![]() Since the memory is clocked at 1.15 GHz, and utilizes 256 bit interface, the effective memory bandwidth is 147.2 GB/s. The Radeon HD 6870 Black Edition embeds 1 GB of GDDR5 memory. It also has 1120 stream processors, 32 color ROPs, and 56 texture units. You can find other tests with FurMark HERE and HERE. The card has graphics clocked at 940 MHz. We can all the same mention the OpenGL 4 tessellation score with TessMark (normal tessellation mode: X16): Some HD 6850 come with 1120 shader processors enabled…įor performances (OpenGL and Direct3D) just jump to the Radeon HD 6870 article. GPU Computing: OpenCL 1.0, DirectCompute 11.Memory: 1024MB GDDR5 1000MHz real speed (4000MHz effective), 256-bit (see HERE) for memory speed details).GPU: Barts PRO 775MHz, 1.7 billion transistors, TSMC 40nm. ![]() Here are the official specifications of the HD 6850: The Radeon HD 6850 is priced at USD $179. 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). AMD’s Radeon HD 6850 is a limited version of the Radeon HD 6870: two SIMD engines have been disabled. ![]()
