Intel's latest Pentium III processors are manufactured with an 0.13 μ process for higher clock speeds. The newest Pentium III-compatible processors operate at 1.13 GHz and include 512 K of L2 cache. These new processors have been designed to allow for better graphics performance, high clock speeds, and the use of multiple processors in high performance systems.
In multi-processor systems, any unused processor socket must be populated with a special terminator to ensure that each data or clock line "sees" the correct impedance. This minimizes reflections and other potential signal problems which can develop in high-speed systems.
