Kentsfield (microprocessor)

Kentsfield was the codename for Intel's first desktop quad-core processor, released in November 2006. It was based on a multi-chip module (MCM) design, essentially combining two Conroe-based dual-core dies (Core 2 Duo) onto a single processor package. This approach allowed Intel to quickly release a quad-core processor using existing and well-established manufacturing processes, rather than waiting for a monolithic quad-core design.

The Kentsfield processors utilized the LGA 775 socket and were compatible with chipsets that supported the Core 2 Duo processors. However, due to the higher power consumption of having two dies, certain motherboard BIOS updates were required to ensure proper operation.

Kentsfield processors were marketed under the Intel Core 2 Quad brand, with specific models identified by a Q followed by a numerical designation (e.g., Q6600, Q6700). Performance improvements over dual-core processors were noticeable in multi-threaded applications and workloads that could effectively utilize all four cores. However, single-threaded performance was generally comparable to the underlying Conroe-based Core 2 Duo processors from which they were derived.

The Kentsfield architecture represented a significant step in the transition towards multi-core computing for desktop systems, paving the way for later monolithic quad-core and more advanced multi-core designs. Its release demonstrated Intel's strategy of utilizing existing technology to quickly respond to market demands while developing more advanced and integrated solutions.
