What the Core i7-980 is

Intel Core i7-980 is a six core Gulftown desktop processor that Intel released in June 2011 for high end towers. It runs at 3.33 GHz base with turbo to 3.6 GHz and includes Hyper-Threading, so 6 cores give 12 threads. Cache is 12 MB Intel Smart Cache. Power is 130 W on a 32 nm process.

Six cores brought workstation threading to desktop X58 boards at a lower price than the Extreme parts. Editing and rendering run well on 12 threads. The locked multiplier keeps clocks at rated values.

There is no integrated graphics on this die, so a separate card is always required. Memory runs in three DDR3 channels, which suits large projects with six DIMM slots.

Socket and motherboard compatibility

The Core i7-980 fits LGA 1366 in FCLGA1366 form. X58 boards boot Gulftown with current microcode, while early boards may need a BIOS update first. The socket uses a load plate with a lever.

QuickPath links the CPU to the X58 northbridge at 4.8 GT/s on this SKU. A board that lists the exact 980 string is the safe choice for used builds.

Memory, PCIe and cooling

Memory support is DDR3-1066, three channels, up to 24 GB on desktop X58 boards with 6 DIMM slots. Three matched modules give the rated bandwidth. ECC is not supported on desktop boards.

PCI Express is revision 2.0 from the X58 chipset for graphics and fast storage, commonly as two x16 slots for multi GPU builds.

Cooling needs a 130 W rated tower on the 80 by 80 mm pattern. The stock cooler is loud under load, so a large aftermarket tower helps.

Upgrade paths

On LGA 1366 the 980 can move to the unlocked 980X or 990X for tuning on X58 boards. DDR3 and storage carry over. A same socket workstation reference is Intel Xeon W3690.

A platform move to LGA 2011 needs a new board and memory population in fours. Keep the X58 rig for editing after a GPU refresh.
