CPU Comparison
Intel Core i3-12100 vs Intel Core i3-8100
A side-by-side comparison of specs, performance and value. The Intel Core i3-12100 is a 4-core, 8-thread desktop processor introducing the Golden Cove architecture to the budget segment, featuring DDR4/DDR5 support, PCIe 5.0, and a bundled Laminar RM1 cooler.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles everyday office tasks and web applications with ease, but heavy multitasking will expose the 4-core limitation.
The lack of Hyper-Threading severely limits performance in heavily threaded office applications compared to newer 8-thread budget chips.
Gaming
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.
Paired with a strong discrete GPU, it can still handle older eSports titles, but modern AAA games will be heavily CPU bottlenecked.
Virtualization
Can run a single lightweight virtual machine, but lacks the core count for serious virtualization workloads.
4 threads is the absolute minimum for running a modern OS and a single light virtual machine.
Efficiency
Very power-efficient for a desktop processor, drawing little power at idle and scaling linearly under load.
The 14nm process is power-hungry compared to modern 7nm or 5nm alternatives, drawing 65W for modest performance.
Specialized Performance
AI / ML
- No dedicated AI acceleration hardware

Our Verdict on Each
The 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.
Read the full reviewA landmark chip in 2017 for bringing quad-core computing to the masses, but thoroughly outclassed by modern budget processors in every metric.
Best for: The only justifiable scenario for purchasing an Intel Core i3-8100 today is if you are repairing an existing LGA 1151 v2 system (like an office PC or a hand-me-down) and can find the CPU for under $20 on the used market. Even then, you must consider that the 8100 lacks Hyper-Threading, which severely limits its longevity in modern operating systems that are increasingly optimized for 8 or more threads. If you are building a new system, even the absolute cheapest new motherboard and CPU combo from AMD or Intel's 12th/13th gen will offer exponentially better performance, efficiency, and platform features like PCIe 4.0 or DDR5. Do not buy this CPU for gaming, as the lack of Turbo Boost and Hyper-Threading will cause severe stuttering in modern titles compared to a modern Ryzen 3.
