CPU Comparison
Intel Core i7-980X vs Intel Core i7-990X
A side-by-side comparison of specs, performance and value. The Intel Core i7-980X, released in March 2010, marked a pivotal moment in desktop computing as the first six-core processor available to consumers. Based on the 32nm Gulftown architecture, it was a major leap forward from the 45nm Bloomfield chips, doubling the core count while maintaining the 130W TDP. It featured 12MB of L3 cache and Hyper-Threading, presenting 12 logical threads to the operating system. As an Extreme Edition chip, it came with an unlocked multiplier, making it a favorite among overclocking enthusiasts. The LGA 1366 socket and triple-channel DDR3 memory support ensured massive bandwidth for its time. Although long discontinued, the 980X remains historically significant for bringing hexa-core processing to the high-end desktop market, fundamentally changing how developers approached multi-threaded application design and parallel processing workloads.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Six cores help with basic tasks, but slow clocks limit modern productivity apps.
Capable for basic legacy tasks, but severely outpaced by modern hardware.
Gaming
Struggles with modern games due to low single-core IPC and lack of AVX2.
Slightly better than the 980X due to clocks, but still bottlenecks modern games.
Virtualization
Adequate for basic retro VM labs, but lacks modern I/O.
12 threads are still somewhat useful for basic VM labs.
Efficiency
Extremely poor efficiency by modern standards with a 130W TDP.
130W TDP remains highly inefficient compared to modern nodes.
