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.
CPU-Z is more comprehensive in virtually all areas compared to the tools provided in Windows to identify various hardware components, and thus assists in identifying certain components without the need of opening the case; particularly the core revision and RAM clock rate.
An iterative refresh of Raptor Lake-S desktop processors, called the 14th generation of Intel Core, was launched on October 17, 2023. [1] [2]CPUs in bold below feature ECC memory support when paired with a motherboard based on the W680 chipset according to each respective Intel Ark product page.
