After the launch of NVIDIA's GeForce GTX 560 Ti, AMD made it easier for partners to release overclocked and custom-design Radeon HD 6870 graphics cards. Partners seem to be responding to this. HIS released two new custom-design Radeon HD 6870 graphics card models, based on the Barts IceQ X board design the company implemented on its HD 6850 IceQ X series. Like with the HD 6850, there's the base model that sticks to AMD reference clock speeds of 900/1050 MHz (core/memory), and a Turbo-X model that uses overclocked speeds of 975/1150 MHz. The "X" in Turbo-X denotes that it's faster than the Turbo model based on AMD's reference design board, by HIS. The cooler makes use of a slightly large aluminum fin array to which heat is conveyed by 8 mm thick nickel-plated copper heat pipes, which is centrally ventilated by a 92 mm fan. The cooler is covered by a frosty-looking shroud. Like with every other HD 6870, the card features 1120 stream processors, and connects to 1 GB of GDDR5 memory over a 256-bit wide memory interface. HIS did not give out pricing details.
