AMD R600 board is a monster
First of all, you need to know that this PCB (Printed Circuit Board) is the most expensive one that DAAMIT has ever ordered. It's a complex 12-layer monster with certain manufacturing novelties used in order to support the requirements of the R600 chip, most notably the 512-bit memory controller and the distribution of power to the components.
The memory chips are arranged in a similar manner as on the G80, but each memory chip has its own 32-bit wide physical connection to the chip's RingBus memory interface. Memory bandwidth will therefore range from anywhere between 115 (GDDR3 at 8800GTX-style 900MHz in DDR mode - 1.8GHz) and 140.1GB/s (GDDR4 at 1.1GHz DDR, or 2.2GHz in marketingspeak). |
