NOTES:
1.
All power measurements taken with CMOS inputs driven to V
2.
Maximum values are measured at typical V
values not tested, but imply the maximum power one should see when running normal high power applications on most
devices. When designing a system to the typical power level, there should be a failsafe mechanism to guarantee control
of the CPU T
specification in case of statistical anomalies in the workload. This workload could cause a temporary rise
C
in the maximum power.
3.
Power specifications for 512K L2 components are PRELIMINARY. Consult your FAE.
4.
Max values are measured at typical V
with the EBL_CR_POWERON Low_Power_Enable bit set to enabled. See Model Specific Registers in Appendix C of the
Pentium® Pro Processor Developer's Manual, Volume 3: Operating System Writer's Guide (Order Number 242692).
Minimum values are guaranteed by design/characterization at minimum V
