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® G45 Express chipset for embedded applications requiring enhanced media functionality such as retail and transaction solutions (point-of-service, ATMs, kiosks, digital signage, transaction terminals), gaming machines and medical appliances. Chipset consists of the Intel® 82G45 Graphics and Memory Controller Hub (GMCH) and Intel® I/O Controller Hub (ICH) 10.
- Intel® Q45 Express chipset for applications such as retail and transaction solutions (point-of-service, ATMs, kiosks, digital signage, transaction terminals) in a networked retail environment. Chipset consists of the Intel® 82Q45 Graphics and Memory Controller Hub (GMCH) and Intel® I/O Controller Hub 10 DO.
- Intel® Q35 Express chipset for embedded applications needing graphics, manageability, data protection and security such as retail and transaction solutions (point-of-service, ATMs, kiosks, digital signage, transaction terminals), 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
