Performance Compared

Productivity

Intel Core i3-10105

Easily handles word processing, spreadsheets, and web applications. Multi-threaded tasks like video encoding reveal its 4-core limitations.

Intel Core i3-1210065

Handles everyday office tasks and web applications with ease, but heavy multitasking will expose the 4-core limitation.

Gaming

Intel Core i3-10105

When paired with a dedicated GPU, it can handle 1080p eSports titles well, but it will bottleneck more demanding modern AAA games.

Intel Core i3-1210065

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

Intel Core i3-10105

Can run a lightweight VM or two, but 8 threads and 6MB of cache restrict complex virtualization setups.

Intel Core i3-1210045

Can run a single lightweight virtual machine, but lacks the core count for serious virtualization workloads.

Efficiency

Intel Core i3-10105

The 14nm process is less power-efficient than newer 10nm or 7nm competing chips, drawing more power per clock.

Intel Core i3-1210082

Very power-efficient for a desktop processor, drawing little power at idle and scaling linearly under load.

Our Verdict on Each

A solid entry-level processor that served as a reliable budget option in 2021, though it is now outpaced by newer architectures and limited by PCIe 3.0 and DDR4-2666 memory speeds.

Best for: Upgrading an existing LGA 1200 system on a very tight budget where the CPU can be found used at a steep discount.

Read the full review

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.
