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:
“The parents who wish to lead a quiet life I would say: Tell your children that they are very naughtymuch naughtier than most children; point to the young people of some acquaintances as models of perfection, and impress your own children with a deep sense of their own inferiority. You carry so many more guns than they do that they cannot fight you. This is called moral influence and it will enable you to bounce them as much as you please.”
—Samuel Butler (18351902)
“... your problem is your role models were models.”
—Jane Wagner (b. 1935)
“Today it is not the classroom nor the classics which are the repositories of models of eloquence, but the ad agencies.”
—Marshall McLuhan (19111980)
