Intel Core 2 Quad microprocessors are essentially two Core 2 Duo CPUs in one package – two cores are located on one die, two other cores are on another die, and both dies are packaged together. This explains why the level 2 cache on these processors is shared only between two cores. Obviously, these CPUs have higher (about 50% higher) Thermal Design Power than dual-core microprocessors running at the same frequency. The quad-core CPUs have the same performance as the Core 2 Duo processors in single-threaded applications, and are faster or considerably faster in multi-threaded applications. Performance difference in games between quad- and dual-core microprocessors is highly dependent on the game, and varies from no difference at all to 20% performance advantage for quad-core CPUs. The quad-core processors are packaged in socket 775 package, and work in the same motherboards as the Core 2 Duo CPUs. www.os-store.com
