Intel® Core™2 Quad Processor Q9400

The Intel® Core™2 Quad processor Q9400¹ is the first quad-core processor within the Intel® Core™2 processor product line with embedded lifecycle support. Based on Intel® Core™ microarchitecture, it 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.
The processor is validated with three different chipsets, providing a choice of flexible, quad-core-capable platforms for a wide range of embedded applications:
Intel® Q45 Express chipset for applications such as point-of-sale (POS) terminals or digital signs in a networked retail environment. Chipset consists of the Intel® 82Q45 Graphics and Memory Controller Hub (GMCH) and Intel® I/O Controller Hub (ICH) 10 DO.
Intel® Q35 Express chipset for embedded applications needing graphics, manageability, data protection and security such as interactive clients (i.e. POS 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 is a server-class chipset that 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.
Product highlights
Multi-processing capabilities of the four complete execution cores deliver sharper images, provide faster response rates and support additional multi-media features - ideal for gaming arcade consoles, POS terminals and digital signage.
In multi-tasking environments, where rendering and manageability as well as media and software applications can be distributed to run in parallel across each of the four cores, greater visualization and realism can be attained.
The processor includes a Super Shuffle Engine to increase the speed of existing Intel® Streaming SIMD Extensions (SSE) algorithms optimized for graphics and multi-media processing. The engine significantly improves performance for the latest Intel® SSE4 instructions which enhance video editing and encoding used in many embedded applications.
Intel® Wide Dynamic Execution enables delivery of more instructions per clock cycle to improve execution time and energy efficiency
Intel® Intelligent Power Capability of the processor is designed to deliver more energy-efficient performance
Larger Intel® Advanced Smart Cache in the processor is optimized for multi-core processors, providing a higher-performance, more efficient cache subsystem
Dual Intel® Dynamic Acceleration Technology improves four-core performance by utilizing power headroom of idle cores by dynamically boosting frequency of active cores
