AMD Radeon HD 6850 reference board
AMD’s Radeon HD 6850 is a limited version of the Radeon HD 6870: two SIMD engines have been disabled. What does it mean? Simply that the Barts PRO GPU, hidden behind the VGA cooler of the HD 6850, features 960 scalar processors instead of 1120 for the HD 6870 (each SIMD engine has 80 scalar processors). The Radeon HD 6850 is priced at USD $179.
