second quarter of fiscal 2005, compared with a net income under GAAP of $9.4
million, or $0.03 per share (diluted), for the second quarter of fiscal 2004.

Net revenue for the six months ended July 31, 2004 was $566.7 million, an
increase of 57% over net revenue of $361.1 million for the six months ended
August 2, 2003. Net income under GAAP was $43.1 million, or $0.15 per share

under GAAP of $13.8 million, or $0.05 per share (diluted), for the six months
ended August 2, 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, and
amortization of stock-based compensation. Pro forma net income was $59.7
million, or $0.20 per share (diluted), for the second quarter of fiscal 2005,
compared with pro forma net income of $30.0 million, or $0.11 per share
(diluted), for the second quarter of fiscal 2004. Shares used in computing pro
forma net income per share for the second quarter of fiscal 2005 increased to
295.8 million, compared with 273.6 million for the second quarter of fiscal
2004.

Pro forma net income was $108.8 million, or $0.37 per share (diluted), for the
six months ended July 31, 2004, compared with pro forma net income of $54.5
million, or $0.20 per share (diluted), for the six months ended August 2, 2003.
Shares used in computing pro forma net income per share for the six months ended
July 31, 2004 increased to 294.0 million, compared with 266.4 million for the
six months ended August 2, 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.



"Q2 was a very successful quarter for Marvell. Along with another strong quarter
of revenue growth, we also continued to expand our operating margins and further
strengthen our balance sheet," stated Dr. Sehat Sutardja, Marvell's President
and CEO. "We are enjoying strong momentum in both the enterprise and consumer
markets. In particular, we are very excited about the rate of adoption of our
wireless LAN and storage electronics for emerging consumer applications as well
as continued strong design activity for our Linear DSP power management
products."

Revenue for the second quarter was a record for Marvell and represented the 27th
consecutive quarter of sequential revenue growth. Also, the 10% sequential
increase in the second quarter revenue was Marvell's 11th consecutive quarter
where sequential revenue growth was at least 10%. The following is a review of
some of the recent highlights that occurred since last quarter's earnings
release:

o Marvell continues to lead the adoption of WLAN into consumer electronic
devices. During the quarter, Marvell expanded upon its impressive list of
design wins into high volume applications such as cellular handsets, gaming
devices, digital cameras, MP3 players, PDAs and emerging home entertainment
multimedia client devices. Marvell expects to commence volume shipment into
such emerging applications in the third quarter including initial shipments
of its 802.11 solution into a major consumer gaming application. Also, a
number of Marvell's WLAN design wins for cellular handsets have now
commenced the field trial stage this summer.

o Today, Marvell raised the technological bar once again with the
introduction of the World's first 60 Gigabit per second single chip
solution. These new Prestera(TM) devices, which utilize the Marvell
distributed switching architecture, offer true security, advanced QOS and
full integrated support for next generation IPv6 protocols. The complete
Prestera product family continues to enjoy strong revenue growth and design
wins for infrastructure switching applications across all market segments
from the SMB to large scale Enterprise.

o Q2 was another outstanding quarter for Marvell's storage electronics for
the hard disk drive market. During the quarter, Marvell enjoyed continued
solid revenue growth from market share gains in the traditional hard disk
drive market. Additionally, the emerging consumer small form factor drive
market continues to grow as these exciting drives are designed into a
variety of consumer electronic devices. Marvell expects further strong
market adoption of consumer hard disk drives as even smaller form factor
drives and increased storage capacities begin to be introduced into the
marketplace.

o During the quarter, Marvell also commenced volume shipments of its
All-into-1 and LiveAP(TM)WLAN solutions that were just introduced earlier
this year. Marvell's All-into-1 technology for the first time allows the
integration of many WLAN functions into a single device that were
previously separate functions handled by multiple devices. Now, in just a
size of a credit card, one can add wireless capability to Ethernet enabled
devices, extend the range of any 802.11 g/b Access Point or wireless
router, provide easier setup for broadband wireless gaming over the
Internet, allow personal 54Mbps `hot-spot' connectivity and much more.
Marvell is also now shipping LiveAP(TM)into volume PC desktop motherboards
as an embedded access point product. LiveAP utilizes Marvell's extreme low
power and integrated processor technology to offer "on-demand" access to
the wireless network and Internet even when the host device is turned off.
