CPU Comparison
Intel Core i7-940 vs Intel Core i3-12100F
A side-by-side comparison of specs, performance and value. The Intel Core i7-940 launched alongside the i7-920 in November 2008 as the step-up model in the inaugural Bloomfield lineup. Operating at a base clock of 2.93GHz with a turbo boost of 3.2GHz, it offered slightly higher out-of-the-box performance than the 920. It featured the same four-core, eight-thread configuration and 8MB of L3 cache. While it was a capable processor, it occupied an awkward middle ground. Its price was significantly higher than the 920, yet it didn't offer the unlocked multiplier of the Extreme Edition 965. This positioning made it a relatively rare sight in enthusiast builds, as most users either opted for the value of the 920 or waited for later refreshes. Nevertheless, it remains a part of the foundational Nehalem architecture that reintroduced Hyper-Threading and integrated memory controllers, setting the stage for Intel's dominance in the high-end desktop market for the next decade.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Slow by modern standards.
Matches the 12100 in all CPU-bound productivity tasks, handling office work and light creative loads well.
Gaming
Similar to the 920, bottlenecks modern games.
Performs identically to the i3-12100 in gaming, offering smooth 1080p esports performance but showing its 4-core limits in modern CPU-heavy titles.
Virtualization
Adequate for basic legacy VMs.
Can manage a couple of lightweight VMs or Docker containers, though 4 cores restrict serious virtualization use.
Efficiency
130W TDP is highly inefficient.
Slightly more efficient than the non-F variant due to the disabled iGPU silicon reducing idle and base power draw.
Specialized Performance

Our Verdict on Each
A capable but poor-value CPU at launch due to the 920's overclocking prowess. Today, it's a rare collector's item.
Best for: Completing a period-accurate 2008 retro build.
Read the full reviewThe i3-12100F is one of the best value processors Intel has ever produced for gamers. By removing the iGPU and dropping the price to $97 while keeping the outstanding Golden Cove cores, it dominated the budget build market in 2022.
Best for: The i3-12100F is the optimal choice for anyone building a dedicated gaming PC on a strict budget where a discrete graphics card is guaranteed. By saving $25 over the 12100, you can allocate those funds toward a better GPU, which will have a far greater impact on gaming frame rates than the integrated graphics you are giving up. Do not buy this processor if there is any chance you will need to run the system without a dedicated GPU, as a missing or failed graphics card will render the computer completely unusable.
