oday we have in our hands a Radeon HD 2900XT board, which is of course
based on the R600 core using an 80nm design process. This version features
just 512MB of onboard GDDR3 memory clocked at 1656MHz using a 512-bit wide
memory bus. Combined with a core clock of 757MHz, the Radeon HD 2900XT can
theoretically produce a memory bandwidth of 102.4GB/s, which is greater than
that of the GeForce 8800 GTX.
