BX80580Q8400 | Intel Core 2 Quad Q8400 (2.66GHz) - LGA775, 1333FSB, 4MB

The Intel Core2 Quad processor is the world's first quad-core desktop processor, delivering the latest in cutting-edge processor technology and unprecedented performance across a wide range of applications and benchmarks. The new Intel Core 2 Quad processors QX9xxx series are based on the industry-leading 45nm manufacturing technology, providing another giant leap forward on the road to multi-core and parallel computing.

The unprecedented performance of the Intel Core 2 Quad processor is made possible by each of the four complete execution cores delivering the full power of Intel Core microarchitecture. 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. This quad-core processor represents Intel's continued leadership and drive of multi-core processing and more parallel computing.

The latest versions built on Intel's 45nm manufacturing technology take these benefits to a whole new level. This new technology uses hafnium-infused Hi-k transistors, enabling even more processor performance by doubling the transistor density, improving efficiency and speed relative to the previous generation, and increasing cache size by up to 50 percent. These new Intel Core 2 Quad processors deliver even more performance without using more energy.
