On which dimension?
Digital builds many computers which are the fastest at various benchmarks.
Perhaps some of our systems (a system is more than a computer) will support your
application better than a competitor's. What is your application? What are
your requirements? How much money are you willing to spend?
By various benchmarks, your mother and father provided you with a copy
of what is arguably the fastest known fully-general-purpose computing
package: the human brain.
The fastest known silicon-based processors are generally purpose-dedicated
(often highly custom) high-performance processor chips -- organizations
including various militaries around the world are common users of these
Digital holds various microprocessor records for the more "mundane"
general purpose silicon-based microprocessors -- versions of the Alpha
21164 are expected to be running at 500 MHz by the end of 1996, and this
single 500 MHz part is capable of processing two billion instructions
Currently shipping Alpha microprocessor system performance estimates:
