What is the difference between the Intel 8080 and the Intel 8085?

The 8086 has 16 bit data bus; the 8088 has an 8 bit data bus. The 8086 has a 6 byte instruction queue, and the 8088 has a 4 byte queue. The 8088 was the chip used in the first IBM PC; the 8086 wasn't used until later models. Since they share the exact same instruction set, which is referred to as the "x86 instruction set" these days, this is often confused. 8085 is a 8 bit processor,number of flags are 5 and memory capacity is 64KB while 8086 is a 16 bit processor ,number of flags are 9 and memory capacity is 1 MB.The main difference between 8085 and 8086 is that 8086 uses pipelining. The 8086/8088 microprocessor is a 16 bt computer, with a 20 bit address bus using a segmented memory architecture. The execution unit architecture, registers, instructions, etc. in both is the same. The bus interface unit on the 8086 is 16 bits wide, where on the 8088 it is 8 bits wide.
