Conditional jump instructions for unsigned comparisons deal with numbers that are positive numbers only. The following table shows the condition flags used in unsigned comparison and their meanings.
| Flags | Meaning |
| ZF = 1 | equality |
| ZF = 0 | inequality |
| CF = 1 | A < B |
| CF = 0 | A > B |
Note that if number A is less than number B, there will be a borrow when B is subtracted from A. This will set the CF to 1 to indicate that there was a borrow. However, if A is greater than B, there will be no borrow and hence CF=0.
The following table shows all possible conditional jump instructions for unsigned number comparisons. The table also shows the flags condition for a jump to be taken.
| Instruction | Equivalent | Meaning (jump if) | Condition |
| JA | JNBE | Above (not below or equal) | CF = 0 and ZF = 0 |
| JAE | JNB | Above or equal (not below) | CF = 0 |
| JB | JNAE | Below (not above or equal) | CF = 1 |
| JBE | JNA | Below or equal (not above) | CF = 1 or ZF = 1 |
| JE | JZ | Equal (zero) | ZF = 1 |
| JNE | JNZ | Not equal (not zero) | ZF = 0 |
