The 80286 performs at twice the speed of its predecessor (the Intel 8086) per clock cycle, and is able to address up to 16 megabytes of RAM, in contrast to the 1MB the 8086 can work with. On DOS machines this additional ram capability can only be utilised via extended memory emulation, however few 286-based computers ever saw more than a megabyte of ram.
Despite their market popularity, few computers with a 80286 CPU still remain in use today.
The 286's successor was the 32-bit Intel 80386.
