           ATI reports record revenues of US$491.5 million in Q3
             Net income triples from year earlier

MARKHAM,  ON - June 24, 2004 - ATI Technologies  Inc. (TSX: ATY,  NASDAQ:  ATYT)
today announced record  quarterly  revenues as a result of major sales increases
in key market segments.

ATI reported revenues(1) of $491.5 million for the third quarter of fiscal 2004
(ended May 31, 2004), a 38.2% increase over the third quarter a year earlier.
Gross margin was up 2.7 percentage points to 35.3% over the same period. Net
income(2) per share was $0.19 for the quarter compared to $0.06 per share last
year. ATI's cash position increased $39.6 million during the quarter to $508.0
million as of May 31, 2004.

"These results confirm that ATI clearly has the graphic technologies of choice,"
said K.Y. Ho, Chairman of ATI. "Over the past year, ATI made significant sales
gains in the add-in-board channel, as well as notebook, handheld chip and
digital television (DTV) sectors, led by a very competitive portfolio of
products."

"Delivering on PCI Express, a key industry inflection point, provided us with
nearly a clean sweep of tier-one OEM design wins," said David Orton, Chief
Executive Officer of ATI. "Our corporate strategy put us in the right place at
the right time, just as it did with graphics on cell phones, the transition to
digital television and the move to high-end graphics on notebooks. We've
anticipated the visual age of computing, and now we're delivering on that."

Outlook

We believe we are  well-positioned for the fourth quarter of fiscal 2004 and the
first half of fiscal 2005 based on the  expected  market  share  momentum in the
desktop discrete business, the continued strength of the PC market and growth of
our consumer business.


As a result of these factors, ATI currently expects revenues for the fourth
quarter to be in the range of $510 - $550 million. Based on the ramp of new
products in the fourth quarter, gross margin, as a percentage of revenues, is
expected to return to the upper half of our target range of 32 - 35%. Operating
expenses, excluding amortization of intangible assets and other charges, are
expected to increase approximately 5% relative to the third quarter.

Financial Results Analysis

Revenues
- --------

Third quarter revenues of $491.5 million grew by 38.2% from $355.7 million in
the same period a year ago. Revenues for the first nine months of fiscal 2004
were $1.42 billion, 41.8% more than the $1.00 billion achieved in the first
three quarters of fiscal 2003. Revenues from our consumer products - handheld
and DTV - approached 10% of total revenues in the quarter, with PC product
revenues comprising most of the balance.

The gains for both the third quarter and year-to-date were largely driven by
sales increases in desktop chips in the add-in-board (AIB) channel, as well as
in mobile, handheld chip, and digital television (DTV) sectors.

AIB growth was a result of our very competitive portfolio of products and
greater market penetration through our growing number of relationships with AIB
partners. Third quarter discrete mobile revenues were up more than 50%
quarter-over-quarter and up almost 50% year-to-date. Integrated mobile revenues
grew more than 20% on a year-to-date basis, based on both notebook market growth
and increasing penetration of integrated graphics processors (IGPs) in the
notebook market. Revenues from handheld chips were up substantially
quarter-over-quarter and year-to-date driven by growth in our cell phone
business. This growth was the result of design wins in high volume color and
camera phones. Our DTV chip revenues, driven by a significant number of design
wins with leading television and set-top box manufacturers, were up
approximately four times both quarter-over-quarter and on a year-to-date basis.

The royalty revenue we received from Nintendo for our graphics technology used
in their GAMECUBE products also increased in the third quarter of 2004 compared
with the same period a year ago.


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

Our gross margin of 35.3% this quarter slightly exceeded the high-end of our
current target range of 32 - 35%. Gross margin for the quarter was up 2.7
percentage points from 32.6% in the same period a year ago. Year-to-date, gross
margin was 35.4%, an improvement of 5.8 percentage points from the first three
quarters of 2003.









                                                                       6 of 28



Our product gross margin was 35.3% in the third quarter, up 3.2 percentage
points quarter-over-quarter. Year-to-date, product gross margin was 35.2%, an
improvement of 7.1 percentage points from the first three quarters of 2003.

The improvements for both the third quarter and year-to-date resulted from
increased margins in desktop discrete chips, as well as the contribution of our
consumer business.

Our reported gross margin is comprised of product gross margin, plus royalty
income associated with our Nintendo business, and "non-recurring engineering"
(NRE) revenues and cost associated with our development contracts. Both our
royalty income from Nintendo, as well as NRE, 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
- ------------------

The foreign exchange impact of a stronger Canadian dollar relative to the U.S.
dollar - which particularly affects costs associated with our headquarters
located in Markham, Canada - accounted for almost 20% of the total operating
expense increase quarter-over-quarter and just over 20% of the increase in
expense year-to-date.

Selling and marketing expenses increased by 27.3% quarter-over-quarter to $32.7
million, and by 33.1% on a year-to-date basis to $92.3 million. Other than the
foreign exchange impact, the additional costs related to increased staff for
sales and technical sales support, an increased investment in advertising
designed to improve ATI's brand awareness, as well as increased marketing
activities to support product launches and participation in industry trade
shows.

Administrative expenses were up 24.0% quarter-over-quarter to $12.8 million, and
by 28.6% on a year-to-date basis to $37.1 million as a result of increased
staffing to support our infrastructure growth and increased incentive based
compensation.





                                                                       7 of 28



Research and development expenses increased 24.5% quarter-over-quarter to $66.9
million, and by 27.1% year-to-date to $192.8 million. Other than the foreign
exchange impact, this increase was largely a result of increased prototyping
costs and other engineering related expenses associated with the introduction of
our new portfolio of PCI Express products. These efforts have led to a number of
design wins which we believe will result in market share gains in our desktop
discrete business. Increased staffing to support these and other growth programs
also added to R&D costs.


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

We recorded a recovery of other charges totaling $0.5 million both in the third
quarter and year-to-date. Other charges of $2.3 million for the third quarter
last year, and $18.3 million for the first nine months of 2003 related to the
settlement of a U.S. class action law suit, costs incurred in connection with a
regulatory matter, restructuring charges related to the closure of our European
manufacturing operations, and lease termination charges. 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 and other charges. 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 (Expenses)
- ------------------------------------

Our interest and other income was $1.3 million in the third quarter of 2004 and
$1.4 million year-to-date, compared with charges of $1.4 million and $0.2
million respectively, for the comparable periods in fiscal 2003. Interest and
other income in 2004 was derived principally from interest on our cash balance.


Loss on investments
- -------------------

We recorded a $1.3 million loss on investments in the third quarter to reflect
an other than temporary decline in the value of an investment.






                                                                       8 of 28



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

Net income increased by more than three times to $48.6 million in the third
quarter of 2004 from $15.0 million in same quarter last year. For the first
three quarters of 2004, net income was $143.6 million, more than 11 times the
$12.9 million recorded in the first nine months of fiscal 2003.

The higher margins we have achieved in the third quarter and first nine months
of 2004, and the substantially increased sales, in both periods, account for
most of the increase in net income.


Liquidity and Financial Resources

Third quarter inventory levels increased by 10.5% over the second quarter of
2004 to $252.8 million. Inventory is up 43.2% since the end of the last fiscal
year, August 31, 2003. Most of the increase, over both periods, is a direct
result of our substantially increased sales, as well as the product ramp for new
desktop products.

Accounts receivable increased by 33.9% during the third quarter to $296.6
million. Accounts receivable are up 26.5% from the year ended August 31, 2003.
The increase was largely due to the timing of sales during the quarter.

Accounts payable increased by 32.7% to $269.7 million over the second quarter of
2004. Accounts payable are up 41.1% from the year ended August 31, 2003. Most of
the increase is a direct result of timing of inventory purchases of new product.

Deferred revenue for the third quarter was $29.3 million, down $7.9 million from
the second quarter and down $8.3 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 May 31, 2004 we had working capital of $613.7 million compared to $430.3
million at August 31, 2003. Cash flows from operations were $36.6 million in the
third quarter. Our cash position was $508.0 million at the end of the third
quarter, up from $350.7 million at the end of fiscal 2003. Our cash position
increased mainly as a result of increased earnings in the first three quarters
of the fiscal year.







                                                                       9 of 28



We believe that cash flows from operating activities, together with our cash
position and borrowing capacity under our credit facilities, are sufficient to
fund currently anticipated working capital, planned operating and capital
expenditures and debt service requirements for the next 12 months.

                                                                       14 of 28

(Unaudited)


The principal business activities of ATI Technologies Inc. (the "Company") are
the design, manufacture and sale of innovative 3D graphics and digital media
silicon solutions. The Company markets its products to original equipment
manufacturers, system builders, distributors and retailers primarily in North
America, Europe and the Asia-Pacific region.


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 current quarter:

(a)  The Company has adopted CICA Accounting Guideline No. 13, Hedging
     Relationships, for its derivative instruments. During the quarter, the
     Company engaged in activities to purchase certain derivative financial
     instruments, principally forward foreign exchange contracts, 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 forward foreign exchange contracts to hedge
     anticipated expenses pertaining to its operations in Canada. These
     instruments are not recognized in the consolidated financial statements on
     inception. Foreign exchange gains and losses on these contracts are
     deferred off-balance sheet and recognized as an adjustment of 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. The results of operations for the three months and nine months ended
May 31, 2004 are not necessarily indicative of the results to be expected for
the full year.









                                                                       15 of 28

1.       SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

During fiscal 2003, the Company reviewed its revenue recognition accounting
policy as it is applied to the shipment of products to its customers. Following
this review, the Company corrected its revenue recognition accounting policy by
revising the timing of when revenue is recognized to more clearly identify the
point in the shipping process when the risks and rewards of ownership have been
transferred to the customer. This change, and the related income tax effect,
have been applied retroactively. The financial statements presented for
comparative purposes have been restated to give effect to this change.

The impact of this change on the three months and nine months ended May 31, 2003
was as follows:

2.       FINANCIAL INSTRUMENTS

The Company enters into forward foreign exchange contracts to hedge its foreign
currency exposure on the expenses incurred for its Canadian operations. The
forward foreign exchange contracts oblige the Company to sell US Dollars for
Canadian dollars in the future at predetermined exchange rates. The forward
foreign exchange contracts are matched with anticipated future operating
expenses in Canada. The forward foreign exchange contracts 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 forward foreign exchange contracts are multinational commercial banks
and, therefore, the credit risk of counterparty non-performance is low.

At May 31, 2004, the Company had purchased forward foreign exchange contracts to
buy $33 million Canadian dollars in the next two and a half months at an average
exchange rate of 1.3749. All of the forward foreign exchange contracts have
become favourable to the Company since their inception and have a fair value of
$0.2 million at May 31, 2004.









                                                                       16 of 28

(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
        Commission in August 2000 regarding the events leading up to the
        disclosure on May 24, 2000 of the shortfall. Seven individuals are
        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 the Fall of 2004.

          (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 in Dublin, Ireland
                  to 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 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 three months and nine months ended May 31, 2004,
                  the Company made cash payments of $0.1 million and $2.9
                  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
                  severance and facility costs.




                                                                       20 of 28

8.         OTHER CHARGES (CONTINUED)

(iv)       Lease exit charge

           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, which the
           Company had exited in the second quarter of fiscal 2003, due to an
           expansion of business. This resulted in a recovery of exit charge 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 which the Company
           had exited in the second quarter of fiscal 2003, resulting in a
           recovery of exit charge of $0.9 million.

         The weighted average estimated fair values at the date of grant for the
         stock options granted for the three months and nine months ended May
         31, 2004 were $9.15 and $8.93 per share respectively. No options were
         issued during the three months ended May 31, 2003 and the weighted
         average estimated fair value of the stock options granted for the nine
         months ended May 31, 2003 was $2.65. The "fair value" of each option
         granted was estimated on the date of the grant using the Black-Scholes

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 over the options' vesting period.

(ii)     Restricted share units

         During the first quarter of fiscal 2004, the Company announced that it
         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 May 31, 2004, there were 1,556,239 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 nine months ended
         May 31, 2004 pertaining to the cash payment and amortization of RSUs
         are as follows:

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


         During the first quarter of fiscal 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. These shares
         are being held by the trustee in order to deliver such shares to the
         participants on the vesting dates of the RSUs.

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.

          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 vesting period of the DSU, which is
          expected to be one year. The value of the DSU liability will be
          adjusted to reflect changes in the market value of the Company's
          common shares. The expenses incurred for this quarter and the nine
          months ended May 31, 2004 related to DSUs granted to the directors for
          services rendered were $0.3 million and $1.2 million respectively.




                                                                       26 of 28

(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.
