DIGITAL EXTENDS ALPHA PERFORMANCE LEAD
WITH SPEED UPGRADES TO ALPHA MICROPROCESSORS

...Alpha 21164 Up to 333MHz...

MAYNARD, Mass., October 2, 1995 -- The world's fastest micro-
processors just got faster with the announcement today of speed
upgrades to the Alpha 21164 (the BIPS chip) and Alpha 21064A
microprocessors. Digital Equipment Corporation will now offer the
Alpha 21164-333MHz chip, with estimated SPECint92 performance of 400
and SPECfp92 of 570, and the Alpha 21064A-300MHz chip, with
estimated SPECint92 of 220 and SPECfp92 of 300. These high-
performance chips, targeted initially at the high performance
workstation and server markets, significantly outpace the
competition.

"Alpha microprocessors have consistently hit and often exceeded
performance targets and delivery times since their introduction more
than three years ago," stated Ed Caldwell, vice president, Digital
Semiconductor, a Digital Equipment Corporation business. "The Alpha
architecture is designed to deliver high performance in every
generation and design upgrade. Today's announcement by Digital is an
example of how we are able to push each successive Alpha generation
to ever greater performance levels."

Setting Industry Records

Today's announcement shows the significant performance
advantage of Alpha microprocessors. The Alpha 21164-333MHz
processor significantly outperforms all other currently shipping or
sampling chips. It performs integer intensive applications 1.7 to
2.9 times faster and floating point intensive applications 1.6 to
3.2 times faster than any available competitive processors. This
difference is due in part to Digital Semiconductor's advanced,
world-class manufacturing process and semiconductor design
capabilities, which allow Digital to deliver a processor at a
record-setting 333 MHz. Both the Alpha 21164-333MHz and the Alpha
21064A-300MHz microprocessors are sampling now and are
pin-compatible with previously announced versions. They enable easy
enhancement to existing systems.
