| Parameter | 8085 microprocessor | 8086 microprocessor |
| Definition | The 8085 is an accumulator-based 8-bit microprocessor that can process 8-bit of data at a time. | The 8086 is a register-based 16-bit microprocessor that can process 16-bit of data at a time. |
| Type | It is accumulator-based. | It is register-based. |
| Memory segmentation | The 8085 microprocessor does not support memory segmentation. | The 8086 microprocessor supports memory segmentation, i.e. the memory of the 8086 microprocessor is segmented which means the 20-bit address bus can access 1 MB of memory but it uses only four 64 kB segments from it. |
| Arithmetic logic unit (ALU) size | 8085 contains an 8-bit ALU size. | 8086 contains a 16-bit ALU size. |
| Processor configuration | It is a single-processor configuration microprocessor. | It is a multiprocessor configuration microprocessor. |
| Modes of operation | The 8085 microprocessor supports only a single mode of operation. | The 8086 microprocessor supports two modes of operation viz. minimum mode and maximum mode. |
| Pipelining architecture | This microprocessor doesn’t support pipelining architecture. | The 8086 microprocessor supports pipelining architecture. |
| Processor configuration | 8085 is a single-processor configuration microprocessor. | 8086 is a multiprocessor configuration microprocessor. |
| Cost | 8085 is cheaper in comparison with the 8086 microprocessor. | 8086 is expensive in comparison with the 8085 microprocessor. |
