An operating system running on PowerPC 615 could either choose to execute 32-bit or 64-bit PowerPC instructions, 32-bit x86 instructions or a mix of three. Mixing instructions would involve a context switch in the CPU with a small overhead. The only operating systems that supported the 615 were Minix and a special development version of OS/2. [38]
POWER8, 64-bit, hex or twelve core, 8 way SMT/core, 5.0 GHz, follows the Power ISA 2.07. Introduced in 2014. 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. Power10, 64-bit, 15 SMT8 or 30 SMT4 cores, will follow the Power ISA 3.1. Introduced in 2021.

The 603 series had a 32-bit FPU, which took two clock cycles to accomplish 64-bit floating point arithmetic. The PowerPC G4 family supports two bus technologies, the older 60x bus which it shares with the PowerPC 600 and PowerPC 7xx families, and the notably more advanced MPX bus. Devices that utilize the 60x bus can be made compatible with ...
Cell (processor) Cell is a 64-bit multi-core microprocessor microarchitecture that combines a general-purpose PowerPC core of modest performance with streamlined coprocessing elements [2] which greatly accelerate multimedia and vector processing applications, as well as many other forms of dedicated computation.

In 2003, 64-bit CPUs were introduced to the mainstream PC market in the form of x86-64 processors and the PowerPC G5. A 64-bit register can hold any of 2 64 (over 18 quintillion or 1.8×10 19) different values. The range of integer values that can be stored in 64 bits depends on the integer representation used.

Windows 11 only supports 64-bit systems such as those using an x86-64 or ARM64 processor; IA-32 and ARM32 processors are no longer supported. [129] Thus, Windows 11 is the first consumer version of Windows not to support 32-bit processors (although Windows Server 2008 R2 is the first version of Windows Server to not support them).
