• Single or multiple displays
• Native or non-native resolution
• Panel Self Refresh (PSR) technology
Note: Display resolution is not the only factor influencing the deepest Package C-state the
processor can get into. Device latencies, interrupt response latencies, and core C-
states are among other factors that influence the final package C-state the processor
can enter.
The following table lists display resolutions and deepest available package C-State.The
display resolutions are examples using common values for blanking and pixel rate.
Actual results will vary. The table shows the deepest possible Package C-state.System
workload, system idle, and AC or DC power also affect the deepest possible Package C-
state.
Notes:
1. All Deep states are with Display ON.
2. The deepest C-state has variance, dependent on various parameters, such software and Platform devices.
3. S-Processor Line is limited to PC8 by design.
