The Processor Direct Slot (PDS) is an expansion slot introduced by Intel in 1997 as part of the Slot 1 architecture. It was designed to provide a direct connection between the processor and the motherboard, allowing for faster and more efficient data transfer.

Overview[edit | edit source]

The Processor Direct Slot was developed as a successor to the earlier Socket 7 architecture, which had limitations in terms of data transfer speed and performance. The PDS aimed to address these limitations by providing a dedicated slot for the processor, allowing for a direct connection to the motherboard.

The PDS utilized a 242-pin slot, which was larger than the previous Socket 7 design. This allowed for more pins and improved electrical connections, resulting in better performance and stability. The slot was designed to accommodate the Pentium II and Pentium III processors, which were popular during that time.

Features[edit | edit source]

One of the key features of the Processor Direct Slot was its compatibility with the Accelerated Graphics Port (AGP) interface. This allowed for the integration of high-performance graphics cards directly into the motherboard, enhancing the overall system performance.

The PDS also supported a voltage of 2.8V, which was higher than the previous Socket 7 standard. This higher voltage allowed for increased power delivery to the processor, enabling it to operate at higher clock speeds and handle more demanding tasks.

Advantages[edit | edit source]

The Processor Direct Slot offered several advantages over its predecessor, the Socket 7 architecture. These advantages included:
