The ATI R600:
What is it that makes this video card tick? Let's break down the components and find out. First we'll start with the rear bracket that secures the heatsink and fan to the board. It's of metal construction for a sturdy foundation.
The heatsink and fan cover is made of a Lexan plastic which screws into the plate that surrounds the heatsink and holds the fan.
The plate which holds the heatsink and fan in place is made of plastic.
The heatsink is pure copper and also has a pipe system to vent hot air away from the chip.
The backbone of the whole system is the ATI R600 Chip. it is 80nm and has 700 million transistors. For more on the R600, please remember to read our specifications section.
Finally there are the memory chips.
