Models
There are three distinctive models of the Challenge. The first model, simply known as the "Challenge" used the 64-bit R4400. With the introduction of the R8000, the Challenge was upgraded to support more processors and memory as well as featuring support for this new processor. Such systems are known as the "POWER Challenge". During the final years of the Challenge architecture's useful life, the line was upgraded to support R10000 microprocessors. Older Challenge systems using the R10000 were known as the "Challenge 10000", while the newer POWER Challenge systems using the R10000 were known as the "POWER Challenge 10000".
Models suffixed with "GR" (for "Graphics Ready") could support the RealityEngine and InfiniteReality graphics subsystems. Standard models were either servers or supercomputers with no graphics support.

Famous quotes containing the word models:
“French rhetorical models are too narrow for the English tradition. Most pernicious of French imports is the notion that there is no person behind a text. Is there anything more affected, aggressive, and relentlessly concrete than a Parisan intellectual behind his/her turgid text? The Parisian is a provincial when he pretends to speak for the universe.”
—Camille Paglia (b. 1947)
“Friends broaden our horizons. They serve as new models with whom we can identify. They allow us to be ourselves—and accept us that way. They enhance our self-esteem because they think we’re okay, because we matter to them. And because they matter to us—for various reasons, at various levels of intensity—they enrich the quality of our emotional life.”
—Judith Viorst (20th century)
“Grandparents can be role models about areas that may not be significant to young children directly but that can teach them about patience and courage when we are ill, or handicapped by problems of aging. Our attitudes toward retirement, marriage, recreation, even our feelings about death and dying may make much more of an impression than we realize.”
—Eda Le Shan (20th century)
