Radeon HD 4830 Has 640SP

Seems like Radeon HD 4830 will have 640 stream processors instead of the 480 as we learned previously. It comes with 256-bit memory interface with 512MB GDDR3 memories. Since AIB partners are free to design their own cards therefore we should be seeing different card solutions with different clocks and memory sizes/types from each makers. Radeon HD 4830 i is targeted primarilyat Nvidia GeForce 9800 GT with a less than US$ 150 price tag.
