Q:

8088 CPU advantages over 8086 CPU

The 8088 came out after the 8086. What advantages did it have over the 8086, if any?

A:

It was cheaper and allowed for overall cheaper system. Wikipedia has an exhausive article about the 8088:

The 8088 was targeted at economical systems by allowing the use of an 8-bit data path and 8-bit support and peripheral chips; complex circuit boards were still fairly cumbersome and expensive when it was released. The prefetch queue of the 8088 was shortened to four bytes, from the 8086's six bytes, and the prefetch algorithm was slightly modified to adapt to the narrower bus.

In comparison, the 8086 has a 16-Bit data bus, which means that the accompanying system chips needed to be 16 Bits, which made them more complex and expensive.
