2 Quad Processor Q9400  

for Embedded Computing

Product Overview

Ideal for graphics and multimedia processing, this is the first quad-
core processor within the Intel® Core™2 processor product line with 
embedded lifecycle support. Based on Intel® Core™ microarchi-
tecture, the Intel® Core™2 Quad processor Q9400

Δ

 features four 

complete execution cores within a single processor, delivering  
exceptional performance and responsiveness in multi-threaded 
and multi-tasking environments. As a result, more instructions  
can be carried out per clock cycle, shorter and wider pipelines  
execute commands more quickly, and improved bus lanes move 
data throughout the system faster. 

Built on Intel’s hafnium-based 45nm Hi-k metal gate silicon  
technology, the processor delivers greater performance with  
less energy, doubling the transistor density, increasing cache  
size by up to 50 percent, and improving efficiency and speed  
relative to previous-generation 65nm processors.  

The processor is validated with four different chipsets, providing  
a choice of flexible, quad-core-capable platforms for a wide range 
of embedded applications:

• 

Intel® G45 Express chipset:

 Includes the next-generation  

Intel® Graphics Media Accelerator X4500HD (Intel® GMA 
X4500HD), with built-in support for full 1080p high definition  
video playback, including Blu-ray* content. This powerful video 
engine delivers smooth HD playback without the need for 
add-in video cards or decoders. Intel® Clear Video Technology, 
a combination of video processing hardware and software 
technologies, provides crystal-clear images without the imper-
fections and artifacts typically associated with video content. 
It allows embedded computing applications to connect to a 
wide range of digital display interfaces, including High-Definition 
Multimedia Interface* (HDMI*) and DisplayPort.* HDMI supports 
all HD formats including 720p, 1080i, and 1080p. The chipset 
consists of the Intel® 82G45 Graphics and Memory Controller 
Hub (GMCH) and Intel® I/O Controller Hub (ICH) 10.

• 

Intel® Q45 Express chipset:

 Intel® Graphics Media Accelerator 

(GMA) 4500 provides robust graphics and media capabilities for 
applications such as gaming and retail (i.e., kiosks and digital  

signage), while Intel® Trusted Execution Technology

1

 (Intel® 

TXT) provides security functionality for embedded segments 
such as digital security surveillance. Intel® Active Management 
Technology

2

 (Intel® AMT) version 5.0 provides improved man-

ageability for applications such as point-of-service terminals 
or digital signs in a networked retail environment. Chipset 
consists of the Intel® 82Q45 GMCH and Intel® ICH10 DO.

 Intel® Q35 Express chipset:

 InteI® GMA 3100, Intel TXT and 

Intel AMT version 3.0 support embedded applications needing 
graphics, manageability, data protection and security such as 
point-of-service terminals and interactive PCs, industrial control 
and automation, gaming, print imaging and network security 
appliances. Chipset consists of the Intel® 82Q35 GMCH and the 
Intel® ICH9 DO.

• 

Intel® 3210 chipset:

 Server-class chipset includes Error 

Correcting Code memory for embedded applications needing 
high reliability, such as robotics on a factory floor, multi-function  
printers and network security applications. It provides robust 
I/O performance and memory speed for fast system respon-
siveness needed in mid-range network security appliances, 
print imaging, storage and I/O-intensive industrial applications. 
Chipset consists of the Intel® 3210 MCH and the Intel® ICH9R.
