Sweet bejeezus .. I can only dream of the driver complications here. BSN reports about an upcoming custom-design Radeon HD 5970 4GB graphics card from PowerColor that features 12 mini-DisplayPort connectors.
Engineers at TUL Corporation showed a real ingenuity by taking full usage of six display pipelines inside each Cypress chip [i.e. "Hemlock"]. Their custom HD 5970 comes with 4GB GDDR5 memory of yet unspecified clocks, but the backplate reveals PowerColor linked each and every Display pipeline with mini-Display Port connectors.
As a result, we have no less than 12 mini-DP connectors on a triple-slot graphics card with a custom cooler that enables PowerColor to significantly overclock the two Cypress GPUs and the associated 4GB of GDDR5 memory.
