4.1 Some Specific Pre-loaded Use Case Results

The three use cases below are intended to span the expected range of thermal power for this device; it is possible for a use case to fall outside of this range. (And the Peak / PDN power will certainly fall outside of this range.)

Table 4-1 125°C Thermal Power
Use case Leakage [mW] Dynamic [mW] Total [mW]
ARM only (x4) 9290 5700 14990
Superset 13910 29050 42960
Compute 13450 24110 37560
Table 4-2 105°C Thermal Power
Use case Leakage [mW] Dynamic [mW] Total [mW]
ARM only (x4) 5650 5700 11350
Superset 8410 29050 37460
Compute 8150 24110 32260

Comments:

  • As noted, the exponential behavior of the leakage with junction temperature causes a significant decrease in leakage between 125°C and 105°C.
