A 7th generation x86 microprocessor fetches,decodes, and retires three x86
instructions per cycle in a 15-stage pipeline. The chip uses 0.25=B5m
six-layer metal CMOS plus tungsten local interconnect.

An x87-compatible out-of-order superscalar floating-point unit in 0.25=B5m
six-layer-metal CMOS executes traditional floating-point instructions
at two FLOPS per cycle peak rate, 3DNow! SIMD instructions at four FLOPS
per cycle peak rate, and up to three MMX SIMD instructions
per cycle.

A 450MHz 7W microprocessor with an AltiVecTM instruction set implementation
and high memory bandwidth is fabricated in 1.8V CMOS
with copper interconnect. A crossbar circuit that implements the permute
instruction and a programmable 3.3/2.5/1.8V I/O buffer are used. The
10.5M-transistor chip on a 83=B5m2 die has estimated SPECint95 and SPECfp95
performance of 20.

A 600MHz IA-32 Microprocessor with Enhanced Data Streaming for Graphics
and Video

A next-generation P6 microprocessor adds 67 instructions for data
streaming. Circuit enhancements include multi-grid C4 power distribution,
decoupling techniques, improvements in dynamic circuits, and process
voltage and temperature-compensated I/O buffer designs. The
processor in 0.25=B5m 5-layer-metal CMOS achieves 600MHz.
