The Radeon HD 6850 1440SP Edition was a graphics card by AMD, launched on August 21st, 2012. Built on the 40 nm process, and based on the Cypress graphics processor, in its Cypress PRO variant, the card supports DirectX 11.2. The Cypress graphics processor is a large chip with a die area of 334 mm² and 2,154 million transistors. Unlike the fully unlocked Radeon HD 6870 1600SP Edition, which uses the same GPU but has all 1600 shaders enabled, AMD has disabled some shading units on the Radeon HD 6850 1440SP Edition to reach the product's target shader count. It features 1440 shading units, 72 texture mapping units, and 32 ROPs. AMD has paired 1,024 MB GDDR5 memory with the Radeon HD 6850 1440SP Edition, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 725 MHz, memory is running at 1000 MHz (4 Gbps effective).
Being a dual-slot card, the AMD Radeon HD 6850 1440SP Edition draws power from 2x 6-pin power connectors, with power draw rated at 151 W maximum. Display outputs include: 2x DVI, 1x HDMI 1.3a, 1x DisplayPort 1.1. Radeon HD 6850 1440SP Edition is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 241 mm in length, and features a dual-slot cooling solution.
