Evolution in Fabrication
As time progressed, the process used to fabricate the Pentium Pro processor die and its separate cache memory die changed, leading to a combination of processes used in the same package:
- The 133 MHz Pentium Pro prototype processor die was fabricated in a 0.6 µm BiCMOS process.
- The 150 MHz Pentium Pro processor die was fabricated in a 0.50 µm BiCMOS process.
- The 166, 180, and 200 MHz Pentium Pro processor die was fabricated in a 0.35 µm BiCMOS process.
- The 256 KiB L2 cache die was fabricated in a 0.50 µm BiCMOS process.
- The 512 and 1024 KiB L2 cache die was fabricated in a 0.35 µm BiCMOS process.

Famous quotes containing the words evolution and/or fabrication:
“As a natural process, of the same character as the development of a tree from its seed, or of a fowl from its egg, evolution excludes creation and all other kinds of supernatural intervention.”
—Thomas Henry Huxley (1825–95)
“What preoccupies us, then, is not God as a fact of nature, but as a fabrication useful for a God-fearing society. God himself becomes not a power but an image.”
—Daniel J. Boorstin (b. 1914)
