The FSBs were frequently used in the 1990’s and 2000’s but now have become redundant because of another type of buses introduced in the market. Most Intel computing systems came with the front sided bus that performed the tasks of managing data between the memory controller and the processor, but only a few had the back sided buses that connected the processor with the cache. These devices have become extinct because of the emergence of HyperTransport, Intel QuickPath Interconnect and Direct Media Interface that have taken over the new devices.

They have become a common standard whenever someone wants to purchase a new computer or motherboard and have speeds ranging between 66 MHz, 133 MHz, 100 MHz, 266 MHz, and 400 MHz or more. The option of manually setting the speed is also possible through the BIOS or the motherboard jumpers but need proper settings and management.
