ppc64

The PowerPC 970 was released in 2003 and was one of the first 64-bit processors developed for consumer-type computers, PowerMac G5 in this case.

ppc64 is an identifier commonly used within the Linux, GNU Compiler Collection (GCC) and LLVM free software communities to refer to the target architecture for applications optimized for 64-bit big-endian PowerPC and Power ISA processors.

ppc64le is a pure little-endian mode that has been introduced with the POWER8 as the prime target for technologies provided by the OpenPOWER Foundation, aiming at enabling porting of the x86 Linux-based software with minimal effort.
