A Closer Look

As mentioned before, the heatsink is the same as on the Radeon HD 4850. It uses a big copper base to cool the GPU, memory and voltage regulation circuitry.


Two, three or four HD 4830 cards can be combined in CrossFire to improve performance or image quality.


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.
