Intel Xeon processors (Core 2 era)

Xeons from the Core 2 years: dual-socket 5100, 5300, 5400 and 5200 series on LGA 771, single-socket X3x23/X3x53/X3x63 on LGA 771, and the 3000 and 3300 series on LGA 775. Low-voltage L and LV parts trade clock speed for a lower TDP.

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