The VIA C3 is a family of x86 central processing units for personal computers designed by Centaur Technology and sold by VIA Technologies. The different CPU cores are built following the design methodology of Centaur Technology.

In addition to x86 instructions, VIA C3 CPUs contain an undocumented Alternate Instruction Set allowing lower-level access to the CPU and in some cases privilege escalation.^[1]
