Difference between 8085 and 8086 Microprocessor?

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.

To save time of the execution

8085 microprocessor does not contain inbuilt memory, ADC, DAC whereas 8086 microprocessor contains those additional features and hence we don't need to include external memory and thus the circuit becomes compact
