CPU ID information for the Pentium III 733 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 Pentium III 733 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.

Our CPUID database contains 2 records for this microprocessor. See all submitted records.
