ARM architecture targeting smartphones and tablet computers first sold on September 2013ĭifference between 32-bit vs.The first AMD64-based processor, the Opteron, was released in April 2003.It is used in RISC ( reduced instruction set computing) based workstations and server in the early 1990s.64-bit CPUs have been used in supercomputers since the 1970s.Here, are important landmarks from the history of 64-bit processors: In 2000 AMD processor and Intel Pentium processors also start using 32-bit processors.The 32-bit processor was the main processor which was widely used all over the world in the early 1990s.Here, are important landmarks from the history of 32-bit processors: 32-bit operating systems and applications require 32-bit CPUs while 64-bit OS demands 64-bit CPU.32-bit processors is not an ideal option for stress testing and multi-tasking whereas 64-bit processors are best for performing multi-tasking and stress testing.32-bit processors need a 32-bit operating system whereas 64-bit processors can run either on 32 or 64 64-bit operating systems.

32-bit systems limited to 3.2 GB of RAM while 64-bit systems will enable you to store up to 17 Billion GB of RAM.32-bit processors have 4 GB addressable space while 64-bit processors have 16 GB addressable space.
