             ATI reports record revenues of US $572.2 million in Q4
                     2004 revenues up 44.1% to $2.0 billion

MARKHAM,  ON - October 7, 2004 - ATI Technologies Inc. (TSX: ATY, NASDAQ:  ATYT)
today announced its second consecutive  record revenue quarter,  driven by sales
increases in both the personal computer and consumer product lines.

ATI reported revenues/1/ of $572.2 million for the fourth quarter of fiscal 2004
(ended August 31, 2004), a 50.3% increase over the fourth quarter a year
earlier. Gross margin declined 1.8 percentage points to 33.8% over the same
period of the previous year as a result of costs associated with the ramp of a
number of new desktop products. Net income/2/ per share was $0.24 for the
quarter compared to $0.09 last year. ATI's cash position increased $40.9 million
during the quarter to $548.9 million as of August 31, 2004.

ATI's fiscal 2004 annual results also produced significant revenue and earnings
growth over fiscal 2003. Revenues for the full 2004 fiscal year grew 44.1% to
$2.0 billion. Net income for the year increased nearly six-fold to $0.80 per
share from $0.14 per share in fiscal 2003.

"Our corporate strategy continues to produce returns," said David Orton, ATI's
Chief Executive Officer. "Our PCI Express desktop product line-up is the most
competitive product family on the market, resulting in tremendous customer
acceptance. In addition, the growth rate of our digital consumer business
continues to outpace the market, based on ATI's innovative products for use in
cell phones and digital televisions."

Outlook

We expect our leadership in graphics and multimedia technologies for both
digital consumer products and PCI Express-based PCs to continue driving growth
for ATI in fiscal 2005. As a result, ATI currently expects revenue for the first
quarter of fiscal 2005 to be in the range of $600 to $640 million. Gross margin,
as a percentage of revenues, is expected to be between 33 and 34%. Operating
expenses in the first quarter (excluding the expensing of stock options) are
expected to grow between 5 and 10% relative to the fourth quarter of fiscal
2004. In accordance with Canadian generally accepted accounting principles,
beginning with the first quarter of fiscal 2005, ATI will expense compensation
costs associated with stock options granted to employees after September 1,
2002. The charge in the first quarter of fiscal 2005 will be approximately $7.0
million.

ATI continues to be optimistic about its outlook for fiscal 2005, but
anticipates some seasonality, where the first quarter is strong, followed by a
slightly weaker revenue and profit profile for the second and third quarters.
The fourth quarter is expected to build off of the third quarter.

Financial Results Analysis

Revenues
- --------

Fourth quarter revenues of $572.2 million grew by 50.3% from $380.7 million in
the same period a year ago. The gains in the fourth quarter were largely driven
by revenue increases in all of our main business lines. Desktop discrete chip
revenues grew about 40% as a result of PCI Express business with OEMs and
expanded sales in the add-in-board (AIB) channel. Total notebook chip revenues
(integrated and discrete) increased almost 20% resulting from market growth that
was partially offset by market share declines in the notebook integrated market.
Handset chip revenues more than doubled for a number of reasons -- increased
demand from cell phone manufacturers, a growing number of design wins, a growing
cell phone market overall, and the increasing proportion of the market claimed
by camera phones. Our digital television revenues grew dramatically based on
market growth and continued penetration of our products among top digital TV
manufacturers.

Gross Margin
- ------------

Our gross margin for the fourth quarter of fiscal 2004 was 33.8% -- down 1.8
percentage points from 35.6% in the same period a year ago. The margin for our
desktop discrete products declined relative to the fourth quarter of the
previous year primarily due to early production costs associated with the
introduction and ramp of our new PCI Express products. Gross margin for the
fourth quarter of fiscal 2003 also benefited from higher margins in desktop
discrete. The overall margin decline of our PC products was slightly offset by
increases in our consumer products, which have margins that are typically higher
than our corporate average.

Our royalty income from Nintendo, and our non-recurring engineering revenues,
are reported under "Other" in our segmented reporting. Please see Note 11 to our
unaudited consolidated interim financial statements for further information on
our segmented reporting.

Operating Expenses
- ------------------

Selling and marketing expenses increased by 10.6% year-over-year to $30.5
million. The increase in expenses related primarily to increased staff for sales
and technical sales support, an increased investment in advertising designed to
improve ATI's brand awareness and to create demand in the PC market, as well as
increased marketing activities to support our brands, product launches, and
participation in industry trade shows.




                                                                         6 of 26


Administrative expenses were up 11.3% year-over-year to $11.7 million due to
increased staffing levels to support a growing business, and incentive-based
compensation.

Research and development expenses increased 25.8% year-over-year to $77.1
million. This increase was largely a result of additional headcount to support
broader programs in growing business areas, and increased prototyping costs -
primarily in the desktop, integrated and notebook business units. These efforts
have led to a number of design wins which we believe will result in continued
growth in our business. Higher costs associated with licensing fees also added
to the increase in R&D.

Other Charges
- -------------

We recorded other charges totaling $0.2 million in the fourth quarter. This
compares favorably to other charges of $10.4 million for the fourth quarter last
year. Last year's charges related largely to the settlement of patent litigation
and restructuring charges related to the closure of our European R&D operations.
Please see Note 8 to our unaudited consolidated interim financial statements for
further information.

Total Operating Expenses
- ------------------------

Our total operating expenses reflect the operating expenses detailed earlier, as
well as amortization of intangible assets. For further information on the
treatment of the amortization of intangible assets, please see Note 4 to our
unaudited consolidated interim financial statements.

Interest and Other Income
- -------------------------

Our interest and other income was $2.8 million in the fourth quarter of 2004,
compared with $0.7 million for the comparable period in fiscal 2003. Interest
and other income in 2004 was derived principally from interest on our higher
cash balances.

Net Income
- ----------

Net income almost tripled to $61.2 million in the fourth quarter of 2004 from
$22.3 million in the same quarter last year as a result of the significant
increase in sales.





                                                                         7 of 26

Liquidity and Financial Resources

Fourth quarter inventory levels were steady relative to the third quarter of
2004 at $254.9 million. Inventory is up 44.4% since the end of the last fiscal
year, August 31, 2003. The increase relative to August 31, 2003 is a direct
result of our substantially increased sales.

Accounts receivable were up 55.9% to $365.6 million from the year ended August
31, 2003. Accounts payable are up 43.7% to $274.8 million from the year ended
August 31, 2003. Both accounts receivable and accounts payable are within our
target range for current sales levels.

Deferred revenue for the fourth quarter was $29.1 million, a decrease of $0.2
million from the third quarter and down $8.5 million from the end of fiscal
2003. Deferred revenue primarily relates to payments associated with development
contracts where revenue is recognized on a percentage of completion basis, but
payments are made according to contract terms.

As of August 31, 2004 we had working capital of $694.7 million compared to
$430.3 million at August 31, 2003. Cash flows from operations were $35.9 million
in the fourth quarter. Our cash position was $548.9 million at the end of the
fourth quarter, up from $350.7 million at the end of fiscal 2003. Our cash
position increased mainly as a result of increased earnings throughout the
fiscal year.

1. SIGNIFICANT ACCOUNTING POLICIES

The accompanying unaudited financial statements are prepared in accordance with
Canadian generally accepted accounting principles for interim financial
statements. Certain information and note disclosures normally included in the
annual financial statements prepared in accordance with generally accepted
accounting principles have been condensed to include only the notes related to
elements which have significantly changed in the interim period. As a result,
these interim consolidated financial statements do not contain all disclosures
required to be included in the annual financial statements and should be read in
conjunction with the most recent audited annual consolidated financial
statements and notes thereto for the year ended August 31, 2003.

These consolidated condensed financial statements are prepared following
accounting policies consistent with the Company's audited annual consolidated
financial statements and notes thereto for the year ended August 31, 2003,
except for the following accounting policy adopted during the fiscal quarter
ended May 31, 2004:

(a)  The Company adopted CICA Accounting Guideline No. 13, "Hedging
     Relationships", for its derivative instruments. Commencing in the third
     quarter of fiscal 2004, the Company engaged in activities to purchase
     certain derivative financial instruments, principally forward foreign
     exchange contracts ("Forwards"), to manage its foreign currency exposures.
     The Company's policy is not to utilize derivative financial instruments for
     trading or speculative purposes.

     The Company formally documents all relationships between hedging
     instruments and hedged items, as well as its risk management objective and
     strategy for undertaking various hedge transactions. This process includes
     linking all derivatives to specific assets and liabilities on the balance
     sheet or to specific firm commitments or anticipated transactions. The
     Company also formally assesses, both at the hedge's inception and on an
     ongoing basis, whether the derivatives that are used in hedging
     transactions are highly effective in offsetting changes in fair values or
     cash flows of hedged items.

     The Company purchases Forwards to hedge anticipated Canadian dollar
     expenses pertaining to its operations in Canada. These instruments are not
     recognized in the consolidated financial statements at inception. Foreign
     exchange gains and losses on these contracts are deferred off-balance sheet
     and recognized as an adjustment to the operating expenses when the
     operating expenses are incurred.

     Realized and unrealized gains or losses associated with derivative
     instruments, which have been terminated or cease to be effective prior to
     maturity, are deferred under other current, or non-current, assets or
     liabilities on the balance sheet and recognized in income in the period in
     which the underlying hedged transaction is recognized. In the event a
     designated hedged item is sold, extinguished or matures prior to the
     termination of the related derivative instrument, any realized or
     unrealized gain or loss on such derivative instrument is recognized in
     income.

The financial information included herein reflects all adjustments (consisting
only of normal recurring adjustments), which, in the opinion of management, are
necessary for a fair presentation of the results for the interim periods
presented.





                                                                        14 of 26

2. FINANCIAL INSTRUMENTS

The Company enters into Forwards to hedge its foreign currency exposure on
expenses incurred for its Canadian operations. The Forwards obligate the Company
to sell US dollars for Canadian dollars in the future at predetermined exchange
rates and are matched with anticipated future operating expenses in Canada. The
Forwards do not subject the Company to risk from exchange rate movements because
gains and losses on such contracts offset losses and gains on exposures being
hedged. The counterparties to the Forwards are multinational commercial banks
and, therefore, the credit risk of counterparty non-performance is low.

During the fourth quarter fiscal 2004, the Company purchased Forwards to buy
$35.0 million Canadian dollars in the next three months at an average exchange
rate of 1.3793. All of the Forwards have become favourable to the Company since
their inception and have a fair value of $1.3 million at August 31, 2004.


3. ACQUISITIONS

On September 2, 2003, the Company acquired certain assets located in Taiwan and
China from AMI Technologies Corp., its exclusive sales organization for Taiwan
and China since 1992, for consideration of $3.1 million. The purchase price was
allocated to the net assets acquired, including intangible assets of $2.9
million, based on their relative fair values at the date of acquisition. The
useful life of the intangible assets acquired is approximately one year.

         (i)   Obligation under capital lease :

               on the building facility occupied by the Company in Markham,
               Ontario ("Building Facility"). The capital lease is denominated
               in Canadian dollars. As at August 31, 2004, the remaining amount
               outstanding on the capital lease was $18.0 million (Cdn. $23.7
               million).

        (ii)   Mortgage payable :
               On September 10, 2002, Commerce Valley Realty Holding Inc.
               ("CVRH"), a joint venture in which the Company has a 50 per cent
               ownership interest, entered into a mortgage agreement with a
               lender to finance the Building Facility. The Company's
               proportionate share of the mortgage as at August 31, 2004
               amounted to $11.6 million (Cdn. $15.2 million). The mortgage has
               a repayment term of 12 years and is denominated in Canadian
               dollars.


7. GUARANTEE

The Company and other owners of CVRH have jointly and severally provided a
guarantee for the mortgage payment of the Building Facility. In the event that
CVRH is unable to meet the underlying mortgage payment to the lender, the
Company and other owners of CVRH will be jointly and severally responsible under
this guarantee.

In addition, the Company posted a letter of credit in the amount of $2.3 million
(Cdn. $3.0 million) in favour of CVRH. CVRH has assigned this letter of credit
to the exclusive benefit of the lender as additional security of the mortgage.
The letter of credit has a term of 5 years and will expire on November 5, 2007.
In the event of a lease default by the Company, the proceeds of the letter of
credit will be paid to the lender.




                                                                        16 of 26

      ============================================================== ========== =========== =========== ============





     (i)   Settlement of class action lawsuits:

           On February 7, 2003, the Company announced that it had reached an
           agreement for the full and complete settlement of all remaining
           claims alleged in the shareholder class action lawsuits filed in May
           2001 in the United States District Court for the Eastern District of
           Pennsylvania for a cash payment of $8.0 million. This litigation
           relates to alleged misrepresentations and omissions made by the
           Company and certain directors and officers during a period preceding
           its May 2000 earnings warning. The terms of the Stipulation and
           Agreement of Settlement received final court approval on April 28,
           2003 and included no admission of liability or wrongdoing by the
           Company or other defendants. No party timely appealed from the
           Court's order.

           During the fourth quarter of fiscal 2003, the Company received $3.3
           million from its insurer as its contribution towards the settlement.

     (ii)  Regulatory matters:

           In January 2003, the Company announced that Staff of the Ontario
           Securities Commission ("OSC") had filed a Notice of Hearing and
           Statement of Allegations ("Notice") in relation to the Company and
           others. The Notice alleged that the Company failed to disclose
           information concerning the shortfall in revenues and earnings that
           occurred in the third quarter of fiscal 2000, as required by the
           listing rules of the Toronto Stock Exchange. The Notice also alleged
           that the Company made a misleading statement to Staff of the OSC in
           August 2000 regarding the events leading up to the disclosure on May
           24, 2000 of the shortfall. Seven individuals were also named in the
           Notice. The Notice alleged that six of these individuals, including
           K.Y. Ho, the then Chairman and Chief Executive Officer of the
           Company, engaged in insider trading contrary to the Securities Act.
           The hearing originally set for February - March 2004 has been
           rescheduled to October - November 2004.




                                                                        17 of 26

             (a)  During the second quarter of fiscal 2003, the Company
                  announced the closure of ATI Technologies (Europe) Limited
                  ("ATEL"), its subsidiary in Dublin, Ireland and recorded a
                  pre-tax charge of $2.8 million. The charge included a $1.4
                  million write-down of the building facility, to estimated fair
                  value less cost to sell. The Company completed the major
                  components of the exit plan for ATEL in July 2003.

                  During the first quarter of fiscal 2004, the Company was able
                  to sell the building facility at a higher price than
                  originally estimated resulting in a recovery of $0.5 million
                  from the restructuring charge. The Company also paid out the
                  remaining cash portion of the restructuring charge of $0.5
                  million during the same quarter.

            (b)   During the fourth quarter of fiscal 2003, the Company decided
                  to discontinue the operations of ATI Research GmbH, its FireGL
                  product division located in Starnberg, Germany, in order to
                  consolidate its research and development activities. As a
                  result, the Company recorded a pre-tax charge of $3.8 million
                  for the quarter pertaining to the closure of ATI Research
                  GmbH.

                  During the fourth quarter of fiscal 2004, the Company
                  recovered $0.2 million relating to the restructuring charge of
                  ATI Research GmbH.

                  During the three months and twelve months ended August 31,
                  2004, the Company made cash payments of $0.6 million and $3.5
                  million respectively relating to the pre-tax charge setup in
                  the fourth quarter of fiscal 2003. The Company completed the
                  major components of its exit plan for ATI Research GmbH in
                  December 2003. The remaining balance relates to unpaid
                  facility costs and legal fees.

8. OTHER CHARGES (CONTINUED)

     (iv) Lease exit charge (recovery):

          During the second quarter of fiscal 2003, the Company determined
          that it would exit the two leased properties located in Markham,
          Ontario. As a result, the Company recognized the fair value of the
          future net costs related to the leases in the amount of $2.4 million
          as a charge for the second quarter.

          During the fourth quarter of fiscal 2003, the Company recorded an
          additional charge of $0.3 million related to the exit costs of the
          above-mentioned lease properties due to a change in estimate of the
          fair value of the future net costs.

          During the second quarter of fiscal 2004, the Company determined that
          it would re-occupy one of the two leased properties due to an
          expansion of business. This resulted in a reduction of the previously
          accrued exit charge liability in the amount of $0.6 million for the
          quarter.

          During the third quarter of fiscal 2004, the Company determined that
          it would re-occupy the remaining leased property resulting in a
          reduction of the previously accrued exit charge liability of $0.9
          million.

      (v) Settlement of patent litigation with Cirrus Logic, Inc.:

          Subsequent to the year end of fiscal 2003, the Company and Cirrus
          announced that they had entered into a cross-license agreement and
          had settled all outstanding litigation between the Companies related
          to certain patent infringement lawsuits.

          Under the settlement agreement, all outstanding claims and
          counterclaims in the lawsuits between the Company and Cirrus were
          dismissed. In connection with the settlement, Cirrus would transfer to
          the Company a portion of its patent portfolio relating to the former
          graphics products group of its PC products division, a business that
          Cirrus exited several years ago, for a cash payment of $9.0 million
          from the Company.

12. STOCK-BASED COMPENSATION (CONTINUED)

     (i) Stock options (continued)

         For purposes of pro forma disclosures, the estimated fair value of the
         options is amortized to expense on a straight line basis over the
         options' vesting period.

   (ii)  Restricted share units

         During the first quarter of fiscal 2004, the Company adopted a plan to
         grant restricted share units ("RSUs") as part of its overall
         stock-based compensation plan. Under this plan, certain employees will
         receive an award in the form of an RSU. Each RSU entitles the holder to
         receive one common share on the vesting date of the RSUs. The RSUs vest
         on each anniversary of the grant in equal one-third instalments over a
         vesting period of three years. Stock-based compensation, representing
         the underlying value of $14.17 per common share of the Company at the
         date of grant of the RSUs, is being recognized evenly over the
         three-year vesting period. On the vesting dates, the RSUs are settled
         by the delivery of common shares of the Company to the participants
         except for the participants residing outside of North America who will
         receive cash equivalent market value of the shares. Grants of RSUs to
         participants residing outside of North America are accounted for using
         variable plan accounting whereby the value of the RSUs and its related
         amortization are adjusted based on the underlying value of the
         Company's common shares at the end of each fiscal quarter. As at August
         31, 2004, there were 1,514,450 RSUs awarded and outstanding of which
         none were vested.

         The issuance of RSUs replaced the annual grant of options for the 2003
         calendar year. In addition, a one-time cash payment of $7.8 million was
         also awarded to the non-executive employees who were eligible for the
         RSU plan during the first quarter of fiscal 2004. The full amount of
         the cash payment was expensed in the first quarter. The total expenses
         by functional areas incurred for the three months and twelve months
         ended August 31, 2004 pertaining to the cash payment and amortization
         of RSUs are as follows:

          -------------------------------- ------------------ -------------------




       During 2004, the Company advanced $22.1 million to the trustee of the RSU
       plan to enable the trustee to purchase the Company's common shares in the
       open market. At August 31, 2004 1,467,304 shares are being held by the
       trustee in order to deliver such shares to the participants on the
       vesting of the RSUs.

       The cost of the purchase of these shares is classified as treasury stock
       and presented as a reduction of shareholders' equity in the Company's
       consolidated balance sheet.

12. STOCK-BASED COMPENSATION (CONTINUED)

    (iii) Deferred share units

          During the second quarter of fiscal 2004, the Company established a
          plan to grant deferred share units ("DSUs") to its non-management
          directors. Under this plan, the directors will receive DSUs, in
          addition to cash payments, as part of their annual compensation
          package. A DSU is a unit equivalent in value to one common share of
          the Company based on the five-day average trading price of the
          Company's common shares on the Nasdaq Stock Market (the "Weighted
          Average Price") immediately prior to the date on which the value of
          the DSU is determined. DSUs may be redeemed following termination of
          Board service, and prior to the end of the year following departure
          from the Board based on the Weighted Average Price at the time of
          redemption. Alternatively, a director may elect to receive RSUs in
          lieu of DSUs provided the market value of his holdings in the
          Company's common stock equity is greater than $350,000. As at August
          31, 2004, there were 92,082 DSUs outstanding of which 75,155 were
          vested.

          As of the date of the grant, the fair value of the DSUs outstanding,
          being the fair market value of the Company's common shares at that
          date, will be recorded as a liability on the Company's balance sheet
          and will be amortized over the one year vesting period of the DSU. The
          value of the DSU liability will be adjusted to reflect changes in the
          market value of the Company's common shares. The expenses for this
          quarter and the twelve months ended August 31, 2004 relating to DSUs
          granted to the directors for services rendered were $0.03 million and
          $1.2 million respectively.

13. U.S. GAAP (CONTINUED)

     (i)  Under U.S. GAAP, options granted after January 18, 2001 with an
          exercise price denominated in a currency other than the currency of
          the primary economic environment of either the employer or the
          employee, should be accounted for under the variable accounting
          method. Under Canadian GAAP, there is no equivalent requirement. There
          were no such options granted after February 28, 2002.

     (ii) Under U.S. GAAP, the intrinsic value of the stock options issued under
          an incentive plan entered into in July 2002 is calculated as the
          increase in the Company's stock price between the grant date and the
          date on which all the conditions of the specified business arrangement
          were determined to have been met. The compensation expense is
          recognized over the vesting period of the options. Under Canadian
          GAAP, there is no equivalent requirement.
