The 3100 series, codenamed '''Wolfdale''' (product code 80570) dual-core Xeon (branded) CPU, was just a rebranded version of the Intel's mainstream [[Intel Core 2|Core 2 Duo]] E7000/E8000 and [[Pentium Dual-Core]] E5000 processors, featuring the same [[45 nanometer|45&nbsp;nm process]] and 6&nbsp;MB of L2 cache. Unlike most Xeon processors, they only support single-CPU operation. They use [[LGA 775]] (Socket T), operate on a 1333&nbsp;MT/s front-side bus, support Enhanced Intel [[SpeedStep]] Technology and Intel Virtualization Technology but do not support Hyper-Threading.

On June 26, 2006, Intel released the dual-core CPU (Xeon branded 5100 series) codenamed '''Woodcrest''' (product code 80556); it was the first Intel [[Intel Core (microarchitecture)|Core/Merom microarchitecture]] processor to be launched on the market. It is a dual-processor server and workstation version of the [[Intel Core 2|Core 2]] processor. Intel claimed that it provides an 80% boost in performance, while reducing power consumption by 20% relative to the 5000 series ''Dempsey''.

Most models have a 1333{{nbsp}}MT/s FSB, except for the 5110 and 5120, which have a 1066{{nbsp}}MT/s FSB. The fastest processor (5160) operates at 3.0{{nbsp}}GHz. All Woodcrest processors use the [[LGA 771]] (Socket J) socket and all except two models have a TDP of 65{{nbsp}}W. The 5160 has a TDP of 80{{nbsp}}W and the 5148LV (2.33{{nbsp}}GHz) has a TDP of 40{{nbsp}}W. The previous generation Xeons had a TDP of 130{{nbsp}}W. All models support Intel 64 (Intel's x86-64 implementation), the [[NX bit|XD bit]], and [[x86 virtualization|Virtualization Technology]], with the [[Demand-based switching]] power management option only on Dual-Core Xeon 5140 or above. Woodcrest has 4&nbsp;MB of shared L2 cache.

Intel released relabeled versions of its quad-core [[List of Intel Core 2 microprocessors#.22Yorkfield.22 .2845 nm.29|Core 2 Quad Yorkfield]] Q9300, Q9400, Q9x50 and QX9770 processors as the Xeon 3300-series (product code 80569). This processor comprises two separate dual-core dies next to each other in one CPU package and manufactured in a [[45 nanometer|45&nbsp;nm process]]. The models are the X3320, X3330, X3350, X3360, X3370 and X3380, being rebadged Q9300, Q9400, Q9450, Q9550, Q9650, QX9770, running at 2.50&nbsp;GHz, 2.66&nbsp;GHz, 2.66&nbsp;GHz, 2.83&nbsp;GHz, 3.0&nbsp;GHz, and 3.16&nbsp;GHz, respectively. The L2 cache is a unified 6&nbsp;MB per die (except for the X3320 and X3330 with a smaller 3&nbsp;MB L2 cache per die), and a front-side bus of 1333&nbsp;MHz. All models feature Intel 64 (Intel's x86-64 implementation), the [[NX bit|XD bit]], and [[x86 virtualization|Virtualization Technology]], as well as [[Demand-based switching]].

The [[Yorkfield (microprocessor)#Yorkfield CL|Yorkfield-CL]] (product code 80584) variant of these processors are X3323, X3353 and X3363. They have a reduced TDP of 80W and are made for single-CPU [[LGA 771]] systems instead of [[LGA 775]], which is used in all other Yorkfield processors. In all other respects, they are identical to their Yorkfield counterparts.

A quad-core (2×2) successor of the Woodcrest for DP segment, consisting of two dual-core Woodcrest chips in one package similarly to the dual-core Pentium D branded CPUs (two single-core chips) or the quad-core [[Kentsfield (microprocessor)|Kentsfield]]. All Clovertowns use the [[LGA 771]] package. The Clovertown has been usually implemented with two Woodcrest dies on a [[Multi-Chip Module|multi-chip module]], with 8&nbsp;MB of L2 cache (4&nbsp;MB per die). Like Woodcrest, lower models use a 1066&nbsp;MT/s FSB, and higher models use a 1333&nbsp;MT/s FSB.

On November 11, 2007 Intel presented [[Yorkfield]]-based Xeons – called Harpertown (product code 80574) – to the public.<ref>{{cite web|url=https://www.intel.com/Assets/PDF/datasheet/318589.pdf|title=Quad-Core Intel Xeon Processor 5400 Series|date=August 2008|website=Intel}}</ref> This family consists of dual die quad-core CPUs manufactured on a [[45 nanometer|45&nbsp;nm process]] and featuring 1066&nbsp;MHz, 1333&nbsp;MHz, 1600&nbsp;MHz front-side buses, with TDP rated from 40&nbsp;W to 150&nbsp;W depending on the model. These processors fit in the [[LGA 771]] package. All models feature Intel 64 (Intel's x86-64 implementation), the [[NX bit|XD bit]], and [[x86 virtualization|Virtualization Technology]]. All except the E5405 and L5408 also feature [[Demand-based switching]]. The supplementary character in front of the model-number represents the thermal rating: an L depicts a TDP of 40&nbsp;W or 50&nbsp;W, an E depicts 80&nbsp;W whereas an X is 120&nbsp;W TDP or above. The speed of 3.00&nbsp;GHz comes as four models, two models with 80&nbsp;W TDP two other models with 120&nbsp;W TDP with 1333&nbsp;MHz or 1600&nbsp;MHz front-side bus respectively. The fastest Harpertown is the X5492 whose TDP of 150&nbsp;W is higher than those of the Prescott-based Xeon DP but having twice as many cores. (The X5482 is also sold under the name "Core 2 Extreme QX9775" for use in the [[Intel Skulltrail]] system.)

Intel 1.6&nbsp;GT/s front-side bus Xeon processors will drop into the Intel 5400 (Seaburg) chipset whereas several mainboards featuring the Intel 5000/5200-chipset are enabled to run the processors with a 1333&nbsp;MHz front-side bus speed. Seaburg features support for dual {{nowrap|PCIe 2.0 x16}} slots and up to 128&nbsp;GB of memory.<ref>{{cite web |url=http://www.dailytech.com/Intel+Readies+1600+MHz+FrontSide+Bus+Xeons/article8656.htm |title=Intel Readies 1600&nbsp;MHz Front-Side Bus Xeons |website=[[DailyTech]] |archive-url=https://web.archive.org/web/20160401180832/http://www.dailytech.com/Intel+Readies+1600+MHz+FrontSide+Bus+Xeons/article8656.htm |archive-date=April 1, 2016 |url-status=dead}}</ref><ref>{{cite web |url=http://www.trustedreviews.com/cpu-memory/news/2007/08/30/Intel-Xeons-Coming-With-1600MHz-FSB/p1 |title=Intel Xeons Coming With 1600MHz FSB |website=[[TrustedReviews]]}}</ref>

The 7300 series, codenamed '''Tigerton QC''' (product code 80565) is a four-socket (packaged in [[Socket 604]]) and more capable [[quad-core processor]], consisting of two [[dual core]] Core 2 architecture silicon chips on a single ceramic module, similar to Intel's Xeon 5300 series Clovertown processor modules.<ref>{{cite press release |title=Intel Launches First Industry-Standard Quad-Core Products for High-End, Multi-Processor Servers |url=https://www.intel.com/pressroom/archive/releases/2007/20070905comp.htm |location=Santa Clara, CA |website=Intel |language=en-US |date=September 5, 2007 |access-date=November 13, 2022}}</ref>

The 7300 series uses Intel's Caneland (Clarksboro) platform.

Intel claims the 7300 series Xeons offer more than twice the performance per watt as Intel's previous generation 7100 series. The 7300 series' Caneland chipset provides a point to point interface allowing the full front side bus bandwidth per processor.

The 7xxx series is aimed at the large server market, supporting configurations of up to 32&nbsp;CPUs per host.

It features a 1.07&nbsp;GT/s [[Front Side Bus|FSB]], fits into the Tigerton's mPGA604 socket, and is compatible with both the Intel Caneland and IBM X4 chipsets. These processors support DDR2-1066 (533&nbsp;MHz), and have a maximum [[Thermal Design Power|TDP]] below 130&nbsp;W. They are intended for blades and other stacked computer systems. Availability was scheduled for the second half of 2008. It was followed shortly by the [[Nehalem (microarchitecture)|Nehalem microarchitecture]]. Total transistor count is 1.9 billion.<ref>{{cite web |last=Prickett Morgan |first=Timothy |date=September 15, 200|title=Chipzilla unveils six-core 'Dunnington' Xeons |url=https://www.theregister.com/2008/09/15/intel_dunnington_xeon/ |website=The Register |language=en-US |access-date=December 10, 2022}}</ref>
