LGA 775 CPU list: Core 2 Quad, Duo, Extreme and Xeon

LGA 775 (Socket T) carried Intel desktop chips from the Pentium 4 years to the last Core 2 Quads, plus the Xeon 3000 and 3300 series for single-socket servers. These pages cover the Core 2 era chips that matter for upgrades and for comparing Xeons with their desktop twins.

35 chips, fastest first. Each row opens the full spec sheet.
