Not necessarily. In the 8085, for instance, this is true. In the 8088, however, the processor is a 16 bit processor with an 8 bit data bus. The same is true for the 80386sx - it is a 32 bit processor on a 16 bit bus.
In technology, the bus is used to carry data. The width of a data bus helps determine the amount of bytes that can be carried out each second.
The width of a data bus is referred to as the data path size. An example would be a 16 bit bus can transmit 16 bits of information
Intel has released processor with a variety of bus / memory widths. The 386SX had a 16-bit data width, the 386DX and 486 had a 32-bit bus width, and the Pentium had a 64-bit data bus.
processing speed of the computer will be increased when the data bus is wider
The speed of system random-access memory is determined by two factors: bus width and bus speed. Bus width refers to how many bits of information RAM can send to the CPU at the same time.
The density of the module
The bigger the data bus, the more data can be fetched in one go and processed, making the computer faster
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.

bus width
A BUS is a port that connects a card (CPU, GPU, Internet card, etc) to the Motherboard. Bus size refers to the number of pins in the bus. different models have different BUS sizes. the more pins, the faster the transfer speed of information. the PCI Express (PCIE) is the fastest and newest BUS.
Because its a microcontroller with an 8 bit data bus width.
