Intel's 800MHz FSB & AMD's 400MHz FSB

[Saint]

What is FSB? How is it critical to the whole system's performance? Is it to do with RAM ?

Front-side bus: it's the speed at which your CPU can access the computer's RAM. It's fairly important for your overall system performance. But:

1) A really fast FSB is useless if your memory can't run that fast. Really fast RAM can get really expensive, so make sure you check that out.

2) RAM speed, just like CPU speed, can't be described by just a single number. 800mhz RAM could be way more or way less than twice as fast as 400mhz RAM, depending on various things.

FSB stands for Front Side Bus and it refers to the communication pathway between the CPU (Central Processing Unit) and the rest of the system, including RAM (Random Access Memory), I/O (Input/Output) devices, and other components. It is critical to the whole system's performance as it determines the speed at which data can be transferred between the CPU and other components.

In the case of Intel's 800MHz FSB and AMD's 400MHz FSB, the higher the FSB speed, the faster the data can be transferred, resulting in better overall system performance. This is because the CPU can access data from other components more quickly, reducing the time it takes for tasks to be completed.

FSB is not directly related to RAM, but it does affect its performance indirectly. A higher FSB speed means that the CPU can access data from RAM more quickly, resulting in faster data transfer and improved overall system performance. However, the speed of RAM itself is determined by its own frequency, which is measured in MHz or GHz.

In conclusion, FSB plays a crucial role in the overall performance of a computer system by determining the speed at which data can be transferred between the CPU and other components. It is not directly related to RAM, but it does have an impact on its performance.
