The Intel Core i7-980 is a high-end desktop processor launched in June 2011, based on the 32nm Gulftown architecture. It represents a higher-clocked, non-Extreme Edition 6-core processor, operating at a base frequency of 3.333 GHz and boosting up to 3.6 GHz via Turbo Boost. It features 6 cores and 12 threads, supported by a massive 12 MB L3 cache. Utilizing the LGA 1366 socket, it was the final hurrah for the X58 platform. It supports triple-channel DDR3 memory and provides 36 PCIe 2.0 lanes. With a 130W TDP, it required robust cooling. The i7-980 offered near-990X performance at a lower price point, making it an attractive option for enthusiasts who wanted maximum multi-threaded performance on the legacy platform. Although obsolete today, it stands as the peak of the LGA 1366 ecosystem, delivering excellent performance for 2011 era content creation and gaming.
The i7-980 was the last major release for LGA 1366. With a 3.333 GHz base and 3.
6 GHz turbo, it pushed the Gulftown architecture to its limits. It offered near-Extreme Edition performance for a lower price, making it a favorite for X58 enthusiasts before Sandy Bridge-E arrived.
Specifications

Architecture Overview
The Core i7-980 is based on the Gulftown die, a 32nm die-shrink of the Nehalem architecture. This process allowed Intel to fit 6 cores onto a single die, resulting in 12 logical threads via Hyper-Threading. The die houses 1.17 billion transistors across a 239 mm² die. Gulftown integrates a triple-channel DDR3 memory controller, providing massive memory bandwidth. It communicates with the X58 chipset via QPI and provides 36 PCIe 2.0 lanes for multi-GPU setups. The architecture features a large 12 MB shared L3 cache. Turbo Boost dynamically increases the clock from 3.333 GHz to 3.6 GHz under load. The 980 is essentially a higher-clocked i7-970, pushing the 32nm silicon to its frequency limits. Its 130W TDP reflects the power demands of 6 cores running at high frequencies. It was a fitting end to the LGA 1366 platform, maximizing its performance potential before the transition to LGA 2011.

History
The Core i7-980 launched in June 2011 as the final major release for the LGA 1366 platform. Intel sought to maximize the platform's potential before transitioning to the new LGA 2011 Sandy Bridge-E architecture. The 980 was essentially a higher-clocked i7-970, pushing the base clock to 3.
333 GHz. It offered performance very close to the legendary i7-990X Extreme Edition but at a lower price point. This made it a highly desirable chip for X58 enthusiasts looking for a final upgrade.
The 980 represented the end of an era for triple-channel memory and the Westmere architecture. While it was quickly overshadowed by the i7-3930K, the 980 remains a beloved chip for retro enthusiasts, representing the absolute peak of the X58 platform's capabilities before Intel moved on to a new socket and architecture.
Improvements over Previous Generation
- Higher base clock (3.333 GHz)
- Higher turbo clock (3.6 GHz)
- Same 12MB L3 cache
