What is FSB ?
| Front-Side Bus |
| This important component is essential to speedy PC performance. In essence, the bus is a pathway over which data travels between various internal system components. The front-side bus (FSB) is the segment of the system bus that carries data between the CPU and the chipset that connects to the RAM and other devices; it generally has the greatest effect on overall performance. A system with high-performance processors and other components should also have a fast front-side bus. The budget Athlon XP, for example, is paired with a 266MHz or 333MHz FSB, while the faster Pentium 4 uses either a 400MHz or 533MHz FSB. In practice, the FSB will be an issue with only hard-core applications, such as digital video. |
