                ATI Updates First-Quarter Financial Expectations

        Broad-based demand for PC products leads to improved expectations

MARKHAM, Ontario, Monday November 17, 2003 - 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 provided an update on its
expectations for its financial results for the first quarter of its fiscal 2004
ending November 30, 2003.

ATI now expects revenue to be in the range of $440(1) to $470 million. Adjusted
net earnings(2) are expected to be in the range of $0.16 to $0.20. ATI expects
to see continued strength in the second quarter, but a typical seasonal pattern,
resulting in a slightly weaker revenue and profit profile.

"Broad-based demand for ATI's PC products, particularly in the desktop business,
has contributed to the greater-than-expected sales this quarter," said David
Orton, President and Chief Operating Officer of ATI Technologies. "This demand,
coupled with a stable price environment, has also contributed to gross margins
that are expected to exceed original expectations."

1 All dollar amounts are stated in U.S. dollars unless otherwise noted. All per
share amounts are stated on a diluted basis unless otherwise noted.

2 Adjusted net income excludes the after-tax effect of gain on investments,
after-tax effect of other charges to the consolidated financial statements,
amortization of goodwill 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. Each of these
items has been excluded from adjusted net income as they are not considered to
be part of the Company's normalized 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.






                                                                     Page 4 of 6

Forward-looking Statements and Uncertainties

Certain statements in this release constitute "forward-looking statements." When
used in this release, words such as "plans," "intends," "anticipates," "should,"
"estimates," "expects," "believes," "indicates," "targeting," "suggests," and
similar expressions are intended to identify forward-looking statements.
Forward-looking statements are based on current expectations and entail various
risks and uncertainties that are outlined in this release and in the Company's
2002 Annual Report and 2002 Annual Information Form. As a result of these risks
and uncertainties, the Company's operating results and common share price may be
subject to significant volatility, particularly on a quarterly basis. For
example, the markets for the Company's products are characterized by changing
market conditions, frequent new product introductions, seasonal and variable
demand and rapid technology changes. Other factors that could cause the
Company's results to vary include, but are not limited to, lack of anticipated
growth in the demand for PCs, gaming consoles and consumer electronic devices in
which the Company's products are incorporated, reductions in the Company's
average selling prices for its products due to competitive pressures and other
factors, the introduction of new products by the Company's competitors which
render the Company's products non-competitive, delays encountered by the Company
in developing new products or enhancements, including integrated graphics and
core logic components, in the time frame required by its customers, delays in
manufacturing or unfavourable manufacturing yields experienced by the Company's
independent foundries, unexpected variances in material costs, including silicon
wafer, memory and printed circuit boards, and constraints on the supply of
components utilized in the Company's products and in the PC industry generally.
These risks and uncertainties could cause or contribute to actual results that
are materially different from those anticipated or experienced in the past.
Additional information concerning factors that could cause the Company's
financial results to fluctuate is contained in the Company's filings with
Canadian and U.S. securities regulatory authorities. ATI disclaims any
obligation or intention to update or revise any forward-looking statement,
whether as a result of new information, future events or otherwise.
