The Radeon HD 4670 X2 was a graphics card by ATI, launched on September 10th, 2008. Built on the 55 nm process, and based on the RV730 graphics processor, in its RV730 XT variant, the card supports DirectX 10.1. Since Radeon HD 4670 X2 does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The RV730 graphics processor is an average sized chip with a die area of 146 mm² and 514 million transistors. Radeon HD 4670 X2 combines two graphics processors to increase performance. It features 320 shading units, 32 texture mapping units, and 8 ROPs, per GPU. ATI has paired 1,024 MB GDDR3 memory with the Radeon HD 4670 X2, which are connected using a 128-bit memory interface per GPU (each GPU manages 512 MB). The GPU is operating at a frequency of 750 MHz, memory is running at 700 MHz.
Being a dual-slot card, the ATI Radeon HD 4670 X2 draws power from 1x 6-pin power connector, with power draw rated at 118 W maximum. Display outputs include: 4x DVI. Radeon HD 4670 X2 is connected to the rest of the system using a PCI-Express 2.0 x16 interface.
