8 bits
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 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 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.
The Intel 8088.
The 8086/8088 family of microprocessors was introduced by Intel.
Yes, the 8086 and 8088 microprocessors are TTL (Transistor-Transistor Logic) compatible. Both processors were designed to work with standard TTL logic levels, allowing them to interface with other TTL-compatible components in a system. However, the main difference between the two lies in their data bus width; the 8086 has a 16-bit data bus, while the 8088 has an 8-bit data bus, which affects their performance and system design.
1978 - 8086 1979 - 8088 First IBM PC used 8088. I think later low end IBM PC's used 8086.
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 8088 was the microprocessor used in the original IBM PC, released in 1981. It operated at clock speeds of 4.77 MHz, which was relatively slow by modern standards. The 8088 featured a 16-bit data bus and an 8-bit external data bus, allowing it to handle a variety of tasks suitable for early personal computing. Its architecture laid the groundwork for future generations of x86 processors.
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.
