The Intel Core 2 Duo E7400 is a 2.8 GHz, 1066MHz FSB processor with 3MB Cache and falls in the lower quarter of Intel's line of Core 2 Duo Processors. All processors in this line have 2 cores (hence the name) meaning they have two distinct processors on one chip allowing them to work seperately or together on a single large task. These processors also feature next generation Intel Core microarchitecture for better overall performance and Intel HD Boost which delivers up to 70% higher performance when encoding high-definition information from your HD video camera while Intel Clear Video Technology gives smoother video playback. Intel Intelligent Power Capability allows the processor to run with increased performance without increasing power consumption resulting in energy-efficient perfomance. The Intel Core 2 Duo processors also feature Intel Graphics Technology allowing users to fully capitalize on visual advancements offered by Windows Vista Home Premium edition.
