理解i586/x86 vs x64

• Overview

  Normally, you see two types of downloads avaiable for Windows platforms:

  • x86 for 32bit
  • x64 (or AMD64 or x86-64) for 64bit

  The x in x86 means any member of the x86 family, such as 286(16-bit), 386(32-bit), 486 …, all of which were based on the Intel 8086 architecture, This list includes the 586.

• 586

  It was very common many years ago to hear about computers with 386 or 486 processors, but you rarely heard of 586, because the Intel 586 was actually named the Pentium (Pent for 5).
