CPU ID information for the Celeron 400 MHz
Detailed characteristics of processor's internals, including x86
instruction set extensions and individual instructions, high- and low-level
technologies, are listed below. This list was acquired from an actual
Intel Celeron 400 processor with the help of the x86 CPUID instruction. Any
discrepancies between CPUID features and official specifications are
likely due to some features being disabled in BIOS, or due to a bug in
our CPUID decoding algorithm.
Different steppings of Intel processors may also have slightly different features.
