128-bit

128-bit - Wikipedia, the free encyclopedia: "In computer architecture, 128-bit is an adjective used to describe integers, memory addresses or other data units that are at most 128 bits wide, or to describe CPU and ALU architectures based on registers, address buses, or data buses of that size. There are currently no mainstream general-purpose processors built to facilitate 128-bit instruction sets and operations, as 128-bit requires a buffer memory size and throughput width double the size of 64-bit processors, and a 128-bit capable processor would far exceed all practical needs. As of 2005, 64-bit processors are more than sufficient..."
