To obtain extended function information CPUID should be called with the most significant bit of EAX set. 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.

In Intel's more recent terminology, this is called the CPUID leaf. In assembly language, the CPUID instruction takes no parameters as CPUID implicitly uses the EAX register to determine the main category of information returned. The CPUID opcode is 0Fh, A2h (as two bytes, or A20Fh as a single word). While the CPUID instruction is specific to the x86 architecture, other architectures (like ARM) often provide on-chip registers which can be read in prescribed ways to obtain the same sorts of information provided by the x86 CPUID instruction. Because the 68000 offered an unprivileged MOVE from SR the 2 different CPUs could be told apart by a CPU error condition being triggered. This notable instruction (and state machine) change allowed the 68010 to meet the Popek and Goldberg virtualization requirements. In the Motorola 68010 the instruction MOVE from SR became privileged. These could be used to tell various CPU family members apart. In the Motorola 680x0 family - that never had a CPUID instruction of any kind - certain specific instructions required elevated privileges. Outside the x86 family, developers are mostly still required to use esoteric processes (involving instruction timing or CPU fault triggers) to determine the variations in CPU design that are present. With the introduction of the 80386 processor, EDX on reset indicated the revision but this was only readable after reset and there was no standard way for applications to read the value.

Prior to the general availability of the CPUID instruction, programmers would write esoteric machine code which exploited minor differences in CPU behavior in order to determine the processor make and model.

Température du PC : la voir avec un logiciel.

La version 1.97 de CPU-Z, parue le 25 août 2021, apporte la compatibilité avec les nouveaux composants signés Intel, AMD et Nvidia suivants (Intel Core 12e génération, cartes mères Intel Z6xx, mémoire vive DDR5, AMD Ryzen de 5e génération, cartes graphiques AMD RX 6xxx XT…). C'est un utilitaire précieux pour tous ceux qui effectuent des réglages d'optimisation de leur matériel (notamment de l'overclocking). Même s'il est doté d'une interface vieillotte, il affiche des informations très précises (modèle, architecture, nombre de cœurs, fréquence, voltage…) et propose d'effectuer quelques tests de performance sur le processeur en monotâche et en multitâche.
