Difference between 8085 and 8086

Difference between 8085 and 8086

A key difference between the 8085 and 8086 microprocessors is that the 8085 has an 8-bit data bus, while the 8086 has a 16-bit data bus. This means that the 8086 can transfer twice as much information per clock cycle. Additionally, the 8086 has a number of other architectural improvements that make it faster and more efficient than the 8085. For example, it includes a pipelining technique that allows several instructions to be executed in parallel, which increases processing speed. As a result, the 8086 is better suited for more demanding tasks such as gaming or multimedia applications.

What is 8085?

8085 is an 8-bit microprocessor introduced by Intel in 1976. It is a successor to the 8086 and was used in a wide variety of personal computers and other electronic devices. The 8085 was popular for its low cost and ease of use, and it quickly became one of the most popular 8-bit microprocessors. However, it was limited by its relatively small address space and lack of certain features, such as floating-point arithmetic. Nevertheless, the 8085 remained in use until the early 1990s, when it was gradually replaced by newer and more powerful microprocessors.

What is 8086?

8086 is a type of microprocessor chip that was introduced by Intel in 1978. It was the first 16-bit microprocessor, and it quickly became popular for use in personal computers. The 8086 chip had a number of features that made it attractive to computer manufacturers, including a high speed and a wide instruction set. 8086 chips were used in a number of early PCs, including the IBM PC and the Apple II. Today, 8086 chips are no longer produced, but they remain an important part of computer history.

Difference between 8085 and 8086

  • 8085 and 8086 are two microprocessor chips designed by Intel. The 8085 was released in 1977, while the 8086 was released in 1978. Both chips are based on the same basic architecture, but there are some important differences between them. The 8085 has a 16-bit address bus, which allows it to access 64 KB of memory. The 8086, on the other hand, has a 20-bit address bus, which allows it to access 1 MB of memory.
  • In addition, the 8086 has a larger instruction set than the 8085, which makes it more powerful. Finally, the 8086 is faster than the 8085, with a clock speed of 8 MHz compared to 4 MHz for the 8085.
  • As a result, the 8086 is better suited for applications that require more speed and memory. However, the 8085 is still widely used in many older devices due to its low cost and simple design.


The bottom line is that 5W30 oil is lighter and thinner than 5W40, meaning it flows more easily at lower temperatures. This makes it a better choice for colder climates or vehicles that don’t see a lot of use during the winter months. If you live in a warm climate or your vehicle sees a great deal of action year-round, then 5W40 would be the better option.
