ALU:Fetch ratio

Discussion created by ryta1203 on Apr 7, 2009

Given the RV770, is the ALU:Fetch ratio simply a matter of calculating the # of ALU Instructions / # of TEX instructions*4?

So a 4:1 ALU:TEX ratio should give an ALU:Fetch ratio of 1.00?

Is there more to it than that and if so then what?
