The CPU power states C0–C3 are defined as follows: C0 is the operating state. C1 (often known as Halt) is a state where the processor is not executing instructions, but can return to an executing state essentially instantaneously. All ACPI-conformant processors must support this power state.
POWER9, 64-bit, PowerNV 24 cores of 4 way SMT/core, PowerVM 12 cores of 8 way SMT/core, follows the Power ISA 3.0. Introduced in 2016. Introduced in 2016. Power10 , 64-bit, 15 SMT8 or 30 SMT4 cores, will follow the Power ISA 3.1.
Yellow Dog Linux, full support for 32/64-bit; PS3; Void Linux, support in third-party fork [27] for 32-bit and 64-bit (big-endian and little-endian) Solaris 2.5.1 PowerPC edition on the PReP platform OpenSolaris, experimental [28] [29] JavaOS; Windows NT 3.5, [30] 3.51 and 4.0; ReactOS, PowerPC port no longer under active development [31]
Advanced power management (APM) is a technical standard for power management developed by Intel and Microsoft and released in 1992 [1] which enables an operating system running an IBM-compatible personal computer to work with the BIOS (part of the computer's firmware) to achieve power management.
The PowerPC 970 ("G5") was the first 64-bit Mac processor. The PowerPC 970MP was the first dual-core Mac processor and the first to be found in a quad-core configuration. It was also the first Mac processor with partitioning and virtualization capabilities. Apple only used three variants of the G5, and soon moved entirely onto Intel architecture.

The power management for microprocessors can be done over the whole processor, or in specific components, such as cache memory and main memory. With dynamic voltage scaling and dynamic frequency scaling , the CPU core voltage , clock rate , or both, can be altered to decrease power consumption at the price of potentially lower performance.
82385 - High Performance 32-Bit Cache Controller. [23] This chipset was introduced in February 1987. It was available for 20 MHz version. [26] There is 33 MHz version available for the 386DX processor. [27] Paired with 33 MHz 386 CPU and 64-Kbyte memory subsystem, it performed up to 7.8 MIPS. [28] There is 82385SX version for the 386SX ...
