AMD's HD 4830 has been a smash hit for everyone looking for best performance per dollar. The card is based on RV770, the same GPU used on the HD 4850 and HD 4870. AMD however locked the number of shading units down from 800 to 640.
While the original HD 4830 design was essentially an HD 4850 reference PCB, add in board partners quickly came out with custom designs to reduce cost. Albatron is one of the first companies to offer an even further refined design that does not require an extra PCI-Express power connector. This means that all power is supplied to the card via PCI-Express slot which has a maximum power limit of 75W. In order to keep power consumption down, Albatron has decided to go with the stock HD 4830 reference design clocks.
