E6400

The Intel Core 2 Duo E6400 is a desktop processor that belongs to Intel’s Core 2 family, code-named Conroe. It was released in the mid-2000s as a mainstream dual-core option and is built on a 65-nanometer process. The E6400 targets everyday computing tasks with a balance of performance and power efficiency for its time.

Key specifications include a clock speed of 2.13 GHz, a 2 MB L2 cache, and a front-side bus of 1066 MHz. It uses the LGA 775 socket and has a thermal design power around 65 watts. The chip supports 64-bit computing and standard Core 2 features of the era, with the memory controller logic provided by the motherboard, typically paired with DDR2 memory.

In terms of positioning, the E6400 sits within the mid-range of the E6000 series and is adjacent to the faster E6600 and the slower E6300. It was commonly chosen for mainline desktops where a reliable, dual-core capable of multitasking and light multitasking workloads was desirable. The processor benefited from the then-new Conroe architecture’s efficiency and performance per watt relative to older Pentium 4 designs.

Over time, the E6400 was superseded by newer generations built on smaller processes (such as 45 nm and beyond) and updated architectures, but it remains representative of the era’s mainstream desktop platforms. The processor was used with a variety of motherboards supporting LGA 775, enabling a broad range of configurations and upgrades for business and home users.
