           ATI reports revenues of $463 million for the second quarter
             Revenues up 48% relative to second quarter fiscal 2003

MARKHAM, ON - March 31, 2004 - ATI Technologies Inc. (TSX: ATY, NASDAQ: ATYT)
today announced its financial results for the second quarter of fiscal 2004,
ended February 29, 2004. ATI reported revenues(1) of $463.3 million, a 47.8%
increase relative to the second quarter of fiscal 2003. Gross margin rose to
34.8% - almost six percentage points higher than the same quarter a year ago.
Net income(2) per share was $0.19 for the quarter compared to a loss of $0.04
per share last year. ATI's cash position increased $88.5 million during the
quarter to $468.5 million as of February 29, 2004.

Technology leadership across all product categories enabled ATI to deliver a
strong second quarter performance. We continued to make broad-based unit gains
in the desktop mainstream markets and saw growth in our DTV business relative to
the first quarter.

"We continue to deliver strong financial performance driven by the strength and
breadth of our product lines," said K.Y. Ho, Chairman and Chief Executive
Officer, ATI Technologies Inc. "Product and technology leadership continues to
be the foundation of our success and we see tremendous opportunities in the
future to expand our market share and accelerate our momentum in the consumer
electronics market."

Recently, we announced a strategic collaboration with Qualcomm Inc., a major
supplier of cell phone technology. This, together with the partnership with SK
Telecom announced in March of this year and current design wins with Motorola,
cement ATI's leadership position in cell phone graphics.

Outlook

We believe we are well-positioned for the back half of fiscal 2004 based on the
strength of our product roadmap, including new products that are to be announced
shortly; the expected transition of the PC industry to the PCI Express
interconnect in the second calendar quarter, where we have significant
opportunity to gain market share in the desktop discrete market; continued
relative strength of the PC market; as well as continued momentum in the
Consumer business.

As a result of these factors, ATI expects strong revenues for the third quarter,
despite it being traditionally the industry's weakest, and to be in the range of
$440 - $480 million. Gross margin, as a percentage of revenues, is expected to
be in the upper half of its target range of 32 - 35%, and about the same level
as the second quarter. Operating expenses, excluding amortization of intangible
assets and other charges, are expected to increase 5 - 10% relative to the
second quarter due to increased prototyping expense as well as staffing to
support new customer programs - particularly in the Consumer business.

Financial Results Analysis

Revenues
- --------

In the second quarter of fiscal 2004, our revenues grew by 47.8% compared with
the same period a year ago.

Revenues were $463.3 million in the second quarter compared to $313.5 million
for the same quarter last year. For the first six months, revenues were up 43.8%
to $933.0 million compared to $648.9 million for the same period last year.

Our PC revenues increased by about 35% for the second quarter of fiscal 2004
relative to the same period a year ago. All product categories, including
desktop and notebook discrete, as well as integrated graphics processors (IGPs)
contributed to this increase. Our consumer product revenues increased eight-fold
with our Imageon(TM) products being the key driver of growth in this period.

PC revenues increased over 35% and consumer product revenues increased ten-fold
in the first six months of fiscal 2004 compared with the same period a year ago.

Increasing shipments to add-in-board (AIB) manufacturers were a major driver of
PC revenue growth. AIB channel revenue approximately doubled for the second
quarter and year-to-date relative to the same periods a year ago.

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

Gross margin in the second quarter was 34.8%.

Our gross margin improved by almost six percentage points compared to the second
quarter of fiscal 2003. Year-to-date our gross margin was 35.4% compared with
28.0% for the same period a year ago - a gain of 7.4 percentage points.




Desktop discrete product margins were the main contributor to the increase of
gross margin on a quarter-over-quarter and year-to-date basis. The increase in
our gross margin in desktop discrete was a result of strength across all our
desktop products, and particularly in the mainstream to enthusiast segments.
Cost reduction programs and inventory management improvements are also
contributing to the strength in our gross margin.







                                                                       6 of 29





Our reported gross margin is comprised of product gross margin as well as
royalty income associated with our Nintendo business and "non-recurring
engineering" (NRE) payments associated with our development contracts. Both our
royalty income from Nintendo as well as NRE are reported in our segmented
reporting under "Other". While royalty income from Nintendo is recorded as 100%
gross margin, NRE payments for console products are matched against the related
cost of development. Please see Note 10 to the consolidated financial statements
for further information on our segmented reporting.

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

Our operating expenses, excluding the amortization of intangibles and other
charges, were $103.2 million, an increase of 28.6% over the second quarter in
fiscal 2003. Year-to-date operating expenses, excluding the amortization of
intangibles and other charges, were $209.8 million, up 31.0%, from $160.1
million for the same period a year ago.

About 40% of the increase in operating expenses quarter-over-quarter and half of
the increase on a year-to-date basis was a result of incentive-based
compensation and the foreign exchange impact of a higher Canadian dollar
relative to the U.S. dollar.

Increased advertising as well as increased staffing to support higher sales
levels were the key factors in the higher sales and marketing expense on both a
quarter-over-quarter and a year-to-date basis. Higher operating expenses were
also due to an increase in administration costs resulting from the higher
Canadian dollar and incentive-based compensation and a changed methodology for
board compensation. Please see Note 11 to the consolidated financial statements
for further information on the board compensation change.








                                                                       7 of 29



Research and development costs were also higher at 25.5% quarter-over-quarter
and 28.5% on a year-to-date basis. In addition to the higher Canadian dollar and
incentive-based compensation costs, R&D expenses have risen in both comparable
periods due to increased staffing and technology costs required to promote
advances in our growing product line. These increases were largely attributable
to increased staffing in software and our handheld business, as well as
prototyping costs and CAD-related licensing fees.

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

We recorded a recovery of other charges totaling $0.2 million in the second
quarter. This compares to other charges of $16.0 million for the second quarter
last year. Other charges in fiscal 2003 were 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 the European manufacturing
operations and a lease termination charge related to surplus space in leased
buildings, which were not a factor this year. Please see Note 7 to the
consolidated 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 3 to the consolidated financial statements.

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

Our interest and other income was $1.9 million in the second quarter of 2004
compared with $0.6 million in the second quarter last year. The increase in
interest and other income for the second quarter compared to the same period a
year ago is primarily due to an insurance recovery related to the earthquake in
Taiwan in September 1999, as well as an increase in interest income due to a
substantially higher cash position.

For the first six months of 2004, interest and other income was $0.1 million
compared with $1.1 million in the same period in 2003. The lower income for the
first six months of 2004 was mainly due to the write off of capital assets in
the first quarter of this year. This was partially offset by the insurance
recovery and increased interest income noted above.






                                                                       8 of 29




Net Income (Loss)
- -----------------

Net income increased to $47.6 million in the second quarter of 2004 from a loss
of $9.4 million in same quarter last year. We generated net income of $95.0
million for the first six months of the current fiscal year compared with a loss
of $2.1 million in 2003.

The increase in net income in both comparable periods was largely the result of
increasing revenues, higher margins and improving operating expense leverage, as
well as the decrease in other charges described above.

Liquidity and Financial Resources

Inventory levels increased to $228.7 million at the end of the second quarter up
from $176.5 million at August 31, 2003, but were about flat relative to the
first quarter of this year. In general terms, this inventory level reflects the
higher volume of sales generated in the quarter, and in line with our goal of
keeping inventory in the 60-day range.

Accounts receivable were down by $13.0 million from the year ended August 31,
2003 to $221.6 million at the end of the second quarter. Days sales of accounts
receivable were down to 48 days in the second quarter compared to 50 days in the
first quarter of 2004 due to the timing of product sales during the quarter.

As of February 29, 2004 we had working capital of $549.0 million compared to
$430.3 million at August 31, 2003. Cash flow from operations was $75.2 million
in the second quarter. We had cash and short-term investments of $468.5 million
at the end of the second quarter, up from $350.7 million of cash recorded at end
of fiscal 2003. Our cash position increased mainly as a result of increasing
earnings in the first two quarters of the fiscal year.

Intangible assets other than goodwill declined slightly to $8.6 million at the
end of the second quarter, from $8.8 million at year-end.

The principal business activities of ATI Technologies Inc. (the "Company") are

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

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 six months ended
February 29, 2004 are not necessarily indicative of the results to be expected
for the full year.

The Company experiences seasonal variation in revenues with revenues being the
highest in the first quarter.

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 first and second quarter of Fiscal 2003 is as
follows:

       in Canadian dollars.


6.     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

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.







                                                                        17 of 29

(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 Chairman and Chief Executive
       Officer of the Company, engaged in insider trading contrary to the
       Securities Act. The hearing was set for February - March 2004 but the
       Respondents and OSC have agreed to adjourn the hearing to a date to
       be arranged by the Secretary of the Commission, which is expected to
       be in the Fall of 2004.






                                                                        18 of 29

       (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 last 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 six months ended February 29,
              2004, the Company made cash payments of $0.1 million and $2.8
              million respectively relating to the pre-tax charge set up in
              the fourth quarter of fiscal 2003. The Company completed the
              major components of its exit plan for ATI Research GmbH in
              December 2003.

(iv)     Lease exit charge

         During the second quarter of fiscal 2003, the Company determined that
         it would exit certain leased properties located in Markham, Ontario.

         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 a leased property, which the Company had exited in
         the second  quarter of fiscal 2003,  due to an expansion of business.
         It  resulted  in a  recovery  of exit  charge  in the  amount of $0.6
         million for the quarter.

11.      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 February 29, 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 six months ended
         February 29, 2004 pertaining to the cash payment and amortization of

11.      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. Upon termination of Board service, the director
          will be able to redeem DSUs six months after his departure from the
          Board based on the Weighted Average Price at the time of redemption.
          However, the director must redeem his DSUs by the end of December in
          the year following the year of departure from the Board.
          Alternatively, the director may elect to receive RSUs in lieu of DSUs
          provided that the market value of his holdings in the Company's common
          stock equity exceeded $350,000.

          As of the date of the grant, the fair value of the DSU, 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
          expense recorded in the quarter of $0.9 million related to DSUs
          granted in December 2003 for services rendered during the period
          February 1, 2003 to January 31, 2004.




                                                                        25 of 29

(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.
