S.No.8086 Microprocessor8088 Microprocessor1The instruction Queue is 6 byte long.
The instruction Queue is 4 byte long.
2In 8086 memory divides into two banks, up to 1,048,576 bytes.
The memory in 8088 does not divide in to two banks as 8086.
3The data bus of 8086 is 16-bit wide
The data bus of 8088 is 8-bit wide.
4It has BHE( bar ) signal on pin no. 34 & there is no SSO(bar) signal.
It does not has BHE( bar ) signal on pin no. 34 & has only SSO(bar) signal. It has no S7 pin.
5The output signal is used to select memory or I/O at M/IO(bar) but if IO(bar)/M low or logic '0' it selects I/O devices and if IO(bar)/M is high or logic '1'it selects memory.The output signal is used to select memory or I/O at M(bar)/IO but if IO/M(bar) is low or at logic '0',it selects Memory devices and if IO/M(bar) is high or at logic '1'it selects I/O.6It needs one machine cycle to R/W signal if it is at even location otherwise it needs two.
It needs one machine cycle to R/W signal if it is at even location otherwise it needs two.
In 8086, all address & data Buses are multiplexed.
In 8088, address bus, AD7- AD0 buses are multiplexed.
It needs two IC 74343 for de-multiplexing AD0-AD19.
It needs one IC 74343 for de-multiplexing AD0-AD7.
The 8086/8088 family of microprocessors was introduced by Intel.
Ten microprocessors are the 4004, 4040, 8008, 8080, 8085, 8086, 8088, 80286, 80386, and 80486.There are many more, and this list only included some of the Intel microprocessors, in mostly historical order.
The 8086/8088 is the general purpose processor. The 8087 is the math co-processor for the 8086/8088.
1978 - 8086 1979 - 8088 First IBM PC used 8088. I think later low end IBM PC's used 8086.
The 8088 is slower than the 8086 because the 8088 is running an 8-bit bus, while the 8086 runs a 16-bit bus. The two processors are the same, 16-bit processors, but the 8088 requires twice as many memory accesses to do the same amount of work as the 8086.
It starts with the 4004 chipset (4 bit) and 8008 microprocessor (8 bit). The successor of the 4004 was the 4040, but this architecture was a dead end. The successors of the 8008 were the 8080, 8085, 8086, 8088, 80186, 80286, 80386, 80486, Pentium, etc. including the current multicore microprocessors. IBM chose to base their PC on the 8086 and 8088, then as successive newer microprocessors were developed new versions of the IBM PC used those microprocessors. Intel also produced many specialized microprocessors and microcontrollers including some RISC microprocessors (e.g. i860, i960). Current Apple Macintosh computers also use the latest Intel multicore microprocessors.
See the related link, below, for the 8086/8088 pinout.
The difference between the 8086 and the 8088 is that the 8086 has a 16 bit data bus and that the 8088 has an 8 bit data bus. Both processors are the same 16 bit processor, and both have a 20 bit address bus. The 8086 is twice as fast as the 8088 in terms of data transfer rate on the bus for the same bus clock speed.

The 8085 and 8086/8088 operate on 5 volts.
The 8086/8088 is a CISC based architecture.
No. RST7.5 is a maskable interrupt on the 8085, not the 8086/8088.
