Speed of Comparison operators

Question

In languages such as... well anything, both operators for < and <= (and their opposites) exist. Which would be faster, and how are they interpreted?

Answer 1

What data-type?

If y is INT_MAX, then the first expression is true no matter what x is (assuming x is the same or smaller type), while the second expression is always false.

If the answer doesn't need to be right, you can get it even faster.
