CPU ID information for the A0800AMT3B Athlon 800 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 AMD Athlon 800 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.
