Intel® 440BX AGPset Product Overview The Intel® 440BX AGPset is the first chipset to optimize Intel® Pentium® III processor performance for 3D and video applications with 100-MHz system bus/SDRAM. As Intel's second-generation AGPset with Intel® Quad Port Acceleration (QPA), the Intel 440BX AGPset improves the speed of the system bus from 66 MHz to 100 MHz, while increasing the width and depth of buffers to the system bus, Accelerated Graphics Port, SDRAM, and the PCI bus. In addition, the 440BX AGPset can interface with ATA/66 HDD in UDMA mode 2. This makes the Intel 440BX AGPset an excellent design solution for “next-generation performance“ in consumer desktop, corporate small business desktop, mobile, workstation and server market systems. By optimizing the performance of the Intel® Pentium® III processor with Dual Independent Bus (DIB) architecture, the new Intel 440BX AGPset supports the emerging set of visual computing applications, including 3D and video applications for design, data visualization, Web content creation, education, and gaming.
Ease of Design & Scalability
Designing with the Intel 440BX AGPset is simplified because the chipset enables scalable motherboard designs with either a 66-MHz or 100-MHz system bus. To further improve design investments, the Intel 440BX AGPset is form-factor compliant with the current Intel® 440LX AGPset. Design collateral is a superset of Intel 440LX AGPset design collateral, focusing on 100-MHz SDRAM and enhanced power and thermal management.
Ideal for Mobile Systems
The Intel 440BX AGPset is the first chipset for mobile Intel® Pentium® III processor-based systems, with an architecture optimized to deliver the highest performance in mobile systems. Specifically, the Intel 440BX AGPset Features enhanced power management, including ACPI support, which makes it an ideal choice for low-power mobile platforms. With its flexible feature set, the Intel 440BX AGPset is the solution for mobile Intel® Pentium® III processor-based systems and mobile Intel® Pentium® II processor-based systems, today and tomorrow.
Optimizing Intel® Pentium® III Processor Performance
The Intel 440BX AGPset optimizes the performance of the Intel® Pentium® III processor in desktop systems by implementing Intel Quad Port Acceleration (QPA). This capability improves system performance through four-port concurrent arbitration of the processor bus, graphics bus, PCI bus, and SDRAM. Intel® QPA allows the Intel 440BX AGPset and the Intel® Pentium® III processor to deliver optimal performance in visual computing applications, including 3D graphics.
