==Intel Processors==
This table shows briefly the features of each x86 CPU Intel has made. Items marked Yes are in all processors in that series, No means not (obviously), and Maybe means that some processors have it (usually later steppings).

These processors from Intel use the CPUID string "GenuineIntel".
▲Successor to the 80286, the Intel 386 is the first processor of the IA32 architecture. It has 32 bit wide registers, supports 4 kByte paging, and a flat memory model in addition to the segmented memory model of the 80286.
▲The 486 integrates a 80x87 FPU on-chip, and supports power saving functions (System Management Mode, Stop Clock, Auto Halt Powerdown).
▲The Pentium supports 4 MiB paging in addition to the usual 4 kByte paging, integrates an APIC and (in later steppings) MMX SIMD registers (single instruction, multiple data). It also supports 2-way multiprocessing.
