Processor Name / Brand String (Function 8000_0002h, 8000_0003h, 8000_0004h) Functions 8000_0002h, 8000_0003h, and 8000_0004h each return up to 16 ASCII bytes of the processor name in the EAX, EBX, ECX, and EDX registers.
X86_FEATURE_PNAME will be useful for displaying MSRs like AMD: MSRC001_00[35:30] Processor Name String Registers
