A Closer Look

Powercolor's heatsink does not use any fancy heatpipes or copper, the temperatures are still lower than the AMD reference design.


Two, three or four HD 4830 cards can be combined in CrossFire to improve performance or image quality. You can also combine the HD 4830 with the HD 4850 (I tested it), but then the HD 4850 will be slowed down to match the speed of the HD 4830.


A single 6-pin PCI-Express power connector is required to power the card.


The GDDR3 memory chips are made by Qimonda (formerly Infineon) and carry the model number HYB18H512321BF-10. With a latency of 1.0 ns they should be good for at least 1000 MHz.


AMD uses their RV770 GPU on the Radeon HD 4830. Compared to the "regular" GPU, the number of shaders and texture unit is reduced via a locking mechanism. The GPU silicon remains the same for this change.
