVI, 1x S-Video. Radeon HD 3850 AGP is connected to the rest of the system using an AGP 8x interface.
