| Notes on Intel Pentium III 650 MHz |
- The processor is usually marked as 650/256/100/1.65V or 650/256/100/1.7V,
where the last number specifies processor's core voltage. If the
processor is marked with RB80526PY650256 part number then use processor
specification number to identify processor's core voltage
- Stepping cA2 CPUs for Socket 370 were not validated for dual-processing

CPU ID information for the Pentium III 650 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 RB80526PY650256 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.
