evo kako ih uporedjuju :
For those of you that are unfamiliar with the HD 4850, we have a single-slot cooler design; the card is roughly the same length as a 8800GT at 9.5”. The cooler is effective: we have a base layer of copper cooled by a high RPM, small fan that can push a great deal of air. Where the HD4850 fan was often forced to work at high power levels to cool that excessively hot card, the HD 4830, clocked lower, shouldn't have this problem at all, making the stock cooler completely adequate for the job.
As with the the other members of the HD 4800 family, the HD 4830 comes with a whole host of features, including: support for DirectX 10.1 and Shader Model 4.0, PCI Express 2.0, ability to be setup in a CrossFireX configuration, and as we've seen with other HD 4800's, this generation has relatively better ability to handle anti-aliasing (up to a maximum of 24x CFAA.)
