AMD was planning to expand its Radeon HD 5800 lineup with a new member – Radeon HD 5830 at the end of this month, but according to Digitimes, AMD has to postpone it a bit later due to some unpleasant reasons.

The site claims that Radeon HD 5830 had an issue with the circuits on the board, resulting in an error on card makers’ software testing platforms.

AMD doesn’t comment on the reporte issue, but stressed that there’s no issue with its GPU-bsed cards on the market.

The release date is rumored to be February 5th, and the card will cost $199-239, taking place of Radeon HD 4890.
