for the third quarter of fiscal 2005, compared with a net income under GAAP of
$12.0 million, or $0.04 per share (diluted), for the third quarter of fiscal
2004.

Net revenue for the nine months ended October 30, 2004 was $884.3 million, an

income under GAAP of $25.7 million, or $0.09 per share (diluted), for the nine
months ended November 1, 2003.

Marvell reports net income and basic and diluted net income per share in
accordance with GAAP and additionally on a non-GAAP basis, referred to as pro
forma. Pro forma net income, where applicable, excludes the effect of
amortization and write-off of acquired intangible assets and other, amortization
of stock-based compensation and charges related to facilities consolidation. Pro
forma net income was $66.6 million, or $0.22 per share (diluted), for the third
quarter of fiscal 2005, compared with pro forma net income of $35.1 million, or
$0.12 per share (diluted), for the third quarter of fiscal 2004. Shares used in
computing net income per share for the third quarter of fiscal 2005 increased to
301.0 million, compared with 284.8 million for the third quarter of fiscal 2004.

Pro forma net income was $175.4 million, or $0.59 per share (diluted), for the
nine months ended October 30, 2004, compared with pro forma net income of $89.6
million, or $0.33 per share (diluted), for the nine months ended November 1,
2003. Shares used in computing pro forma net income per share for the nine
months ended October 30, 2004 increased to 296.3 million, compared with 272.5
million for the nine months ended November 1, 2003.

These non-GAAP measures should be considered in addition to, and not as a
substitute for, the results prepared in accordance with GAAP. A reconciliation
of GAAP net income to pro forma net income is included in the financial
statements portion of this release as well as on our website in the Investors
section at www.marvell.com.

Marvell's management believes the non-GAAP information is useful because it can
enhance the understanding of the Company's ongoing economic performance and
Marvell therefore uses pro forma reporting internally to evaluate and manage the
Company's operations. Marvell has chosen to provide this information to
investors to enable them to perform comparisons of operating results in a manner
similar to how the Company analyzes its operating results.





"Q3 was another solid quarter for Marvell with record revenues, continued
operating margin expansion, and solid cash flows," stated Dr. Sehat Sutardja,
Marvell's President and CEO. "We continue to demonstrate our sharp focus and
ability to execute our business strategies even in challenging economic and end
market conditions. We of course are very proud of our strong financial track
record which is a reflection of the strength of our technology, the strong
partnerships we have built with our customers and suppliers, and the dedication
and hard work of our employees."

Revenue for the third quarter was a record for Marvell and represented the 28th
consecutive quarter for sequential revenue growth. During the quarter Marvell
also reported its highest level of cash, cash equivalents and short-term
investments with a balance of $577.3 million. The following is a review of some
of the recent highlights that occurred since last quarter's earnings release:

o During the quarter, Marvell announced it is driving the CE-ATA
initiative with key industry players including Hitachi Global Storage
Technologies, Intel Corporation, Seagate Technology and Toshiba America
Information Systems. Marvell initiated the definition of this standard
storage interface for small form factor disk drives that addresses the
requirements of the handheld and consumer electronics (CE) market
segments, including low pin count, low voltage, power efficiency, cost
effectiveness and integration efficiency. Additionally, Marvell also
announced, as a result of a dedicated four-year development effort, the
industry's only System on Chip (SOC) device supporting the new CE-ATA
specification. The Marvell 88i6310 SOC along with its accompanying
reference firmware is the first device designed specifically to enable
next generation small form factor disk drives.

o Marvell announced the further expansion of its Prestera(R) packet
processors with the industry's most comprehensive support for IPv6 which
allows customers to quickly incorporate IPv6 features into their product
portfolios ranging from SOHO to Enterprise products at every performance
point including Fast-, Gigabit-, and 10 Gigabit- Ethernet. IPv6 is an
evolutionary standard that enables customers to manage the growing
number of networked consumer electronic devices without running into the
addressing scheme limitations inherent to IPv4. Unique to the Prestera
devices is comprehensive IP-in-IP tunneling support that enables
coexistence with current networks as well as the migration from IPv4 to
the next generation IPv6 networks.

o Marvell continues to expand upon its diverse list of high volume
wireless LAN design wins for exciting consumer applications such as
cellular handsets, gaming devices, digital cameras, printers, MP3
players, PDAs, and emerging home entertainment multimedia client
devices. Marvell also announced a new family of innovative 802.11a/g
wireless devices designed to allow end users fast, simple and
easy-to-use wireless networks. The new patent pending features include
"AutoLink" technology, for one-click user configuration, "BoostMode" for
doubling 54Mbps range and performance, and "FLEXMode" for simplified,
concurrent a/g operation.
