Instruction Issue
Measures rates at which various shader instructions can be executed. Vector instructions are executed with 4-component vector operands.

Scalar vs Vector Instruction Issue
Compares the rate a which the card can perform ADD, SUB, MUL, and MAD instructions when operating on both scalar and 4-component vector operands. Any dual issue capability in the hardware should be apparent when performing the single component version of the instructions.
