CPUID should be called with EAX = 0 first, as this will store in the EAX register the highest EAX calling parameter (leaf) that the CPU implements. To obtain extended function information CPUID should be called with the most significant bit of EAX set. To determine the highest extended function calling parameter, call CPUID with EAX = 80000000h.
CPUID model numbers are 30h-3Fh. AMD Excavator Family 15h (4th-gen) – fourth-generation Bulldozer (Final optimisation). CPUID model numbers are 60h-6Fh, later updated revisions have model numbers 70h-7Fh. AMD Zen – family of microarchitectures. The successor to Bulldozer. Included in the Ryzen and Epyc CPU lines.
The CPUID is family 6 model 23 (10661h), which is between Merom and Penryn. The first Core 2 Solo processors were launched in Q3 2007 and consisted of the U2100 and U2200, which run at 1.06 and 1.2 GHz, respectively. They both feature a 533 MT/s FSB and are part of Intel's ULV family, running at only 5 W.

The instructions below are those enabled by the BMI bit in CPUID. Intel officially considers LZCNT as part of BMI, but advertises LZCNT support using the ABM CPUID feature flag. [3] BMI1 is available in AMD's Jaguar, [5] Piledriver [6] and newer processors, and in Intel's Haswell [7] and newer processors.
AMD now refers to the codename K8 processors as the Family 0Fh processors. 10h and 0Fh refer to the main result of the CPUID x86 processor instruction. In hexadecimal numbering, 0F(h) (where the h represents hexadecimal numbering) equals the decimal number 15, and 10(h) equals the decimal number 16.
The padlock capability is indicated via a CPUID instruction with EAX = 0xC0000000. If the resultant EAX >= 0xC0000001, the CPU is aware of Centaur features. An additional request with EAX = 0xC0000001 then returns PadLock support in EDX. The padlock capability can be toggled on or off with MSR 0X1107. [1]
