These options tell the compiler to optimize code generation for the specified x86 processor.

/G{3|4|5|6|7|B}

/G5 optimizes code for the Intel Pentium processor. It sets the value of the _M_IX86 preprocessor macro to 500.

/G6 optimizes code for the Intel Pentium Pro, Pentium II, Pentium III, and Pentium 4 processors. It sets the value of the _M_IX86 preprocessor macro to 600.

/G7 optimizes code for the Intel Pentium 4 or AMD Athlon. It sets the value of the _M_IX86 preprocessor macro to 700. Code compiled with /G7 may result in these applications running slightly slower on older processors in the Pentium family such as Pentium III.

/GB, which is the default option, is equivalent to /G6 for Visual C++ .NET; it sets the value of _M_IX86 to 600.

/G3 and /G4 optimized for 80386 and 80486 processors. The compiler accepts these options for compatibility reasons, but they have no effect.
