Testing:

With the HD 4830 being based off of the HD 4800 series RV770 core I am quite excited on seeing what this bad boy can do. To gauge the scores on an average I will be including a slew of cards currently on the market so you can see where it stands among the mid to high range video cards. To eliminate any variables, all hardware will be ran at stock speeds, timings, and voltage so there will be no interference in the numbers. All of the hardware will remain the same for each video card tested to keep the scores fair.

PowerColor HD 4830 670/995

Wow was I surprised when I got to overclocking this baby. She took everything I threw at her and begged for more. Using the Catalyst Control Center I was able to increase the core speed from 575MHz to a whopping 670MHz; almost 100MHz increase. Not bad for a little card like this. As expected the memory came close to the rated 1GHz limit topping off at 995MHz ( 1990MHz Effective ). This card easily reached these speeds by upping them in 5Mhz increments each until it became unstable and then I backed off 1MHz at a time until I had no more issues or display problems.
