GeForce 7600GT, Continued
Lastly, the die is 125 sqmm. This makes it 71-sqmm smaller that the 7900GTX and 24-sqmm smaller than the ATI RV530. This smaller package does away with the requirement of an additional power connection.
The chart below shows the core differences between the new- and last-generation architecture.
