Intel Pentium Integrated Circuits

Pentium 100MHz

By completing up to two instructions simultaneously in the dual 486-type integer pipelines with dependency checking and a single, onboard floating-point unit, the first Pentium (66-200 MHz) processors sported separate 8-Kbyte instruction and data caches, greatly enhanced 486 performance. With the introduction of MMX (reported as MultiMedia eXtension or Matrix Math eXtension) enhancements, the original Pentium is now called the Pentium Classic.

Illustrated in the digital image above is a reflected light differential interference contrast (DIC) digital image of a small section from a Intel Pentium 100MHz wafer showing the a scribe line intersection, Intel logo, and the 80P54C chip identifier using oblique illumination with blue, red, and yellow gels.
