     ATI Reports 34 Per Cent Sequential Revenue Increase in First Quarter

    Rapidly expanding position in enthusiast, mainstream and value markets

Markham, Ontario - December 18, 2002 - ATI Technologies Inc. (TSX: ATY,
NASDAQ: ATYT), a world leader in the design and manufacture of innovative 3D
graphics and digital media silicon solutions, today announced its financial
results for the first quarter of its 2003 fiscal year ended November 30, 2002.

Revenues for the first quarter were $322.0 million, up 34.5 per cent from
$239.5 million in the fourth quarter of fiscal 2002, and up 28.8 per cent from
$250.0 million in the first quarter of fiscal 2002. Gross margins were 27.3
per cent, down from 30.1 per cent in the fourth quarter of fiscal 2002.
Operating expenses, excluding amortization of intangible assets, increased to
$79.6 million from $70.1 million in the previous quarter.

Net income for the first quarter was $5.0 million or $0.02 per share compared
to a net loss of $32.2 million or $0.14 per share for the fourth quarter of
2002 and a net loss of $10.3 million or $0.04 per share for the same period a
year ago. Adjusted net income(1) for the quarter was $7.0 million or $0.03 per
share compared to $2.4 million or $0.01 per share for the previous quarter,
and $10.4 million or $0.04 per share for the same period a year ago.

(/1/)Adjusted net income excludes the after-tax effect of gain (loss) on
investments (net), amortization of goodwill and intangible assets related to
the Company's acquisitions, and the deferred tax recovery of future tax
liability pertaining to goodwill and intangible assets acquired. Each of these
items has been excluded from adjusted net income as they are not considered to
be part of the Company's normalized ongoing operations. While the Company
recognizes that adjusted net income does not have any standardized meaning
described by generally accepted accounting principles, or GAAP, and that its
adjusted net income calculation cannot be used as a comparison to other
companies' financial performance, ATI believes that its adjusted net income
more appropriately reflects the Company's operating performance. Please see
the table titled "Adjusted Net Income - Reconciliation" in Management's
Discussion and Analysis of Interim Financial Results in this news release for
the reconciliation between adjusted net income and net income which is
determined in accordance with GAAP. All dollar amounts are stated in U.S.
dollars unless otherwise noted. All per share amounts are stated on a fully
diluted basis unless otherwise noted.


                                                                        4 of 22

"We were pleased with the strength of our PC business in our first quarter,"
said David Orton, President and Chief Operating Officer, ATI Technologies Inc.
"We obtained key design wins in every product category and our product
strength helped ATI to gain share in all major channels and geographies. We
continue to invest in R&D in order to maintain the momentum that we have
created."

In the first quarter, the RADEON(TM) 9700 and RADEON(TM) 9000 family of
products along with ATI's integrated graphics products, drove revenue growth.
ATI's add-in-board partners delivering RADEON(TM)-based technology to the
system builder market also contributed to the Company's revenue growth this
quarter.

"Over the last few quarters, ATI has achieved undisputed technology leadership
in PC graphics, and delivered compelling visual solutions to every market
segment," said K.Y. Ho, Chairman and Chief Executive Officer, ATI Technologies
Inc. "Moreover, ATI is committed to executing on an aggressive product roadmap
to deliver and expand our industry-leading visual processing solutions."

Outlook

Because of the seasonal strength in the first quarter, ATI believes that
revenues in the second quarter will be approximately 10 per cent lower than
the first quarter. During the second quarter, gross margins as a per cent of
revenues should improve somewhat, while total operating expenses are expected
to increase primarily due to research and development costs related to higher
prototyping expenses. Based on these factors, the Company is targeting to
achieve second quarter adjusted net income that is approximately the same as
the first quarter.

"Looking into the back half of the year, we are focusing on improving margins
in our PC business and realizing a contribution from our consumer business,
where a soft market has delayed the start of some of our customers' programs,"
said Terry Nickerson, Senior Vice President and Chief Financial Officer, ATI
Technologies Inc. "Our challenge is to translate our product strength and top-
line success into equal success on our bottom line."


                                                                        5 of 22

Operational Highlights

During the first quarter, ATI enjoyed rapid adoption of the RADEON(TM) 9700
and RADEON(TM) 9000 family of products by the OEM, system builder and retail
channels. The RADEON(TM) 9700 and RADEON(TM) 9700 PRO began shipping in the
flagship models of the major OEMs worldwide including Dell, eMachines,
Fujitsu, Founder, Gateway, HP and NEC. ATI continued to maintain a strong
position in the notebook market during the quarter with more than 20 design
wins for the MOBILITY(TM) RADEON(TM) 9000. Major design wins included models
from Dell, HP and Apple.

Other operational highlights during the quarter:

  .  The RADEON(TM) 9000 PRO began shipping in consumer desktop PCs from
     major OEMs including Apple, Fujitsu Siemens, HP and NEC.

  .  ATI set a new standard for the performance mainstream desktop market
     with the introduction of the RADEON(TM) 9500 and RADEON(TM) 9500 PRO.

  .  ATi delivered the ultimate visual and home entertainment experience on a
     PC with the introduction and shipment of the ALL-IN-WONDER(R) 9700 PRO.

  .  ATI's FIRE GL(TM) X1 workstation graphics board - based on the
     RADEON(TM) 9700 visual processing unit - began shipping into Dell's
     high-end workstation, the Precision 650.

  .  ATI had a successful ramp of its integrated graphics chip products in
     the value segment of the PC market with the RADEON(TM) IGP 320M and IGP
     340M.

  .  ATI broadened its reach into Asia-Pacific with design wins with Legend
     and Founder - the top computer manufacturers in China.

  .  ATI won the PC Magazine Award for Technical Excellence for the
     RADEON(TM) 9700 PRO.


                                                                        6 of 22

Management's Discussion and Analysis of Interim Financial Results

Revenues

Revenues for the first quarter were $322.0 million, up 34.5 per cent from
$239.5 million in the fourth quarter of fiscal 2002, and up 28.8 per cent from
$250.0 million in the first quarter of fiscal 2002. Among the factors
contributing to this increase in revenues were a broad-based market demand for
ATI's visual processing units led by the RADEON(TM) 9700 and the RADEON(TM)
9000 product families and a strong launch into the value segment of the PC
market with ATI's new line of integrated chipset products.

Gross Margins

Gross margins for the first quarter were 27.3 per cent of sales compared to
30.1 per cent in the fourth quarter and 32.0 per cent in the same quarter a
year earlier. The decrease in gross margins sequentially and year-over-year
resulted primarily from the writedown in the inventory value of certain
products which was responsible for 3 percentage points of the decline.
Additionally, 2 percentage points of the decline can be attributed to a slower
transition in the implementation of cost reductions. Nintendo royalty
revenues, however, were stronger than expected. Although the Company believes
that gross margins should improve somewhat in the second quarter, it currently
does not expect to approach margins in its target range of 32 - 35 per cent
until the fourth quarter of fiscal 2003.

Operating Expenses

Operating expenses, excluding amortization of intangibles, were $79.6 million,
up 13.5 per cent from $70.1 million in the fourth quarter of fiscal 2002, and
up 15.1 per cent from $69.1 million for the first quarter of fiscal 2002. The
sequential and year-over-year quarterly increase in research and development
was largely due to higher costs related to prototyping, tools and licensing
fees. Higher variable selling costs due to increased revenues were responsible
for $2.5 million of the increase in selling and marketing expenses in the
first quarter compared to the fourth quarter of fiscal 2002.


                                                                        7 of 22

Total operating expenses decreased $20.9 million, or 20.1 per cent in the
first quarter to $82.8 million compared to the fourth quarter of fiscal 2002
and decreased 8.4 per cent for the same period a year earlier. These decreases
were largely the result of the adoption of the accounting policies relating to
the treatment of goodwill and intangible assets (CICA Handbook Section 3062)
somewhat offset by higher research and development as well as selling
expenses. The decrease in operating expenses compared to the fourth quarter of
2002 is also related to the fourth quarter writedown in the core technology
and goodwill associated with the prior acquisitions of intangible assets of
ArtX and Chromatic Research.

Net Income

Net income in the first quarter of fiscal 2003 was $5.0 million or $0.02 per
share compared to a net loss of $32.2 million or $0.14 per share for the
fourth quarter of fiscal 2002 and a net loss of $10.3 million or $0.04 per
share for the same quarter a year ago. The increase in net income compared to
the prior quarters is attributable to lower operating expenses resulting from
the adoption of the accounting policies relating to the treatment of goodwill
and intangible assets (CICA Handbook Section 3062) somewhat offset by higher
research and development and selling, marketing and administrative expenses.

Adjusted net income(/1/) for the quarter was $7.0 million or $0.03 per share
compared to $2.4 million or $0.01 per share for the previous quarter, and
$10.4 million or $0.04 per share for the same period a year ago. Significantly
higher revenues, offset somewhat by a decrease in gross margin per cent and
increased research and development expenses, drove the increase in adjusted
net income relative to the fourth quarter of 2002. The decrease in adjusted
net income for the quarter compared to the first quarter a year ago is a
result of decreased gross margin percentage realized on higher revenues and
increased research and development expenses.

(/1/)Adjusted net income excludes the after-tax effect of gain (loss) on
investments (net), amortization of goodwill and intangible assets related to
the Company's acquisitions, and the deferred tax recovery of future tax
liability pertaining to goodwill and intangible assets acquired. Each of these
items has been excluded from adjusted net income as they are not considered to
be part of the Company's normalized ongoing operations. While the Company
recognizes that adjusted net income does not have any standardized meaning
described by generally accepted accounting principles, or GAAP, and that its
adjusted net income calculation cannot be used as a comparison to other
companies' financial performance, ATI believes that its adjusted net income
more appropriately reflects the Company's operating performance. Please see
the table titled "Adjusted Net Income - Reconciliation" below for the
reconciliation between adjusted net income and net income which is determined
in accordance with GAAP.



                                                                        8 of 22

Liquidity and Financial Resources

ATI's cash used in operations was $31.0 million in the first quarter of fiscal
2003, compared to cash used in operations of $2.7 million in the fourth
quarter of fiscal 2002. The increase in cash used in operations during the
quarter was primarily a result of the increase in accounts receivable
associated with the strong revenue performance.

Inventory levels declined slightly to $172.4 million at the end of the first
quarter compared with $175.3 million at the end of the fourth quarter in spite
of a higher level of sales.

As of November 30, 2002, ATI had working capital of $381.5 million, compared
to $361.7 million at the end of the fourth quarter of fiscal 2002. The
Company's cash position was $200.1 million as of November 30, 2002, compared
to $236.9 million at August 31, 2002. The decline was largely due to an
increase in accounts receivable as a result of a sharp increase in sales in
the quarter.

Intangible assets other than goodwill declined to $16.4 million at the end of
the first quarter of fiscal 2003, from $21.9 million in the fourth quarter of
fiscal 2002. The decline in these assets was due to the continued amortization
of intangible assets of prior acquisitions. In addition, as a result of the
adoption of CICA Handbook Section 3062, the Company reclassified $2.3 million
relating to workforce from intangible assets to goodwill.

In the first quarter, ATI adopted the new accounting policies relating to the
treatment of goodwill and intangible assets (CICA Handbook Section 3062) and
therefore there will be no further amortization of goodwill. Goodwill, which
is associated primarily with the prior acquisition of ArtX, is currently
$190.1 million and will be tested for impairment on an annual basis.

Accounts receivable increased by $49.6 million during the quarter to $213.9
million. This increase was primarily due to the sharp increase in sales during
the quarter. Accounts payable declined by $3.1 million in the first quarter to
$169.0 million.


                                                                        9 of 22

Adjusted Net Income - Reconciliation

The table below presents adjusted net income and adjusted net income per
share, which excludes the after-tax effect of gain on investments,
amortization of goodwill(/1/) and intangible assets related to the Company's
acquisitions, and deferred tax recovery of future tax liability pertaining to
intangible assets acquired, related to the Company's acquisitions.

(Unaudited)

The principal business activities of ATI Technologies Inc. (the "Company") are
the design, manufacture and sale of 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 Asia-Pacific.

1. SIGNIFICANT ACCOUNTING POLICIES

The accompanying unaudited financial statements are prepared in accordance
with Canadian generally accepted accounting principles for interim financial
statements. These financial statements and notes related thereto should be
read in conjunction with the Company's most recent annual consolidated
financial statements, as at and for the year ended August 31, 2002.

These consolidated financial statements follow the same accounting policies
and methods of their application as the most recent annual consolidated
financial statements with the exception of the following:

(a) CICA Handbook Section 3870, Stock-based Compensation and Other Stock-based
    Payments:

  Effective September 1, 2002, the Company adopted Stock-based Compensation
  and Other Stock-based Payments in CICA Handbook Section 3870, which
  establishes standards for the recognition, measurement and disclosure of
  stock-based compensation and other stock-based payments made in exchange
  for goods and services provided by employees and non-employees. The
  standard requires that a fair value based method of accounting be applied
  to all stock-based payments to non-employees and to employee awards that
  are direct awards of stock, that call for settlement in cash or other
  assets or are stock appreciation rights that call for settlement by the
  issuance of equity instruments. However, the new standard permits the
  Company to continue its existing policy of recording no compensation cost
  on the grant of stock options to employees with the addition of pro forma
  information. The Company has applied the pro forma disclosure provisions of
  the new standard to awards granted on or after September 1, 2002. No
  restatement of prior periods was required as a result of the adoption of
  the new standard. Consideration paid by employees on the exercise of stock
  options is recorded as share capital. See Note 9 for the pro forma
  disclosure as required by this standard.

(b) CICA Handbook Section 1581, Business Combinations, and Section 3062,
    Goodwill and Other Intangible Assets:

  In September 2001, the CICA issued Handbook Sections 1581 "Business
  Combinations" and 3062 "Goodwill and Other Intangible Assets". The new
  standards mandate the purchase method of accounting for business
  combinations and require that goodwill no longer be amortized but instead
  be tested for impairment at least annually. The standards also specify
  criteria that intangible assets must meet to be recognized and reported
  apart from goodwill. The standards require that the value of the shares
  issued in a business combination be measured using the average share price
  for a reasonable period before and after the date the terms of the
  acquisition are agreed to and announced. Previously, the consummation date
  was used to value the shares issued in a business combination.

  The Company has fully adopted these new standards as of September 1, 2002,
  and has discontinued amortization of all existing goodwill. The Company has
  also reviewed existing intangible assets, including estimates of remaining
  lives, and has reclassified $2.3 million from workforce to goodwill as of
  September 1, 2002 to conform with the new criteria.


                                                                       15 of 22

1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

  (b) CICA Handbook Section 1581, Business Combinations, and Section 3062,
      Goodwill and Other Intangible Assets (continued):

  In connection with Section 3062's transitional goodwill impairment
  evaluation, the Company is required to assess whether goodwill is impaired
  as of September 1, 2002. The Company has up to six months to determine the
  fair value of its reporting units and compare that to the units' carrying
  amounts. To the extent a reporting unit's carrying amount exceeds its fair
  value, the Company must perform a second step to measure the amount of
  impairment in a manner similar to a purchase price allocation. This second
  step is to be completed no later than August 31, 2003. Any transitional
  impairment will be recognized as an effect of a change in accounting
  principle and will be charged to opening retained earnings as of September
  1, 2002.

  Effective September 1, 2002, the Company had unamortized goodwill of $190.1
  million which is no longer being amortized. This change in accounting
  policy is not applied retroactively and the amounts presented for prior
  periods have not been restated for this change. The impact of this change
  is as follows:

3. LONG-TERM DEBT (CONTINUED)

  (ii) Mortgage payable :

    On September 10, 2002, the joint venture, Commerce Valley Realty Holding
    Inc. ("CVRH"), in which the Company has a 50 per cent ownership interest
    entered into a mortgage agreement with a lender to finance the building
    facility in Markham, Ontario. The Company's proportionate share of the
    mortgage amounted to $10.8 million (Cdn. $16.9 million), and the
    mortgage has a repayment term of 12 years bearing interest at a rate of
    6.96 per cent per annum. The underlying mortgage is denominated in
    Canadian dollars. Funding under the mortgage was received in October
    2002.

4. GUARANTEE

The Company and other owners of CVRH have jointly and severally provided a
guarantee for the mortgage payment of the building facility in Markham,
Ontario. 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 for it under this guarantee. The monthly mortgage
interest and principal payment amounts to approximately $0.2 million. The
mortgage has a repayment term of 12 years with a maturity date on November 1,
2014. As of November 30, 2002, the outstanding amount of the mortgage stood at
$21.6 million.

In addition, the Company posted a letter of credit in the amount of $1.9
million in favour of CVRH and CVRH, in turn, assigned this letter of credit
for 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.

5. LOSS ON INTEREST RATE SWAP

In fiscal 2001, CVRH entered into an interest rate swap contract to hedge its
exposure to the interest rate risk applicable to its mortgage for the building
facility in Markham, Ontario. This interest rate swap contract closed on
September 10, 2002 resulting in a proportionate loss of $1.4 million to the
Company. The loss is treated as a deferred expense item in the balance sheet
and is charged to the consolidated statements of operations and retained
earnings as a yield adjustment to the interest expense, over the term of the
mortgage.


                                                                        18 of 22

9. STOCK-BASED COMPENSATION

For stock options granted to employees, had the Company determined
compensation costs based on the "fair value" of the stock options at grant
dates consistent with the method prescribed under CICA Handbook Section 3870,
the Company's net income per share would have been reported as the pro forma
amounts indicated below:


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

                                                       Three months
                                                          ended
   (Thousands of US dollars, except per share          November 30,
   amounts)                                                2002
  -----------------------------------------------------------------
                                                    
   Net income for the period, as reported                 $4,988
   Pro forma adjustment for stock-based compensation         (18)
  -----------------------------------------------------------------
   Pro forma net income                                   $4,970
  -----------------------------------------------------------------
   Pro forma net income per share - basic and diluted     $ 0.02
  -----------------------------------------------------------------


The weighted average estimated fair value at the date of grant for the options
granted for the three months ended November 30, 2002 was $3.55 per share. The
"fair value" of each option granted was estimated on the date of the grant
using the Black-Scholes option pricing model with the following assumptions:


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

                                                          Three months

   Risk-free interest rate                                      3.81%
   Dividend yield                                                  0%
   Volatility factor of the expected market price of the
    Company's common shares                                    69.75%
   Weighted average expected life of the options           4.13 years
  --------------------------------------------------------------------


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


                                                                       21 of 22
