CPU Comparison
Intel Core i7-6700 vs Intel Core i3-12100
A side-by-side comparison of specs, performance and value. The Intel Core i7-6700 is a mainstream quad-core desktop processor that served as the backbone of the 6th Generation Skylake lineup. Released in 2015, it brought incremental but meaningful improvements over the previous Haswell generation, including higher IPC, improved integrated graphics, and the introduction of DDR4 memory support to the mainstream market. Operating at a base clock of 3.4 GHz and boosting up to 4.0 GHz, it delivered strong single-threaded performance ideal for gaming and everyday productivity. With four cores and eight threads, it handled the multitasking demands of the era effectively. The 65-watt TDP ensured it ran efficiently and coolly, making it a staple in millions of office and home PCs worldwide. The inclusion of Intel HD Graphics 530 allowed for smooth 4K video playback and basic media tasks without requiring a discrete GPU, cementing its reputation as a versatile, do-it-all processor for mainstream users.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles office workloads and multitasking without issues.
Handles everyday office tasks and web applications with ease, but heavy multitasking will expose the 4-core limitation.
Gaming
Good for 60fps gaming with a discrete GPU, but struggles with modern high-refresh titles.
Delivers playable 1080p frame rates in esports and older AAA titles when paired with a mid-range GPU, though 4 cores limit performance in modern CPU-heavy games.
Virtualization
Capable of running 1-2 light VMs.
Can run a single lightweight virtual machine, but lacks the core count for serious virtualization workloads.
Efficiency
Highly efficient 65W design.
Very power-efficient for a desktop processor, drawing little power at idle and scaling linearly under load.

Our Verdict on Each
A reliable and efficient quad-core CPU that was the gold standard for mainstream desktop computing in 2015, still capable of basic tasks today.
Best for: Upgrading an older LGA 1151 system for budget 1080p gaming.
Read the full reviewThe i3-12100 delivers exceptional single-threaded performance for its $122 price point, complete with an iGPU and a stock cooler, making it one of the most well-rounded budget desktop processors Intel has ever produced.
Best for: Buy the i3-12100 if you are building a budget desktop PC and want the peace of mind of having integrated graphics as a fallback, or if you do not plan to install a dedicated GPU. At its current street price, it is an excellent choice for office PCs, student workstations, and entry-level gaming rigs paired with a mid-range graphics card like the GTX 1660 Super or RX 6600. Avoid it only if you are certain you will never need the iGPU, as the 12100F offers identical CPU performance for less money.
