The Radeon HD 5770 X2 was a graphics card by ATI, launched on October 13th, 2010. Built on the 40 nm process, and based on the Juniper graphics processor, in its Juniper XT variant, the card supports DirectX 11.2. The Juniper graphics processor is an average sized chip with a die area of 166 mm² and 1,040 million transistors. Radeon HD 5770 X2 combines two graphics processors to increase performance. It features 800 shading units, 40 texture mapping units, and 16 ROPs, per GPU. ATI has paired 2,048 MB GDDR5 memory with the Radeon HD 5770 X2, which are connected using a 128-bit memory interface per GPU (each GPU manages 1,024 MB). The GPU is operating at a frequency of 850 MHz, memory is running at 1200 MHz (4.8 Gbps effective).
Being a dual-slot card, its power draw is not exactly known. Display outputs include: 2x DVI, 1x HDMI 1.3a, 1x DisplayPort 1.1. Radeon HD 5770 X2 is connected to the rest of the system using a PCI-Express 2.0 x16 interface.
