Model 8/[F:8]
Processor Models and Steppings
Preliminary Information
Model 7 is the first processor manufactured in the 0.25-micron
process.
Model 7 supports six model-specific registers (MSRs).
Some important features supported by the AMD-K6-2 processor
include the 3DNow!™ instruction set and a 100-MHz processor
bus.
Model 8/[7:0] is any of eight possible model/steppings—models
8/ 0, 8/ 1, 8/ 2, 8/ 3, 8 /4, 8 /5 , 8/6 , or 8/7 . Model 8/[ 7: 0] is
manufactured in the 0.25-micron process and was the original
version of the AMD-K6-2 available as a desktop product.
Model 8/[7:0] implements the same six MSRs as the Model 7,
and the bits and fields within these six MSRs are defined
identically.
Model 8/[7:0] also implements the SYSCALL/SYSRET
Target Address Register (STAR) MSR for a total of seven
MSRs.
Model 8/[F:8] is any of eight possible model/steppings—models
8/8, 8/9, 8/A, 8/B, 8/C, 8/D, 8/E, or 8/F. Model 8/[F:8] is
manufactured in the 0.25-micron process.
Model 8/[F:8] implements the same six MSRs as the models
7 and 8/[7:0], but the bits and fields within two of these
MSRs—WHCR and EFER—are not defined identically.
Also, Model 8/[F:8] supports the STAR MSR and three
additional MSRs, for a total of ten MSRs.
