amended, of the shares of the Company's Common Stock, par value $0.01 per
share (the "Shares"), to be issued in connection with the merger of NexGen,
Inc., a Delaware corporation ("NexGen") with a subsidiary of the Company or

the Company, AMD Merger Corporation and NexGen, dated as of October 20, 1995,
as amended December 11, 1995 (as amended, the "Merger Agreement").

As such counsel and in connection with the opinion expressed below, we have
examined copies of the Registration Statement, the Company's Certificate of
Incorporation as amended to date, the Company's By-Laws as amended to date,

Based upon the foregoing, we are of the opinion that the Shares have been
validly authorized and, when issued pursuant to the terms of the Merger
Agreement, will be validly issued, fully paid and non-assessable.

We hereby consent to the use of this opinion as an exhibit to the
Registration Statement and to the reference to our firm under the caption
