80286: 16 MB Of Memory, But Still 16 Bits
Released in 1982, the 80286 was 3.6 times faster than the 8086 at the same frequency. It could manage up to 16 MB of memory, but the 286 was still a 16-bit processor. It was the first x86 equipped with a memory management unit (MMU), allowing it to manage virtual memory. Like the 8086, it did not have a floating-point unit (FPU), but could use a x87 co-processor chip (80287). Intel offered these processors at a maximum frequency of 12.5 MHz, whereas their competitors reached 25 MHz.
