CPU Comparison
Core i7-980 vs Intel Core i7-990X
A side-by-side comparison of specs, performance and value. 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 Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Strong multi-core for legacy tasks.
Capable for basic legacy tasks, but severely outpaced by modern hardware.
Gaming
Better single-core than 970, holds up slightly better in games.
Slightly better than the 980X due to clocks, but still bottlenecks modern games.
Virtualization
Excellent for legacy VMs.
12 threads are still somewhat useful for basic VM labs.
Efficiency
130W TDP is very inefficient by modern standards.
130W TDP remains highly inefficient compared to modern nodes.
