Computer Hardware
This product differentiation strategy has also been used in hardware products:
- The Intel 486SX which was a 486DX with the FPU removed or in early versions present but disabled.
- AMD disables defective cores on their quad-core Phenom and Phenom II X4 processor dies to make cheaper triple-core Phenom and Phenom II X3 and dual-core X2 models without the expense of designing new chips. Quad-core dies with one or two faulty cores can be used as triple- or dual-core processors rather than being discarded, increasing yield. Some users have managed to "unlock" these crippled cores, when not faulty.
- Powerware has a line of UPS models that can be upgraded in the field (without replacing any components) to the top model (15 kVA). That is, all the models are equal, but the lower ones are sold with a power limit, which can be removed for a price.
- Casio fx-82es scientific calculator has the same ROM as fx-991es, but some functions are disabled.

Famous quotes containing the words computer and/or hardware:
“The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.”
—Gerald M. Edelman (b. 1928)
“A friend of mine spoke of books that are dedicated like this: “To my wife, by whose helpful criticism ...” and so on. He said the dedication should really read: “To my wife. If it had not been for her continual criticism and persistent nagging doubt as to my ability, this book would have appeared in Harper’s instead of The Hardware Age.””
—Brenda Ueland (1891–1985)
