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.
AMD was a major supplier of various integrated circuits: logic, DRAM, the 2900 family bitslice bipolar microprocessor chipset, etc. However they lacked a single chip MOS microprocessor like those made by Intel, Motorola, Zilog, Texas Instruments, National Semiconductor, etc. When Intel encountered a problem meeting demand for their 80386 single chip MOS microprocessor they sought out another chip manufacturer with available fabrication facilities. At the time AMD had surplus fabrication facilities and Intel and AMD quickly reach an agreement where Intel would provide AMD with the masks and other manufacturing details for the 80386 and AMD would licence some of their patents to Intel. The two companies would then share the market and sales of the 80386. When Intel designed their 80486 single chip MOS microprocessor, they had already expanded their fabrication facilities enough that they would not need help from AMD to make enough 80486 microprocessors to meet demand. However AMD expected that the original 80386 agreement demanded Intel provide masks and other manufacturing details for successive Intel designed microprocessors (beginning with the 80486). Intel refused and the case went to court. Meanwhile AMD began designing an 80486 microprocessor clone on their own. Intel claimed in the court case that AMD could not do that as 80486 was a trademark, but the court pointed out that trademark law does not permit trademarking of numbers. This allowed both Intel and AMD to manufacture, market, and sell their own independently designed versions of the 80486 microprocessor. When Intel designed their 80586 single chip MOS microprocessor, because of the court decision that numbers could not be trademarked Intel chose to use a word which could be trademarked instead of 80586 and (somewhat unimaginatively) made up the word Pentium for the 80586. Of course AMD designed their own 80586 clone independently (as they had done with the 80486) and made up their own word as a trademark for it. Ever since then when Intel has enhanced the x86/Pentium architecture, AMD has independently designed a clone supporting the new architectural features. However AMD has their own implementation ideas to improve and optimize performance, so sometimes the Intel microprocessors have had better performance and other times the AMD microprocessors have had the better performance.
Federico Faggin and Ted Hoff were the chief designers of the first Intel chipset called "Intel 4004". The Intel 4004 was a 4-bit central processing unit made from 1971 to 1981.

Apple is doing great and the transition to Intel processors has been complete for several years.
The Intel 80386 is a 32-bit processor.
The 4004 was Intel's first microprocessor and the world's first single chip microprocessor. For the first PC as we know it (the 1981 IBM PC), it was the 8088, following with 80286, 80386, 80486 and then the Pentium line.
NONE! The 80186 was an advanced version of the 8086 but did not include support for virtual memory. It had a 64K physical address space. The 80286 was the first Intel CPU to support virtual memory but it's capabilities were limited.
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 numbers 8086 most often refer to the first generation of 16 bit computer processor chips. These where made by Intel. Later generations where named 80186, 80286, 80386, and 80486 often dropping the 80 prefix.
Intel has actually manufactured several incompatible architectures. The 4004, 8008, and 8080 are all incompatible. The 8086, 8088, 80286, 80386, 80486, Pentium (II, III, 4), and Core (2) are all backwards-compatible processors classified as "x86." Intel also created the i860 and IA-64 (Itanium) architectures.

I assume your speaking of the Intel 80286 and the 80386 computer processors. This series of processors are the reason we call "32-bit processor architecture" x86. Anyway, the importance of moving from 80286 to 80386 lies in the fact that the former could only execute 16-bit code, and the the latter supported 32-bit code. In layman terms, the 80286 could only natively calculate numbers up to 65,536-1 (65.536) without implementing advanced software to allow caclulations of numbers greater than that. The 80386, however, was capable of mathematically manipulating numbers up to 4,294,967,296-1 (or 4,294,967,295). This innovation allowed many programmers to write programs more easily without the need for them to implement extra functions to allow them to process large numbers. For this same reason, we now use 64-bit processors, and will eventually move on to 128-bit and 256-bit in the future, however, when this will happen is a matter of when hardware designers create and software programmers decide to support such a system.
