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.
The Intel 8088.
1978 - 8086 1979 - 8088 First IBM PC used 8088. I think later low end IBM PC's used 8086.
Because IBM wanted to build a computer with an 8-bit data bus. The 8086 and 8088 are the same processor, with the 8086 running on a 16-bit data bus, and the 8088 running on an 8-bit data bus. This allowed IBM to make the most use of older designs that supported 8-bit data buses, such as the 8080, the 8085, and the Z80.

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.
The Intel 8088 microprocessor was a variant of the Intel 8086 and was introduced on July 1, 1979. It had an 8-bit external data bus instead of the 16-bit bus of the 8086. The 16-bit registers and the one megabyte address range were unchanged, however. The original IBM PC was based on the 8088.
speed ofcource.. 800 mhz PC will be slower than 1099 mhz PC because of slow data rate..
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.
600 MHz or 800 MHz
The Intel 8088 is generally considered to be a 16-bit processor (most registers were 16 bit registers), and therefore had a 16-bit word length, although its external data bus was only 8 bits wide.
The original IBM PC, also known as the 5150, was was introduced on August 12, 1981.
