The Radeon HD 3850 X3 was a graphics card by ATI, that was never released. 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 X3 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. Radeon HD 3850 X3 combines three graphics processors to increase performance. It features 320 shading units, 16 texture mapping units, and 16 ROPs, per GPU. ATI has paired 1,536 MB GDDR3 memory with the Radeon HD 3850 X3, which are connected using a 256-bit memory interface per GPU (each GPU manages 512 MB). The GPU is operating at a frequency of 669 MHz, memory is running at 850 MHz.
Being a dual-slot card, the ATI Radeon HD 3850 X3 draws power from 1x 8-pin power connector, with power draw rated at 145 W maximum. Display outputs include: 4x DVI. Radeon HD 3850 X3 is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 292 mm in length, and features a dual-slot cooling solution.
