The Pentium III 866MHz is manufactured using Intel's .18 micron six metal layer process. It uses a fluorine-doped SiO2 (SiOF) dielectric for reduced capacitance. Its 106mm square die packs 28-million transistors into a die 4mm square larger than the Athlon's. Spacing changes were made to extend the life of aluminum as an interconnect material and push off the transition to copper. According to Intel, copper interconnects is not yet a mature technology, may reduce yields and has not proven itself to be advantageous over aluminium at current processor speeds. Notched poly profiles are used to cut .13 micron gates to .10 micron size, thereby increasing switching speed and Intel's SSE and MMX instruction sets are fully supported.
Those are the details for what is essentially the original Coppermine CPU running at 866MHz. But we know what you really want is the benchmarks...
