WebAnswer (1 of 3): The 8086 has 16-bit-wide general purpose registers in the CPU. It’s faster and more convenient to be able to load those in a single bus cycle, as compared with doing two fetches over an 8-bit-wide data bus (as in the 8088). Narrower data buses do have some advantages. Fewer pins... WebThe 8086 happens to be designed with a 16 bit external memory bus, while the 8088 is designed with a half-size 8 bit external bus. This makes no difference to the software, but it means that 8088 systems can be built with fewer components, so they are cheaper. 8086 systems can often be twice as fast though, because they can fetch 16 bits at a time. sharing faith verses
