Somewhat after the 8086, which was somewhat after the 8085. The 8086 was developed between mid 1976 and early 1978, while the 8088 was developed in 1979.

The 8086/8088 is the general purpose processor. The 8087 is the math co-processor for the 8086/8088.
The Intel 8088.
The co-processor on an 8086/8088 is the 8087 math co-processor. The motherboard will be designed with an extra socket for the 8087, which then integrates with the 8086/8088 to make a single unified processor.
Intel
The original 8088 processor had a maximum clock frequency of 5 MHz. As implemented in the original IBM PC, it ran at 4.77 MHz. There were variations of the 8088 that could run at 8 MHz.
because its word length is 16 bit
An Intel 8088 @ 4.77 MHz.
8088 processor? Get yourself some fresh gear. Cripe's sake.
the pin configuration of a processor means that the diagramatic representation of block diagram of processor representing various pins and the function of that pins
I don't know for sure, but I think it'd be the 8088.
Because that's what Intel chose to do. The 8086 was released in 1978. The 8088 was released in 1979, and it was the same 16 bit processor core, but running on a 8, instead of a 16, bit bus, making it more tenable in low end, cheap, systems, such as the IBM PC.
