Trident XP4™ Enables New Price/Performance
Standard for DX8.1/9.0 Graphics Cards

High-end Graphics At Irresistible
Prices

Sunnyvale, CA, August 5, 2002:

Trident Microsystems, Inc. (NASDAQ:TRID),
is unveiling its desktop XP4™ 3D graphics family setting
a new price/performance standard for Microsoft’s DX8.1/9.0-compliant
graphics cards for less than $100, with 128MBytes of up to
700MHz DDR memory.

“This is just the beginning of what will be a relentless
drive to provide high-end graphics performance for mainstream
PC end-users,” said Le Nguyen, assistant vice president
of marketing for Trident. “Whereas the $300 high-end
graphics card segment represents less than three percent of
the total market, our focus is in the mainstream and value
segments where the volume is 25 times greater. The desktop
XP4 product family brings high-end 3D graphics experience
to all PC end-users with photo-finish image quality and movie-class
special effects at such affordable price points never before
made possible.”

“Our company actually started out in desktop PC graphics
15 years ago,” said Frank Lin, president and CEO of Trident.
“The XP4 will take us back to the future where only a
few other credible graphics chip suppliers can remain. We
intend to hasten the pace of competition with even higher
performance products and solidify our leadership in price/performance.”

XP4 Desktop Product Family

The XP4 desktop product family is available in three versions:

- XP4 T3 supporting 128MBytes of up to 700MHz DDR memory with
128-bit bus;

- XP4 T2 supporting 64Mbytes of 500MHz DDR memory with 128-bit
bus;

- XP4 T1 supporting 64Mbytes of 500MHz DDR memory with 64-bit
bus.

The XP4 T3 tops the performance chart with a 300MHz graphics
engine and enables PC OEMs plus card makers to deliver advanced
DX8.1/9.0 graphics card with 128MBytes memory for less than
$99 (suggested retail price) to the end-users. The 128-bit
Double-Data-Rate (DDR) memory system reaches a bandwidth of
up to 11.2 Gbytes/sec and the 3D graphics engine achieves
a peak performance of 1.2 billion pixels/sec.

The XP4 T3 offers a maximum power dissipation of less than
four watts. This corresponds to only a fraction of competing
alternatives, improving chip reliability in typical consumer-oriented
operating environments where overheating could be the cause
of system failure.

The XP4 T2 provides mainstream DX8.1/9.0 performance with
a 250MHz graphics engine and reduces the end-user price of
64Mbytes graphics card to less than $79 (suggested retail
price). XP4 T2 memory bandwidth peaks at 8.0 Gbytes/sec and
3D graphics performance hits 1 billion pixels/sec, rivaling
other high-end, competitive products.

The XP4 T1 brings entry-level DX8.1/9.0 graphics card to
a rock-bottom price of less than $69 (suggested retail price)
also with a 250MHz graphics engine but in a 64-bit memory
bus for lowest cost. The XP4 T1 memory bandwidth reaches 4.0
Gbytes/sec.

XP4 Core Technology Summary

The XP4 desktop family is based on UMC’s 0.13um CMOS technology
that uses only 30 million transistors, which is less than
half the number of transistors of the nearest competitive
equivalent, to deliver top-of-the-line DX8.1/9.0 features
and performance.

Other key capabilities of the XP4 family include:

- BrightPixel™ rendering engine with hardware
vertex and pixel shaders

- SmartTile™ memory architecture for optimal
memory bandwidth utilization

- CoolPower™ for low power management

- Multiview with CRT, DVI and TVout

- Resolution up to QXGA (2048×1536) with 420MHz RAMDAC

- DXVA hardware support with both IDCT and Motion Compensation

- Advanced de-interlacing for highest-quality DVD movies

- AGP-4X bus interface

Price and availability

XP4 T1, T2 and T3 are sampling now. Pricing, in quantity,
is $30.95, $34.95 and $39.95. Packaging for all three versions
of the XP4 is in 612-pin BGA (31mmx31mm)
