Celeron D processor's Front Side Bus:
The Celeron D processor's Front Side Bus (FSB) uses a split-transaction, deferred reply protocol like the Intel Pentium 4 processor. The FSB uses Source-Synchronous Transfer (SST) of address and data to improve performance by transferring data four times per bus clock (4X data transfer rate, as in AGP 4X). Along with the 4X data bus, the address bus can deliver addresses two times per bus clock and is referred to as a "double-clocked" or 2X address bus. Working together, the 4X data bus and 2X address bus provide a data bus bandwidth of up to 4.2 GB/s.

Address bus powerdown:
The processor includes an address bus powerdown capability that removes power from the address and data pins when the FSB is not in use. This feature is always enabled on the processor.

The Intel Celeron D processor family expands Intel's processor family into the value-priced PC market segment. Celeron D processors provide the value that offers the customer the capability to affordably get onto the Internet, and use educational programs, home-office software, and productivity applications. Celeron D processors include an integrated L2 cache, and built on Intel's advanced CMOS process technology. The Celeron D processor is backed by over 30 years of Intel experience in manufacturing high-quality, reliable microprocessors.
