What is the bus speed of PCI-X 2.0?

133MHz
266MHz
400MHz
533MHz

The correct answer is: 533MHz

The bus speed of PCI-X 2.0 is 533 MHz. This version of the PCI-X standard significantly improves throughput compared to its predecessors. Specifically, PCI-X 2.0 is part of a series of specifications designed to enhance performance and support for high-bandwidth devices by offering higher clock speeds and greater data transfer rates. In practical terms, this higher bus speed allows PCI-X 2.0 to handle data more efficiently, effectively making it suitable for use in servers and workstations where increased performance is critical. Each version of PCI-X has defined bus speeds, with PCI-X 2.0 leading the series, which is vital for modern computing environments requiring robust data handling capabilities.
