8085 8 bit mc and 8086 16 bit mc and 8085 don't have instruction Que and 8086 have instruction queue

8086 has 20 address lines and 16 data lines and supports HARVARD architecture as compared to 8085 which has 16 address lines and 8 data lines, so 8086 has higher index and thus accessing large memory, also the operating speed of 8086 is greater due to presence of instruction queue.

As we know 8086up supports pipeline so it is faster than 8085up which is don't support pipeline. Due to 20 address line, 8086 has more memory space than 8085up which has 16 address line (1MB former, 64KB later)
