Comparision of Excel sheets

I just want to ask for your help by providing me codes / references to compare the data in two worksheet, which it means to compare the data in sheet 1 and sheet 2 and display the comparing result in sheet 3, all the worksheet was in one same workbook. As the below code displaying the values for matching rows but i want the output if different values exist for same fileds in two sheets.

Sub compare()
Dim LastRow_1 As Integer
Dim LastCol_1 As Integer
Dim Data_1 As Range
Dim LastRow_2 As Integer
Dim LastCol_2 As Integer
Dim Data_2 As Range
Dim Sh_1 As Worksheet
Dim Sh_2 As Worksheet
Dim X As Long
Dim Y As Long
Dim C_1 As Range
Dim C_2 As Range
Dim C1 As Range
Dim C2 As Range

Set Sh_1 = ActiveWorkbook.Sheets("Master")
Set Sh_2 = ActiveWorkbook.Sheets("Inventory")
LastRow_1 = Sh_1.Range("A500").End(xlUp).Row
LastCol_1 = Sh_1.Range("A500").End(xlToLeft).Column
Set Data_1 = Sh_1.Range("A2").Resize(LastRow_1, LastCol_1)
LastRow_2 = Sh_2.Range("A500").End(xlUp).Row
LastCol_2 = Sh_2.Range("A500").End(xlToLeft).Column
Set Data_2 = Sh_2.Range("A2").Resize(LastRow_2, LastCol_2)
For Each C_1 In Data_1
For Each C_2 In Data_2
If Data_1 = Data_2 Then
If C_2 = C_1 Then
'found a cell on sheet2 that matched cell in sheet1
'now do what you need to do
C_1.EntireRow.Copy Destination:=Worksheets("New_Master").Range("A500").End(xlUp).Offset(1, 0)
C_2.EntireRow.Copy Destination:=Worksheets("New_Master").Range("A500").End(xlUp).Offset(1, 0)
End If
Next C_2
Next C_1
End Sub
