            PROXY STATEMENT FOR 1998 ANNUAL MEETING OF SHAREHOLDERS
 
                               ----------------
 
                INFORMATION CONCERNING SOLICITATION AND VOTING
 
GENERAL
 
  The enclosed proxy is solicited on behalf of OPTi Inc. ("OPTi" or the
"Company") for use at the Annual Meeting of Shareholders (the "Annual
Meeting") to be held on August 25, 1998 at 3:30 p.m., local time, or at any
postponement or adjournment thereof, for the purposes set forth herein and in
the accompanying Notice of Annual Meeting of Shareholders. The Annual Meeting
will be held at the Embassy Suites Hotel, 901 East Calaveras Blvd., Milpitas,
California 95035. The telephone number at that location is (408) 942-0400.
 
  These proxy solicitation materials were mailed on or about July 31, 1998 to
all shareholders entitled to vote at the meeting.
 
PURPOSES OF THE ANNUAL MEETING
 
  The purposes of the Annual Meeting are to (i) elect four directors to serve
for the ensuing year and until their successors are duly elected and
qualified, (ii) ratify the appointment of Ernst & Young LLP as the Company's
independent auditors for the fiscal year 1998, and (iii) transact such other
business as may properly come before the Annual Meeting and at any and all
postponements or adjournments thereof.
 
RECORD DATE AND SHARE OWNERSHIP
 
  Only shareholders of record at the close of business on July 7, 1998 (the
"Record Date") are entitled to receive notice of and to vote at the Annual
Meeting. At the Record Date, 13,298,191 shares of the Company's Common Stock
were issued and outstanding. For information regarding security ownership by
management and by 5% shareholders, see "OTHER INFORMATION--Share Ownership of
Directors, Officers and Certain Beneficial Owners." The closing price of the
Company's Common Stock on the Nasdaq National Market on the Record Date was
$6.9375 per share.
 
REVOCABILITY OF PROXIES
 
  Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before its use by delivering to the Secretary of the
Company at its principal executive offices, 1440 McCarthy Boulevard, Milpitas,
California, 95035, a written notice of revocation or a duly executed proxy
bearing a later date or by attending the Annual Meeting and voting in person.
Attending the Annual Meeting in and of itself will not constitute a revocation
of a proxy.
 
VOTING AND SOLICITATION
 
  Every shareholder voting in the election of directors may cumulate such
shareholder's votes and give one candidate a number of votes equal to the
number of directors to be elected multiplied by the number of shares held by
such shareholder, or distribute the shareholder's votes on the same principle
among as many candidates as the shareholder deems fit, provided that votes
cannot be cast for more than four (4) candidates. However, no shareholder
shall be entitled to cumulate votes unless the candidate's name has been
placed in nomination prior to the voting and the shareholder, or any other
shareholder, has given notice at the Annual Meeting prior to the voting of the
intention to cumulate the shareholder's votes. On all other matters, each
share has one (1) vote.

 
  Shares of Common Stock represented by properly executed proxies will, unless
such proxies have been previously revoked, be voted in accordance with the
instructions indicated thereon. In the absence of specific instructions to the
contrary, properly executed proxies will be voted: (i) FOR the election of
each of the Company's nominees as a director; and (ii) FOR ratification of the
appointment of Ernst & Young LLP as independent auditors for fiscal 1998. No
business other than that set forth in the accompanying Notice of Annual
Meeting of Shareholders is expected to come before the Annual Meeting. Should
any other matter requiring a vote of shareholders properly arise, the persons
named in the enclosed form of proxy will vote the shares they represent as the
Board of Directors may recommend.
 
  The cost of this solicitation will be borne by the Company. The Company may
reimburse brokerage firms and other persons representing beneficial owners of
shares for their expenses in forwarding solicitation material to such
beneficial owners. Proxies may also be solicited by certain of the Company's
directors, officers and regular employees, without additional compensation,
personally or by telephone, telegram or letter.
 
QUORUM; ABSTENTIONS; BROKER NON-VOTES
 
  The required quorum for the transaction of business at the Annual Meeting is
a majority of the shares of Common Stock issued and outstanding on the Record
Date. Shares that are voted "FOR" or "AGAINST" a matter are treated as being
present at the meeting for purposes of establishing a quorum and are also
treated as shares "represented and voting" at the Annual Meeting (the "Votes
Cast") with respect to such matter.
 
  While there is no definitive statutory or case law authority in California
as to the proper treatment of abstentions or broker non-votes, the Company
believes that both abstentions and broker non-votes should be counted for
purposes of determining the presence or absence of a quorum for the
transaction of business. The Company further believes that neither abstentions
nor broker non-votes should be counted as shares "represented and voting" with
respect to a particular matter for purposes of determining the total number of
Votes Cast with respect to such matter. In the absence of controlling
precedent to the contrary, the Company intends to treat abstentions and broker
non-votes in this manner. Accordingly, abstentions and broker non-votes will
not affect the determination as to whether the requisite majority of Votes
Cast has been obtained with respect to a particular matter.
 
DEADLINE FOR RECEIPT OF SHAREHOLDER PROPOSALS
 
  Proposals of shareholders of the Company which are intended to be presented
by such shareholders at the 1999 Annual Meeting of Shareholders must be
received by the Company no later than December 31, 1998 in order to have them
included in the proxy statement and form of proxy relating to that meeting.
 
FISCAL YEAR END
 
  The Company's fiscal year ends on December 31. Fiscal 1997 ended on December
31, 1997 and is referred to herein as the "Last Fiscal Year."

                             ELECTION OF DIRECTORS
 
DIRECTORS AND NOMINEES FOR DIRECTORS
 
  A board of four directors is to be elected at the Annual Meeting. Unless
otherwise instructed, the proxy holders will vote the proxies received by them
for the Company's four (4) nominees named below, all of whom are presently
directors of the Company. In the event that any nominee of the Company is
unable or declines to serve as a director at the time of the Annual Meeting,
the proxies will be voted for any nominee who shall be designated by the
present Board of Directors to fill the vacancy. In the event that additional
persons are nominated for election as directors, the proxy holders intend to
vote all proxies received by them in such a manner in accordance with
cumulative voting as will assure the election of as many of the nominees
listed below as possible, and, in such event, the specific nominees to be
voted for will be determined by the proxy holders. The Company is not aware of
any nominee who will be unable or will decline to serve as a director. The
term of office of each person elected as a director will continue until the
next Annual Meeting of Shareholders or until a successor has been duly elected
and qualified.
 
                 THE COMPANY'S BOARD OF DIRECTORS RECOMMENDS A

(1) All options to Named Officers are granted under the Company's 1993 Stock
    Option Plan at an exercise price equal to the fair market value on the
    date of grant. These stock options vest and become exercisable as to 1/8
    of the shares beginning six (6) months following the vesting commencement
    date and as to 1/48 of the shares on the first day of each month
    thereafter. Under the terms of the Option Plan, the option plan
    administrator retains the discretion, subject to certain limitations
    within the plan, to modify, extend, renew or accelerate the vesting of
    options and to reprice outstanding options. In particular, subject to
    Board approval, the stock plan administrator may reduce the exercise price
    of an option to the current fair market price of the underlying stock if
    the price of such stock has declined since the date on which the option
    was granted.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  In February 1993, the Company established a compensation committee of the
Board of Directors which currently consists of Messrs. Braham and Mr. Lin.
Wilson Sonsini Goodrich & Rosati, Professional Corporation, of which Mr.
Braham is a partner, was retained as legal counsel by the Company during the
Last Fiscal Year.
 
CERTAIN TRANSACTIONS
 
  See "EXECUTIVE COMPENSATION--Compensation Committee Interlocks and Insider
Participation" above.
 
  The Company's policy is that it will not make loans to, or enter into other
transactions with, directors, officers or affiliates unless such loans or
transactions are (i) approved by a majority of the Company's independent
disinterested directors, (ii) may reasonably be expected to benefit the
Company, and (iii) will be on terms no less favorable to the Company than
could be obtained in arm's length transactions with unaffiliated third
parties.
 
  The Company has entered into indemnification agreements with each of its
directors and executive officers. Such agreements require the Company to
indemnify such individuals to the fullest extent permitted by California law.

                       REPORT OF COMPENSATION COMMITTEE
              OF THE BOARD OF DIRECTORS ON EXECUTIVE COMPENSATION
 
  The Compensation Committee of the Board of Directors establishes the general
compensation policies of the Company as well as the compensation plans and
specific compensation levels for executive officers. It also administers the
Company's employee stock benefit plans and the 1993 Bonus Plan (the "Bonus
Plan"). The Compensation Committee is currently composed of independent, non-
employee directors who have no interlocking relationships as defined by the
Securities and Exchange Commission.
 
  The Compensation Committee believes that the compensation of the executive
officers, including that of the Chief Executive Officer (collectively, the
"Executive Officers") should be influenced to a very significant extent by the
Company's financial performance. The Committee establishes the salaries of all
of the Executive Officers by considering various factors, including the
following: (i) the Company's financial performance for the past year, (ii) the
opportunity of the Executive to participate in the Company's success through
equity ownership and stock options, (iii) the salaries of executive officers
in similar positions of comparably-sized companies, and (iv) the critical
importance of cost control in the Company's business in light of ongoing
competition. In addition to salary, the cash portion of the Company's
executive compensation packages includes discretionary bonuses which are paid
quarterly based on the Company's operating results. The Committee believes
that the Company's executive Officer salaries and cash compensation are
currently less than or comparable to the compensation paid to executives at
similarly-sized businesses in the industry.
 
  The Company's Bonus Plan provides that the maximum aggregate bonuses to be
paid to any individual Executive Officer in the year will in no event exceed
two (2) times the base salary of such Executive Officer. In addition, the
aggregate quarterly bonuses which may be paid to all Executive Officers will
not exceed 5% of the Company's pre-tax, pre-bonus income for the quarter.
 
  Acting with the advice of the Committee, the Board of Directors periodically
grants options to Executive Officers. The Committee views stock option grants
as an important component of its long-term, performance-based compensation
philosophy. Since the value of an option bears a direct relationship to the
Company's stock price, the Committee believes that options motivate Executive
Officers to manage the Company in a manner which will also benefit
shareholders. Options are granted at the current market price on the date of
grant.
 
  The compensation package for the Company's Chief Executive Officer, Bernard
T. Marren, includes three elements: (i) base salary, (ii) performance bonus
and (iii) stock options. The base salary was determined through a comparison
of base salaries paid with respect to chief executive officers of other
publicly-traded semiconductor companies located in Northern California. The
performance bonus element has been established to provide variable bonus
compensation to the CEO based on the Company's actual operating results during
fiscal 1996 and thereafter, including both sales and net income measurements.
The stock option award is intended to provide long-term compensation to the
CEO based on the stock performance of the Company. The options vest over a
four (4) year period. In general, the Committee believes that the compensation
package of the CEO is closely tied to the financial performance of the Company
and has a high degree of variability based on such performance.

  The following graph shows a comparison of cumulative total shareholder
return, calculated on a dividend reinvested basis, from the effective date of
the initial public offering of the Company's Common Stock (May 13, 1993)
through the Last Fiscal Year end (December 31, 1997) for OPTi Inc., the CRSP
Index for Nasdaq Stock Market (U.S. Companies) (the "Nasdaq Index') and the
CRSP Index for Nasdaq Electronic Components Stocks (the "Nasdaq Electronic
Components Index"). The graph assumes that $100 was invested in the Company's
Common Stock on May 13, 1993 at the initial public offering price and in the
Nasdaq Index and the Nasdaq Electronic Components Index on May 13, 1993. Note
that historic stock price performance is not necessarily indicative of future
stock price performance.
