System States
State
Description
G0/S0
Full On
G1/S3-Cold
Suspend-to-RAM (STR). Context saved to memory (S3-Hot is not supported by the
processor).
G1/S4
Suspend-to-Disk (STD). All power lost (except wakeup on PCH).

Processor Core / Package State Support
State
Description
C0
Active mode, processor executing code
C1
AutoHALT state
C1E
AutoHALT state with lowest frequency and voltage operating point
C3
Execution cores in C3 flush their L1 instruction cache, L1 data cache, and L2 cache
to the L3 shared cache. Clocks are shut off to each core
C6
Execution cores in this state save their architectural state before removing core
voltage
C7
Execution cores in this state behave similarly to the C6 state. If all execution cores
request C7, L3 cache ways are flushed until it is cleared.
