Rumors are that AMD is suffering from yield issues in the 40nm process used in the Radeon HD4770 chips, and the backstock of the HD4830 is beginning to dwindle. What’s AMD going to do to remain profitable? Apparently they’re going to shrink the 4830 card, add in GDDR5 memory, and re-release it as the Radeon HD4730, which will use the more mature 55nm process.
It’s an unusual move, definately meant to work in the short term.
