AMD released their Radeon HD 5830 Series in late February this year. The card is based on the same Cypress GPU as on the Radeon HD 5850 and HD 5870, but in order to reach their performance target, AMD has disabled some shader units as well as two ROP units. This results in a card that is roughly comparable to HD 4890 in performance, but offers all the new features from the HD 5000 Series like EyeFinity and DirectX 11.
MSI uses their well known TwinFrozr II cooler on this card, the specifications have remained the same however.
