Gulftown or Westmere-E is the codename of an up to six-core
hyperthreaded Intel processor able to run up to 12 threads in parallel. It is based on
Westmere microarchitecture, the
32 nm
The "32 nm" node is the step following the "45 nm" process in CMOS (MOSFET) semiconductor device fabrication. "32-nanometre" refers to the average half-pitch (i.e., half the distance between identical features) of a memory cell at this technolo ...

The first release was the Core i7 980X in the first quarter of 2010, along with its server counterpart, the Xeon 3600 and the dual-socket Xeon 5600 (Westmere-EP) series using identical chips.
Processor
First figures indicate that at equivalent clock rates, depending on the software, it has up to 50% higher performance than the identically clocked quad-core
Bloomfield Core i7-975. Despite having 50% more transistors, the CPU strongly benefits from the 32-nm process, drawing the same or even less power (depending on the operating system) than its Bloomfield predecessors with merely four cores. The
thermal design power (TDP) of all planned models is stated to be 130
watt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Work ...

Westmere-EP is the first six-core dual-socket processor from Intel, following the quad-core
Bloomfield and
Gainestown (also known as Nehalem-EP) processors using the same
LGA 1366 package, while the earlier
Dunnington six-core processor is a
Socket 604 based multi-socket processor. The
CPUID
In the x86 architecture, the CPUID instruction (identified by a CPUID opcode) is a processor supplementary instruction (its name derived from " CPU Identification") allowing software to discover details of the processor. It was introduced by Int ...
extended model number is 44 (2Ch) and two product codes are used, 80613 for the UP desktop/server models and 80614 for the Xeon 5600-series DP server models. In some models, only four of the six cores are enabled.
Since 2014, Xeon 3600 and 5600 series Westmere-EP processors became somewhat sought-after as an upgrade route for older X58 motherboards. In some cases, motherboard BIOS revisions have allowed the installation of these six core processors onto boards originally targeted for two or four core processors In fully threaded workloads, total system performance will increase by a value equal to the number of cores added (i.e. moving from a four core 2.6 GHz to a six core 2.6 GHz system would deliver 50% more multithreaded performance). With proper BIOS support and the correct supporting components, many users have reported substantial overclocking potential, often as high as 4.4 GHz while staying within Intel's maximum allowed voltages (no higher than 1.35v for the core or the uncore)
